乘客5 / Capistrano

Question

I'm trying to deploy Rails application to VPS via Capistrano. I have passenger standalone installed on the VPS and using capistrano-passenger gem with default configuration.

Running cap deploy produces the following output:

DEBUG [3197887c] Finished in 0.046 seconds with exit status 0 (successful).

DEBUG [8557b41e]        

I am using default config. Anything I can do to make it work?

Answer 1

Use set :passenger_restart_with_touch, true as a workaround on Passenger 5.

It's a known problem as described in https://github.com/capistrano/passenger/issues/26

Answer 2

我最近碰到了这个，我的情况是因为deploy用户需要对passenger-config命令使用sudoer权限。

Answer 3

Do you have gem 'passenger' in your Gemfile ?. Make sure that the passenger gem is installed on your VPS. Also, if you need Nginx as the webserver then run the following command on your VPS rvmsudo passenger-install-nginx-module . Let me know if you need further help.

Answer 4

First of all you should make sure passenger is currently running on your server, so try: rvmsudo bundle exec passenger start . If this worked, try to set:

set :passenger_in_gemfile, true
set :passenger_restart_with_sudo, true

and then check the setup with cap production passenger:restart .
(applicable to Passenger Standalone installed via Gemfile).
