percona的安裝涉及到percona server 和 percona cluster，這裡主要講解percona的cluster，我們主要用到的就是percona cluster。
一、安裝
安裝詳情見官網：
二、配置
主要講解我們使用到的配置。
percona1也就是第一台percona的my.cnf

我的環境是在ubuntu14.04上使用repository安裝的。
第一台percona啟動的方法是：
service mysql bootstrap-pxc
重啟：service mysql restart-bootstrap
第二台percona啟動的方法是：
service mysql start
重啟：service mysql restart
裡面有些引數還可以進行優化。
