Optimizing MySQL Configuration - Percona

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]
