Installing A Web, Email And MySQL Database Cluster (Mirror) On Ubuntu 14.04 With ISPConfig 3

I am using this site https://www.howtoforge.com/installi...tabase-cluster-on-debian-5.0-with-ispconfig-3 how to a guide, but I have problems with the settings when configure mysql database in both servers. Receive the followings Errors:
==> mysql/error.log <==
InnoDB: using the same InnoDB data or log files.
InnoDB: Unable to lock ./ibdata1, error: 11
InnoDB: Check that you do not already have another mysqld process

160407 18:41:30 InnoDB: to what it was, and remove the new ibdata files InnoDB created
160407 18:41:30 InnoDB: in this failed attempt. InnoDB only wrote those files full of
160407 18:41:30 InnoDB: zeros, but did not yet use them in any way. But be careful: do not

Hi,

Had a similar issue using ubuntu 12.04/14.04 and mysql. Did you ever find a solution?
