PXC安装
第一节点
传入percona-release-0.1-6.noarch.rpm 文件
[root@localhost ~]# yum install -y percona-release-0.1-6.noarch.rpm
[root@localhost ~]# yum install Percona-XtraDB-Cluster-57
传入my.cnf 文件
克隆两个虚拟机
[root@localhost ~]# mv my.cnf /etc/my.cnf
[root@localhost ~]# vi /etc/my.cnf

修改 里面的ip
mkdir -p /mysqldb/db_pxc/
[root@localhost db_pxc]# systemctl start mysql@bootstarp.service
[root@localhost db_pxc]# less mysql_error.log|grep temp (查看临时密码）
[root@localhost db_pxc]# mysql -uroot -p（临时密码）-S /mysqdb/db_pxc/mysql.sock
