Phusion Passenger Nginx Module for Python & Ruby Deployments

Dedicated thread for discussion Centmin Mod .08 beta03's 130.00beta01 latest /addons/passenger.sh implementation for Phusion Passenger Nginx Module for Nginx which allows deployment of both Python, NodeJS, Meteor and Ruby based applications with Nginx.

Fixed /addons/passenger.sh addon with the following commits in Centmin Mod .08 beta03 at least.

The /addons/passenger.sh addon installs Phusion Passenger Nginx Module for Nginx which allows you to deploy both Python, NodeJS, Meteor and Ruby based applications with Nginx.

• update addons/passenger.sh for rvm gpg security & code improvement · centminmod/centminmod@9daa680 · GitHub
• update addons/passenger.sh fix post-install instructions · centminmod/centminmod@4c3b401 · GitHub
• update inc/nginx_configure.inc disable Clang if NGINX_PASSENGER=y ena… · centminmod/centminmod@66d8d0a · GitHub

Unfortunately, Clang compiler has issues compiling Nginx with Phusion Passenger's Nginx module, so if NGINX_PASSENGER=y is set in centmin.sh, the Nginx configure routine auto switches back to GCC compiler. Which works fine

With Centmin Mod 130.00beta01's addons/passenger.sh as at August 15, 2022

To install Phusion Passenger for Nginx on Centmin Mod Nginx

1. run /addons/passenger.sh to install required software including passenger, node.js, ruby, rails, and rubygem

Code:

cd /path/to/addons
chmod +x passenger.sh
./passenger.sh install

End of install will give next step instructions for completing Phusion Passenger install

2. then log out of SSH windows session

3. log back into SSH and and set NGINX_PASSENGER=y in persistent config file /etc/centminmod/custom_config.inc you have or create manually

---

4. then run centmin.sh menu option 4 to recompile Nginx

5. Enable /usr/local/nginx/conf/passenger.conf include file. Scripts will setup a /usr/local/nginx/conf/passenger.conf include file in nginx.conf which by default is commented out.

Code:

http {
#include /usr/local/nginx/conf/passenger.conf;

need to uncomment it and restart nginx

Code:

http {
include /usr/local/nginx/conf/passenger.conf;

Contents of /usr/local/nginx/conf/passenger.conf

Code:

passenger_root /usr/local/rvm/gems/ruby-3.1.2/gems/passenger-6.0.14;
passenger_ruby /usr/local/rvm/bin/ruby;
passenger_max_pool_size 4;

Notes:

• Updated for 123.09beta01 see example here.

 

Personally, I am still a noob when it comes to utilising Phusion Passenger Nginx module, so if other users here are more familiar, I welcome any guides or sharing of how you use Phusion Passenger and Nginx with your NodeJS, Python or Ruby web apps

 

did you make sure to do steps 2 and 3 above ?

To troubleshoot, you need to check the nginx upgrade log at /root/centminlogs and instructions under Sharing logs and errors heading for using Pastebin.com or Gists to share a sanitised version of the contents of the nginx upgrade log.

 

sounds like step 1 for /addons/passenger.sh failed to install properly. You should have a /root/centminlogs log entry for passenger i.e. centminmod_passenger_install_${DT}.log which you can share via pastebin or gist too

 

looks good to me

Code:

-------------------------------------------
Setup /usr/local/nginx/conf/passenger.conf
-------------------------------------------
Passenger root located at: /usr/local/rvm/gems/ruby-2.2.3/gems/passenger-5.0.22
[1;32;40m-------------------------------------------
(B[m[1;33;40mSetup completed...
(B[m[1;32;40m-------------------------------------------

only thing i can think of is step 2 and 3 above being missed as the path wouldn't have been setup for that same user SSH session until you log out and back in

check /usr/local/nginx/conf/passenger.conf exists and try recompiling nginx again via centmin.sh menu option 4 and see

 

also what's output for

Code:

which passenger-config

and

Code:

passenger-config --nginx-addon-dir

 

indeed.. Centmin Mod is full root non-sudo only

 

excellent

 

did you log out of SSH session after passenger.sh addon install ?

Code:

------------------------------------------
Setup /usr/local/nginx/conf/passenger.conf
-------------------------------------------
Passenger root located at: /usr/local/rvm/gems/ruby-2.2.4/gems/passenger-5.0.23
[1;32;40m-------------------------------------------
(B[m[1;33;40mSetup completed...
(B[m[1;32;40m-------------------------------------------
(B[m
Log out and log back into your SSH session

Uncomment lines in /usr/local/nginx/conf/passenger.conf to enable passenger
Nginx needs to have passenger nginx module compiled for it to work
1. edit centmin.sh and set NGINX_PASSENGER=y
2. run centmin.sh menu option 4 to recompile Nginx
3. uncomment/enable /usr/local/nginx/conf/passenger.conf include file in nginx.conf
4. then check that passenger module is in list of nginx modules via command:
nginx -V
This script only installs passenger, node.js, ruby, rails, rubygem and is provided as is.

what type of web hosting and server you using ? Xen, OpenVZ, KVM or dedicated ? who's web host ? are you by any chance using or setup sudo users ?

also what's output for

Code:

which passenger-config

and

Code:

passenger-config --nginx-addon-dir

 

@Juli112 think i found the problem and solution, testing it out now

 

Updated both 123.08stable and 123.09beta01 with fix, so you can update your copy via centmin.sh menu option 23 submenu options 1 and 2 or just 2 if you previously have ran submenu option 1

Upgrading Centmin Mod Code to Latest Version

Upgrading Centmin Mod involves 2 parts.

1. Upgrading the actual Centmin Mod code outlined at Upgrade Centmin Mod - CentminMod.com LEMP Nginx web stack for CentOS This is heart of Centmin Mod where the code is the engine that runs centmin.sh shell based menu and all the automation you're accustomed to.
2. Upgrade software that Centmin Mod installed or manages. For this part following outline at Upgrade - How to upgrade Centmin Mod | Centmin Mod Community

So essentially, you can upgrade from .07 to .08 in place, but not everything is upgraded as some things like server initial environment setup isn't changed i.e. how swap, tmp setup and allocation are created etc. The main parts from part 2 above are what in place upgrades do i.e. Nginx and PHP-FPM compilation and config/settings parameters and MariaDB version from 5.5 to 10.0.x. If you want the full environment changed including tmp and swap setup to .08's configuration, then you would need a fresh OS install and fresh .08 initial install. You can think of it like upgrading Windows 7 to Windows 8. An in place upgrade will upgrade code but won't change your computer environment from when you installed Windows 7 i.e. disk configuration and partition sizes won't change from when you initially installed Windows 7. Only way to change that would be fresh Windows 8 install.
