Lately, I have been getting many warnings on my MySQL Server, getting into some crashes and restarting.

I looked at the status of MySQL and found the logs stating,

mysql.service: Main process exited, code=killed, status=9/KILL

To analyse this correctly, I looked at the MySQL logs at /var/log/mysql directory.
However, log rotation was enabled, compressing the previous log files.

To read all of these files means I will have to extract each one and then open them.

But there is a better way, using the command zcat

To use this command, you need to pass on the path of the gzip file as the argument.

zcat /var/log/mysql/error.log.1.gz
