本学习主要针对 Centos 7.0.1406 版本进行学习整理!
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
# 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
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
# ]# 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
# 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
-
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
-
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
-
inet 127.0.0.1/8 scope host lo
-

-
inet6 ::1/128 scope host
-
valid_lft forever preferred_lft forever
-
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
-

-

-

-
