Nginx with Ubuntu and Rails on Digital Ocean - ruby-on-rails

Question

I am trying to get nginx to work with a rails app, but nginx wont start after installation and changing its config file.
Here is the output its giving me:
nginx: [emerg] could not build the types_hash, you should increase either types_hash_max_size: 1024 or types_hash_bucket_size: 32
nginx: configuration file /etc/nginx/nginx.conf test failed
And here is my nginx.conf file:
# This is example contains the bare mininum to get nginx going with
# Unicorn or Rainbows! servers. Generally these configuration settings
# are applicable to other HTTP application servers (and not just Ruby
# ones), so if you have one working well for proxying another app
# server, feel free to continue using it.
#
# The only setting we feel strongly about is the fail_timeout=0
# directive in the "upstream" block. max_fails=0 also has the same
# effect as fail_timeout=0 for current versions of nginx and may be
# used in its place.
#
# Users are strongly encouraged to refer to nginx documentation for more
# details and search for other example configs.
# you generally only need one nginx worker unless you're serving
# large amounts of static files which require blocking disk reads
worker_processes 1;
# # drop privileges, root is needed on most systems for binding to port 80
# # (or anything < 1024). Capability-based security may be available for
# # your system and worth checking out so you won't need to be root to
# # start nginx to bind on 80
user nobody nogroup; # for systems with a "nogroup"
# user nobody nobody; # for systems with "nobody" as a group instead
# Feel free to change all paths to suite your needs here, of course

# clients, even with Rails 3.1 streaming because otherwise a slow
# client can become a bottleneck of Unicorn.

# in the response headers do disable/enable buffering on a

Answer 1

I made another droplet with digital ocean with nginx already installed and just looked at the nginx.conf file and they had this in there http section
types_hash_max_size 2048;
