Nginx doesn’t work after reinstall

debiandebian-wheezynginxphusion-passenger

I really have no clue at all where to start looking for an answer to this: I followed the instructions here to set up nginx and passenger for debian. (sudo apt-get nginx-extras passenger) Everything worked fine. Then I tried to set up ssl:

  • created a server key and so on
  • copied /etc/nginx/sites-available/default and uncommented and edited the necessary lines
  • created a symbolic link in /etc/nginx/sites-enable
  • restarted nginx

Suddenly I couldn't connect to the server via firefox anymore. So I undid every above mentioned step – nothing. I uninstalled nginx-extras and passenger and manually removed every file and directory named '*nginx*' because I saw that the whole /etc/nginx/ directory still existed. I then installed everything again – still nothing.

Even when I thought it was completely removed ps waux | grep nginx produced this though:
USERNAME 3776 0.0 0.1 11292 928 pts/0 S+ 22:15 0:00 grep nginx

Any ideas?

Best Answer

I uninstalled nginx-extras and passenger and manually removed every file and directory named 'nginx' because I saw that the whole /etc/nginx/ directory still existed.

That's expected (and desirable). The package manager won't delete your config files in /etc.

Even when I thought it was completely removed ps waux | grep nginx produced this though: USERNAME 3776 0.0 0.1 11292 928 pts/0 S+ 22:15 0:00 grep nginx

Right. That grep is detecting the grep command itself in the process list, since it contains "nginx". I don't see anything in there that implies nginx is running.

Recommendations:

  1. Reinstall nginx-extras and passenger, re-doing the configuration in /etc/nginx that you deleted.
  2. Run sudo service nginx status to ensure it's still running. If not:
  3. Run sudo service nginx start or sudo service nginx restart and post any error messages it reports back.

Please post the (sanitized) the contents of your config files with your question. It helps a lot to know what configuration has been done, as I expect your problem is going to be fixed in those config files.
