I have upgraded ruby version from 2.3.1 to 3.0.2 and also done related changes.
On server, after deployment, nginx server cant start and giving error for old version.
I have checked ruby version with login user in ubuntu and rvm list , new 3.0.2 version is set as default version.
Error log:

How to set ruby version to passenger from rvm?
passenger check ruby command gives two different output:
Command: passenger-config about ruby-command
With Sudo user (rvm command not detected):
root#ip-:/usr/bin# passenger-config about ruby-command
passenger-config was invoked through the following Ruby interpreter:
Command: /usr/bin/ruby2.3
Version: ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]
To use in Apache: PassengerRuby /usr/bin/ruby2.3
To use in Nginx : passenger_ruby /usr/bin/ruby2.3
To use with Standalone: /usr/bin/ruby2.3 /usr/bin/passenger start
The following Ruby interpreter was found first in $PATH:
Command: /usr/bin/ruby
Version: ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]
To use in Apache: PassengerRuby /usr/bin/ruby
To use in Nginx : passenger_ruby /usr/bin/ruby
To use with Standalone: /usr/bin/ruby /usr/bin/passenger start
System user(login user where rvm command detected):
current$ passenger-config about ruby-command
Your RVM wrapper scripts are too old, or some wrapper scripts are missing. Please update/regenerate them first by running:
rvmsudo rvm get stable && rvm reload && rvmsudo rvm repair all
If that doesn't seem to work, please run:
rvmsudo rvm wrapper ruby-3.0.2 --no-prefix --all
Please provide any clue, how to set passenger ruby default version or how to solve this error.

Answer 1

As passenger is designed to server multiple (Rails) applications on one webserver, there are config options per virtual host (actually per dirctory) to set the environment for each application.
see https://www.phusionpassenger.com/docs/references/config_reference/apache/ and https://www.phusionpassenger.com/docs/references/config_reference/nginx/
RVM installs wrappers for each installed ruby in i.e. ~/.rvm/wrappers/ruby-3.0.2/ruby and you can tell passenger to use this ruby for your application.
in an apache config, you can write:
<Directory "/path/to/you/rails/app">
PassengerRuby "/home/your-user/.rvm/wrappers/3.0.2/ruby"
RailsEnv production
</Directory>
passenger-config tells you what wrapper to use, but you must set the ruby environment first. My passenger-config outputs this comment:
Notes for RVM users
Do you want to know which command to use for a different Ruby interpreter? 'rvm use' that Ruby interpreter, then re-run 'passenger-config about ruby-command'.
