The problem with HHVM is it doesn't show much error, You have to keep watching the HHVM or Laravel error logs.

You'll want to pay close attention to your error logs. HHVM doesn't report errors to the browser by default.

Check the HHVM logs!

$ tail -n 50 -f /var/log/hhvm/error.log

Check your Laravel logs!

$ tail -n 50 -f /path/to/laravel/app/storage/logs/laravel.log

config reference

Create a file /etc/nginx/hhvm.conf if it doesn't exist yet. Insert the ff:

location ~ \.(hh|php)$ {
    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;
}

Then include it on your nginx virtual host config.
eg. /etc/nginx/sites-available/laravel

Now add this for Laravel, edit as needed:

server {
    listen 80 default_server;

    root /vagrant/laravel/public;
    index index.html index.htm index.php;

    server_name localhost;

    access_log /var/log/nginx/localhost.laravel-access.log;
    error_log  /var/log/nginx/locahost.laravel-error.log error;

    charset utf-8;

    location / {
        try_files \$uri \$uri/ /index.php?\$query_string;
    }

    location = /favicon.ico { log_not_found off; access_log off; }
    location = /robots.txt  { log_not_found off; access_log off; }

    error_page 404 /index.php;      

    include hhvm.conf;  # INCLUDE HHVM HERE

    # Deny .htaccess file access
    location ~ /\.ht {
        deny all;
    }
}

Then reload Nginx:

$ sudo service nginx reload

Since the X-Powered-By header is set by HHVM I assume your NGINX is configured correct. A 500 error mostly comes from a syntax error or an exception thrown in your application. Maybe your fastcgi settings in NGINX are still wrong. What's inside the location *\\.php block?

Try for a less error-prone setup and run php artisan serve to locally host your project.

Answer 3

You can modify Laravel's handle exception class to display the errors while HHVM is being used.

I have tested this and It works well on Laravel 5.2/5.3 on Homestead with HHVM.
