Refer to this guide to learn how to connect to an EC2 instance<https://scribehow.com/shared/How_to_Connect_to_an_AWS_EC2_Instance__czXjLrH1R1yAIXika6fGbA>

Log in to the **EC2 Linux instance** by connecting through AWS default **EC2 instance connect**

Use **sudo** to switch from **ec2-user** to root for administrative tasks on EC2 Instance to mitigate the risk of unintended alterations affecting system stability or security.

Type [[sudo su]] to switch from **ec2-user** to root; followed by pressing Enter

\
After sudo-ing to the root user trigger the **[[yum update]]** command to install any pending updates

Execute the [[yum install httpd]] command to install the httpd web server on the **Linux Instance**

After executing [[yum install httpd]]; the system will ask for the installation confirmation. Press "**y**" followed by an Enter to confirm the web server installation

**Note:** To avoid asking for user confirmation you can execute the alternative command -[[ yum install httpd -y]]

Use this command [[echo "It works" &gt; /var/www/html/index.html ]]to create the HTML file

Start the web server by executing [[systemctl start httpd]]and then enable it to start automatically on every boot by executing[[systemctl enable httpd]]
