MySQL not starting or can’t login ? Mac OS X

Filed under: Uncategorized — majestrooo @ 10:26 f m

This happened to me recently as I switched to a different network. Everything was working and I had not changed any setting whatsoever. But I failed to login to MySQL and got errors like

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)


STOPPING server from pid file /usr/local/mysql/data/

I was seriously considering reinstalling but…I *knew* it was all running good before so there must’ve been something else.

The problem was that mysql was configured with ‘localhost’ (fine) but for some reason my hostname was not ‘localhost’ on the new network, instead I had the network’s address.

In Terminal

$ hostname



$ sudo hostname localhost <or whatever you set up with, e.g. before>

Restart mysql

$ sudo launchctl unload -w /Library/LaunchDaemons/com.mysql.mysqld.plist

$ sudo launchctl load -w /Library/LaunchDaemons/com.mysql.mysqld.plist

Voila it worked after that!

$ mysql -u root [-p]

  3. This is a great exercise to get your blood pumping and work your calves.

    I say may- because as in all extreme sports while there is certainly a measurable
    amount of skill required there is also a great deal of mental training
    that goes with it.

  6. Right now it appears like Expression Engine is the best blogging platform out there right now.
    (from what I’ve read) Is that what you are using on your blog?
