Project error on Linux unable to find hostname solution

Project error cannot find host name solution

Sometimes our project is running locally without problems, but it's a mistake to deploy to a Linux server.

Error: Java.net.UnknownHostException: hostname: hostname cannot find host name.

Workaround:

Modify the/etc/hosts file on the server

127.0.0.1 localhost localhost.localdomain Add the desired host name

Or

127.0.0.1 localhost Localhost.localdomain

127.0.0.1 Add the desired host name

If you want to modify the host name, you need to modify

Vi/etc/sysconfig/network file

Networking=yes

Hostname=localhost.localdomain

Localhost.localdomain Replace the name you want to change

Reboot is required after hostname change to take effect

Input reboot restart, restart good input hostname view, found hostname has changed

In addition, temporarily changing the hostname can be changed temporarily with the command hostname newhostname to avoid restarting.
