Set the static IP for fedora or redhat


I believe friends who have used Linux Fedora/redhat know that it is easy to set a fixed network in the GUI, but they don't know how to modify it in the text mode. 
Setting a static IP for the Fedora system has the advantage of not using DHCP to assign an IP. 
It is easier to find the computer you want, especially in a large network. It is most convenient to set a static IP for the computer. 
The static IP network address is the most suitable setting for SERVER.
The method as below:
1. open terminal,and input su - switch to root privileges

2. input ifconfig, Check which port is currently being used(port), and remember the HWaddr address for next step： 


3. Modify with this command
vi /etc/sysconfig/network-scripts/ifcfg-eth0

4. mainly modify the content as below:
DEVICE = eth2  <-- STEP2 mentioned PORT NUMBER
HWADDR = 00:0C:29:1D:00:00  <-- STEP2 motioned LAN card address
ONBOOT = yes 
IPADDR = 192.168.1.2
BOOTPROTO = none
NETMASK = 255.255.255.0
GATEWAY = 192.168.1.1
TYPE = Ethernet
DNS1 = 192.168.1.10
DNS2 = 192.168.1.11

5. save the file with this command:
:wp

6. and then restart the computer or input the command /etc/init.d/network reload to reload the network configuration to finish the job.

Done
