<h2>2. Setting up LAMP</h2><hr>
<h4 id="section-2.1">2.1 System configuration</h4>
<p class="p-0 m-0 mb-1 mt-2">The first thing that should be always done when configuring a fresh linux install is to update
the repository list with <code>apt update</code> and then install the new packages with <code>apt upgrade</code>, so go ahead and insert these commands
in your terminal. With it, we're also going to install docker.io
</p>
<div class="code-snippet">
<p>sudo apt update</p>
<p>sudo apt upgrade</p>
<p>sudo apt install docker.io</p>
</div>
<hr>
<h4 id="section-2.2">2.2 Creating the docker containers</h4>
<p class="p-0 m-0 mb-1 mt-2">There is a LAMP stack container that we can use that is already preconfigured from <code>mattrayner/lamp</code>, so let's install it with this command</p>
<div class="code-snippet">
<p>sudo docker run -d --name lamp -i -t -p "80:80" -v ~/app:/app mattrayner/lamp:latest</p>
</div>
<p class="p-0 m-0 mb-0 mt-1">Here we are creating a docker container, detaching from its process with <code>-d</code>, giving it a <code>--name</code> of lamp, exposing it on the port 80 and binding
the container's /app dir to a directory with the same that will be created in the user's PWD folder. <br>
The <code>~/app</code> directory is the root folder of the apache+php webserver, in here you can place your css, html, php and js files.</p>
<p class="p-0 m-0 mb-1 mt-2">To check if the installation worked, check if the container is running with this command</p>
<div class="code-snippet pb-1">
<p>sudo docker ps</p>
<img src="img/lamp/ssl-3.png" class="img-fluid" alt="">
</div>
<p class="p-0 m-0 mb-1 mt-2">Then simply get your EC2 instance's public IP and put it in a browser, you should see something similar</p>
<img src="img/lamp/ssl-4.png" class="img-fluid" alt="">
<p class="p-0 m-0 mb-1 mt-2">Let's create an index.php file in the ~/app dir to see if it works</p>
<div class="code-snippet">
<p>cd ~/app</p>
<p>touch index.php</p>
</div>
<p class="p-0 m-0 mb-1 mt-2">Then you can edit the index.php file to show phpinfo() with either <code>vi</code>, <code>nano</code> or any other editor you like. The file content should look like this.</p>
<div class="file-snippet">
<div class="file-name">File: ~/app/index.php</div>
<div class="file-content"><?php phpinfo() ?></div>
</div>
<p class="p-0 m-0 mb-1 mt-2">Go to your EC2 instance's public IP and you should see that everything is working!</p>
<img src="img/lamp/ssl-5.png" class="img-fluid" alt="">
<hr><div class="d-flex"><h4 id="section-2.3">2.3 Creating the SSL certificate <h4 class="fst-italic fw-lighter">(optional)</h4></h4></div>
<p class="p-0 m-0 mb-1 mt-2">We are going to create the /ssl directory containing the ssl key and certificate in the user's home dir,
to do this follow the instructions from this command
</p>
<div class="code-snippet">
<p>mkdir ~/ssl</p>
<p>sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ~/ssl/key.pem -out ~/ssl/cert.pem</p>
</div>
<p class="p-0 m-0 mb-1 mt-2">If you've done everything correctly, you should see a cert.pem and a key.pem file in the ~/ssl directory</p>
<img src="img/lamp/ssl-2.png" class="img-fluid" alt="">
<p class="p-0 m-0 mb-1 mt-2">Now we need a way to bind the SSL certificate to our website, to do this we can create a proxy using <code>fsouza/docker-ssl-proxy</code> on the port 443
by specifying where our certificates are, in this case we put them in <code>~/ssl</code>. You also need to set the correct domain for your machine
</p>
<div class="code-snippet">
<p>sudo docker run -d --name ssl-proxy --link lamp:proxyapp -p 443:443 -e DOMAIN=<span style="color: red">YOUR_EC2_PUBLIC_IP</span> -e TARGET_PORT=80 -e TARGET_HOST=proxyapp -e SSL_PORT=443 -v ~/ssl:/etc/nginx/certs --restart unless-stopped fsouza/docker-ssl-proxy</p>
</div>
<p class="p-0 m-0 mb-1 mt-2">If you go to https://YOUR_EC2_PUBLIC_IP you shold now see this</p>
<img src="img/lamp/ssl-6.png" class="img-fluid" alt="">
<p class="p-0 m-0 mb-1 mt-2">And you can see the certificate information</p>
<img src="img/lamp/ssl-7.png" class="img-fluid" alt="">
<hr>
<h4 id="section-2.4">2.4 Automating the startup</h4>
<p class="p-0 m-0 mb-1 mt-2">Now that everything is configured let's create a .sh script to start/restart the lamp and proxy-ssl containers authomatically</p>
<div class="file-snippet">
<div class="file-name">File: ~/run-lamp.sh</div>
<div class="file-content"># Start docker<br>
sudo docker start<br><br>
# Kill all running containers<br>
containers=$(docker ps -q)<br>
docker kill $containers<br><br>
# Start lamp and proxy server<br>
sudo docker start lamp<br>
sudo docker start proxy-ssl</div>
