Problem installing PostgreSQL 12 on CentOS 8

Question

Installing PostgreSQL 12:

sudo dnf install @postgresql:12

Then, contrib package for additional features: sudo dnf install postgresql-contrib

Afterwards, when I try to initialize the PostgreSQL database:

sudo postgresql-setup initdb

I'm getting: sudo: postgresql-setup: command not found

Also, when I try to check the status:

 sudo systemctl status postgresql

Getting this error: Unit postgresql.service could not be found.

What I'm doing wrong? If this way of installing is wrong, is there another option to install postgresql on centos?

Answer 1

You have only installed the PostgreSQL client application on your server. In order to install the server software, you need to install the postgresql-server package which will satisfy those package dependencies. Afterwards you can follow this documentation to continue provisioning, configuring, and maintaining your new database.

This gist of which, as you originally mentioned, is simply:

  postgresql-setup initdb
  systemctl enable postgresql.service --now
