MySQL -Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Posted on September 30, 2014

MySQL

By decaobr

I currenty have a LAMP, running on Ubuntu 14.04, yesterday everything was fine, but today my MYSQL is not working.

When i try to connect via

mysql -u root -p

I get the error: ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)

the Mysql.err file is completely empty, and have absolute no ideia about what to do.

My problem was running out of memory. Digital ocean has great instruction for adding swap memory for Ubuntu: https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04

This solved the issue and enabled me to restart the Mysql that otherwise would not start.

If you are creating a droplet from snapshot, then make sure to update the bind-address field with the new ip address.

$sudo nano /etc/mysql/my.cnf

Update the bind-address field with new ip address then run

$sudo service mysql start
