Cannot deploy new rails app

Question

Followed the directions here: http://docs.webfaction.com/software/rails.html

And I have a new app called lab95.

In my nginx/conf/nginx.conf file I have:

server {
    listen             19855;
    passenger_enabled  on;
    root               /home/vegan/webapps/lab95ror/lab95/public;

However, I get a "passenger" error when I try to access the page.

Accepted Answer

I don't know why I'm posting this but here is the solution:

Hello,

There appears to be something wrong with my setup where my production environment, using mysql will not work (website says "We're sorry, but something went wrong.") but using development (sqlite3) works just fine.

I found the true cause of your error by setting the following value in your environments/production.rb file:

config.consider_all_requests_local = true

Here was the result (shown on the error page instead of the default worthless "something went wrong" message):

Sprockets::Helpers::RailsHelper::AssetPaths::AssetNotPrecompiledError in Home#index Showing /home/vegan/webapps/lab95ror/lab95/app/views/layouts/application.html.erb where line #5 raised: kickstrap.css isn't precompiled

..So your problem was being caused by non-pre-compiled assets. I told Rails to auto-compile your assets by setting this in production.rb:

config.assets.compile = true

Now your site works: http://vegan.webfactional.com/

(I also disabled the "consider_all_requests_local" setting for your security.)

Please do me a favor: summarize and post this solution onto the Community page so other people can also benefit from this solution.

Let me know if you have any questions.

The nginx log should provide more verbosity if you change the error log level to debug,

# edit ./nginx/conf/nginx.conf
error_log /path/to/file debug;

With this data you should be able to figure out why passenger is failing.

Thanks, @johns

However, last night the problem got worse, as I cannot start or stop the server itself:

[vegan@web349 lab95]$ ../bin/start
nginx: [emerg] bind() to 0.0.0.0:19855 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:19855 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:19855 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:19855 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:19855 failed (98: Address already in use)
nginx: [emerg] still could not bind()
[vegan@web349 lab95]$ rails server
-bash: rails: command not found
[vegan@web349 lab95]$ ../bin/stop
../bin/stop: line 7: kill: (25709) - No such process
[vegan@web349 lab95]$

The pid in your ~/webapps/<application>/nginx/logs/nginx.pid does not match your current running nginx process. You will need to manually kill the process by first getting a list of your processes:

ps -u username -o pid,command

Then kill the nginx processes with:

kill <PID>

After that you should be able to start with the standard bin/start and stop with bin/stop since the pid in nginx.pid should match now.

Thanks. I killed those processes, the server is back up, I finally got it to write to the mysql database, now it just says "We're sorry, but something went wrong." on the page.

The error log has been changed to verbose and now says:

I followed the instructions here: http://docs.webfaction.com/software/rails.html#installing-multiple-gems-with-bundler

When I switched the env to development, it worked fine, switching back to production, it gave me the same error.

So I assume it has something to do with mysql. However, looking at the phpmyadmin of my mysql db, everything migrated and installed correctly (it appears).
