I bought a Linux server in Alibaba Cloud, but the root user name turned out to be the product ID. Feeling very upset.

How to change the username, the following three simple steps can be done.

1.
Log in as the root user, or switch to the root user after logging in, and
enter: hostname in the terminal will display the current host name.



Enter vi /etc/sysconfig/network, then change the value after HOSTNAME= to the hostname you want to set.



2.
Change the hosts file under /etc, enter vi /etc/hosts at the prompt, and then change localhost.localdomain (may be other, please find the corresponding location according to the picture, here it is chenhaoxiang) to the desired setting hostname.



3.

Enter the reboot command to restart the server.

After restarting, log in, and then enter hostname to view the host name!
To sum up the above core command is:

vi /etc/sysconfig/network
vi /etc/hosts
reboot
