Centos7 配置靜態IP

1、編輯 ifcfg-eth0 文件。

 vi /etc/sysconfig/network-scripts/ifcfg-eth0  

2、修改如下內容

BOOTPROTO="static" #dhcp改爲static   
ONBOOT="yes" #開機啓用本配置  
IPADDR=192.168.163.100 #靜態IP   
NETMASK=255.255.255.0 #子網掩碼  

3、修改後效果

HWADDR="00:15:5D:07:F1:02"  
TYPE="Ethernet"  
BOOTPROTO="static" #dhcp改爲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" #開機啓用本配置  
IPADDR=192.168.163.100 #靜態IP  
NETMASK=255.255.255.0 #子網掩碼  

4、重啓下網絡服務

service network restart  

5、查看改動後的效果。
