This post will introduce what should we do if the server IP address becomes invalid.
In our daily working, we may do some misoperations or encounter the system exceptions, due to these causes, the server IP address becomes invalid, after that, we query the current IP address through ipconfig command and find that the current IP address has disappeared or became other IP address.
At this moment, we cannot log in to the server, and the corresponding services are unusable.
So, what should we do when we meet this situation?
OK, next, I will introduce a solution for this problem. Please refer to the following method to restore the server IP address.
Step 1: Use PuTTY to remotely log in to the server through the ubp account (the default password is eLTE@com123).
Step 2: Run the following command to switch to the root user:
su - root
Password:(Enter the password of the root user. The default password is eLTE@com.)
Step 3: Run the following command to restart the OS network service:
service network restart
Step 4: Run the following command to check whether the IP address is restored:
ifconfig –a
