Now that you have everything set up, it is time to create a virtual host to run your website.

Create a new config file that holds your website detail:

sudo nano /etc/nginx/sites-available/my-site
and paste in the following snippet:

server {
        listen 80;
        listen [::]:80;
 
        root /var/www/html;
 
        # Add index.php to the list if you are using PHP
        index index.html index.htm;
 
        server_name mywebsite.com;
        include hhvm-with-fallback.conf;
 
        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }
 
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location @fallback {
        #       include snippets/fastcgi-php.conf;
        #
        #       # With php5-fpm:
               fastcgi_pass unix:/var/run/php5-fpm.sock;
               fastcgi_index index.php;
               include fastcgi_params;
        }
 
        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        location ~ /\.ht {
                deny all;
        }
}
You can change the server_name to point to your own domain and the root folder location where you want the files to be served.

HHVM has this bug of crashing occasionally without restarting itself; this will cause the website to fail with a 500 error. In this case, we will create a fallback system whereby PHP5-FPM will take over when HHVM fails. Notice the location @fallback block in the config snippet above? That is the callback when HHVM fails. To complete the equation, we still need to create the “hhvm-with-fallback.conf” file which is a modified version of the “hhvm.conf” file.

sudo nano /etc/nginx/hhvm-with-fallback.conf
Paste the following snippet:

location ~ \.(hh|php)$ {
    proxy_intercept_errors on;
    error_page 500 501 502 503 = @fallback;
 
    fastcgi_keep_conn on;
 
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include        fastcgi_params;
}
Save and exit the file.

Lastly, test Nginx settings with

sudo nginx -t
and if everything is fine, restart Nginx.

sudo service nginx restart
After that, you have completed the LEMH stack setup on your Linux server.
