INTRODUCTION
Our first task as being part of the HNG DevOps internship program was configuring Nginx on an ubuntu server and also customizing the HTML page.
Requirements
- Amazon linux 2, t2.micro instance
- port 22 (to enable ssh)
- port 80 (to enable access from anywhere)
steps
connecting to the instance
After setting up my instance with the appropriate keypair and security group, i launched the instanced and waited for it to run. thereafter i connected to the instance via the Ec2 instance connect.
Installing Nginx and starting it
the following commands are used in installing nginx on amazon linux 2
sudo yum update - to update any needed packages
sudo amazon-linux-extras install nginx1 - to install nginx
sudo systemctl start nginx - to start nginx
sudo systemctl enable nginx - to enable nginx
sudo systemctl status nginx - to verify that nginx is runing
To edit the index.html file
To add content to the index.html file
firstly you move to the location of the index.html file
Next i checked if i had the write permission to the index.html file
i didn't have write permission to the index.html file so i had to grant myself that permission before i was able to edit the file
after granting myself permission to the index.html file, i used nano to edit the file
after editing the file, i used ctrl + s to save the file and ctrl + x to exit the file.
next i restarted the nginx server
At this point i copied the public ip of my ec2 instance and pasted it on my browser and it displayed the nginx page with the edits i made in it
Challenges and solutions proffered
- The major challenge i encountered was moving into the location of the index.html file. since i was using the amazon linux 2, the location of the index.html file wasn't /var/www/html. so i had to look for where the file was and i found it located at /usr/share/nginx/html
Learning Outcome
This task has enabled me to learn the requirements for launching instances and hosting simple servers. It has also broaden my knowledge in the DevOps world.
