Centos 7 静态IP设置
1、编辑 ifcfg-eth0 文件,vim 最小化安装时没有被安装,需要自行安装不描述。
# vim /etc/sysconfig/network-scripts/ifcfg-eth0
2、修改如下内容
BOOTPROTO=
"static"
#dhcp改为static
ONBOOT=
"yes"
#开机启用本配置
IPADDR=192.168.7.106
#静态IP
GATEWAY=192.168.7.1
#默认网关
NETMASK=255.255.255.0
#子网掩码
DNS1=192.168.7.1
#DNS 配置
3、修改后效果
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
HWADDR=
"00:15:5D:07:F1:02"
TYPE=
"Ethernet"
BOOTPROTO=
"static"
#dhcp改为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"
#开机启用本配置
IPADDR=192.168.7.106
#静态IP
GATEWAY=192.168.7.1
#默认网关
NETMASK=255.255.255.0
#子网掩码
DNS1=192.168.7.1
#DNS 配置
4、重启下网络服务
# service network restart
5、查看改动后的效果,Centois 7 不再使用 ifconfig 而是用 ip 命令查看网络信息。
# ip addr
