Who are you running the script as?

marulitua commented 6 years ago

root user

jmrenouard commented 6 years ago

Hi

There is several issue about that. On Centos 7, systemctl is taking relay and log_error is no longer used.

journalctl -o cat -u mysql

journalctl -o cat -u mariadb

So, there is a lot of configuration settings.

Help needed on this subject.

jmrenouard commented 6 years ago

Hi @marulitua

Your error log is here: /var/log/mysql/error.log

Can you have a look at last version (1.7.12) ?

Are you sure you are running mysqltuner.pl as root (UNIX account) ?

Thnaks for your feedback.

jmrenouard commented 5 years ago
