GitBlit at Nginx Issue on Pushing

I recently bumped into a problem with Gitblit which is deployed on a Jetty instance at my public virtual machine. I got some errors when pushing a change to my repository. It says "File too large to upload". This is error 413 and I first suspected Jetty but I have found out that the issue in on Nginx. It's not actually an issue but I just need to do some tweaking with my Nginx installation so I won't get the error anymore.

Client Max Body Size (client_max_body_size)

I don't know the exact default value of client_max_body_size but this parameter when set to a very high value will allow an upload not more that to that set value.

http {

        ##

        #include /etc/nginx/naxsi_core.rules;

        ##

        # nginx-passenger config

        ##

        # Uncomment it if you installed nginx-passenger

        ##

        #passenger_root /usr;

        #passenger_ruby /usr/bin/ruby;

        client_max_body_size 300M;

        ##

        # Virtual Host Configs

        ##

        include /etc/nginx/conf.d/*.conf;

        include /etc/nginx/sites-enabled/*;

}

When I set about 300M to my Nginx's client_max_body_size, I don't get the error 413 anymore. 

That's all!
