nginx is a high performance web and proxy server
Installing nginx is easy. Simply issue the following command from SSH:
sudo box install nginx
This command will install and configure nginx for your user. Generally we recommend installing this first, which is why it is at the top of the list of install choices during setup.
The default swizzin virtualhost resides at:
The swizzin virtualhost by default will import and store application proxy/location information in the directory
/etc/nginx/apps. You can place your custom configurations here if you want to add additional location blocks unmanged by swizzin. You can also place your configs in subdirectories of this directory. Try to avoid using names already in use by swizzin for your own apps.
swizzin also makes use of "upstream" configurations to handle proxying certain multi-user applications (i.e. Deluge, qBittorrent, etc). These upstreams may be found in
Finally, if you ever make any mistakes or changes to nginx and it stops working, the command
box upgrade nginx will wipe out your current configs and re-run all the nginx-related scripts for the applications you have currently installed. In essence, this will "fix" your broken nginx by resetting it to the state that swizzin expects it to be in. If you have made any modifications you wish to save, please back them up before running this command as it's considered destructive.
The holy grail command for troubleshooting nginx failures is
sudo nginx -t
This command will scan your current configuration and run syntax and sanity checks against it. If for any reason it finds an error in your configs,
nginx -t will tell you exactly where the issue is so you can rectify the error (perhaps it's a duplicate line or some other config issue you should google for).
nginx stores its logs in the
/var/log/nginx directory. In this directory you'll find both
access.log. If you are troubleshooting gateway/proxy issues, then
error.log will be your best bet. If for some reason you are trying to debug access controls then
access.log stores a log of every hit to the nginx server.
The application you are trying to reach is likely down (not running). Please ensure the application is in fact running. If it is running and the error persists, you likely have a port mismatch between where the application is bound to (application config) and where nginx expects this application to be at (application proxy config). If you rectify the port mismatch, and reload nginx/the application, the connection should be fixed.
If you have received this after installing swizzin and are attempting to access the panel, then you have not installed the panel. Install the panel with
box install panel. If you are receiving this on another endpoint other than the top level of your domain, then your username/password is incorrect.
