How to configure the network in linux

Configure Linux network

Use to enter the configuration file:

 vi /etc/sysconfig/network-scripts/ifcfg-eth0

The file opened now is the configuration file of the network card. To change the IP address, you must edit this file.

We want to modify the contents of the file, press the letter i key:

Change ONBOOT=no to ONBOOT=yes

Change BOOTPROTO=dhcp Change to BOOTPROTO=static

and add the following lines of characters

IPADDR=192.168.188.128

NETMASK=255.255.255.0

GATEWAY=192.168.47.2

DNS1=119.29.29.29

Note:

ONBOOT is set to yes, which means that the network card will follow the system Start together

BOOTPROTO is used to set the startup type of the network card. dhcp means automatically obtaining the IP address, static means manually setting the static IP address

IPADDR specifies the IP address (depending on the previously automatically obtained Address)

NETMASK specifies the subnet mask

GATEWAY specifies the gateway

DNS1 specifies the DNS IP address for Internet access

119.29.29.29 is a domestic DNSpod company Provide a public DNS

After completing the above changes, press the Esc key, then enter ":wq" and press Enter to exit the document just now.
