MySQL Daemon failed to start.

Recently I started working on a very basic Drupal website for a friend, by doing that it sadly seems that it has overloaded mysql. Can it really be that 1 Drupal install on a 512mb droplet eats up all the swap?

Anyway, I’m running CentOS with NginX, php-fpm, mysqld.

I’ve checked the mysqld.log and every time I try “service mysqld restart” this is what shows up in the log:

---

131128 22:05:57 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

To my knowledge, it seems that it can’t load into swap or something similar to that, but I could be wrong.

Anyone know how I can solve this?
