将整个虚拟机再克隆两个

#####修改主机名
shell>hostname c2
shell>vi /etc/sysconfig/network
hostname=c2
#####修改ip地址
shell>vi /etc/sysconfig/network-script/ifcfg-eth0
shell>service network restart
#####修改mysql配置文件

selinux 没关和xtrabackup版本太低 日常启动关闭
#/etc/init.d/mysql stop
全部节点关闭后重启
第一个节点启动的节点（如果集群全部关闭，第一个起动也需要用这样的形式）
#/etc/init.d/mysql bootstrap-pxc
其它节点
#/etc/init.d/mysql start
备注：
如集群是不是所有的节点都关闭不用使#/etc/init.d/mysql bootstrap-pxc 启动。都可以用
#/etc/init.d/mysql start
启动。到此，关于“PXC5.7的安装步骤”的学习就结束了，希望能够解决大家的疑惑。理论与实践的搭配能更好的帮助大家学习，快去试试吧！若想继续学习更多相关知识，请继续关注开发云网站，小编会继续努力为大家带来更多实用的文章！
