Info

Avoid Basic Mistakes • Setting variables in wrong config file – /etc/mysql/my.cnf instead of /etc/my.cnf • These depend on Linux Distro, Beware • Duplicating Options – Last option will override previously set • Not knowing Synonyms – table_cache is same as table_open_cache • Using wrong section for option – Server reads [mysqld], client [mysql] www.percona.com
Config Management Practices • Keep Config Files in Sync on different servers – Out of Sync config files is frequent cause of mistakes and confusion • Keep Record of Changes – Config files under version control is great www.percona.com
