    • postgresql10

    • libecpg6

    • The client packages, if not automatically added with the server packages.

  5. Click Accept.

    BASIC VIBE INSTALLATION SUMMARY SHEET

    Under Database Credentials on the Single-server Installation Planning Worksheet, record the postgres administrator password. If you want to use a password other than postgres you must modify the postgresql-create-empty-database.sql file. See the PostgreSQL documentation on the web for help.

  13. Continue with Configuring the Socket Connection Method.

10.3.2 Configuring the Socket Connection Method

  1. As the root user, browse to /var/lib/pgsql/data.

    local  all   all                  md5
host   all   all   127.0.0.1/32   md5
host   all   all   ::1/128        md5
host   all   all   0.0.0.0/0      md5

    For more information about the pg_hba.conf file, see the PostgreSQL documentation on the web.

  3. Save the file.

  4. Edit the postgresql.conf file.

  5. Uncomment the listen_addresses line by removing the pound sign (#).
