- These instructions are intended specifically for installing PostgreSQL on CentOS 6.
- I’ll be working from a Liquid Web Core Managed CentOS 6.5 server, and I’ll be logged in as root.
Step 1: Install PostgreSQLFirst, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new.
yum -y updateThen it’s a matter of just running one command for installation via yum:
yum -y install postgresql postgresql-contribPostgreSQL should now be installed.
Step 2: Start PostgreSQLConfigure Postgres to start when the server boots:
chkconfig postgresql onStart Postgres:
service postgresql initdb
service postgresql start
Step 3: Switch to the Default PostgreSQL UserAs part of the installation Postgres adds the system user postgres and is setup to use “ident” authentication. Roles internal to Postgres (which are similar to users) match with a system user account. Let’s switch into that system user:
su – postgresAnd then connect to the PostgreSQL terminal (in the postgres role):
psqlThat’s it! You’re connected and ready to run commands in PostgreSQL as the postgres role. In future (Sept 2014) articles we’ll delve into creating new roles, changing a role’s password, creating/deleting databases, backups, etc.
