linux如何正确设置静态ip

如果是新安装的CentOS7的用户,刚开始应该是没网的,ifconfig命令在CentOS7已经被淘汰了。

1.使用ip addr 即查看分配网卡情况。

2.激活网卡

[root@localhost ~]# cd /etc/sysconfig/network-scripts
[root@localhost network-scripts]# ls
[root@localhost network-scripts]# vi ifcfg-eno16777736
将ONBOOT=no改为ONBOOT=yes,输入esc :wq保存退出

3.重启网卡

service network restart

4.关闭防火墙

systemctl stop firewalld.service

开始配置静态ip

如果虚拟机安装。网络模式选择桥接（相当于是在局域网中新增加一台电脑）

1.设置ifcfg-eno16777736:

[root@localhost /]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# ls
ifcfg-eno16777736  ifdown-eth   ifdown-isdn    ifdown-sit       ifup          ifup-ib    ifup-plip   ifup-routes    ifup-tunnel        network-functions-ipv6
ifcfg-lo           ifdown-ib    ifdown-post    ifdown-Team      ifup-aliases  ifup-ippp  ifup-plusb  ifup-sit       ifup-wireless
ifdown             ifdown-ippp  ifdown-ppp     ifdown-TeamPort  ifup-bnep     ifup-ipv6  ifup-post   ifup-Team      init.ipv6-global
ifdown-bnep        ifdown-ipv6  ifdown-routes  ifdown-tunnel    ifup-eth      ifup-isdn  ifup-ppp    ifup-TeamPort  network-functions

[root@localhost network-scripts]# vi ifcfg-eno16777736

-----------------------修改的属性-----------------------
ONBOOT=yes
#静态
BOOTPROTO=static

------------------------增加的属性-----------------------
#ip地址
IPADDR=10.1.1.20

#网关
GATEWAY=10.1.1.1

#子网掩码
NETMARK=255.255.255.0
DNS1=10.1.1.1

2.重启网络配置

service network restart
