下载：
登录官方网站 ：https://www.percona.com/
下载pxc 组件rpm包
注：也可以选择下面一个个安装，这里我选的是官网打好包的文件
wget https://www.percona.com/downloads/Percona-XtraDB-Cluster-LATEST/Percona-XtraDB-Cluster-5.7.19-29.22-3/binary/redhat/6/x86_64/Percona-XtraDB-Cluster-5.7.19-29.22-r374-el6-x86_64-bundle.tar
下载xtrabackup
注意：版本2.4是pxc5.7用的，版本2.3以下（包含2.3）不适合pxc5.7.所以要选

Initializing MySQL database: [ OK ]
Starting MySQL (Percona XtraDB Cluster).....................................The server quit without updating PID file (/opt/mysql/logs/mysql.pid). [FAILED]
MySQL (Percona XtraDB Cluster) server startup failed! [FAILED]
解决方法：检查日志，一般是网络 不通，地址写的不对，初始化的时候datadir不是空的文件夹，或者datadir 目录不对；
pxc验证:
在pxc0创建库并插入数据，在pxc02 pxc03查看
mysql> create database pxc01; Query OK, 1 row affected (0.01 sec) mysql> use pxc01; Database changed mysql> create table t1(id int,name varchar(20),sex char(1)); Query OK, 0 rows affected (0.06 sec) mysql> insert into t1 values(26,"world","M"); ERROR 1105 (HY000): Percona-XtraDB-Cluster prohibits use of DML command on a table (pxc01.t1) without an explicit primary key with pxc_strict_mode = ENFORCING or MASTER //验证了PXC的特性，每个表都要有主键 mysql> alter table t1 add primary key (id); Query OK, 0 rows affected (0.07 sec) Records: 0 Duplicates: 0 Warnings: 0 mysql> insert into t1 values(26,"world","M"); Query OK, 1 row affected (0.03 sec)
在pxc02-03查看数据
然后分别去验证，如果都能写入，在集群各节点都可以查看，日志里没有异常错误，说明PXC 搭建完成；
