Have just installed Percona server 5.6 and have not yet changed any settings in my.cnf, but when i try to restart or stop the server this error is returned
root@dyntest-amd-6000-8gb ~ # service mysql restart
[FAIL] Stopping MySQL (Percona Server): mysqld failed!
[ ok ] Starting MySQL (Percona Server) database server: mysqld already running.
There are no errors in the log (both files are empty)
