/etc/init.d/mysql start worked for me, but is there any reason mysql would suddenly stop? Is there a log to check for this or something?

Assuming the database is on the same server…

  1. Check that your database is actually running… ( sudo /etc/init.d/mysql start )

  2. Check that you have the correct info in the config.php file in your /wordpress/ directory… Ie: username = yourDBusername ( possibly “root”), password = yourDB password and host = localhost

Verify your DB my typing. mysql -u root -pYOURPASSWORD

Then type " Show databases;" ( Is your database listed? ) Type “exit” to quit.
