I don't know what exactly happen, but I can't start mysql over lamp controller. In console I can do it, but mysql is not started in fact. Here is my login file. Can some experienced look at it?

It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. To report this bug, see https://mariadb.com/kb/en/reporting-bugs We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.
