1安装linux
先设置ip
ifconfig eth0 192.168.15.150
连接 CRT 方法：https://blog.csdn.net/dudefu011/article/details/52121168
# 1配置ifcfg-eth0，静态ip，联网cd /etc/sysconfig/network-scripts
DEVICE=eth0HWADDR=*****
TYPE=Ethernet
UUID=5*******
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.15.150 #设置网卡IP地址 ****
NETMASK=255.255.255.0 #设置网卡掩码地址 ****
GATEWAY=192.168.15.2 #设置网卡对应的网络地址 ****
#2 cd /etc/sysconfig/ network
NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=192.168.15.2
#3 cd /etc/ resolv.conf
nameserver 114.114.114.114
nameserver 8.8.8.8
nameserver 8.8.4.4
替换后重启
配置防火墙，开启需要的端口
cd /etc/sysconfig/iptables# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter

COMMIT
替换后重启防火墙
查看防火墙状态：service iptables status
1) 重启后生效
开启： chkconfig iptables on
关闭： chkconfig iptables off
2) 即时生效，重启后失效
开启： service iptables start
关闭： service iptables stop
2.克隆服务器
vi /etc/sysconfig/network-scripts/ifcfg-eth0删除uuid，HWADDR,改ip
：wq保存退出
vi /etc/sysconfig/network
改HOSTNAME=contos2
rm –rf /udev/rules.d/70-persistent-net.rules
reboot
