5. If not, start_udev

6. Failed reboot

Configure the NIC

1. Nic configuration file location:/etc/sysconfig/network-scrips/ifcfg-eth)

2. Items in the configuration file:

   1. DEVICE = eth0 (NIC nameKey! Used to identify NICs. There must be at least one item with MAC)

   2. BOOTPROTO = none

   3. IPADDR = XXX. XXX

   4. PREFIX (MASK number of digits) = 24/here also available MASK = MASK limit 255.0

   5. GATEWAT = XXX. XXX

   6. NM_CONTROLLED = no (this explanation can be found at the following link, thanks to the original author =)

   7. ONBOOT = yes

   8. TYPE = Ethernet

   9. IPV6INIT = no

   10. USERCTL = no

You can also enter setup in the command line to perform graphical configuration.

To make this configuration take effect, you need to disable graphical software taking over:

Service NetworkManager stop

Chkconfig NetworkManager -- level 35 off (cancel startup)
