    Warning: Operation not permitted @ rb_file_chown - /tmp/passenger.UjIOTlH/.
It appears that multiple Phusion Passenger instances are running. Please
select a specific one by running:

  passenger-status <NAME>

The following Phusion Passenger instances are running:

Name                       PID      Description
--------------------------------------------------------------------------
oR2Fxrti                   41650    nginx/1.18.0 Phusion_Passenger/6.0.6
XBKtMEPL                   89988    nginx/1.18.0 Phusion_Passenger/6.0.6

It is not normal for Nginx to start multiple Passenger instances. And your nginx config looks fine. How did you install Passenger and Nginx?

[ashrafalzyoud]

https://www.phusionpassenger.com/docs/tutorials/installation/meteor/

[ashrafalzyoud]

Ubuntu 20.04 Nginx 1.18 Passenger 6.0.6 Ruby 2.6.6

[CamJN]

Those instructions do not cover installing nginx.

[ashrafalzyoud]

I'm conflict how I install passenger with Nginx to good performance I'm see tow way 1- https://www.phusionpassenger.com/library/install/nginx/install/oss/tarball/

2-https://www.phusionpassenger.com/docs/advanced_guides/install_and_upgrade/nginx/install/oss/focal.html

Which the best ?!? @CamJN @FooBarWidget
