The commands to configure Postgres database are different for CentOS, Debian, and Ubuntu. Refer to the respective section to view the procedure for your platform.

  1. Install the supported version of Postgres using the following commands:
    yum install
    yum install postgresql96-contrib postgresql96-server
    For more information about the supported version of Postgres, see the DAS Support Matrix.
  2. Initialize the Postgres database by running the following command:
    /usr/pgsql-9.6/bin/postgresql96-setup initdb
  3. Open the pg_hba.conf file for editing by entering the following command:
    vi /var/lib/pgsql/9.6/data/pg_hba.conf
  4. Add lines similar to the following lines:
    local   all             <dbuser>                              md5
    host    all             <dbuser>               md5
    host    all             <dbuser>      ::/0                    md5
    local   all             postgres         ident
  5. Open the postgresql.conf file for editing.
    vi /var/lib/pgsql/9.6/data/postgresql.conf
  6. Add, update, or uncomment the listen_addresses line as follows:
    listen_addresses = '*'
  7. Start the Postgres database by running the following command:
    service postgresql-9.6 start

    Wait for the command to finish in some time or kill the command if it does not respond.

  8. Create roles in Postgres by running the following commands as a Postgres user:
    psql -tc "SELECT 1 FROM pg_database WHERE datname = <dbname>" | grep 1 || (
    psql -c "CREATE ROLE <dbuser> WITH LOGIN PASSWORD <dbpass>;" &&
    psql -c "ALTER ROLE <dbuser> CREATEDB;" &&
    psql -c "CREATE DATABASE <dbname>;" &&
    psql -c "GRANT ALL PRIVILEGES ON DATABASE <dbname> TO <dbuser>;")

    Replace <dbname> with the database name, <dbuser> with the database username and <dbpass> with the database password.
