502 Bad gateway / rails 4 / nginx / passenger 4.0.49 /

Question

I can’t find my mistake ... and how to fix it.

he seems to have 2 errors

I also feel that my server is not starting, I don’t know where to look for verification, but the restart.txt file in the tmp file is not cleared (even after chmod 777 tmp) Therefore, I think my server does not restart after my change.

I tried to create an index.html file in a public folder. And it works. index.html looks good

Answer 1

Did you try to install

 passenger_set_cgi_param SECRET_KEY_BASE "39d95ff31bba12f1ea6bf0f2e332fc7b4797679b04ce9d45deb155fdc090a57960ee3fae82383fa18015c9444f5828769ae896c5dbe32e0916da23b79304f7fc"; 

in your site settings?

Answer 2

Try deferring the secrets.yml file correctly:

 production: secret_key_base: <%= ENV["SECRET_KEY_BASE"] %> 

The error says that it cannot find this variable for production env.
