Unable to start postgresql service on CentOS 7

Unable to start postgresql-9.5 on CentOS 7.

I followed this page - https://wiki.postgresql.org/wiki/YUM_Installation - for installing the database server on CentOS.

I tried the same after setting setenforce 0, and that did not help either.

I am doing all operations as root.

systemctl start postgresql-9.5.service Job for postgresql-9.5.service failed because the control process exited with error  code. See "systemctl status postgresql-9.5.service" and "journalctl -xe" for details. 

And here is what I get for status -

Redirecting to /bin/systemctl status  postgresql-9.5.service ● postgresql-9.5.service - PostgreSQL 9.5 database server    Loaded: loaded (/usr/lib/systemd/system/postgresql-9.5.service; enabled; vendor preset: disabled)    Active: failed (Result: exit-code) since Thu 2016-02-18 15:20:30 EST; 2min 28s ago   Process: 15041 ExecStartPre=/usr/pgsql-9.5/bin/postgresql95-check-db-dir ${PGDATA} (code=exited, status=1/FAILURE)  Feb 18 15:20:30 myserver systemd[1]: Starting PostgreSQL 9.5 database server... Feb 18 15:20:30 myserver systemd[1]: postgresql-9.5.service: control process exited, code=exited status=1 Feb 18 15:20:30 myserver systemd[1]: Failed to start PostgreSQL 9.5 database server. Feb 18 15:20:30 myserver systemd[1]: Unit postgresql-9.5.service entered failed state. Feb 18 15:20:30 myserver systemd[1]: postgresql-9.5.service failed. 

And the contents of the different conf files are as follows -

[root@myserver /]# cat /etc/ld.so.conf.d/postgresql-pgdg-libs.conf /usr/pgsql-9.5/lib/  [root@myserver /]# cat /usr/lib/tmpfiles.d/postgresql-9.5.conf d /var/run/postgresql 0755 postgres postgres -  [root@myserver /]# cat /usr/pgsql-9.5/share/postgresql-9.5-libs.conf /usr/pgsql-9.5/lib/  [root@myserver /]# cat /etc/alternatives/pgsql-ld-conf /usr/pgsql-9.5/lib/  [root@myserver /]# cat /var/lib/alternatives/pgsql-ld-conf auto /etc/ld.so.conf.d/postgresql-pgdg-libs.conf  /usr/pgsql-9.5/share/postgresql-9.5-libs.conf 950 

Googled for the error that I am seeing. A number of folks have seen the same error, and the underlying cause is different in each case. Reading through those posts, it is not clear that I am seeing any of the already reported causes.

Make sure you have installed all packages correctly and updated yum repository sections [base] and [updates] before installation as it mentioned in the guide . We have CentOS 7 with PostgreSQL 9.5 and it works perfectly fine with following steps:

vi /etc/yum.repos.d/CentOS-Base.repo yum localinstall http://yum.postgresql.org/9.5/redhat/rhel-7-x86_64/pgdg-centos95-9.5-2.noarch.rpm yum list postgres* yum install -y postgresql95-server.x86_64 postgresql95-contrib.x86_64 postgresql95-libs.x86_64  /usr/pgsql-9.5/bin/postgresql95-setup initdb systemctl enable postgresql-9.5.service systemctl start postgresql-9.5.service  

and finally, systemctl status postgresql-9.5.service should show you something like this:

postgresql-9.5.service - PostgreSQL 9.5 database server    Loaded: loaded (/usr/lib/systemd/system/postgresql-9.5.service; enabled)    Active: active (running) since Fri 2016-02-19 00:01:13 UTC; 6min ago   Process: 10809 ExecStart=/usr/pgsql-9.5/bin/pg_ctl start -D ${PGDATA} -s -w -t 300 (code=exited, status=0/SUCCESS)   Process: 10802 ExecStartPre=/usr/pgsql-9.5/bin/postgresql95-check-db-dir ${PGDATA} (code=exited, status=0/SUCCESS)  Main PID: 10811 (postgres)    CGroup: /system.slice/postgresql-9.5.service            ├─10811 /usr/pgsql-9.5/bin/postgres -D /var/lib/pgsql/9.5/data            ├─10812 postgres: logger process               ├─10814 postgres: checkpointer process               ├─10815 postgres: writer process               ├─10816 postgres: wal writer process               ├─10817 postgres: autovacuum launcher process               └─10818 postgres: stats collector process
