How to change GitLab’s IP address

When using GitLab, sometimes we need to modify the IP address of GitLab. For example, when the IP address of the server changes, or when GitLab needs to be migrated from one server to another, we need to modify the IP address of GitLab. .

The following are the specific steps to modify the GitLab IP address:

1. Log in to the GitLab server and enter the GitLab installation directory.
2. Open the GitLab configuration file gitlab.rb, which is generally located in the /etc/gitlab/ directory.
3. Use an editor such as vim to open the gitlab.rb file, find the external_url line, and modify it to the new IP address.
4. Save and close the gitlab.rb file.
5. Run the sudo gitlab-ctl reconfigure command to reconfigure GitLab.
6. Restart the GitLab service and run the sudo gitlab-ctl restart command.
7. Modify GitLab's firewall rules and add the new IP address to the firewall whitelist to ensure that GitLab can be accessed normally.

After following the above steps to modify GitLab’s IP address, we can use the new IP address to access GitLab. It should be noted that if GitLab's IP address is inaccessible after modification, it can be solved by checking the firewall rules and re-running the gitlab-ctl reconfigure command.

When modifying the IP address in GitLab, we need to ensure that the new IP address and the original IP address are in the same LAN. If we migrate GitLab from one server to another, we also need to migrate the data on the original GitLab server to the new server. For details, please refer to GitLab official documentation.

In short, when modifying the IP address of GitLab, you need to pay attention to ensure that the server network is smooth, the firewall is set correctly, and follow the relevant instructions in the official GitLab documentation to ensure the normal operation of GitLab.
