CentOS7配置静态IP - Githubissues

查看MAC地址

[root@c1 ~]# 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
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:6f:9a:fa brd ff:ff:ff:ff:ff:ff
    inet 192.168.64.145/24 brd 192.168.64.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:fe6f:9afa/64 scope link 
       valid_lft forever preferred_lft forever

其中link/ether 00:0c:29:6f:9a:fa就是物理网卡地址编辑/etc/sysconfig/network-scripts/ifcfg-eth0

TYPE=Ethernet
#BOOTPROTO=dhcp
BOOTPROTO=static
HWADDR=00:0c:29:6f:9a:fa

重启系统安装ifconfig

sudo yum install net-tools
[root@c1 ~]# ifconfig
