Can't start mysql on Linux - Can't access / var / log / mysqld.log:

I am trying to start mysql on Red Hat 7. I uninstalled maria db and installed mysql following instructions:

http://dev.mysql.com/doc/mysql-repo-excerpt/5.6/en/linux-installation-yum-repo.html#yum-repo-setup

    > service mysql start
Redirecting to /bin/systemctl start  mysql.service
screen hangs here...

^C


[root@abc mysql]# service mysql status

OK let's take a look at / var / log / mysql

[root@abc ~]# ll /var/log | grep mysql  
-rw-r-----. 1 mysql  mysql        0 May 12 16:01 mysqld.log

      

        
        
        
      

    

I am checking on another system, the permissions are the same as above. OK I will try to fix the file ...

[root@abc ~]# chmod 777 /var/log/mysqld.log

      

        
        
        
      

    

Now restart.

[root@abc ~]# service mysql start

      

        
        
        
      

    

same errors as above and I am losing my chmod ...

ll / var / log | grep mysql -rw -p -----. 1 mysql mysql 0 May 12 16:01 mysqld.log

Selinux is in permissive mode.
