Centos 7 / Mysql – Too many open files error

By Server Admin No Comments

Even after raising the limit in ‘/etc/security/limits.conf’ and restarting the system, I was getting the ‘Too many open files’ error.

The solution that worked –

edit /usr/lib/systemd/system/mysqld.service and add

LimitNOFILE=infinity
LimitMEMLOCK=infinity

run systemctl daemon-reload and systemctl restart mysql.service
