why does my mysql server stop?

Hello, @jbEel

You can examine the MySQL error_log file in order to track down any errors as well. You can check the exact location of the MySQL error log with these commands:

On Ubuntu droplet:

grep log_error /etc/mysql/mysql.conf.d/mysqld.cnf

The usual output will be:

log_error = /var/log/mysql/error.log

For CentOS droplets

grep log-error /etc/my.cnf

The usual output will be

log-error=/var/lib/mysql/droplet-hostname.err

You can then check the last 100 rows (or more if needed) logged in the error_log

tail -n 100 /var/log/mysql/error.log

You can look for any errors like:

InnoDB: Cannot allocate memory for the buffer pool

Hope this helps!

Hi, @jbEel To fully understand your issue with MySQL, I need to know some things first, in order to give a better and more accurate answer:

1. How many websites are pointed to this MySQL server?
2. What is the average number of database calls you have in an hour?
3. What is the configuration of your MySQL droplet? (CPU, RAM, region, etc)
4. What is the version of MySQL?
