Install PostgreSQL
To list available packages:
zypper packages -N pg
For example, to install a basic PostgreSQL 9.4 server:
zypper install postgresql94-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 version 9.0 and above, the <name> includes the major.minor version of PostgreSQL, e.g., postgresql-9.4
Data Directory
The PostgreSQL data directory contains all of the data files for the database. The variable PGDATA is used to reference this directory.
For PostgreSQL version 9.0 and above, the default data directory is:
/var/lib/pgsql/<name>/data
For example:
/var/lib/pgsql/9.4/data
Initialize
The first command (only needed once) is to initialize the database in PGDATA.
service <name> initdb
E.g. for version 9.4:
service postgresql-9.4 initdb
Startup
If you want PostgreSQL to start automatically when the OS starts:
chkconfig <name> on
E.g. for version 9.4:
chkconfig postgresql-9.4 on
Control service
To control the database service, use:
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 9.4:
service postgresql-9.4 start
