I'm been working on a rails 3.1 app with one other dev.
I've just pulled some of his recent changes, using git. And am now getting a 403 on any page I try to visit.
You don't have permission to access / on this server.
I'm running the site locally through passenger.
Oddly, when I start the app using rails' internal server. I can visit the site at http://0.0.0.0:3000
Looking at the changes in this recent pull, the only files have changed are some javascripts, some html the application.rb, routes.rb and a rake file.
How do I debug this, I'm a bit lost on where to start?
EDIT:
If I roll back to an earlier version the site works, through passenger. Which leads me to believe the problem is within the rails app, rather than an Apache error. Or it could be a permissions thing, can git change file permissions in this way?
IMHO this is a configuration error in Apache or wrong directory layouts. Make sure that the passenger_base_uri still points to the public folder inside your rails project and that there are no hidden .htaccess files which block access. Also verify that your sym-links are correct (if there are any). Also check your Apache error log.
Start by launching your console to see if rails and your app can be loaded.
In your application root directory type :
rails console

I'm new to RoR.
I was able to install Rails and host it in Webrick (Sample App with "Welcome" controller) in my windows.
Now i have a Unix Weblogic Server along with a dedicated domian.
After exporting the .WAR file using Warbler, i accessed the Oracle Admin Console from where i deployed the .WAR file in the dedicated domain. I did all this for the Sample app with only the Welcome controller in it.
But even after deploying the WAR file, on accessing the Domain along with the Port Number (:9002) i ended up with 404 file not found error On looking at the server logs,there wasn't any records relating to any error. The Application must have been deployed properly. I assume that i must have missed out on some basic configurations in the routes.rb or similar files before deploying. Can anyone Guess what are all the possibilities and if possible can anyone help me by pointing to any tuts that cover the Steps to be carried out for configuration before deployment. do i need to install both JRuby and Rails inside the server before depolyment?
I can't really guess with Eror 404 only.
You can try mapping your rails app rack config to a different base_uri.
All you need to do is wrap the existing 'run' command in a map block
try doing this in your rails 'config.ru' file:
map '/mydepartment' do
run Myapp::Application
end
Now when you 'rails server' the app should be at localhost:3000/mydepartment .
Not sure if this will give you the desired outcome, but worth a try.
One more thing you also add this to your config/environments/production.rb and config/environments/development.rb (if on production mode):
config.action_controller.asset_path = proc { |path| "/abc#{path}" }
otherwise when you call your helpers such as stylesheet_link_tag in your views, they will generate links without the "/abc".
Also, find some guides you may refer for good support.

I'm having a real tough time diagnosing a 500 error from my application running in production. I've had it working before, but after re-deploying via Capastrano I am unable to get it going.
Here are the facts:
The server is setup with nginx + passenger, and I'm using
PostgreSQL.
Static assets are working properly, as in I'm able to access them just fine in a browser.
I can access the rails console via RAILS_ENV=production bundle exec rails console and perform Active Record actions (like
retrieving data from the db).
Within console, I can run app.get("/"), which returns a 500 error as well (after first showing the query that was run to load
the model).
The production.log file is never written to. I've set permissions 777 on it just for the hell of it. I've also set the log level to
:debug with nothing to show for it.
The nginx log (which passenger also uses) shows no indication of errors, it just notifies about cache misses.
Because nothing of use is being logged, I have no idea what to do here. I've tried setting full permission on the entire app directory with no help. Restarted the server multiple times, nothing. The database is there and rails can clearly communicate with it. I'm not sure what I did to get it to run the first time around. I just don't know why rails isn't outputting anything to the log.
Okay, I figured this out. The app ran fine in development mode, so I knew something production-specific was screwing it up. I went into config/environments/production.rb and changes these settings:
# Full error reports are disabled and caching is turned on
config.consider_all_requests_local = false # changed from true
config.action_controller.perform_caching = true # changed from false
And then after restarting passenger, rails showed me the error w/ stacktrace. Turns out I was forgetting to precompile the asset pipeline!
Things to check
1) Are you sure you are running in production environment?
Check to see if any entries are in the development.log file
2) Set up your app to email you when a 500 error occurs with a full stack trace. I use the Exception Notifier gem but there are plenty of other solutions for this.
3) When checking your app in the console are you sure you are starting the console in production mode? It is possible that the app is not starting up at all and you just forgot to set the production param thereby thinking that the app runs fine when it doesn't.
4) Are you getting an nginx 500 error or the Rails 500 error? If nginx then it is likely that your app is not starting at all and highly unlikely that you will get any rails error in your log file. The assets are static files and navigating to them proves nothing other than that they exist.
5) Are you sure you are checking the right folder on the server? Sounds really stupid but capistrano could be deploying the app to a folder that is different to the folder that nginx is looking for for your app so double check both the folder capistrano is deploying to and the folder that nginx is looking for are the same.
Just a suggestion, I would use puma rather than passenger. It's awesome with nginx.
My problem is passenger's log file (error.log) has nothing. Then it's a rotation log issue. Run
passenger-config reopen-logs
solved my problem. More.
Have you tried running in development mode to see if the error reports itself?
I wrote a demo HelloWorld Rails app and tested it with WEBrick (it doesn't even use a DB, it's just a controller which prints "hello world"). Then I tried to deploy it to a local Apache powered with Passenger. In fact this test is just to get Passenger working (it's my first deploy on Apache). Now I'm not even sure that Passenger works, but I don't get any error on the Apache side.
When I fire http://rails.test/ the browser shows the Rails 500 error page - so I assume that Passenger works. I want to investigate the logs, but it happens that production.log is empty! I don't think it's a permission problem, because if I delete the file, it is recreated when I reload the page. I tried to change the log level in conf/environments/production.rb, tried to manually write to log file with Rails console production and
Rails.logger.error('asdf')
it returns true but nothing gets written to production.log. The path (obtained per Rails.logger.inspect) is correct, and I remark that the file is recreated if I manually remove it. How can I know what's going on?
(I already checked the Apache logs, plus I set the highest debug level for Passenger but it seems a Rails problem, so is not logged by the server)
Assuming you're running Rails 3.2.1, this is a bug. It was patched in 3.2.2.
If you can't upgrade to 3.2.2 for any reason, this comment on GitHub has a workaround:
# config/initializers/patch_rails_production_logging.rb
Rails.logger.instance_variable_get(:#logger).instance_variable_get(:#log_dest).sync = true if Rails.logger
Setting this works on Rails 3.2.11:
Rails.logger = ActiveSupport::BufferedLogger.new(Rails.root.join("log","production.log"))
I have a Rails app that is running on a production server with Apache and Phusion Passenger. The app works fine locally when using Mongrel, but whenever I try to load a URL on the production server, it returns HTTP 500. I know the server is working properly, because I can get the static elements of the application (e.g., JavaScript files, stylesheets, images) just fine. I've also checked the Passenger status and it is loading the app (it must be, since the app's 500 Internal Server Error page is returned, not just the default Apache one). Also, when I load the app via script/console production and do something like app.get("/"), 500 is also returned.
The problem is that there is nothing in the log files to indicate the problem. production.log is empty. The Apache error logs show no problems with Apache, either. I'm stumped as to what's going on and I'm not sure how to diagnose the problem.
I know I may have been a bit vague, but can anyone give a suggestion on what the problem may be? Or at least a way I can go about diagnosing it?
The answer for this specific situation was a problem with my app. One of the model classes used a different database connection than the rest of the app. This database connection was not configured properly. I think the reason why nothing was written to the log files is that Rails bailed out without having any idea what to do.
Since it may be helpful for others to see how I diagnosed this problem, here was my thought process:
The issue couldn't be with Apache: no errors were written into the Apache log files.
The issue probably wasn't with Passenger: Passenger wasn't writing any errors to the Apache log file, and it seemed to be loading my app properly, since passenger-status showed it as loaded and it was display my app's 500 Internal Server Error page (not the default Apache one).
From there I surmised that it must be something broken in my app that happened very early on in the initialization phase, but wasn't something that caused the app to completely bail and throw an exception. I poked around in the Phusion Passenger Google Group, and ultimately stumbled upon this helpful post, which suggested that the error may be a database connectivity issue. Sure enough, removing this misconfigured database and all references to it made the app work!
Have you tried running the app locally using Passenger?
Try running the application locally on Mongrel in Production mode, to make sure that there's no weird issues with that particular environment. If that works, then you know that it's not an issue with your codebase. Since your static components are being served properly, that tells me that Apache is working fine. The only gear in the system left is Passenger. At this point, I would say it's an improperly configured Passenger. You should post up your Passenger config file, and ask the question on ServerFault.
A couple of things to try :
Have you gone though the following from the docs:
6.3.7. My Rails application’s log file is not being written to
There are a couple things that you
should be aware of:
By default, Phusion Passenger runs Rails applications in production
mode, so please be sure to check
production.log instead of
development.log. See RailsEnv for
configuration.
*
By default, Phusion Passenger runs Rails applications as the owner
of environment.rb. So the log file can
only be written to if that user has
write permission to the log file.
Please chmod or chown your log file
accordingly.
See User switching (security) for details.
If you’re using a RedHat-derived Linux
distribution (such as Fedora or
CentOS) then it is possible that
SELinux is interfering. RedHat’s
SELinux policy only allows Apache to
read/write directories that have the
httpd_sys_content_t security context.
Please run the following command to
give your Rails application folder
that context:
Have you checked your vhost or httpf.conf file ? Do you have any logging directives ?
Check the top level apache log file
Try setting PassengerLogLevel to 1 or 2 or 3, as shown here http://www.modrails.com/documentation/Users%20guide.html#_passengerloglevel_lt_integer_gt
Do you have any rack apps installed ?
My suggestion would be to go right back to "Hello World" land and create the smallest possible Ruby example application and upload it to see if there is a problem with Passenger or Ruby on the server.
May be a silly suggestion but I suggest you start by increasing the logging levels on production while you are testing. Do this in config/environments/production.rb and use:
config.log_level = :debug
This should at least get you some sort of backtrace so you can start to find the problem.
If you still get nothing - you may find that you have an issue with something as simple as a missing gem/plugin on your production server. That sort of thing may well manifest as a "500" error and just not be very verbose for you.
Can you run the test suite on your production server?
I have a Rails app that I have successfully tested with Mongrel and Webkit. Now I want to test deployment. I set up a VMWare Image using Ubuntu 8.04. I have installed Rails following this method https://help.ubuntu.com/community/RubyOnRails with the exception of using Gems 1.3 instead of 1.2. I have configured and installed Passenger. However, when I visit my sites index (http://some.ip.that.i'm.testing/) I simply get the directory index of my rails site. I should note that since I'm testing I just dumped my app in /var/www.
My Apache2 error.log file shows this and this only:
[Tue Sep 30 15:10:41 2008] [notice] Apache/2.2.8 (Ubuntu) Phusion_Passenger/2.0.3 configured -- resuming normal operations
Any idea what could be causing this problem? It seems Passenger is configured properly, but I'm not sure why my rails app is not displaying and why the site's directory listing is.
Thanks.
Two questions:
1) Is Rails running at all on the server? Passenger should start Rails automatically on first request - if you do a ps, do you see it running?
2) Which directory are you seeing - is it your rails directory or the public/ directory? If it's the former, your symlink is likely pointing the wrong place (it should go to public/).
(I've seen this problem before and am trying to remember how I debugged it... these are my first two thoughts.)
