SSL setup isn't required, but I'd recommend it.
user nginx; worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; charset utf-8; gzip on; gzip_types text/plain application/xml text/javascript; gzip_min_length 1000; index index.php index.html index.htm; # Rewrite all requests from HTTP to HTTPS server { listen 80; server_name tickets.mydomain.com; rewrite ^ https://tickets.mydomain.com permanent; } server { listen 443; server_name tickets.mydomain.com; ssl on; ssl_certificate /etc/nginx/certs/cert.pem; ssl_certificate_key /etc/nginx/certs/cert.key; keepalive_timeout 70; root /var/www/osticket; location / { try_files $uri $uri/ index.php; } location ~ \.php$ { fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; fastcgi_pass 127.0.0.1:8888; } } }
