CentOS7.2设置静态IP

　　首先将源文件进行备份：

1 [zgw@localhost 桌面]$ sudo cp /etc/sysconfig/network-scripts/ifcfg-eno16777736 /etc/sysconfig/network-scripts/ifcfg-eno16777736.bak.zgw
2 [sudo] password for zgw:

　　编辑配置文件：

1 [zgw@localhost 桌面]$ sudo vi /etc/sysconfig/network-scripts/ifcfg-eno16777736

　　打开后如下所示：

 1 TYPE=Ethernet
 2 BOOTPROTO=dhcp
 3 DEFROUTE=yes
 4 PEERDNS=yes
 5 PEERROUTES=yes
 6 IPV4_FAILURE_FATAL=no
 7 IPV6INIT=yes
 8 IPV6_AUTOCONF=yes
 9 IPV6_DEFROUTE=yes
10 IPV6_PEERDNS=yes
11 IPV6_PEERROUTES=yes
12 IPV6_FAILURE_FATAL=no
13 NAME=eno16777736
14 UUID=00c21c9b-6e66-4541-8240-4b1bd2fdcf07
15 DEVICE=eno16777736
16 ONBOOT=no

　　修改后如下：

 1 TYPE=Ethernet
 2 BOOTPROTO=static
 3 DEFROUTE=yes
 4 PEERDNS=yes
 5 PEERROUTES=yes
 6 IPV4_FAILURE_FATAL=no
 7 IPV6INIT=no
 8 IPV6_AUTOCONF=yes
 9 IPV6_DEFROUTE=yes
10 IPV6_PEERDNS=yes
11 IPV6_PEERROUTES=yes
12 IPV6_FAILURE_FATAL=no
13 NAME=eno16777736
14 UUID=00c21c9b-6e66-4541-8240-4b1bd2fdcf07
15 DEVICE=eno16777736
16 ONBOOT=yes
17 IPADDR=192.168.89.11　　#IP
18 NATMASK=255.255.255.0　　#网关
19 GATEWAY=192.168.89.2　　#子网掩码
20 DNS1=1.2.4.8　　#DNS

　　常用的DNS地址：http://www.cnblogs.com/boyzgw/p/6651234.html

　　修改完成之后重启网卡服务：

1 [zgw@localhost 桌面]$ /etc/init.d/network restart
2 Restarting network (via systemctl): [ 确定 ]

　　查看并测试：
