How to Update the SSL Domain Certificate After Self-Hosting a JihuLab Code Platform

-
  Background After deploying a self-hosted JihuLab code platform, the domain's SSL certificate expired, making the management interface inaccessible.

Implementation Steps 1. Locate the Certificate Configuration in JihuLab Run the following command to check the actual certificate paths configured in JihuLab: grep -nEi "external_url|ssl_certificate|ssl_certificate_key|letsencrypt" /etc/gitlab/gitlab.rb The output will look similar to the following: external_url 'https://explore.com' nginx['ssl_certificate'] = "/etc/gitlab/ssl/explore.com.pem" nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/explore.com.key" Based on the configuration above, the certificate files are located in the following directory: /etc/gitlab/ssl/ 2.

The second option was slightly less ideal: modify the existing editor's source code to add a code block button and the logic required to display syntax highlighting. Unfortunately, Blogger does not provide a way to directly modify the editor's source code either. Both approaches had reached a dead end. I asked AI for alternat...
