Configuration of Linux networks, DNS settings, management of Linux hosts through Remote Tools

(1) Enter the NIC configuration directory

[Email protected] ~ #]cd/etc/sysconfig/network-scripts/

Comments:

CD indicates which level of directory to enter

CD behind and directory to add a space, otherwise will be reported no such file or directory (files and directories cannot be found)

(2) View the configuration file under the NIC directory

[[email protected] network-scripts]# ls

Comments:

LS means to view the file under the directory;

Find a file called Ifcfg-eth0, where you can configure IP, subnet mask, gateway;

(3) Edit the network card configuration file

[Email protected] network-scripts]# VI ifcfg-eth0

Comments:

VI means to edit this file

Edit Ifcfg-eth0, modify the following places

Type=etherent (type of NIC is Ethernet card)

Onboot=yes (whether to start the network card)

Bootproto=static (How to obtain an IP address)

ipaddr=192.168.0.103 (set IP address)

netmask=255.255.255.0 (set subnet mask)

gatway=192.168.0.1 (set Gateway)

Comments:

The static IP address is set here, and if a DHCP server assigns the address of the Linux host, you can

Bootproto=dhcp,ip address, subnet mask, gateways do not need to be manually configured, automatically get it.

(4) Restart the network card to make the configuration file effective

Service Network restart

All four states must be OK, otherwise the settings are problematic and need to be reset
