**两台主机都一样的部署**

关闭防火墙

[root@node2 ~]# systemctl stop firewalld
[root@node2 ~]# systemctl disable firewalld

关闭selinux

sed '/SELINUX/s/enforcing/disabled/g /etc/sysconfig/selinux'

设置时间同步

[root@node2 ~]# systemctl start chronyd
[root@node2 ~]# systemctl enable chronyd

修改hosts

[root@node1 ~]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.216.51 node1
