CentOS 7 网卡设置

如何在CentOS 7 Minimal上配置静态IP地址

在这个简短的教程中,我将解释如何在CentOS 7 Minimal上配置静态IP地址

首先,需要编辑以太网的设置。让我们从编辑“/etc/sysconfig/network-scripts/ifcfg-enp0s3”文件开始:

vi /etc/sysconfig/network-scripts/ifcfg-enp0s3

文件内容如下:

HWADDR=08:00:27:6C:FF:91
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPADDR=192.168.0.88
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=enp0s3
UUID=ea68db6e-461e-427d-b9a8-bfcf6e1a4fc6
ONBOOT=yes

保存并退出。

现在,配置默认网关

vi /etc/sysconfig/network

并添加以下行:

NETWORKING=yes
HOSTNAME=centos7
GATEWAY=10.1.1.253

配置DNS服务器

vi /etc/resolv.conf

添加以下行:

nameserver 8.8.8.8
nameserver 8.8.4.4

现在重启你的网络或重启系统:

/etc/init.d/network restart

检查你的网络:

ip addr

输出示例:

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
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp0s3: <broadcast,multicast,up,lower_up> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 08:00:27:6c:ff:91 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.88/24 brd 192.168.0.255 scope global enp0s3
       valid_lft forever preferred_lft forever
    inet6 fe80::a00:27ff:fe6c:ff91/64 scope link
       valid_lft forever preferred_lft forever
