Step 1: install Passenger packages
These commands will install Passenger through Phusion's APT repository.
# 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 xenial main > /etc/apt/sources.list.d/passenger.list' sudo apt-get update # Install Passenger sudo apt-get install -y passenger
Step 2: 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 3: 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!
