Installing Parse Server on an EC2 RHEL Instance

Today, we will be walking through the steps to create a Parse server on Amazon Web Services EC2 cluster. Since Parse is no longer providing hosting, we will need to setup our own Parse Server.

High Level Steps

  1. Launch an EC2 Instance
  2. Setup EC2 Security Groups
  3. Install NodeJS (6.X)
  4. Install Parse Server

Launch an EC2 Instance

First, login to your AWS console and select the EC2 Compute link. This will bring up the EC2 dashboard. Select the Launch Instance button. We're going to be setting up our Parse Server on the Red Hat Free Tier Eligible image, so click the Select button next to it. You may choose any Instance Type you like, but I'm going to stick with the default free tier type. Click Configure Security Group across the top and change the line for SSH Source to be My IP. This will only allow access via SSH from your current computer. Select Review and Launch and then Launch.

You will be presented with a popup to either select an existing key pair or create a new one. Let's create a new one. This will allow you to SSH into your AWS EC2 instance. I will name mine "aws-parse-server" and then select Download Key Pair. Save the .pem file somewhere that you can always have access to it. Select Launch Instance. You will get a confirmation that your instance is launching. Click on View Instances at the bottom of the page.

While we wait for our instance to finish initializing, let's move on to creating the necessary security groups.

Note: You can set this up during the instance configuration if you wish.

Create the Security Groups

// TODO: Fill this out

Connect to your Instance

Now it's time to connect to our newly created EC2 instance. Go to the Instances page, select the checkbox next to your new instance, and click Connect. We will be connecting with a standalone SSH client.

Copy the key into your .ssh directory

$ mv ~/aws-parse-server.pem ~/.ssh

Change the permissions

$ cd ~/.ssh
$ chmod 400 aws-parse-server.pem

SSH to the Instance

$ ssh -i "aws-parse-server.pem" ec2-user@<your_ec2_ip_address>

We're now ready to install NodeJS.

Installing NodeJS

Run these commands to ensure "sudo npm" can be run

sudo ln -s /usr/local/bin/node /usr/bin/node
sudo ln -s /usr/local/lib/node /usr/lib/node
sudo ln -s /usr/local/bin/npm /usr/bin/npm
sudo ln -s /usr/local/bin/node-waf /usr/bin/node-waf

Installing the Parse Server

Run Parse Server (pulled directly from GitHub)

$ npm install -g parse-server mongodb-runner
$ mongodb-runner start
$ parse-server --appId APPLICATION_ID --masterKey MASTER_KEY

Note: I had to add the --databaseURI mongodb://localhost/<dbname> option to the parse-server command to get this to run.
