Unable to start postgresql service on CentOS 7

Question

Unable to start postgresql-9.5 on CentOS 7.

I followed this page - https://wiki.postgresql.org/wiki/YUM_Installation - for installing the database server on CentOS.

Answer 1

The most common issue is that the database cluster was not initialized. You can initialize it easily by running the postgresql-XX-setup script with the initdb command, e.g.

sudo /usr/pgsql-11/bin/postgresql-11-setup initdb

Then start the Postgres service, e.g.

sudo systemctl start postgresql-11
