1.1 问题
环境准备
安装软件包
1.2 方案
准备3台虚拟主机，配置ip地址和主机名。具体如图-1所示：（不需要安装任何MySQL服务软件）
图-1
1.3 步骤
实现此案例需要按照如下步骤进行。
步骤一：环境准备
配置主机名与ip地址绑定
配置服务器192.168.4.71
]# vim /etc/hosts
192.168.4.71 pxcnode71
192.168.4.72 pxcnode72
192.168.4.73 pxcnode73
:wq
]#hostname pxcnode71
配置服务器192.168.4.72
]# vim /etc/hosts
192.168.4.71 pxcnode71
192.168.4.72 pxcnode72
192.168.4.73 pxcnode73
:wq
]#hostname pxcnode72
配置服务器192.168.4.73
]# vim /etc/hosts
192.168.4.71 pxcnode71
192.168.4.72 pxcnode72
192.168.4.73 pxcnode73
:wq
]#hostname pxcnode73
在任意一台服务器上ping 对方的主机名，ping通为配置成功。

步骤二：安装软件包
1）在192.168.4.71 服务器安装软件包
软件包之间有依赖注意软件包安装顺序
]# rpm -ivh libev-4.15-1.el6.rf.x86_64.rpm //安装依赖
]# yum -y install percona-xtrabackup-24-2.4.13-1.el7.x86_64.rpm
]# rpm -ivh qpress-1.1-14.11.x86_64.rpm //安装依赖
]# tar -xvf Percona-XtraDB-Cluster-5.7.25-31.35-r463-el7-x86_64-bundle.tar
]# yum -y install Percona-XtraDB-Cluster-*.rpm
2）在192.168.4.72 服务器安装软件包
]# rpm -ivh libev-4.15-1.el6.rf.x86_64.rpm //安装依赖
]# yum -y install percona-xtrabackup-24-2.4.13-1.el7.x86_64.rpm
]# rpm -ivh qpress-1.1-14.11.x86_64.rpm //安装依赖
]# tar -xvf Percona-XtraDB-Cluster-5.7.25-31.35-r463-el7-x86_64-bundle.tar
]# yum -y install Percona-XtraDB-Cluster-*.rpm
3）在192.168.4.73 服务器安装软件包
]# rpm -ivh libev-4.15-1.el6.rf.x86_64.rpm //安装依赖
]# yum -y install percona-xtrabackup-24-2.4.13-1.el7.x86_64.rpm
]# rpm -ivh qpress-1.1-14.11.x86_64.rpm //安装依赖
]# tar -xvf Percona-XtraDB-Cluster-5.7.25-31.35-r463-el7-x86_64-bundle.tar
