Using the hostname command with hostname can only temporarily change our hostname, which will revert to the original when we restart it.

# hostname newhostname enter hostname linux to change the hostname to linux, and use the uname-n command to view

At this time, our hostname has changed, why is it still Peithon on the left? try to reopen a terminal, or if you use Xshell, reopen the session.

To modify the configuration file if you want to permanently change your hostname, you have to go through the following steps

Modify the file / etc/sysconfig/network

Mylinux is the hostname to be set, then save exit, restart the system and you will read the configuration file and set the hostname to the new hostname.

If you do not want to restart the system at this point, you can use hostname mylinux to make temporary changes, so that even if the system is restarted, the hostname set in the read configuration file is the same as that set by your hostname, which is equivalent to the same.

In this way, the hostname setting is complete.

Generally speaking, the hosts file does not need to modify the hosts file to change the hostname. The / etc/hosts file provides a function of domain name resolution, similar to DNS. When the Linux system sends a domain name resolution request to the DNS server, it will query the / etc/hosts file. If there is a corresponding record in it, it will use the record in hosts.

So you can modify the / etc/sysconfig/network file if you want to change the hostname, but if you want to use distribution, you need to modify the hosts file only if you need to bind the hostname to ip.

At this point, the study on "how to permanently modify the host name of Linux" is over. I hope to be able to solve your doubts.
