I tried to deploy my rails app on nginx and ubuntu via capistrano like the tutorial on the page https://gorails.com/deploy/ubuntu/14.04. but at the end i get an error message:
Incomplete response received from application
in my browser. this is probably an error from passenger, but how can i figure out what to do?
Your rails_env production don't have required set up,probably missing secret_key_base.
Open /etc/nginx/sites-available/default
and change the rails_env to development:
rails_env production;
to
rails_env development;
If the app is loading it's not a passenger issue.
Production Solution:
rake secret
/yourapp/config/secrets.yml
secret_key_base
Restart the passenger app :
touch /yourapp/tmp/restart.txt
This error occurs because you didn't set the secret_key_base. Follow these steps to fix it:
Go to your rails app directory
cd /path/rails-app
Generate secret key base
rake secret RAILS_ENV=production
Set environment variable
SECRET_KEY_BASE=<the-secret-key-base>
Restart the Rails app
touch /path/rails-app/tmp/restart.txt
I had this problem over the weekend (it turned out there was an incompatibility between my versions of passenger and ruby).
However, nobody seems to be mentioning: the actual error might appear in /var/log/apache2/errors.log, not in any custom log.
Once you know that, hopefully your search will be easier!
Update, since I needed to refer back to this again - this hold true for nginx too - /var/log/nginx/error.log
is your friend in that case!
For those using Passenger:
• Navigate to root of your project.
• run bundle exec rake secret RAILS_ENV=production
• Copy the output and then run sudo nano config/secrets.yml
• Under production
, replace the value of the secret_key_base
with the recently copied rake secret.
• press CNTRL+X
, then press y
, then hit enter
.
• run passenger-config restart-app
and select the app you wish to restart.
