Linux Network Configuration

There are several methods to configure the Linux system network. Here we will introduce two common methods.

First, use the command ifconfig to configure. Use Ipconfig ethx x. x netmask x. x

The effect is as follows:

 

Generally, this configuration method is only used for testing, because after the machine is restarted, the configuration content will become invalid.

 

Method 2: vi/ect/sysconfig/network-scripts/ifcfg-ethx

This configuration method directly modifies the configuration file, and the configuration effect will always take effect.

Is the effect of the virtual machine configuration in this example. The specific parameters are not parsed:

Common Linux Network commands:

Modify DNS command:

# Vi/etc/resolv. conf

Nameserver 202 101.224.68

Nameserver 202.101.224.69

 

Long-term effectiveness:

Enable eth0: ifup eth0

Disable eth0: ifdown eth0

 

Temporary effect:

Enable NIC: ifconfig eth0 up

NIC: ifconfig eth0 down

Restart the server:

Service network restart or/etc/init. d/network restart

 

Configure the Host Name and Default Gateway:

Vi/etc/sysconfig/network

NETWORKING = yes whether to enable the System Network Function

HOSTNAME = centosmin
