如何在centos7上为PostgreSQL 9.2运行initdb？

Question

So,

My admin installed (don't know how) postgresql 9.2 (64 bit version) on a centos7 machine. The thing is I need to initalize the database so I should run something like:

service postgresql-9.2 initdb

but I get error:

The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl.

Did some search and people said that you should initialize via direct call to some script, but every given location does not exists in this CentOS 7 machine.

Like for example this location (yeah, it is for 9.3 and I use 9.2, but similar location does not exist anyway):

/usr/lib/pgsql-9.3/bin/postgresql93-setup initdb

or this

/usr/pgsql-9.3/bin/postgresql93-setup initdb

I found out

/usr/lib64/pgsql 

but this directory has only a bunch of '*.so' files.

How the hell do I run initdb for postgresql 9.2 on centos7?

Answer 1

Just installed the Postgresql 9.3 on Centos.

#cd /etc/init.d
#ls postgres*

and there is a posgresql-9.3 script

#./postgresql-9.3 

gives you the options to run with and one of them is initdb

Answer 2

您可以直接从postgres帐户运行它

#su - postgres -c pg_ctl initdb
