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

Question

I can not find my error...and how to fix it.

it seem to have 2 errors

I also feel that my server does not start, I do not know where to look for check but The file restart.txt in tmp does not clear, (even after chmod 777 tmp) So I think my server does not restart after my change.

I tried to create an index.html file in the public folder. And it work. index.html appears well

cat /var/log/nginx/error.log

Did you try setting

passenger_set_cgi_param SECRET_KEY_BASE "39d95ff31bba12f1ea6bf0f2e332fc7b4797679b04ce9d45deb155fdc090a57960ee3fae82383fa18015c9444f5828769ae896c5dbe32e0916da23b79304f7fc";
