for Python apps + Ubuntu 16.10 (with APT)

This page describes the installation of Passenger through the following operating system or installation method: Ubuntu 16.10 (with APT). Not the configuration you are looking for? Go back to the operating system / installation method selection menu.

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: download and install your license key

Before you can install Passenger Enterprise, you need to download and install your license key. This is a regular file that you need to copy to your production server.

Please login to the Passenger Enterprise Customer Area.

Customer Area login screen

Click on the button to download the license key.

License key download button in the Customer Area

The license key will be downloaded to your local computer. Copy this license key file to your production server, for example using scp:

local-computer$ cd /path-to-your-local-computer-download-folder
local-computer$ scp -i your_ec2_key.pem passenger-enterprise-license 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.

Finally, login to your production server and save the file as /etc/passenger-enterprise-license:

local-computer$ ssh -i your_ec2_key.pem adminuser@yourserver.com
production-server$ sudo mv passenger-enterprise-license /etc/passenger-enterprise-license
production-server$ chmod 644 /etc/passenger-enterprise-license

Step 2: obtain your download token

Your download token is needed in order to install Passenger Enterprise. In the Customer Area, find your download token and copy it to your clipboard.

Step 3: install Passenger packages

These commands will install Passenger Enterprise + Apache module through Phusion's APT repository. Replace YOUR_DOWNLOAD_TOKEN with the download token you obtained in the last step.

# Install our PGP key and add HTTPS support for APT
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
unset HISTFILE
sudo sh -c 'echo deb https://download:YOUR_DOWNLOAD_TOKEN@www.phusionpassenger.com/enterprise_apt yakkety main > /etc/apt/sources.list.d/passenger.list'
sudo chown root: /etc/apt/sources.list.d/passenger.list
sudo chmod 600 /etc/apt/sources.list.d/passenger.list
sudo apt-get update

# Install Passenger Enterprise + Apache module
sudo apt-get install -y libapache2-mod-passenger-enterprise

Step 4: enable the Passenger Apache module and restart Apache

$ sudo a2enmod passenger
$ sudo apache2ctl restart

Step 5: 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 Apache has started the Passenger core processes. Run sudo /usr/sbin/passenger-memory-stats. You should see Apache 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

---------- Apache processes ----------
PID    PPID   VMSize    Private  Name
--------------------------------------
3918   1      190.1 MB  0.1 MB   /usr/sbin/apache2
...

----- Passenger processes ------
PID    VMSize    Private   Name
--------------------------------
12517  83.2 MB   0.6 MB    Passenger watchdog
12520  266.0 MB  3.4 MB    Passenger core
12531  149.5 MB  1.4 MB    Passenger ust-router
...

If you do not see any Apache processes or Passenger processes, then you probably have some kind of installation problem or configuration problem. Please refer to the troubleshooting guide.

Step 6: update regularly

Apache 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 Apache 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.

Next step

Now that you have installed Passenger, you are ready to deploy your Python application on the production server!
