Percona Server my.cnf Setup

Percona Server（延伸自 MySQL）預設是沒有給 my.cnf 在 /etc/mysql 裡頭的。若有需要的話，可以依照主機資源狀況，從 /usr/share/mysql 拿一份過去用。（for Percona 5.5.24, Ubuntu 12.04）

參考文件：http://superuser.com/questions/426844/where-from-to-install-my-cnf-for-percona-db

其建議的資源參考值（只計算 Percona 本身所使用到的記憶體）：

1. my-innodb-heavy-4G.cnf (apporpriate for 4GB+ memory installation with InnoDB and heavy queries)
2. my-huge.cnf (appropriate for 2GB+ memory installation dedicated MySQL)
3. my-large.cnf (appropriate for 512MB memory installations dedicated MySQL server)
4. my-medium.cnf (appropriate for 128MB memory installations, small DB along with web server)
5. my-small.cnf (appropriate for 64MB memory installation, sporadic use of the database)
