Ubuntu Nginx/Laravel 500 Internal Server Error

So I found the answer from a little more searching around. This page ultimately lead me to the answer: nginx configuration for Laravel 4

What I had to do was change the default config in /etc/nginx/sites-available/ and just change location / {} and add location @rewrite. The full config file I have is below with most of the # commented lines out.

server {    listen   80; ## listen for ipv4; this line is default and implied    root /usr/share/nginx/www/DDbuddy/public;    index index.php index.html index.htm;    server_name localhost;    location @rewrite {            rewrite ^/(.*)$ /index.php?_url=/$1;        }    location / {        try_files $uri $uri/ @rewrite;    }    location /doc/ {        alias /usr/share/doc/;        autoindex on;        allow 127.0.0.1;        deny all;    }    error_page 404 /404.html;    error_page 500 502 503 504 /50x.html;    location = /50x.html {        root /usr/share/nginx/www;    }    location ~ \.php$ {        fastcgi_split_path_info ^(.+\.php)(/.+)$;        fastcgi_pass 127.0.0.1:9000;        fastcgi_index index.php;        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;        include fastcgi_params;    }    # deny access to .htaccess files, if Apache's document root    # concurs with nginx's one    #    #location ~ /\.ht {    #   deny all;    #}}
