Comment 5 for bug 1260283

@Yan,

It works but I noticed this:

MySQL [(none)]> set global wsrep_provider='none';
Query OK, 0 rows affected (2.02 sec)

MySQL [(none)]> set global wsrep_provider='/usr/lib64/libgalera_smm.so';

It fails with:

The problem is that, without ability to set listen_addr before it
actually listens, it ends up listening on default addr:port.
