# 1.首先安装一台centos7(4G+40G+NAT+最小安装+管理员密码设置为root),并复制三份,分别重命名为node01,node02,node03.
# 2。其次分别对 node01,node02,node03 三台主机进行如下配置
# 将网卡配置文件最后一行的 ONBOOT=no 修改为 ONBOOT=yes
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33
ONBOOT=yes
[root@localhost ~]# service network restart
Restarting network (via systemctl): [ OK ]
[root@localhost ~]# yum -y install net-tools wget vim zip unzip lrzsz

# 3.根据ifcfg查出的网卡ens-33的IP地址信息分别配置三个XShell连接三台主机(node01,node02,node03)
# 此处为 node01:192.168.150.128;node02:192.168.150.129;node03:192.168.150.130;
