Hallo,
habe vorhin auf meinen Server mit apt-get upgrade geupdated, seitdem startet mysql nicht mehr.

Im syslog steht folgendes:

Aug 4 15:24:58 server mysqld_safe[11121]: started
Aug 4 15:24:58 server mysqld[11124]: mysqld got signal 11;
Aug 4 15:24:58 server mysqld[11124]: This could be because you hit a bug. It is also possible that this binary

Aug 4 15:24:58 server mysqld[11124]: and this may fail.

Die Datei mysqld.sock existiert in der Tat nicht (aber die Dait wird doch vom init.d Skript erstellt!?). Die Rechte vom mysqld Verzeichniss stimmen und auch in der /etc/mysql/my.cnf sind die richtigen Pfade angegeben.

Wäre super wenn mir jemand weiterhelfen kann.

Gruß,
Till
