How to modify the Linux host name

Linux is a bit of a hassle, even modifying the hostname is no exception. Let's take a look at the specific methods below.

When Linux is installed, its default hostname is localhost. It takes 3 steps to modify the Linux host name.

Use hostname to modify the current host name.

Hostname new-hostname

Modify the/etc/sysconfig/network configuration file so that the next time you restart it, use the new host name.

Open a/etc/sysconfig/network file and modify Hostname=new-hostname.domainname.

The modified/etc/sysconfig/network file is as follows:

Networking=yes

Hostname=new-hostname.localdomain

Modify the native domain name resolution file/etc/hosts so that the native application can parse the new hostname.

Edit file:/etc/hosts

Modified: xxx.xxx.xxx.xxx new-hostname.domainname New-hostname

(Here XXX represents the network address of the machine, it can also be the loopback address 127.0.0.1)

The modified/etc/hosts file is as follows:

127.0.0.1 localhost.localdomain localhost

127.0.0.1 New-hostname.localdomain New-hostname
