MySQL Job failed to start

Question

I\'m on Kubuntu 12.04, and after installing mysql via an apt-get (mysql ver: 5.5.35), i\'m trying to start mysql service, but I got this error:

sudo servi

Answer 1

Reinstallation will works because it will reset all the value to default. It is better to find what the real culprits (my.cnf editing mistake does happens, e.g. bad/outdated parameter suggestion during mysql tuning.)

Here is the mysql diagnosis if you suspect some value is wrong inside my.cnf : Run the mysqld to show you the results.

sudo -u mysql  mysqld 

Afterwards, fix all the my.cnf key error that pop out from the screen until mysqld startup successfully.

Then restart it using

sudo service mysql restart
