serverA 192.168.1.30 3.10.0-229.el7.x86_64 CentOS Linux release 7.1.1503 (Core)

二、修改网卡名为eth0
1、备份配置
cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.bak

2、修改配置
diff /boot/grub2/grub.cfg /boot/grub2/grub.cfg.bak
88c88
<     linux16 /vmlinuz-3.10.0-229.el7.x86_64 root=UUID=5120ba17-c4a9-403a-b9df-b2fa09957e14 ro crashkernel=auto rhgb quiet LANG=en_US.UTF-8 net.ifnames=0 biosdevname=0

3、改配置名字
mv /etc/sysconfig/network-scripts/ifcfg-eno16777736 /etc/sysconfig/network-scripts/ifcfg-eth0

Restarting network (via systemctl):                        [  OK  ]

6、重启机器
reboot

    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:d2:b2:51 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.30/24 brd 192.168.1.255 scope global eth0
       valid_lft forever preferred_lft forever
