Install Postgres

If you have already installed a MySQL database, you may skip these steps.


You must install Postgres 9.5 or later for SAM and Schema Registry. Ambari does not install Postgres 9.5, so you must perform a manual Postgres installation.

  1. Install Red Hat Package Manager (RPM) according to the requirements of your operating system:
    yum install
  2. Install Postgres version 9.5 or later:
    yum install postgresql96-server postgresql96-contrib postgresql96
  3. Initialize the database:
    For CentOS 7, use the following syntax:
    /usr/pgsql-9.6/bin/postgresql96-setup initdb
  4. Start Postgres.

    For example, if you are using CentOS 7, use the following syntax:

    systemctl enable postgresql-9.6.service
    systemctl start postgresql-9.6.service 
  5. Verify that you can log in:
    sudo su postgres
