- Ensure SSH (port 22) is allowed, so you can access your server remotely.

Launch Your Instance

Review and Launch: Review your configuration settings and click on “Launch.”
Create a Key Pair: You’ll need a key pair to securely connect to your instance via SSH. Select “Create a new key pair,” name it, and download it to your computer. Keep this file safe—it’s your only way to access your instance.
Launch: Click on “Launch Instances.” Your instance will take a few minutes to start up.

Step 3: Connect to Your EC2 Instance

Access Your Instance via SSH

Locate Your Instance: In the EC2 dashboard, click on “Instances” to see a list of your instances. Find the one you just launched.
Copy the Public IP Address: You’ll need this to connect to your instance.
Open Terminal (Mac/Linux) or Command Prompt (Windows): Navigate to the directory where you downloaded your key pair file.
Change File Permissions (Linux/Mac): Ensure your key pair file has the correct permissions by running:
```
chmod 400 your-key-pair.pem
```
Connect to the Instance:

For Mac/Linux:

ssh -i "your-key-pair.pem" ec2-user@your-public-ip-address

For Windows (using PuTTY):

Convert the .pem file to .ppk using PuTTYgen.
Open PuTTY and enter the public IP address.
Under SSH -> Auth, browse and select your .ppk file.
Click “Open” to connect.

You’ll now have access to your EC2 instance via SSH.

Step 4: Install a Web Server

Install Apache or Nginx

Depending on your preference, you can install either Apache or Nginx to serve your website.

SCP (Linux/Mac): Use SCP to securely transfer files to your EC2 instance.

scp -i "your-key-pair.pem" -r /path/to/your/website ec2-user@your-public-ip:/var/www/html/

WinSCP (Windows):
- Connect to your instance using WinSCP.
- Drag and drop your website files into the /var/www/html/ directory.

Set Permissions

Ensure that the web server can read your files:

sudo chmod -R 755 /var/www/html/
sudo chown -R apache:apache /var/www/html/

Restart the Web Server

After uploading your files, restart the webserver to ensure everything is running correctly:

sudo systemctl restart httpd

For Nginx:

sudo systemctl restart nginx

Step 6: Configure a Domain Name

Point Your Domain to Your EC2 Instance

Obtain Your Instance’s Public IP: You can find it in the EC2 dashboard under “Public IPv4 address.”
Update DNS Settings: Go to your domain registrar’s DNS management page and create an “A” record that points to your EC2 instance’s public IP address.

Edit Apache/Nginx Configuration (Optional)

If you want to serve your website using your domain name:

For Apache:

Create a Virtual Host:

sudo nano /etc/httpd/conf.d/yourdomain.conf

Add the Following Configuration:

<VirtualHost *:80>
ServerName yourdomain.com
ServerAlias www.yourdomain.com
DocumentRoot /var/www/html
ErrorLog /var/log/httpd/yourdomain.com-error.log
CustomLog /var/log/httpd/yourdomain.com-access.log combined
</VirtualHost>

Save and Exit: Press CTRL + X, then Y to save.
Restart Apache:
```
sudo systemctl restart httpd
```

For Nginx:

Create a Server Block:

sudo nano /etc/nginx/conf.d/yourdomain.conf

server {
listen 80;
server_name yourdomain.com www.yourdomain.com;
root /var/www/html;

location / {
try_files $uri $uri/ =404;
}
}

Save and Exit: Press CTRL + X, then Y to save.
Restart Nginx:
```
sudo systemctl restart nginx
```

Your domain should now be pointing to your EC2 instance and serving your website.
