Question
Ideal configuration for MySQL on the smallest droplet?
- Posted on June 9, 2014
Asked by garrettgardner
I am a web dev that has made several droplets for clients that have extremely low-traffic Wordpress sites. I generally recommend the smallest droplet with Ubuntu 12.04 and the LAMP stack.
However, the MySQL process on each of these droplets will periodically crash, causing the site to go down until it is manually restarted. I believe the problem is due to a loss of memory. I know that one solution would simply be to increase the size of the droplet, but these sites are extremely low-traffic (handful of page views per day) and this is still occurring. Is there some ideal configuration that may prevent this, or some known issue with the default MySQL configuration on the smallest droplet that has a fix?
Thank you!

One thing you can do to help with running out of memory on the smallest droplet is to add a swap file. This way on the rare occasions when your memory consumption spikes, it will use the swap rather than crashing. See: <br> <br>https://www.digitalocean.com/community/articles/how-to-add-swap-on-ubuntu-12-04 <br> <br>On Ubuntu, you might also want to take a look at the file: <br> <br>/usr/share/doc/mysql-server-5.5/examples/my-small.cnf <br> <br>It contains some configuration optimizations for using MySQL on systems with little memory. You can replace /etc/mysql/my.cnf with it, or just tweak certain options as you see fit.
