Hola,

estoy teniendo problemas con MYSQL. Cada 1-2 días (nunca un tiempo fijo), MYSQL se me para y no me correr ninguna web (Wordpress) y me detecta el error de conexión en la web.

Para solucionar este error tengo que conectarme por ssh y hacer:

  1. Service mysql stop
  2. Service mysql start

¿Hay alguna forma para no tener que estar haciendo esto?

Dispongo de Ubuntu 18.04.3
Muchas gracias, un saludo.

Hi @administracion225549e6aab6,

It sounds like MySQL is being killed for some reason. The most common issue would be your Droplet is running out of Memory and killing MySQL so that it doesn’t crash down. Another issue might be something related to MySQL itself and nothing related to the droplet itself.

To check if it’s any of the mentioned you’ll need to go trough your log files. The first place I would recommend looking is the /var/log/messages. You’ll need to grep for either ‘kill’ or 'oom’ messages :

grep -i kill /var/log/messages
grep -i oom /var/log/messages

Alternatively, you can try and grep for mysql in the same log for more concrete output

grep -i mysql /var/log/messages

If you see the kill and oom signals, you’ll know that your droplet is actually running out of memory. So you’ll need to look into that direction.

If you don’t see anything, you’ll need to turn your attention to the MySQL Logs. Typically, the logs are located in ’/var/log/’. You’ll need to search for the error there. You can use 'grep error’ in the error.

As soon as you have the error you should be able to go further and resolve it.
