生产中rbenv的乘客设置

Question

I have some questions.

1. Is it possible (or appropriate) to use rbenv in production?
2. Should I install rbenv as root, or normal user?
3. How passenger can know which ruby version it should use for a application? Can passenger recognize .ruby-version file?

Answer 1

I would not recommend to use rbenv in production, cause it have sense only if you required to have several ruby versions in the same time.

I would recommend to use system ruby from you OS repository.

EDIT: According your questions

1. It is quite possible to use rbenv in production (as well as rvm ). But I would recommend to use ruby from your OS repositories.
2. You may install either as user or root.
3. You should use .ruby-version to point to the right version.
