Solution to failure to access the Internet when Centos is installed on the machine to be installed

Centos is installed on a VMware Workstation Virtual Machine. When the system cannot access the Internet, we can use the following common configuration methods:

TYPE = Ethernet

DEVICE = eth0 # Virtual Network Interface Name
HWADDR = 00: 0C: 29: 60: FF: 8B # Nic mac address
ONBOOT = yes # activated when the system is started

NM_CONTROLLED = yes # takes effect immediately after modification.
BOOTPROTO = dhcp # Use the automatically assigned IP Address

Note: Select NAT for Virtual Machine network connection.

When we install Centos on the server, the production environment configuration is as follows:

Configure static IP addresses:

[Root @ sky9896 ~] # Cat/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE = eth0
BOOTPROTO = static
IPADDR = 117.40.239.12

NETMASK = 255.255.240.0
GAEWAY = 117.40.239.1
HWADDR = 00: 21: 97: 68: F2: 70
TYPE = Ethernet
UUID = 480c82ca-d673-466d-902a-9f31eaeb897c
ONBOOT = yes
NM_CONTROLLED = no

Set Gateway:

[Root @ sky9896 ~] # Cat/etc/sysconfig/network

NETWORKING = yes
HOSTNAME = sky9896
GATEWAY = 117.40.239.1

Set DNS

[Root @ sky9896 ~] # Cat/etc/resolv. conf
