Cloud Server ECS Linux host modifies host name

There are two ways to modify cloud server ECS Linux hostname, which is outlined in this article.

Temporary effective modification

Using the command line to modify the hostname hostname (customizable), the login shell takes effect.

You can see that the shell is in effect when you log back in

Permanent change in effect

Take the CentOS system as an example, you need to change the configuration file to take effect, modify the hostname= hostname (customizable) in the/etc/sysconfig/network, and reboot takes effect.

If it is an Ubuntu system, you will need to modify the file/etc/hostname to modify its hostname to the new hostname.

Finally, you need to replace the old hostname in/etc/hosts with the new host name 127.0.0.1. As shown

Note: If it is a CentOS 7 operating system, you can use the command hostnamectl set-hostname 主机名 to modify, and then re-SHELL login after the change.
