Centos7 下静态IP设置

1、进入network-scripts目录并且查看该目录下存在的ifcfg-xx文件

cd /etc/sysconfig/network-scripts#xx为用户自己目录下的ifcfg-xx 文件vim /etc/sysconfig/network-scripts/ifcfg-xx

2.修改如下配置内容

BOOTPROTO=static #将dncp改为staticONBOOT="yes"  #开机时启用本配置IPADDR=192.168.13.131 #静态ipGATEWAY=192.168.13.2 #默认网关NETMASK=255.255.255.0#子网掩码DNS1=192.168.13.2 #DNS配置

3.修改后ifcfg-ens33 文件内容如下

TYPE="Ethernet"DEFROUTE=yesIPV4_FAILURE_FATAL="no"IPV6INIT="yes"IPV6_AUTOCONF="yes"IPV6_DEFROUTE="yes"IPV6_FAILURE_FATAL="no"IPV6_ADDR_GEN_MODE="stable-privacy"NAME="ens33"UUID="c40937f7-ebf8-41e8-8541-d79fc3dff61e"DEVICE="ens33"PREFIX=24IPV6_PEERDNS=yesIPV6_PEERROUTES=yesBOOTPROTO=static #将dncp改为staticONBOOT="yes" #开机时启用本配置DNS1=192.168.13.2 #DNS配置IPADDR=192.168.13.131 #静态ipNETMASK=255.255.255.0#子网掩码GATEWAY=192.168.13.2 #默认网关

4.重启网络服务

service network restart

5.查看改动后的效果，使用ifconfig或者ip addr

 ifconfig #输出结果如下 ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500        inet 192.168.13.131  netmask 255.255.255.0  broadcast 192.168.13.255        inet6 fe80::c43e:1e6b:69b:5ba8  prefixlen 64  scopeid 0x20<link>        ether 00:0c:29:9e:22:eb  txqueuelen 1000  (Ethernet)        RX packets 6763  bytes 520694 (508.4 KiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 2700  bytes 541708 (529.0 KiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536        inet 127.0.0.1  netmask 255.0.0.0        inet6 ::1  prefixlen 128  scopeid 0x10<host>        loop  txqueuelen 1  (Local Loopback)        RX packets 0  bytes 0 (0.0 B)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 0  bytes 0 (0.0 B)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0virbr0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500        inet 192.168.122.1  netmask 255.255.255.0  broadcast 192.168.122.255        ether 52:54:00:96:18:0e  txqueuelen 1000  (Ethernet)        RX packets 0  bytes 0 (0.0 B)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 0  bytes 0 (0.0 B)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
