DEFROUTE=yes
NAME=ens3
DEVICE=ens3
ONBOOT=yes
IPADDR=172.17.10.53
NETMASK=255.255.255.128
GATEWAY=172.17.10.1
DNS1=202.96.128.86
DNS2=114.114.114.114

2.设置主机名

hostnamectl set-hostname computer01

3.修改hosts

echo '172.17.10.52 controller' >> /etc/hosts
echo '172.17.10.53 computer01' >> /etc/hosts
echo '172.17.10.54 computer02' >> /etc/hosts

4.修改yum仓库

cd /etc/yum.repos.d
mkdir backup
mv * backup
