How to show the last queries executed on MySQL?

Question

Is there any query/way to show the last queries executed on ALL servers?

Answer 1

You can enable a general query log for that sort of diagnostic. Generally you don't log all SELECT queries on a production server though, it's a performance killer.

Edit your MySQL config, e.g. /etc/mysql/my.cnf - look for, or add, a line like this

[mysqld]
log = /var/log/mysql/mysql.log

Restart mysql to pick up that change, now you can

tail -f /var/log/mysql/mysql.log

Hey presto, you can watch the queries as they come in.
