PostgreSQL Installation Instructions This document describes the installation of PostgreSQL from the source code distribution. _________________________________________________________________ Short Version ./configure gmake su gmake install adduser postgres mkdir /usr/local/pgsql/data chown postgres /usr/local/pgsql/data su - postgres /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data >logfile 2>&1 & /usr/local/pgsql/bin/createdb test /usr/local/pgsql/bin/psql test The long version is the rest of this document. _________________________________________________________________ Requirements In general, a modern Unix-compatible platform should be able to run PostgreSQL. The platforms that had received specific testing at the time of release are listed in the section called Supported Platforms below. In the "doc" subdirectory of the distribution there are several platform-specific FAQ documents you might wish to consult if you are having trouble. The following software packages are required for building PostgreSQL: * GNU make is required; other make programs will *not* work. GNU make is often installed under the name "gmake"; this document will always refer to it by that name. (On some systems GNU make is the default tool with the name "make".) To test for GNU make enter gmake --version It is recommended to use version 3.76.1 or later. * You need an ISO/ANSI C compiler. Recent versions of GCC are recommendable, but PostgreSQL is known to build with a wide variety of compilers from different vendors. * gzip is needed to unpack the distribution in the first place. If you are reading this, you probably already got past that hurdle. * The GNU Readline library (for comfortable line editing and command history retrieval) will be used by default. If you don't want to use it then you must specify the "--without-readline" option for "configure". (On NetBSD, the "libedit" library is Readline-compatible and is used if "libreadline" is not found.) * To build on Windows NT or Windows 2000 you need the Cygwin and cygipc packages. See the file "doc/FAQ_MSWIN" for details. The following packages are optional. They are not required in the default configuration, but they are needed when certain build options are enabled, as explained below. * To build the server programming language PL/Perl you need a full Perl installation, including the "libperl" library and the header files. Since PL/Perl will be a shared library, the "libperl" library must be a shared library also on most platforms. This appears to be the default in recent Perl versions, but it was not in earlier versions, and in general it is the choice of whomever installed Perl at your site. If you don't have the shared library but you need one, a message like this will appear during the build to point out this fact: *** Cannot build PL/Perl because libperl is not a shared library. *** You might have to rebuild your Perl installation. Refer to *** the documentation for details. (If you don't follow the on-screen output you will merely notice that the PL/Perl library object, "plperl.so" or similar, will not be installed.) If you see this, you will have to rebuild and install Perl manually to be able to build PL/Perl. During the configuration process for Perl, request a shared library. * To build the PL/Python server programming language, you need a Python installation, including the header files. Since PL/Python will be a shared library, the "libpython" library must be a shared library also on most platforms. This is not the case in a default Python installation. If after building and installing you have a file called "plpython.so" (possibly a different extension), then everything went well. Otherwise you should have seen a notice like this flying by: *** Cannot build PL/Python because libpython is not a shared library. *** You might have to rebuild your Python installation. Refer to *** the documentation for details. That means you have to rebuild (part of) your Python installation to supply this shared library. The catch is that the Python distribution or the Python maintainers do not provide any direct way to do this. The closest thing we can offer you is the information in Python FAQ 3.30. On some operating systems you don't really have to build a shared library, but then you will have to convince the PostgreSQL build system of this. Consult the "Makefile" in the "src/pl/plpython" directory for details. * If you want to build Tcl or Tk components (clients and the PL/Tcl language) you of course need a Tcl installation. * To build the JDBC driver, you need Ant 1.5 or higher and a JDK. Ant is a special tool for building Java-based packages. It can be downloaded from the Ant web site. If you have several Java compilers installed, it depends on the Ant configuration which one gets used. Precompiled Ant distributions are typically set up to read a file ".antrc" in the current user's home directory for configuration. For example, to use a different JDK than the default, this may work: JAVA_HOME=/usr/local/sun-jdk1.3 JAVACMD=$JAVA_HOME/bin/java Note: Do not try to build the driver by calling "ant" or even "javac" directly. This will not work. Run "gmake" normally as described below. * To enable Native Language Support (NLS), that is, the ability to display a program's messages in a language other than English, you need an implementation of the Gettext API. Some operating systems have this built-in (e.g., Linux, NetBSD, Solaris), for other systems you can download an add-on package from here: http://www.postgresql.org/~petere/gettext.html. If you are using the Gettext implementation in the GNU C library then you will additionally need the GNU Gettext package for some utility programs. For any of the other implementations you will not need it. * Kerberos, OpenSSL, or PAM, if you want to support authentication using these services. If you are building from a CVS tree instead of using a released source package, or if you want to do development, you also need the following packages: * Flex and Bison are needed to build a CVS checkout or if you changed the actual scanner and parser definition files. If you need them, be sure to get Flex 2.5.4 or later and Bison 1.875 or later. Other yacc programs can sometimes be used, but doing so requires extra effort and is not recommended. Other lex programs will definitely not work. If you need to get a GNU package, you can find it at your local GNU mirror site (see http://www.gnu.org/order/ftp.html for a list) or at ftp://ftp.gnu.org/gnu/. Also check that you have sufficient disk space. You will need about 65 MB for the source tree during compilation and about 15 MB for the installation directory. An empty database cluster takes about 25 MB, databases take about five times the amount of space that a flat text file with the same data would take. If you are going to run the regression tests you will temporarily need up to an extra 90 MB. Use the "df" command to check for disk space. _________________________________________________________________ If You Are Upgrading The internal data storage format changes with new releases of PostgreSQL. Therefore, if you are upgrading an existing installation that does not have a version number "7.4.x", you must back up and restore your data as shown here. These instructions assume that your existing installation is under the "/usr/local/pgsql" directory, and that the data area is in "/usr/local/pgsql/data". Substitute your paths appropriately. 1. Make sure that your database is not updated during or after the backup. This does not affect the integrity of the backup, but the changed data would of course not be included. If necessary, edit the permissions in the file "/usr/local/pgsql/data/pg_hba.conf" (or equivalent) to disallow access from everyone except you. 2. To back up your database installation, type: pg_dumpall > outputfile If you need to preserve OIDs (such as when using them as foreign keys), then use the "-o" option when running "pg_dumpall". "pg_dumpall" does not save large objects. Check the documentation if you need to do this. To make the backup, you can use the "pg_dumpall" command from the version you are currently running. For best results, however, try to use the "pg_dumpall" command from PostgreSQL 7.4beta4, since this version contains bug fixes and improvements over older versions. While this advice might seem idiosyncratic since you haven't installed the new version yet, it is advisable to follow it if you plan to install the new version in parallel with the old version. In that case you can complete the installation normally and transfer the data later. This will also decrease the downtime. 3. If you are installing the new version at the same location as the old one then shut down the old server, at the latest before you install the new files: kill -INT `cat /usr/local/pgsql/data/postmaster.pid` Versions prior to 7.0 do not have this "postmaster.pid" file. If you are using such a version you must find out the process ID of the server yourself, for example by typing "ps ax | grep postmaster", and supply it to the "kill" command. On systems that have PostgreSQL started at boot time, there is probably a start-up file that will accomplish the same thing. For example, on a Red Hat Linux system one might find that /etc/rc.d/init.d/postgresql stop works. Another possibility is "pg_ctl stop". 4. If you are installing in the same place as the old version then it is also a good idea to move the old installation out of the way, in case you have trouble and need to revert to it. Use a command like this: mv /usr/local/pgsql /usr/local/pgsql.old After you have installed PostgreSQL 7.4beta4, create a new database directory and start the new server. Remember that you must execute these commands while logged in to the special database user account (which you already have if you are upgrading). /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data Finally, restore your data with /usr/local/pgsql/bin/psql -d template1 -f outputfile using the *new* psql. These topics are discussed at length in the documentation, which you are encouraged to read in any case. _________________________________________________________________ Installation Procedure 1. Configuration The first step of the installation procedure is to configure the source tree for your system and choose the options you would like. This is done by running the "configure" script. For a default installation simply enter ./configure This script will run a number of tests to guess values for various system dependent variables and detect some quirks of your operating system, and finally will create several files in the build tree to record what it found. (You can also run "configure" in a directory outside the source tree if you want to keep the build directory separate.) The default configuration will build the server and utilities, as well as all client applications and interfaces that require only a C compiler. All files will be installed under "/usr/local/pgsql" by default. You can customize the build and installation process by supplying one or more of the following command line options to "configure": --prefix=PREFIX Install all files under the directory "PREFIX" instead of "/usr/local/pgsql". The actual files will be installed into various subdirectories; no files will ever be installed directly into the "PREFIX" directory. If you have special needs, you can also customize the individual subdirectories with the following options. --exec-prefix=EXEC-PREFIX You can install architecture-dependent files under a different prefix, "EXEC-PREFIX", than what "PREFIX" was set to. This can be useful to share architecture-independent files between hosts. If you omit this, then "EXEC-PREFIX" is set equal to "PREFIX" and both architecture-dependent and independent files will be installed under the same tree, which is probably what you want. --bindir=DIRECTORY Specifies the directory for executable programs. The default is "EXEC-PREFIX/bin", which normally means "/usr/local/pgsql/bin". --datadir=DIRECTORY Sets the directory for read-only data files used by the installed programs. The default is "PREFIX/share". Note that this has nothing to do with where your database files will be placed. --sysconfdir=DIRECTORY The directory for various configuration files, "PREFIX/etc" by default. --libdir=DIRECTORY The location to install libraries and dynamically loadable modules. The default is "EXEC-PREFIX/lib". --includedir=DIRECTORY The directory for installing C and C++ header files. The default is "PREFIX/include". --docdir=DIRECTORY Documentation files, except "man" pages, will be installed into this directory. The default is "PREFIX/doc". --mandir=DIRECTORY The man pages that come with PostgreSQL will be installed under this directory, in their respective "manx" subdirectories. The default is "PREFIX/man". Note: Care has been taken to make it possible to install PostgreSQL into shared installation locations (such as "/usr/local/include") without interfering with the namespace of the rest of the system. First, the string "/postgresql" is automatically appended to datadir, sysconfdir, and docdir, unless the fully expanded directory name already contains the string "postgres" or "pgsql". For example, if you choose "/usr/local" as prefix, the documentation will be installed in "/usr/local/doc/postgresql", but if the prefix is "/opt/postgres", then it will be in "/opt/postgres/doc". The public C header files of the client interfaces are installed into includedir and are namespace-clean. The internal header files and the server header files are installed into private directories under includedir. See the documentation of each interface for information about how to get at the its header files. Finally, a private subdirectory will also be created, if appropriate, under libdir for dynamically loadable modules. --with-includes=DIRECTORIES "DIRECTORIES" is a colon-separated list of directories that will be added to the list the compiler searches for header files. If you have optional packages (such as GNU Readline) installed in a non-standard location, you have to use this option and probably also the corresponding "--with-libraries" option. Example: --with-includes=/opt/gnu/include:/usr/sup/include. --with-libraries=DIRECTORIES "DIRECTORIES" is a colon-separated list of directories to search for libraries. You will probably have to use this option (and the corresponding "--with-includes" option) if you have packages installed in non-standard locations. Example: --with-libraries=/opt/gnu/lib:/usr/sup/lib. --enable-nls[=LANGUAGES] Enables Native Language Support (NLS), that is, the ability to display a program's messages in a language other than English. "LANGUAGES" is a space separated list of codes of the languages that you want supported, for example --enable-nls='de fr'. (The intersection between your list and the set of actually provided translations will be computed automatically.) If you do not specify a list, then all available translations are installed. To use this option, you will need an implementation of the Gettext API; see above. --with-pgport=NUMBER Set "NUMBER" as the default port number for server and clients. The default is 5432. The port can always be changed later on, but if you specify it here then both server and clients will have the same default compiled in, which can be very convenient. Usually the only good reason to select a non-default value is if you intend to run multiple PostgreSQL servers on the same machine. --with-perl Build the PL/Perl server-side language. --with-python Build the PL/Python server-side language. --with-tcl Build components that require Tcl/Tk, which are libpgtcl, pgtclsh, pgtksh, and PL/Tcl. But see below about "--without-tk". --without-tk If you specify "--with-tcl" and this option, then the program that requires Tk (pgtksh) will be excluded. --with-tclconfig=DIRECTORY, --with-tkconfig=DIRECTORY Tcl/Tk installs the files "tclConfig.sh" and "tkConfig.sh", which contain configuration information needed to build modules interfacing to Tcl or Tk. These files are normally found automatically at their well-known locations, but if you want to use a different version of Tcl or Tk you can specify the directory in which to find them. --with-java Build the JDBC driver and associated Java packages. --with-krb4[=DIRECTORY], --with-krb5[=DIRECTORY] Build with support for Kerberos authentication. You can use either Kerberos version 4 or 5, but not both. The "DIRECTORY" argument specifies the root directory of the Kerberos installation; "/usr/athena" is assumed as default. If the relevant header files and libraries are not under a common parent directory, then you must use the "--with-includes" and "--with-libraries" options in addition to this option. If, on the other hand, the required files are in a location that is searched by default (e.g., "/usr/lib"), then you can leave off the argument. "configure" will check for the required header files and libraries to make sure that your Kerberos installation is sufficient before proceeding. --with-krb-srvnam=NAME The name of the Kerberos service principal. postgres is the default. There's probably no reason to change this. --with-openssl[=DIRECTORY] Build with support for SSL (encrypted) connections. This requires the OpenSSL package to be installed. The "DIRECTORY" argument specifies the root directory of the OpenSSL installation; the default is "/usr/local/ssl". "configure" will check for the required header files and libraries to make sure that your OpenSSL installation is sufficient before proceeding. --with-pam Build with PAM (Pluggable Authentication Modules) support. --without-readline Prevents the use of the Readline library. This disables command-line editing and history in psql, so it is not recommended. --with-rendezvous Build with Rendezvous support. --disable-spinlocks Allows source builds to succeed without CPU spinlock support. Lack of spinlock support will produce poor performance. This option is to be used only by platforms lacking spinlock support. --enable-thread-safety Allow separate libpq and ecpg threads to safely control their private connection handles. --without-zlib Prevents the use of the Zlib library. This disables compression support in pg_dump. This option is only intended for those rare systems where this library is not available. --enable-debug Compiles all programs and libraries with debugging symbols. This means that you can run the programs through a debugger to analyze problems. This enlarges the size of the installed executables considerably, and on non-GCC compilers it usually also disables compiler optimization, causing slowdowns. However, having the symbols available is extremely helpful for dealing with any problems that may arise. Currently, this option is recommended for production installations only if you use GCC. But you should always have it on if you are doing development work or running a beta version. --enable-cassert Enables assertion checks in the server, which test for many "can't happen" conditions. This is invaluable for code development purposes, but the tests slow things down a little. Also, having the tests turned on won't necessarily enhance the stability of your server! The assertion checks are not categorized for severity, and so what might be a relatively harmless bug will still lead to server restarts if it triggers an assertion failure. Currently, this option is not recommended for production use, but you should have it on for development work or when running a beta version. --enable-depend Enables automatic dependency tracking. With this option, the makefiles are set up so that all affected object files will be rebuilt when any header file is changed. This is useful if you are doing development work, but is just wasted overhead if you intend only to compile once and install. At present, this option will work only if you use GCC. If you prefer a C compiler different from the one "configure" picks then you can set the environment variable CC to the program of your choice. By default, "configure" will pick "gcc" unless this is inappropriate for the platform. Similarly, you can override the default compiler flags with the CFLAGS variable. You can specify environment variables on the "configure" command line, for example: ./configure CC=/opt/bin/gcc CFLAGS='-O2 -pipe' 2. Build To start the build, type gmake (Remember to use GNU make.) The build may take anywhere from 5 minutes to half an hour depending on your hardware. The last line displayed should be All of PostgreSQL is successfully made. Ready to install. 3. Regression Tests If you want to test the newly built server before you install it, you can run the regression tests at this point. The regression tests are a test suite to verify that PostgreSQL runs on your machine in the way the developers expected it to. Type gmake check (This won't work as root; do it as an unprivileged user.) It is possible that some tests fail, due to differences in error message wording or floating point results. The file "src/test/regress/README" and the documentation contain detailed information about interpreting the test results. You can repeat this test at any later time by issuing the same command. 4. Installing The Files Note: If you are upgrading an existing system and are going to install the new files over the old ones, then you should have backed up your data and shut down the old server by now, as explained in the section called If You Are Upgrading above. To install PostgreSQL enter gmake install This will install files into the directories that were specified in step 1. Make sure that you have appropriate permissions to write into that area. Normally you need to do this step as root. Alternatively, you could create the target directories in advance and arrange for appropriate permissions to be granted. You can use gmake install-strip instead of gmake install to strip the executable files and libraries as they are installed. This will save some space. If you built with debugging support, stripping will effectively remove the debugging support, so it should only be done if debugging is no longer needed. install-strip tries to do a reasonable job saving space, but it does not have perfect knowledge of how to strip every unneeded byte from an executable file, so if you want to save all the disk space you possibly can, you will have to do manual work. The standard installation provides only the header files needed for client application development. If you plan to do any server-side program development (such as custom functions or data types written in C), then you may want to install the entire PostgreSQL include tree into your target include directory. To do that, enter gmake install-all-headers This adds a megabyte or two to the installation footprint, and is only useful if you don't plan to keep the whole source tree around for reference. (If you do, you can just use the source's include directory when building server-side software.) Client-only installation: If you want to install only the client applications and interface libraries, then you can use these commands: gmake -C src/bin install gmake -C src/include install gmake -C src/interfaces install gmake -C doc install Uninstallation: To undo the installation use the command "gmake uninstall". However, this will not remove any created directories. Cleaning: After the installation you can make room by removing the built files from the source tree with the command "gmake clean". This will preserve the files made by the "configure" program, so that you can rebuild everything with "gmake" later on. To reset the source tree to the state in which it was distributed, use "gmake distclean". If you are going to build for several platforms from the same source tree you must do this and re-configure for each build. If you perform a build and then discover that your "configure" options were wrong, or if you change anything that "configure" investigates (for example, software upgrades), then it's a good idea to do "gmake distclean" before reconfiguring and rebuilding. Without this, your changes in configuration choices may not propagate everywhere they need to. _________________________________________________________________ Post-Installation Setup Tuning By default, PostgreSQL is configured to run on minimal hardware. This allows it to start up with almost any hardware configuration. However, the default configuration is not designed for optimum performance. To achieve optimum performance, several server variables must be adjusted, the two most common being shared_buffers and sort_mem mentioned in the documentation . Other parameters in the documentation also affect performance. _________________________________________________________________ Shared Libraries On some systems that have shared libraries (which most systems do) you need to tell your system how to find the newly installed shared libraries. The systems on which this is *not* necessary include BSD/OS, FreeBSD, HP-UX, IRIX, Linux, NetBSD, OpenBSD, Tru64 UNIX (formerly Digital UNIX), and Solaris. The method to set the shared library search path varies between platforms, but the most widely usable method is to set the environment variable LD_LIBRARY_PATH like so: In Bourne shells ("sh", "ksh", "bash", "zsh") LD_LIBRARY_PATH=/usr/local/pgsql/lib export LD_LIBRARY_PATH or in "csh" or "tcsh" setenv LD_LIBRARY_PATH /usr/local/pgsql/lib Replace /usr/local/pgsql/lib with whatever you set "--libdir" to in step 1. You should put these commands into a shell start-up file such as "/etc/profile" or "~/.bash_profile". Some good information about the caveats associated with this method can be found at http://www.visi.com/~barr/ldpath.html. On some systems it might be preferable to set the environment variable LD_RUN_PATH *before* building. On Cygwin, put the library directory in the PATH or move the ".dll" files into the "bin" directory. If in doubt, refer to the manual pages of your system (perhaps "ld.so" or "rld"). If you later on get a message like psql: error in loading shared libraries libpq.so.2.1: cannot open shared object file: No such file or directory then this step was necessary. Simply take care of it then. If you are on BSD/OS, Linux, or SunOS 4 and you have root access you can run /sbin/ldconfig /usr/local/pgsql/lib (or equivalent directory) after installation to enable the run-time linker to find the shared libraries faster. Refer to the manual page of "ldconfig" for more information. On FreeBSD, NetBSD, and OpenBSD the command is /sbin/ldconfig -m /usr/local/pgsql/lib instead. Other systems are not known to have an equivalent command. _________________________________________________________________ Environment Variables If you installed into "/usr/local/pgsql" or some other location that is not searched for programs by default, you should add "/usr/local/pgsql/bin" (or whatever you set "--bindir" to in step 1) into your PATH. Strictly speaking, this is not necessary, but it will make the use of PostgreSQL much more convenient. To do this, add the following to your shell start-up file, such as "~/.bash_profile" (or "/etc/profile", if you want it to affect every user): PATH=/usr/local/pgsql/bin:$PATH export PATH If you are using "csh" or "tcsh", then use this command: set path = ( /usr/local/pgsql/bin $path ) To enable your system to find the man documentation, you need to add lines like the following to a shell start-up file unless you installed into a location that is searched by default. MANPATH=/usr/local/pgsql/man:$MANPATH export MANPATH The environment variables PGHOST and PGPORT specify to client applications the host and port of the database server, overriding the compiled-in defaults. If you are going to run client applications remotely then it is convenient if every user that plans to use the database sets PGHOST. This is not required, however: the settings can be communicated via command line options to most client programs. _________________________________________________________________ Getting Started The following is a quick summary of how to get PostgreSQL up and running once installed. The main documentation contains more information. 1. Create a user account for the PostgreSQL server. This is the user the server will run as. For production use you should create a separate, unprivileged account ("postgres" is commonly used). If you do not have root access or just want to play around, your own user account is enough, but running the server as root is a security risk and will not work. adduser postgres 2. Create a database installation with the "initdb" command. To run "initdb" you must be logged in to your PostgreSQL server account. It will not work as root. root# mkdir /usr/local/pgsql/data root# chown postgres /usr/local/pgsql/data root# su - postgres postgres$ /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data The "-D" option specifies the location where the data will be stored. You can use any path you want, it does not have to be under the installation directory. Just make sure that the server account can write to the directory (or create it, if it doesn't already exist) before starting "initdb", as illustrated here. 3. The previous step should have told you how to start up the database server. Do so now. The command should look something like /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data This will start the server in the foreground. To put the server in the background use something like nohup /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data \ >server.log 2>&1 or , not to the people listed here.
