RUNBOOK05: UPDATE THE PACKAGES AND INSTALL APACHE ON AN AWS EC2 REDHAT INSTANCE USING A BASH SCRIPT
Hi tech beauties,
Hope you are having a wonderful Saturday.
So far in this beautiful cloud journey I have introduced you to cloud computing and shown you how to
- Create an AWS Free Tier Account
- Launch a Linux EC2 Instance
- Connect to a Linux EC2 Instance using an SSH Client
- Update the software packages and install Apache on an EC2 Instance manually
In this post I will show you how to write a bash script to update the software packages on an EC2 instance and install Apache. It is the same exact thing that we did here but we will be using a script instead so we don’t have to manually run the commands going forward
After connecting to my RedHat Linux EC2 instance, I will be in the home directory and will create two files.
The first file is index.html
vi /home/ec2-user/index.html
The second file is the bash script. A Bash script is a plain text file which contains a series of commands.
The bash script will have the command to update the software using yum on a new EC2 Instance, install httpd, start httpd and copy index.html from /home/ec2-user/ to /var/www/html/
vi /home/ec2-user/script.sh
I ran the script using super user privileges and piped the output to log.txt.
sudo sh script.sh > log.txt
Once the command finished I went to the public IPv4 address as listed in the EC2 Dashboard for this instance and was able to view the web page
This was a fun project and a great refresher on AWS for me. I was able to use my Linux skills as well. Thank you for joining me on this AWS Journey.
