Nginx won't start since Ubuntu upgrade (16.04)












5















I have recently upgraded my Ubuntu server to the 16.04 release. Since then I can't start the nginx service.



Results of service nginx restart :



Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.


What my system logs says (cat /var/log/syslog) :



May 20 17:03:53: Stopped A high performance web server and a reverse proxy server.

There is indeed no file at /usr/sbin/nginx, so I tried apt install nginx, but here's the result :

  • I had something similar happen for a different reason. I'm not sure how this happened, but overnight, possibly because of a restart that triggered an update, Apache was running and was blocking Nginx from running. If the above doesn't work, you may want to see if you have apache running too. In which case, stop the apache service, then try to start nginx.

  • I had something similar happen for a different reason. I'm not sure how this happened, but overnight, possibly because of a restart that triggered an update, Apache was running and was blocking Nginx from running. If the above doesn't work, you may want to see if you have apache running too. In which case, stop the apache service, then try to start nginx.

So you've got two things which are in conflict and have led it seems to the nginx binaries going away somehow: Xenial repository version, and the NGINX PPA. As the maintainer of both, allow me to explain the conflict.



In Xenial, we released 1.10.0 just after release as an update. This update pushed us to a 'stable' branch but didn't have dynamically-loadable modules built and made available. This was due to time but also build conflicts that arose during tests. We eventually got dynamic module support working, in Zesty.



In the PPA, we've always cloned directly from Debian. That means, we always had Debian's 'dynamic module' support, which conflicted with the Xenial packages and resulted in some installation and upgrade conflicts.





There's a small conflict here - you can't mix-and-match nginx-core (which is the default flavor installed for the nginx package in Ubuntu) and the PPAs, as it sometimes makes things disappearify. The problem here, then, is we need to remove the existing Ubuntu package and then install from the PPA only.



To resolve this, you'll first need to back up your nginx configurations you want to keep for your sites. That is, make a copy of your /etc/nginx/sites-available/ directory somewhere else (even in your user's home directory is fine, we just need a copy of the site configurations). As well, we'll need a backup of your website data, so copy that somewhere else as well (NOT in the standard docroot, so it doesn't get messed up).



Once you make the copy, you'll have to remove the existing nginx packages. This can be done with the following command:



sudo apt-get remove nginx nginx-common nginx-doc nginx-core nginx-full nginx-extras nginx-light


Once that is complete, run sudo apt-get update again just to make sure we have the most up to date version numberings.



Then, install nginx from the PPA - sudo apt-get install nginx nginx-full nginx-common should do this.



You should no longer be getting failed to start errors. Make sure your site configurations are still in place, and didn't get overwritten. If they did, restore from the backups we took earlier of the site config and the site data. Otherwise, you're all set.

So you've got two things which are in conflict and have led it seems to the nginx binaries going away somehow: Xenial repository version, and the NGINX PPA. As the maintainer of both, allow me to explain the conflict.



In Xenial, we released 1.10.0 just after release as an update. This update pushed us to a 'stable' branch but didn't have dynamically-loadable modules built and made available. This was due to time but also build conflicts that arose during tests. We eventually got dynamic module support working, in Zesty.



In the PPA, we've always cloned directly from Debian. That means, we always had Debian's 'dynamic module' support, which conflicted with the Xenial packages and resulted in some installation and upgrade conflicts.





There's a small conflict here - you can't mix-and-match nginx-core (which is the default flavor installed for the nginx package in Ubuntu) and the PPAs, as it sometimes makes things disappearify. The problem here, then, is we need to remove the existing Ubuntu package and then install from the PPA only.



To resolve this, you'll first need to back up your nginx configurations you want to keep for your sites. That is, make a copy of your /etc/nginx/sites-available/ directory somewhere else (even in your user's home directory is fine, we just need a copy of the site configurations). As well, we'll need a backup of your website data, so copy that somewhere else as well (NOT in the standard docroot, so it doesn't get messed up).



Once you make the copy, you'll have to remove the existing nginx packages. This can be done with the following command:



sudo apt-get remove nginx nginx-common nginx-doc nginx-core nginx-full nginx-extras nginx-light


Once that is complete, run sudo apt-get update again just to make sure we have the most up to date version numberings.



Then, install nginx from the PPA - sudo apt-get install nginx nginx-full nginx-common should do this.



You should no longer be getting failed to start errors. Make sure your site configurations are still in place, and didn't get overwritten. If they did, restore from the backups we took earlier of the site config and the site data. Otherwise, you're all set.
