Rails/Nginx/Passenger ERROR: Phusion Passenger doesn't seem to be running

Question

I was setting up Passenger and Nginx for my Rails App (Mac OS X 10.11). I used these commands:

gem install passenger
rvmsudo passenger-install-nginx-module

All these gets installed perfectly.

Added nginx path in .bash_profile:

export PATH=$PATH:/opt/nginx/sbin/

My nginx conf:

passenger_root /Users/MyUserName/.rvm/gems/ruby-2.2.5@rails4115/gems/passenger-5.3.4;
passenger_ruby /Users/MyUserName/.rvm/gems/ruby-2.2.5@rails4115/wrappers/ruby;

server {
    listen 443;
    ssl on;
    server_name app1-local.staging.com;
    rails_env development;
    passenger_enabled on;
    root /Users/MyUsername/Desktop/Github/MainApp/public;
    ssl_certificate /opt/nginx/ssl/mainapp.com.crt;
    ssl_certificate_key /opt/nginx/ssl/mainapp.com.key;
}

server {
    listen 443;
    ssl on;
    server_name app2-local.staging.com app3-local.staging.com app4-local.staging.com local.staging.com;
    rails_env development;
    passenger_enabled on;
    root /Users/MyUsername/Desktop/Github/MainApp2/public;
    ssl_certificate /opt/nginx/ssl/mainapp.com.crt;
    ssl_certificate_key /opt/nginx/ssl/mainapp.com.key;
}

server {
    listen 80;
    server_name app1-local.staging.com;
    rails_env development;
    passenger_enabled on;
    root /Users/MyUsername/Desktop/Github/MainApp/public;
}

server {
    listen 80;
    server_name app2-local.staging.com app3-local.staging.com app4-local.staging.com local.staging.com;
    rails_env development;
    passenger_enabled on;
    root /Users/MyUsername/Desktop/Github/MainApp2/public;
}

After this I started nginx: sudo nginx, it worked. Now if I visit local.staging.com, I get 502 internal server error.

Nginx error logs displays: upstream prematurely closed connection while reading response header from upstream

If I do passenger-status, it outputs:

Phusion Passenger is currently not serving any applications.

Note: on running, passenger-config validate-install command, it says Everything looks good. :-)

EDIT

Output of sudo passenger-memory-stats:

-------- Apache processes --------

----------- Nginx processes ------------

63016 62366 2411.6 MB 1.5 MB nginx: worker process

63014 2417.6 MB 3.3 MB Passenger ust-router

63602 2457.3 MB 5.7 MB Passenger core

EDIT 2 Now in nginx error.log, getting:

Process aborted! signo=SIGSEGV(11), reason=#0, signal sent by PID 0 with UID 0, si_addr=0x0, randomSeed=1534502322

And

upstream prematurely closed connection while reading response header from upstream

Any help here?

Well, you're seeing `Everything looks good` this is weird, can you check `sudo passenger-memory-stats` ? — Kedarnag Mukanahallipatna, Aug 17 '18 at 06:18
@KedarnagMukanahallipatna I have added the output of `memory-stats` in Question. — Rahul Sagore, Aug 17 '18 at 06:40
Have you set [these](https://stackoverflow.com/a/40656207/4160532) ? — Kedarnag Mukanahallipatna, Aug 17 '18 at 07:43
I am not using Apache or Capistrano. But yeah I have added variable in .bash_profile: export PASSENGER_INSTANCE_REGISTRY_DIR=/temp. Mentioned in the question. After adding variable I have used `source ~/.bash_profile` and even restarted terminal. — Rahul Sagore, Aug 17 '18 at 07:46
