2021-05-27:Centos7修改静态IP

1.安装vim编辑器

yum install vim-enhanced

2.打开网卡配置文件

vim /etc/sysconfig/network-scripts/ifcfg-ens33

3.配置网卡前确认自己的网段

3.配置网卡文件

PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static" #静态获取IP地址
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="44e8da0d-e8c0-4c49-b410-2e479d79c0e6"
DEVICE="ens33"
ONBOOT="yes" #默认激活网卡
IPADDR="192.168.72.147" #配置静态IP
NETMASK=255.255.255.0   #子网
GATEWAY=192.168.72.2    #网关，一般默认是2
DNS1=8.8.8.8            #DNS，没有他分析不了域名，上不去网
DNS2=114.114.114.114    #备用

4.重启网卡,ifconfig查看IP

systemctl restart network

ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.72.147  netmask 255.255.255.0  broadcast 192.168.72.255
        inet6 fe80::e5e1:3c75:14c:8ff5  prefixlen 64  scopeid 0x20<link>
