Connecting to EC2 Instance
Using SSH to Connect
When it comes to connecting to your EC2 instance, one of the most common methods is using SSH (Secure Shell). SSH allows you to securely access your instance’s command line interface. To connect using SSH, you will need to have the private key associated with your EC2 instance. This key is crucial for authenticating your access to the instance.
To connect using SSH, you can use the following command:
ssh -i your-private-key.pem ec2-user@your-instance-public-ipReplace “your-private-key.pem” with the path to your private key file, “ec2-user” with the default username for Amazon Linux instances, and “your-instance-public-ip” with the public IP address of your EC2 instance.
Using PuTTY to Connect
If you are using a Windows operating system, PuTTY is a popular choice for connecting to your EC2 instance. PuTTY is a free and open-source terminal emulator that supports SSH, Telnet, and serial port connections. To connect using PuTTY, you will need to convert your private key to a PuTTY-compatible format using PuTTYgen.
Once you have converted your private key, you can open PuTTY and enter the public IP address of your EC2 instance in the “Host Name” field. Make sure to select the SSH protocol and specify the private key file under “Connection” > “SSH” > “Auth”.
Accessing EC2 Instance via AWS Management Console
If you prefer a graphical user interface, you can also access your EC2 instance through the AWS Management Console. Simply log in to your AWS account, navigate to the EC2 dashboard, and select the instance you want to connect to. From the instance details page, you can click on the “Connect” button to access the instance using the browser-based SSH client.
Hosting a Website on EC2
Installing Web Server Software
When it comes to hosting a website on an EC2 instance, one of the first steps you’ll need to take is installing web server software. The most popular choice for web server software is Apache, which is known for its reliability and performance. To install Apache on your EC2 instance, you can use the package manager specific to your operating system. For example, if you are using a Linux-based AMI, you can use the following command:
sudo yum install httpd
Once Apache is installed, you can start the service and configure it to automatically start on boot. This will ensure that your website is always accessible to visitors.
Uploading Website Files
After installing the web server software, the next step is to upload your website files to the EC2 instance. You can do this using Secure Shell (SSH) or File Transfer Protocol (FTP) clients. Simply connect to your EC2 instance using the appropriate credentials and navigate to the root directory where your website files should be stored. From there, you can upload your HTML, CSS, JavaScript, and other files to make your website live on the internet.
Configuring DNS Settings
Once your website files are uploaded to the EC2 instance, you’ll need to configure the Domain Name System (DNS) settings to point your domain name to the EC2 instance’s public IP address. This involves setting up a DNS record with your domain registrar or DNS provider. You can create an A record that maps your domain name to the EC2 instance’s IP address, ensuring that visitors can access your website by typing in your domain name in their web browser.
