Centos automatically starts the network

Centos60 (Final) version system originally installed on a virtual machine. after installation, it is not logged on to the virtual machine by default because the crt is used for each login, crt cannot be connected (Nic not started ). Next, let's modify and view the network card used. [Hcr @ slave2

Centos6.0 (Final) version system originally installed on a virtual machine. after installation, it is not logged on to the virtual machine by default because the crt is used for each login, crt cannot be connected (Nic not started ).

Next, modify it.

Check the network card used.

[Hcr @ slave2 ~] $ Ifconfig

Then go to the linux network configuration Directory

[Hcr @ slave2 ~] $ Cd/etc/sysconfig/network-scripts modify the Nic configuration as follows (ONBOOT = yes auto-start configuration)
[Hcr @ slave2 network-scripts] $ cat ifcfg-eth1
DEVICE = "eth1"
NM_CONTROLLED = "yes"
ONBOOT = yes
TYPE = Ethernet
BOOTPROTO = none
DEFROUTE = yes
20174_failure_fatal = yes
IPV6INIT = no
NAME = "System eth1"
IPADDR = 192.168.1.13
PREFIX = 24
GATEWAY = 192.168.1.1
HWADDR = 00: 0C: 29: 8C: BF: DF

After the configuration, restart the crt connection operation. you do not need to log on to the VM every time.
