Apache2 Passenger (Google Compute Engine) catching SIGTERM over Ruby Version?

Question

For some reason, Apache doesn't seem to like my Rails App, running on Google Compute Engine with Phusion Passenger (using WEBrick, for now). I'm running this on Google's "Click-to-Deploy" ruby instance, which runs on Debian. I've also updated Ruby to 2.2.2 and set rvm use global 2.2.2 .

I go and rails s and start up the server, go to the IP address, and get a lovely 500 Internal Error from Apache saying my server configuration is all sorts of messed up. If i try going to <ip_address>:3000 I get no response from the server.

The configuration file (in /etc/apache2/sites-available/

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        DocumentRoot /home/nick/qwestera
        RailsEnv production
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory "/home/nick/qwestera">
                Options FollowSymLinks
                Require all granted
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

The logs (errors repeat):

A log entry I think may give me some insight:

[Fri Jul 31 18:55:23 2015] [notice] caught SIGTERM, shutting down
    [ 2015-07-31 18:55:24.5305 3807/7f317e333720 agents/Watchdog/Main.cpp:538 ]: Options: { 'analytics_log_user' => 'nobody', 'default_group' => 'nogroup', 'default_python' => 'python', 'default_ruby' => '/usr/local/rvm/gems/ruby-2.1.1/wrappers/ruby', 'default_user' => 'nobody', 'log_level' => '0', 'max_pool_size' => '6', 'passenger_root' => '/usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.58', 'passenger_version' => '4.0.58', 'pool_idle_time' => '300', 'temp_dir' => '/tmp', 'union_station_gateway_address' => 'gateway.unionstationapp.com', 'union_station_gateway_port' => '443', 'user_switching' => 'true', 'web_server_passenger_version' => '4.0.58', 'web_server_pid' => '5755', 'web_server_type' => 'apache', 'web_server_worker_gid' => '33', 'web_server_worker_uid' => '33' }

Specifically:

'default_ruby' => '/usr/local/rvm/gems/ruby-2.1.1/wrappers/ruby',

'passenger_root' => '/usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.58'

If you'll notice, I said I updated ruby to 2.2.2 because that's what the project I'm trying to run uses. However, Apache has default_ruby and passenger_root directories including ruby 2.1.1 . Would this be the issue? If so, how would I change this?

UPDATE:

Removing Require all granted has gotten me one step closer (this line is only necessary for version of Apache greater than 2.4, which mine is 2.2).

Now I'm getting a passenger page (with my rails app's favicon.ico showing up, yay!), letting me know Web application could not be started .

It has shown me the following errors:

Your Ruby version is 2.1.1, but your Gemfile specified 2.2.2 (Bundler::RubyVersionMismatch)

  /usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.58/helper-scripts/rack-preloader.rb:28:in `<main>'

Breakdown: I totally called that it was a Ruby version issue! Now, how do I let passenger know to look for stuff in the new Ruby dir for 2.2.2?

Interesting and possibly insightful:

$ ruby --version
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux]
$ ruby -version
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux]
-e:1:in `<main>': undefined local variable or method `rsion' for main:Object (NameError)

ruby -version returns a NameError , but ruby --version does not. Wtf?

UPDATE 2:

Well, I've updated /etc/apache2/apache2.conf to point to the new directory. However, my rails application isn't actually running. I just see an index of all the files and folders in my application. How do I tell it to start?

Answer 1

通过使用rvm uninstall 2.1.1卸载旧版本的 Ruby，使用rvm install 2.2.2重新安装新版本，然后使用passenger-install-apache2-module再次安装passenger 来解决。
