Installing Passenger + Nginx on a Linux/Unix production server
for Meteor apps + Ubuntu 17.10 (with APT)
On this page, we will install Passenger. After installing Passenger we can begin with deploying the app.

Heads up: limited package support for non-LTS Ubuntu versions
Before we continue, you should know that the Ubuntu version you selected is a non-LTS (Long Term Support) version. This means that Canonical — the company that created Ubuntu — only supports this particular Ubuntu version for 1 year.
Because of this short support cycle by Canonical, we only provide Passenger package updates for this Ubuntu version for 6 months. That's when the next Ubuntu version comes out.
So when the next Ubuntu version is released, you must upgrade your system to that new Ubuntu version. Otherwise you won't receive Passenger updates in the form of .deb packages from us anymore.
If you don't like having to upgrade your Ubuntu system every 6 months, then you should use an LTS version of Ubuntu. Canonical supports LTS versions for 5 years, and we provide Passenger package updates for LTS versions for 5 years too.
Now that you know this, let's move on.
Step 1: install Passenger packages
These commands will install Passenger + Nginx module through Phusion's APT repository. At this point we assume that you already have Nginx installed from your system repository. If not, you should do that first before continuing.
# Install our PGP key and add HTTPS support for APT sudo apt-get install -y dirmngr gnupg sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7 sudo apt-get install -y apt-transport-https ca-certificates # Add our APT repository sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger artful main > /etc/apt/sources.list.d/passenger.list' sudo apt-get update # Install Passenger + Nginx module sudo apt-get install -y libnginx-mod-http-passenger
Step 2: enable the Passenger Nginx module and restart Nginx
Ensure the config files are in-place:
$ if [ ! -f /etc/nginx/modules-enabled/50-mod-http-passenger.conf ]; then sudo ln -s /usr/share/nginx/modules-available/mod-http-passenger.load /etc/nginx/modules-enabled/50-mod-http-passenger.conf ; fi $ sudo ls /etc/nginx/conf.d/mod-http-passenger.conf
If you don't see a file at
/etc/nginx/conf.d/mod-http-passenger.conf; then you need to create it yourself and set the
passenger_root config options. For example:
passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini; passenger_ruby /usr/bin/passenger_free_ruby;
When you are finished with this step, restart Nginx:
$ sudo service nginx restart
Step 3: check installation
After installation, please validate the install by running
sudo /usr/bin/passenger-config validate-install. For example:
$ sudo /usr/bin/passenger-config validate-install * Checking whether this Phusion Passenger install is in PATH... ✓ * Checking whether there are no other Phusion Passenger installations... ✓
All checks should pass. If any of the checks do not pass, please follow the suggestions on screen.
Finally, check whether Nginx has started the Passenger core processes. Run
sudo /usr/sbin/passenger-memory-stats. You should see Nginx processes as well as Passenger processes. For example:
$ sudo /usr/sbin/passenger-memory-stats Version: 5.0.8 Date : 2015-05-28 08:46:20 +0200 ... ---------- Nginx processes ---------- PID PPID VMSize Private Name ------------------------------------- 12443 4814 60.8 MB 0.2 MB nginx: master process /usr/sbin/nginx 12538 12443 64.9 MB 5.0 MB nginx: worker process ### Processes: 3 ### Total private dirty RSS: 5.56 MB ----- Passenger processes ------ PID VMSize Private Name -------------------------------- 12517 83.2 MB 0.6 MB PassengerAgent watchdog 12520 266.0 MB 3.4 MB PassengerAgent server 12531 149.5 MB 1.4 MB PassengerAgent logger ...
If you do not see any Nginx processes or Passenger processes, then you probably have some kind of installation problem or configuration problem. Please refer to the troubleshooting guide.
Step 4: update regularly
Nginx updates, Passenger updates and system updates are delivered through the APT package manager regularly. You should run the following command regularly to keep them up to date:
$ sudo apt-get update $ sudo apt-get upgrade
You do not need to restart Nginx or Passenger after an update, and you also do not need to modify any configuration files after an update. That is all taken care of automatically for you by APT.
Now that you have installed Passenger, you are ready to deploy your Meteor application on the production server!
