#修改启动脚本
vi /etc/init.d/mysql
basedir=/usr/local/pxc datadir=/data/pxc/mysql3306/data
4.启动，进行授权操作，对于第一个节点必须以特殊方式启动，如下：
/etc/init.d/mysql --help Usage: mysql {start|stop|restart|restart-bootstrap|reload|force-reload|status|bootstrap-pxc} [ MySQL (Percona XtraDB Cluster) options ]
第一个节点启动
/etc/init.d/mysql bootstrap-pxc
