I'm looking for advice on how to set up a fresh Linux server for deploying a web application. The application consists of a web API, a frontend, and background jobs, along with some routes that should only be accessible from specific IP addresses. I've got a lot of areas I'm curious about, including security hardening, user management, deployment workflows, monitoring, backups, and more. How do you tackle these tasks in real-world scenarios?

Let’s be real, you're trying to cover every base here, but keep it simple! With so many new tools and abstractions out there, a lot of modern operations are managed by cloud services now. Over-complicating for a single environment isn't really practical anymore.
In today's world, why manage everything on a VM when you can run containers? Think about using hosting services like Kubernetes to manage your docker workflows efficiently. It’ll save you headaches down the line!
For a production-ready server, start by hardening SSH access—limit it to key-based authentication and disable root login. Use tools like ufw or firewalld to set up your firewall with secure defaults. Containerize your applications using Docker or utilize systemd slices for better resource management. For deployments, I'd automate using CI/CD pipelines and securely store secrets using a solution like Vault. As for logging, consider sending logs to an external service such as EFK or Promtail while tracking performance with Prometheus and Grafana. Also, don’t forget about backups—test them regularly and make sure you're prioritizing your databases first!
I typically don’t back up configurations unless I’m not using a configuration management tool. The important stuff like databases and logs are backed up consistently.
I recommend implementing a three-tier model. Only ops personnel should have direct SSH access, while everyone else could deploy changes via CI/CD. You might want to use managed database services for ease, but definitely prioritize having backups in place and regularly validated!
But if everything's automated, why even allow people SSH access? A break-the-glass method for emergencies is much safer.
Honestly, how you handle this varies a lot with your company's size and needs. In smaller startups, automation is key because resources are tight. Just keep things simple—manual config for basics, add logging and CI/CD once your product picks up. Don't overcomplicate things before you have customers!
Exactly! Each stage of growth should inform your decisions, not the other way around.
Just make sure you start with a solid machine; it'll thank you later!
