PostgreSQL can be installed using RPMs (binary) or SRPMs (source) managed by YUM. This is available for the following Linux distributions (both 32- and 64-bit platforms; for the current release and prior release or two):
- Fedora
- Red Hat Enterprise Linux
- CentOS
- Scientific Linux (EOLed)
- Oracle Enterprise Linux

Instructions
Configure your YUM repository
Locate and edit your distributions .repo file, located:
- On Fedora: /etc/yum.repos.d/fedora.repo and /etc/yum.repos.d/fedora-updates.repo, [fedora] sections
- On CentOS: /etc/yum.repos.d/CentOS-Base.repo, [base] and [updates] sections
- On Red Hat: /etc/yum/pluginconf.d/rhnplugin.conf [main] section
To the section(s) identified above, you need to append a line (otherwise dependencies might resolve to the postgresql supplied by the base repository):
exclude=postgresql*
Install PGDG RPM file
A PGDG file is available for each distribution Browse https://yum.postgresql.org/repopackages.php and find your correct RPM. There is only one single repo RPM for all PostgreSQL versions for each platform.
Install PostgreSQL
To list available packages:
yum list postgresql*
For example, to install a basic PostgreSQL 9.6 server:
yum install postgresql96-server
Other packages can be installed according to your needs.
Post-installation commands
After installing the packages, a database needs to be initialized and configured.
In the commands below, the value of <name> will vary depending on the version of PostgreSQL used.
For PostgreSQL versions from 9.4 to 9.6, the <name> includes the major.minor version of PostgreSQL, e.g., 9.6
For PostgreSQL versions from 10 and above, the <name> includes the major version of PostgreSQL, e.g., 10
Data Directory
The PostgreSQL data directory contains all of the data files for the database. The variable PGDATA is used to reference this directory.
The default data directory is:
/var/lib/pgsql/<name>/data
For example:
/var/lib/pgsql/9.6/data
Initialize
The first command (only needed once) is to initialize the database in PGDATA.
For Red Hat 6:
service <name> initdb
E.g. for version 9.6:
service postgresql-9.6 initdb
For Red Hat 7, and Fedora 29 and above:
If the previous command did not work, try directly calling the setup binary, located in a similar naming scheme:
/usr/pgsql-y.x/bin/postgresqlyx-setup initdb
E.g. for version 9.6:
/usr/pgsql-9.6/bin/postgresql96-setup initdb
For versions 10 and above:
/usr/pgsql-9.6/bin/postgresql-10-setup initdb (Notice the extra dash before major version)
Startup
If you want PostgreSQL to start automatically when the OS starts, do the following:
In RHEL 6 and PostgreSQL 9.6:
chkconfig postgresql-9.6 on
In RHEL 7+, and Fedora 23+ try:
systemctl enable postgresql-9.6.service
Control service
To control the database service, use:
for RHEL 5 and 6:
service <name> <command>
where <command> can be:
- start : start the database
- stop : stop the database
- restart : stop/start the database; used to read changes to core configuration files
- reload : reload pg_hba.conf file while keeping database running
E.g. to start version 9.6:
service postgresql-9.6 start
With RHEL 7.1+ and CentOS 7.1+, and Fedora 23+, systemd is introduced. Use this instead:
systemctl enable postgresql-9.6.service systemctl start postgresql-9.6.service
Removing
To remove everything:
yum erase postgresql96* or dnf remove postgresql96* for Fedora 23+.
Or remove individual packages as desired.
