环境介绍：

pxc三个节点:

192.168.1.6 test06

192.168.1.7 test07

192.168.1.8 test08

操作系统版本:CentOS release 6.8 (Final)

在安装pxc之前需要安装如下基础软件包:

# yum install -y socat perl-IO-Socket-SSL.noarch perl-DBD-MySQL.x86_64 perl-Time-HiRes openssl openssl-devel

关闭防火墙:

# service iptables stop

yum方式安装:

[root@test06 /]# yum install http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm
