After installing centos, you cannot connect to the network.

After installing centos, you cannot connect to the network.

Today I got a CentOS 6.4 version. After the installation, I found that the network cannot be connected, and I cannot PING the internet.

I searched the internet and found that after Linux is installed, the NIC is not started by default. Next we will modify the NIC configuration file.

Setp1:
The Code is as follows:
Cd/etc/sysconfig/network-scripts/

Setp2:
The Code is as follows:
Vim ifcfg-eth0 // open the ifcfg-eth0 File class as follows:
DEVICE = eth0
HWADDR = 00: 0C: 29: 2E: 37: F0
TYPE = Ethernet
UUID = 69cd9740-184f-49b7-857f-e450e57f265b
ONBOOT = yes // change to yes
NM_CONTROLLED = yes
BOOTPROTO = dhcp
Save the modification and exit.

Setp3:
The Code is as follows:
/Etc/init. d/network restart // restart the network
Ifconfig // view IP Address
Ping www.111cn.net//pingtest
