multiple err logs?

I've just installed MariaDB-Galera 5.5.29 on CentOS 6.4. With the standard my.cnf in place, when I start the server with "service MySQL start" two err files are created, maria1.err and maria1.towxchange.net.err. The first seems to have a subset of the messages in the second, but the timestamps are different and the timestamps in the first file seem to be incorrect. The full hostname is maria1.towxchange.net, so I'm confused as to where maria1.err is coming from. Any ideas?

Hi,

I've just installed MariaDB-Galera 5.5.29 on fresh CentOS 6.4, and I only have one error log, <full host name>.err. I did the following:

  • create a new CentOS 6.4 VM;
  • configure yum repo for MariaDB 5.5;
  • run 
sudo yum install MariaDB-Galera-server MariaDB-client
  • check that there are no logs in /var/lib/mysql/
  • run 
sudo /etc/init.d/mysql start
  • check that there is only one log /var/lib/mysql/localhost.localdomain.err

Did you do it the same way? If so, where is the additional log file located, and what is it contents? Could it be that you had a MariaDB / MySQL installation before, and this log remains from that time?
