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.
Click on the Install button in the Customer Area.
Click on the button to download the license key.
The license key will be downloaded to your local computer. Copy this license key file to your production server, for example using
local-computer$ cd /path-to-your-local-computer-download-folder local-computer$ scp passenger-enterprise-license email@example.com:
adminuser with the name of an account with administrator privileges or sudo privileges.
Finally, login to your production server and save the file as
local-computer$ ssh firstname.lastname@example.org 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 through Phusion's APT repository.
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-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 unset HISTFILE sudo sh -c 'echo deb https://download:YOUR_DOWNLOAD_TOKEN@www.phusionpassenger.com/enterprise_apt artful 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 sudo apt-get install -y passenger-enterprise
Step 4: 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.
Step 5: update regularly
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
After an update, you should restart all your Passenger instances so that the updates take effect.
Now that you have installed Passenger, you are ready to deploy your Python application on the production server!
