Issue/Introduction

So I started process again and now I'm having the following issue.

 

[postgres@xxx data]$ cd /usr/pgsql-13/bin

[postgres@xxx bin]$ ./initdb -D /opt/apm/pgsql/13/data

The files belonging to this database system will be owned by user "postgres".

This user must also own the server process.

 

The database cluster will be initialized with locale "en_US.UTF-8".

The default database encoding has accordingly been set to "UTF8".

The default text search configuration will be set to "english".

 

Data page checksums are disabled.

initdb: warning: enabling "trust" authentication for local connections

You can change this by editing pg_hba.conf or using the option -A, or

--auth-local and --auth-host, the next time you run initdb.

 

Success. You can now start the database server using:

 

    ./pg_ctl -D /opt/apm/pgsql/13/data -l logfile start

 

[root@xxx bin]# sudo systemctl start postgresql-13

Job for postgresql-13.service failed because the control process exited with error code.

See "systemctl status postgresql-13.service" and "journalctl -xe" for details.

 

Environment

Release : 10.7.0

Resolution

Found this doc that may help https://unix.stackexchange.com/questions/294926/unable-to-start-posgtresql-the-reason-isnt-clear

Also provide output for See "systemctl status postgresql-13.service" and "journalctl -xe" for details.

So I edited file /etc/systemd/system/postgresql-13.service where it was showing the following before I edited it.

 

# Location of database directory

Environment=PGDATA=/var/lib/pgsql/13/data/

 

[root@jtcqa1lapmom01 system]# sudo systemctl status postgresql-13
