How to solve the problem of CentOS network failure

1. Centos will not establish a local connection by default, at least in the virtual machine. Just create a new one yourself:

cd /etc/sysconfig/network- scripts/

vi ifcfg-eth0

DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
NM_CONTROLLED=yes

Save and exit.

Restart the network:

service network restart

2. Check whether the CentOS network configuration in the virtual machine is NAT

Modify the /etc/sysconfig/network-scprits/eth0 file

The IP value of BROADCAST must be consistent with the ip in VMNET8 and the last digit must be 255

The IP value of IPADDR must be consistent with the ip in VMNET8 and the last digit must be 1~255 The IP value of any value

GETWAY must be consistent with the IP in VMNET8 and the last digit is 2

Then restart the network.
