[root@root123 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0

 

2, the following modifications

1 BOOTPROTO = " static " #dhcp changed to static 
 2 ONBOOT = " yes " # boot configuration to enable this
 3 IPADDR = 192.168 . 197.131 # static IP
 4 GATEWAY = 192.168 . 197.2 # Default Gateway
 5 NETMASK = 255.255 . 255.0 # subnet mask code
 . 6 the DNS1 = 192.168 . 197.2 #DNS configuration

 

3, the effect of the modified

[root@root123 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
HWADDR="00:15:5D:07:F1:02"
TYPE="Ethernet"
BOOTPROTO="static" #dhcp改为static 
DEFROUTE="yes"
PEERDNS="yes"
PEERROUTES="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_PEERDNS="yes"
IPV6_PEERROUTES="yes"
IPV6_FAILURE_FATAL="no"
NAME="eth0"
UUID="bb3a302d-dc46-461a-881e-d46cafd0eb71"
ONBOOT="yes" #开机启用本配置
IPADDR=192.168.197.131#静态IP
GATEWAY=192.168.197.2 # default gateway
NETMASK = 255.255 . 255.0 # subnet mask 
DNS1 = 192.168 . 197.2 #DNS Configuration

 

4, under the Network Service Restart

[root@root123 ~]# service network restart

  

5, after the effect of view changes, Centois 7 but no longer use ifconfig ip command to view network information.

[root@root123 ~]# ip addr
1
