Linux配置静态Ip

配置步骤

修改/etc/sysconfig/network-scripts/ifcfg-eth0（eth0为网卡文件名称，一般都为ens33）

[root@lzj ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
[root@lzj ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet               ---网卡类型
#UUID=30930cb0-2d69-4f81-9526-60bed337e547
BOOTPROTO=static            ----静态
NAME=eth0                   ----eth0为此配置文件名
DEVICE=eth0                 ----eth0为此文件配置文件名
IPADDR=192.168.135.145      -----ip地址
PREFIX=24                   -----相当于子网掩码                  
GATEWAY=192.168.135.2       -----网关
DNS1=192.168.135.2          -----DNS地址
ONBOOT=yes
[root@lzj ~]# 

重启网卡

[root@lzj ~]# systemctl restart network
[root@lzj ~]# 

验证

[root@lzj ~]# ifconfig
