Hey All, I'm semi new to linux and this group and I'm hoping you might be able to help me out a little.

I have a vanilla installation of RHEL 7 and I'm trying to setup a two node MariaDB Galera Cluster but I getting the following error message when I try to start the service:

[root@db2 ~]# /usr/libexec/mysqld --wsrep-new-cluster --user=root &

The below are the commands and file edits I've done:

Can anymore help or maybe point me into into the right direction

Then please don't be offended if I ask you a semi-dumb suggestion.
Why don't you wrap this path
"/usr/lib64/galera/libgalera_smm.so"
In quotes and see if that forces the mysqld to parse it.
Or it could be something as simple as you need to put a spaces between "provider" and "=" and "/usr".

Of course if all that fails, you might try RTFM

I've never put a MariaDB on a cluster, but when I had to load up an Oracle 11.x DB on one, I spent a week reading the one from Oracle before I started.

Maybe libgalera_smm.so is under directory "/usr/lib/" not "/usr/lib64/"
You should be able to find it with a "locate libgalera_smm.so"
