Redhot cannot be networked ifconfig command only shows the way Lo does not show eth0 solution!

1. Specific steps to modify eth0 are as follows

Vi/etc/sysconfig/network-scripts/ifcfg-eth0,

I, enter the Insert edit mode, the specific parameters are set as follows:

Device=eth0

Bootproto=none (can also be set to static IP address)

Onboot=yes

Type=ethernet

netmask= Subnet Mask

Ipaddr=ip No.

gateway= Gateway (virtual machine Gateway)

ESC, exiting edit mode

shift+:wq! Save and Exit commands

2.ifconfig-a to see if it takes effect.

3.service network restart, Web server restart

"Pop-up interface eth0 is deciding eth0 IP information ... Failure: No link, do you want to check the cable? ”
This problem, change the bootproto=dhcp to Bootproto=static

4.ping +ip (IP of Linux), prompt success

5.ping + Gateway (gateway to Linux)

If Ping+ip succeeds, ping+ gateway fails, manually set DNS, command (vi/etc/resolv.conf)
(Add nameserver 10.0.0.1)

If you failed to set up DNS or ping the gateway, consider the problem with the virtual machine.
(Note: The virtual machine is NAT-networked, and the IP gateway in Linux must be consistent with the virtual Machine network segment)
