Linux Configuration Host Name

Method 1: Temporary configuration

hostname NING

The CRT is reconnected, and the server restart fails.

Method 2: Permanently configure

Step 1: Contains the most basic network information of the host for system startup.

[Email protected] ~]# vim/etc/sysconfig/networknetworking=yeshostname=ning

Step 2: Complete the function of host name mapping to IP address

[Email protected] ~]# vim/etc/hosts127.0. 0.1   NING

Step 3: Temporary entry into force. (If you do not perform this step, you will need to restart to take effect)

hostname NING

Note: In combination with Method 1, the server can be immediately active without restarting, and the restart can be used normally.
