How to modify the server name reference method under Linux system

To view the host name of Ubuntu, you can view it by command:

Hostname

Modifying the host name requires two files to be changed:

/etc/hostname

/etc/hosts

In the hostname file, change the original host name to a new one. In the Hosts file, you can

Change the original hostname portion of the 127.0.0.1 resolution to the new host name

---------------------------------------------------

1. Modify the Linux server name

# vi/etc/sysconfig/network

Networking=yes

Hostname=yourname//change in this HOSTNAME

2. Modify the name inside the/etc/hosts

# vi/etc/hosts

127.0.0.1 localhost.localdomain localhost

127.0.0.1 yourname//change in this hostname

3. Finally executed under the terminal

#hostname * * * *//***** for modified hostname

The hostname command only temporarily changes the hostname, and the host name is restored to the original after reboot.

To permanently change the host name, you need to modify the/etc/sysconfig/network file.
