Installing Passenger + Nginx on a Linux/Unix production server
for Python apps + Mac OS X

On this page, we will install Passenger. After installing Passenger we can begin with deploying the app.

Step 1: install Passenger package

You can install Passenger through Homebrew:

$ brew install nginx --with-passenger

Not using Homebrew? Please go back to the operating system selection menu and choose "Other" as operating system.

Step 2: enable the Passenger Nginx module and restart Nginx

Passenger is now installed, but it still needs to be enabled inside Nginx. Run brew info nginx --with-passenger and follow the instructions in the "Caveats" section:

$ brew info nginx --with-passenger
...
==> Caveats
...

To activate Passenger, ...
(...more instructions that you should follow...)

When you are done following the instructions, restart Nginx:

$ sudo launchctl unload /usr/local/opt/nginx/*.plist
$ sudo launchctl load /usr/local/opt/nginx/*.plist

Step 3: check installation

After installation, please validate the install by running sudo /usr/local/bin/passenger-config validate-install. For example:

$ sudo /usr/local/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/local/bin/passenger-memory-stats. You should see Nginx processes as well as Passenger processes. For example:

$ sudo /usr/local/bin/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.

Next step

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