passenger-config not set ruby version from rvm default

Question

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: 
App 7441 stdout:

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.

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'.
