Folks

I'm having problems installing Mariadb in Centos 7.


Here's what I did:

0)  Become root
1)  Make sure that mariadb and mysql are NOT installed.
2)  Delete residual libs
          rm -rf /var/lib/mysq*
3)  yum install -y mariadb-server
     installed mariadb-5.5.50-1.el7_2.x86_64 from the Centos 
'updates' repository
4)  systemctl start mariadb
5)  systemctl status mariadb

All works well until step 5, where I get the result:



# systemctl status mariadb
? mariadb.service - MariaDB database server
    Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; 
vendor preset: disabled)

My environment is a Centos 7 installation running as a VM inside 
Vmware, and is not a production system.  It is updated nightly.

When I examined the files alluded to,

   /var/log/mysqld.log
  does not exist
but
   /var/log/mariadb/mariadb.log
  exists and is empty.

Adivce would be appreciated

Thanks

David
