percona的安装涉及到percona server 和 percona cluster，这里主要讲解percona的cluster，我们主要用到的就是percona cluster。
一、安装
安装详情见官网：
https://www.percona.com/doc/percona-xtradb-cluster/5.6/index.html
二、配置
主要讲解我们使用到的配置。
percona1也就是第一台percona的my.cnf

我的环境是在Ubuntu14.04上使用repository安装的。
第一台percona启动的方法是：
service mysql bootstrap-pxc
重启：
service mysql restart-bootstrap
第二台percona启动的方法是：
service mysql start
重启：
service mysql restart
里面有些参数还可以进行优化。
