MySQL on Ubuntu Keeps Crashing

I’ve got an Ubuntu 12.x Droplet running, and for some reason MySQL keeps crashing to where I need to go in and restart the process (‘sudo service mysql restart’).

I’m not even sure how to start debugging this - could anyone give me some guidance on how to start? My MySQL logs are empty in /var/log/

Finally this helped, none of other solution did any change (add swap, monitor for banned iP’s, upgrade droplet):

## Edit /etc/my.cnf, and add the following line under the [mysqld] heading.

Then restart: `$  service mysql restart`

This is a pretty common issue with WordPress, certainly not the fault of the DO preconfigured instance as I’ve experienced the same spinning up my own DO instances as well as back when I used to use AWS EC2. Moving up to an instance with more memory may help temporarily, but you’ll likely still eventually come face to face with this issue.

My sites will typically work flawlessly for several months until eventually they start to become plagued with MySQL crashes. My solution almost always ends up being spinning up a new instance and migrating over where the 2-4 month cycle just repeats itself. I’ve yet to be able to pin down the root cause or a solution.
