Config PostgreSQL in CentOS7 2020-04-17 09:53

It is no way to use service postgresql-9.4 initdb init PostgreSQL in CentOS7. I use following commends.

[root@my_computer ~]# systemctl enable postgresql-9.4
Created symlink from /etc/systemd/system/ to /usr/lib/systemd/system/postgresql-9.4.service.
[root@my_computer ~]# /usr/pgsql-9.4/bin/postgres initdb
postgres                   postgresql94-check-db-dir  postgresql94-setup         
[root@my_computer ~]# /usr/pgsql-9.4/bin/postgresql94-setup initdb
Initializing database ... OK
[root@my_computer ~]# systemctl start postgresql-9.4
[root@my_computer ~]# su - postgres
-bash-4.2$ psql
psql (9.4.26)
Type "help" for help.


Now you can execute sql in the terminal.
