can't connect to local mysql server through socket '/var/run/mysqld/mysqld.sock'
# this saved my ass # first you must perform a graceful shutdown of the server from the command line rather than powering off the server shutdown -h now # an additional method for getting it back up again when you run into this problem is to move mysql.sock # to centos mv /var/lib/mysql/mysql.sock /var/lib/mysql/mysql.sock.bak # to ubuntu mv /var/run/mysqld/mysqld.sock /var/run/mysqld/mysqld.sock.bak # restart mysql service mysqld start
