Drama, suspense, and a happy ending included! 🔥
Introduction
As a budding DevOps enthusiast, my first hands-on task was setting up an NGINX web server on a fresh Ubuntu machine. This foundational exercise aimed to teach server configuration, troubleshooting, and deploymentskills critical for roles like DevOps Engineers and CI/CD Pipeline Engineers. In this blog, Ill walk through my journey, the hurdles I faced, and how this task aligns with my career aspirations.
Approach
Step 1: Installing NGINX
I started by updating the Ubuntu package repository and installing NGINX using:
sudo apt update && sudo apt install nginx -y
After installation, I verified NGINX was running:
sudo systemctl status nginx
Step 2: Creating the Custom HTML Page
I replaced the default landing page by creating a new index.html at /var/www/html/:
sudo nano /var/www/html/index.html
I added a simple HTML template with the required message:
<!DOCTYPE html> <html> <head> <title>DevOps Stage 0</title> </head> <body> <h1>Welcome to DevOps Stage 0 - TechGee</h1> </body> </html>
Step 3: Configuring Permissions and Testing
To avoid permission issues, I set ownership of the /var/www/html directory to the web server user:
sudo chown -R www-data:www-data /var/www/html
Finally, I reloaded NGINX to apply changes:
sudo systemctl reload nginx
Challenges & Solutions: The Oops, I Did It Again Edition 🎭
Challenge 1: Firewall, the Over-enthusiastic Bouncer 🚧
Problem : My NGINX server was ready to party, but Ubuntu's firewall (UFW) was like, NOPE. Port 80? Never heard of her.
Solution : I whispered the magic words:
sudo ufw allow 'Nginx HTTP'
Moral of the Story : Firewalls are the bouncers of the internet. Always check the guest list.
Challenge 2: Permission Denied? More Like Permission Confused 🔑
Problem : My HTML page was MIA. Turns out, the file was owned by rootthe ultimate gatekeeper. NGINX, being a mere mortal (www-data), couldn't read it. 🙈
Solution : I handed over the keys:
sudo chown www-data:www-data /var/www/html/index.html # "Here, NGINX. This is YOUR house now." 🏠
Moral of the Story : Sharing is caring. Especially with web servers.
Challenge 3: The Case of the Missing Semicolon 🔍
Problem : I edited the NGINX config like a coding wizard until I missed a ;. NGINX responded with: Error 500: LOL, nice try.
Solution : I became Sherlock Holmes of Syntax:
sudo nginx -t # Spoiler: It yelled, Missing semicolon at line 13! 🕵
Then, I raided the logs:
tail -f /var/log/nginx/error.log # Ah-ha! Theres the culprit! 🎯
Moral of the Story : Semicolons are the pepperoni of codesmall but essential. 🍕
Why You'll Remember This Forever 🌟
Firewalls are drama queens.
Permissions are like relationships; communication is key.
Typos are the universes way of keeping you humble.
Now go forth, and may your servers never throw a tantrum again! 🚀
(P.S. If all else fails, scream sudo!! and pray.) 😇
