Setup method of Centos boot up NIC

We do not boot the NIC, so we can only use

Ifup eth0

To start, but every time it feels so inconvenient. I hope to boot up the network card automatically

Then Baidu search for a moment found that you can modify the network card (ifcfg-eth0) parameters to boot, that is, open the Ifcfg-eth0 file

Example

code is as follows	copy code
[root@localhost ~]# vim/etc/sysconfig/network-scripts/ifcfg-eth0   device=eth0   HWADDR=08:00:27:fa :47:4c   nm_controlled=yes   onboot=yes------------------ Modify the following as Yes to boot automatically .   bootproto=dhcp   dns2=222.85.85.85   type=ethernet   dns1=222.88.88.88   userctl=no   PEERDNS=yes    ipv6init=no
