Understanding Certbot and Redirect Challenges on AlmaLinux: A Personal Experience
Navigating SSL Certificate Setup on New Linux Servers
Setting up SSL certificates on a freshly migrated Linux server can sometimes feel like solving a complex puzzle. Recently, I encountered a perplexing issue while working with Certbot on my AlmaLinux server, which hosts multiple websites. Although I’m fairly comfortable with Linux, I’m still learning the ropes and often troubleshoot through experimentation and patience.
Background: Migration from CentOS to AlmaLinux
My server, previously running CentOS Stream 8, now runs AlmaLinux. The migration involved manually transferring website files via rsync, along with configurations and database backups. Everything appeared to be in place, yet I soon faced unexpected challenges when trying to secure my sites with HTTPS.
The Redirect Loop Problem
When attempting to obtain SSL certificates using Certbot, I encountered redirect loop errors. Certbot would report issues related to infinite redirects, preventing successful certificate installation. Interestingly, this problem didn’t occur on my previous CentOS setup but surfaced on AlmaLinux.
Troubleshooting Approach: Seeking Answers Beyond Search Engines
While searching online can often resolve such issues, I found better guidance by consulting AI tools. I copy-pasted Certbot logs, error messages, and relevant virtual host configurations into a local language model. Unfortunately, initially, the advice was unhelpful, leaving me puzzled.
A Simple Solution Emerges
After some trial and error, I decided to open each virtual host configuration file in Vim, then save and close them. Rerunning Certbot afterward, I was surprised to find the errors had suddenly disappeared. I hadn’t made any significant changes—simply reopening and closing the files seemed to trigger the fix.
Reflections and Takeaways
This experience highlights how sometimes, small, seemingly insignificant actions can resolve tricky server issues. Despite feeling inexperienced, persistence and methodical troubleshooting can lead to success—even if the solution is as simple as refreshing a configuration file.
Final note: When working with SSL certificates and server redirects, don’t overlook the basics. Sometimes, a little patience (and a trip for a whiskey) can make all the difference.
