Deploying a Meteor app on an AWS production server
with Passenger in Apache mode on Ubuntu 14.04 LTS (with APT)

On this page you will learn how you can deploy your app to a server that is running Passenger. You can either follow these instructions with your own app, or you can use the sample Meteor app we prepared.

1 Transferring the Meteor package to the server

1.1 Build package

To deploy your Meteor app to production, we need to create a packaged version of it. A packaged Meteor app contains the Meteor runtime and various other necessary things for running a Meteor app in production.

In order to provide you appropriate instructions, please choose your Meteor version: >= 1.4 <= 1.3.5.1

Inside your application's code directory, on your local computer, use the meteor bundlemeteor build command to create a Meteor package tarball.

$ meteor bundle package.tar.gz

$ meteor build --server-only ../new_package && mv ../new_package/*.tar.gz package.tar.gz

1.2 Upload package to the server

Copy the package to your production server, for example using scp:

local-computer$ scp -i your_ec2_key.pem package.tar.gz adminuser@yourserver.com:

Replace adminuser with the name of an account with administrator privileges or sudo privileges. This is usually admin, ec2-user, root or ubuntu.

1.3 Login to your server, create a user for the app

Login to your server with SSH:

$ ssh -i your_ec2_key.pem adminuser@yourserver.com

Replace adminuser with the name of an account with administrator privileges or sudo privileges. This is usually admin, ec2-user, root or ubuntu.

Now that you have logged in, you should create an operating system user account for your app. For security reasons, it is a good idea to run each app under its own user account, in order to limit the damage that security vulnerabilities in the app can do. Passenger will automatically run your app under this user account as part of its user account sandboxing feature.

You should give the user account the same name as your app. But for demonstration purposes, this tutorial names the user account myappuser.

$ sudo adduser myappuser

We also ensure that that user has your SSH key installed:

$ sudo mkdir -p ~myappuser/.ssh
$ touch $HOME/.ssh/authorized_keys
$ sudo sh -c "cat $HOME/.ssh/authorized_keys >> ~myappuser/.ssh/authorized_keys"
$ sudo chown -R myappuser: ~myappuser/.ssh
$ sudo chmod 700 ~myappuser/.ssh
$ sudo sh -c "chmod 600 ~myappuser/.ssh/*"

1.4 Extract package

You need extract the package to a permanent location on the server. A good location is /var/www/APP_NAME. Let us create that directory.

$ sudo mkdir -p /var/www/myapp

Replace myapp and myappuser with your app's name and your app user account's name.

Now let us extract the package:

$ cd /var/www/myapp
$ tar xzf ~/package.tar.gz
$ chown -R myappuser: .

Your extract app package directory now lives on the server at /var/www/myapp/bundle.

2 Preparing the app's environment

2.1 Install MongoDB

During development, the Meteor runtime takes care of starting MongoDB for you. MongoDB is the database engine that Meteor uses. But a packaged Meteor app does not start MongoDB for you. Instead, a packaged Meteor app expects that MongoDB is already running somewhere, and that you tell the app where that MongoDB instance is.

2.2 Login as the app's user

All subsequent instructions must be run under the application's user account. While logged into your server, login under the application's user account as follows:

$ sudo -u myappuser -H bash -l

2.3 Install app dependencies

Your application has various dependencies. They must be installed. Most of these dependencies are Javascript libraries, managed by npm. You can install them by running npm install in your app's package directory, under the programs/server subdirectory:

$ cd /var/www/myapp/bundle/programs/server
$ npm install --production

Your app may also depend on services, such as Redis etc. With the exception of MongoDB, installing services that your app depends on is outside of this tutorial's scope.

3 Configuring Apache and Passenger

Now that you are done with transferring your app's code to the server and setting up an environment for your app, it is time to configure Apache so that Passenger knows how to serve your app.

3.1 Go back to the admin account

You have previously logged into your app's user account in order to prepare the app's environment. That user does not have sudo access. In the next steps, you need to edit configuration files, for which sudo access is needed. So you need to switch back to the admin account.

This can be done by simply exiting the shell that was logged into the app's user account. You will then be dropped back to the admin account. For example:

# This is what you previously ran:
admin$ sudo -u myappuser -H bash -l
myappuser$ ...

# Type `exit` to go back to the account you were before
myappuser$ exit
admin$ _

3.2 Edit Apache configuration file

We need to create an Apache configuration file and setup a virtual host entry that points to your app. This virtual host entry tells Apache (and Passenger) where your app is located.

$ sudo nano /etc/apache2/sites-enabled/myapp.conf

Replace myapp with your app's name.

Put this inside the file:

<VirtualHost *:80>
    ServerName yourserver.com

    # Tell Apache and Passenger where your app's code directory is
    DocumentRoot /var/www/myapp/bundle/public
    PassengerAppRoot /var/www/myapp/bundle

    # Tell Passenger that your app is a bundled Meteor app
    PassengerAppType node
    PassengerStartupFile main.js

    # Tell your app where MongoDB is
    SetEnv MONGO_URL mongodb://localhost:27017/myappdb
    # Tell your app what its root URL is
    SetEnv ROOT_URL http://yourserver.com

    # Relax Apache security settings
    <Directory /var/www/myapp/code/public>
      Allow from all
      Options -MultiViews
      # Uncomment this if you're on Apache > 2.4:
      #Require all granted
    </Directory>
</VirtualHost>

Replace yourserver.com with your server's host name and replace /var/www/myapp/bundle with your application's package directory path. Replace myappdb with an appropriate MongoDB database name. Also be sure to set ROOT_URL to an appropriate value.

When you are done, restart Apache:

$ sudo apache2ctl restart

3.3 Test drive

You should now be able to access your app through the server's host name! Try running this from your local computer. Replace yourserver.com with your server's hostname, exactly as it appears in the Apache config file's ServerName directive.

$ curl http://yourserver.com/
...your app's front page HTML...

If you do not see your app's front page HTML, then these are the most likely causes:

1. You did not correctly configure your ServerName directive. The ServerName must exactly match the host name in the URL. For example, if you use the command curl http://45.55.91.235/ to access your app, then the ServerName must be 45.55.91.235.
2. You did not setup DNS records. Setting up DNS is outside the scope of this tutorial. In the mean time, we recommend that you use your server's IP address as the server name.

Next step

Congratulations, you have successfully deployed your app!
