Installing Passenger Enterprise + Apache on a Digital Ocean production server
for Node.js apps + generic installation through source tarball
On this page, we will install Passenger. After installing Passenger we can begin with deploying the app.

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 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: download tarball, upload to server and extract
Go to the "Files" section in the Customer Area and download the tar.gz file of the Passenger Enterprise version you want. Copy that file to your production server, for example using
local-computer$ cd /path-to-your-local-computer-download-folder local-computer$ scp passenger-enterprise-server-X.X.X.tar.gz email@example.com:
(Replace X.X.X with the Passenger Enterprise version)
On your production server, extract the tarball to some place permanent. Replace
/somewhere-permanent with the actual directory path that you want to extract to.
/opt is usually a good directory.
production-server$ tar -xzvf passenger-enterprise-server-X.X.X.tar.gz -C /somewhere-permanent
Step 3: install Ruby
Passenger supports multiple languages and its core is written in C++, but its installer and administration tools are written in Ruby, so you must install Ruby.
Even though Ruby is required, Ruby will normally not be loaded during normal operation unless you deploy a Ruby web application on Passenger. Passenger's dependency on Ruby is very minimal. See Lightweight Ruby dependency for details.
sudo apt-get update sudo apt-get install -y ruby rake
|Red Hat, CentOS, Fedora, ScientificLinux, Amazon Linux||
Enable EPEL, then run as root:
yum install -y ruby rubygem-rake
sudo pacman -S ruby
|Mac OS X||No action needed. Ruby is installed by default.|
|Other operating systems||Install Ruby from the Ruby website.|
Step 4: add Passenger to PATH
Add the Passenger
bin directory to your PATH, so that your shell can locate the Passenger commands.
Open your shell's system-wide startup file. If you're using bash, this is usually
/etc/bash.bashrc. Inside that file, add this to the end:
PATH=/somewhere-permanent/passenger-enterprise-server-X.X.X/bin:$PATH export PATH
Again, replace X.X.X with the Passenger version, and
/somewhere-permanent with the actual directory path.
When you're done, restart all your shells so that your new PATH takes effect.
Step 5: run the Passenger Apache module installer
Run the Passenger Apache module installer and follow the on-screen instructions:
At the end of the installation process, you will be asked to copy and paste a configuration snippet (containing
PassengerRoot, etc.) into your Apache configuration file.
Different operating systems and Apache installations have different conventions with regard to where the Apache configuration file is and how it is organized. Please read Working with the Apache configuration file if you are not familiar with it. That page is especially of interest for OS X Server >= 10.8 users because the configuration file may be at a surprising location.
Step 6: validate installation
After installation, please validate the install by running
sudo passenger-config validate-install. For example:
$ sudo 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 passenger-memory-stats. You should see Apache processes as well as Passenger processes. For example:
$ sudo 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.
How do I automate the downloading of the tarball?
You can use HTTP basic authentication.
In the Customer Area, right-click on the download button for the tarball and click "Copy link URL". That is the URL for the tarball. You can automate the download of that tarball by using
download as the HTTP username and your download key as the HTTP password.
Here is an example using curl:
$ unset HISTFILE $ curl --fail -L -o passenger-enterprise-server-5.0.8.tar.gz -u download:YOUR_DOWNLOAD_KEY 'https://www.phusionpassenger.com/orders/download?dir=5.0.8&file=passenger-enterprise-server-5.0.8.tar.gz'
Some of the dependent libraries are installed in non-standard locations. How do I allow the compiler to find them?
Please refer to Customizing the compilation process.
How do I pass additional flags to the compiler?
Please refer to Customizing the compilation process.
Now that you have installed Passenger, you are ready to deploy your Node.js application on the production server!
