Edit the PostgreSQL configuration file pg_hba.conf located in /etc/postgresql/12/main to verify that peer authentication is enabled.Sudo apt-get install postgresql-12 postgresql-client-12 -y -no-install-recommends PostgreSQL is installed in the following directories: /usr/lib/postgresql/12/bin, /var/lib/postgresql/12, /etc/postgresql/12/main. Import the repository signing key, and update the package lists.Sudo sh -c "echo 'deb bionic-pgdg main' > /etc/apt//pgdg.list" Add the path of the Debian distribution repository for PostgreSQL to the end of the file /etc/apt//pgdg.list, creating it if it doesn't exist.Confirm the environment variable LANG is set to en_US.UTF-8.Verify that the command line tool for managing packages, Advanced Packaging Tool (APT), or apt-get, is available.These PostgreSQL 12 installation instructions are based on instructions from the PostgreSQL API Repository, or APT, which maintains the PostgreSQL Global Development Group (PGDG) packages. Ln -s /data/pgdata /var/lib/pgsql/12/data As the user postgres, remove the directory /var/lib/pgsql/12/data and create a soft link to the directory /data/pgdata.As the user postgres, change to the directory /var/lib/pgsql/12/data and copy all files within to the directory /data/pgdata.Ensure the required permissions on the directory.Sudo chown postgres:postgres /data/pgdata Create a non-default directory for PGDATA, such as /data/pgdata, and change its user and group to postgres.To configure a non-default value for PGDATA via a soft-link: You can change it to a different value by soft linking the directory.Ĭheck that you have installed PostgreSQL.
