Issue Starting MySQL Daemon
I have just come across the most random error I've seen my MySQL daemon spew out yet, everything was working fine, then all of a sudden it randomly crashed and it now outputting this when I start it up, not sure if it's because my 'my.cnf' file is minimal
Here's my 'my.cnf':
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under different user or group,
# customize your systemd unit file for mysqld according to the
# instructions in http://fedoraproject.org/wiki/Systemd
# Disabling symbolic-links is recommended to prevent assorted security risks
Here's the errors:
