How to solve the problem that device eth0 does not exist under centos

How to solve the problem that device eth0 does not exist under centos?

1. Create a new ifcfg-eth0 file in the /etc/sysconfig/network-scripts/ directory;

2. Correctly set the DEVICE, BOOTPROTO, ONBOOT, IPADDR, GATEWAY, DNS1, DOMAIN, NETMASK, NETWORK, NAME, etc. of ifcfg-eth0,

For example:

            DEVICE=eth0                    物理设备名称
            IPADDR=192.168.1.x         IP地址
            NETMASK=255.255.255.0  子网掩码
            NETWORK=192.168.1.0     指定网络，通过IP地址和子网掩码自动计算得到
            GATEWAY=192.168.1.1     网关地址
            BROADCAST=192.168.1.255 广播地址，通过IP地址和子网掩码自动计算得到
            ONBOOT=[yes|no]             引导时是否激活设备
            USERCTL=[yes|no]           非ROOT用户是否可以控制该设备
            BOOTPROTO=[none|static|bootp|dhcp]    引导时不使用协议|静态分配|BOOTP协议|dhcp协议
            HWADDR=00:13:D3:27:9F:80   MAC地址
            NAME=eth0 名称

3. After the above settings, it can be successful under normal circumstances. If there are still problems, add # at the end of the file /etc/rc.d/rc.local ##ifup eth0 (/etc/rc.local script is executed after all other initialization scripts have been executed).

4. Restart the computer, OK.
