Nginx, Mongrel, Merb

Quick notes on installing and configuring nginx and running with existing mongrel and Merb app on my MacBookPro.

1) Download and install PCRE (if needed)
http://www.pcre.org/
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.8.tar.gz

$ ./configure
$ ./make
$ ./make install

2) Download and install nginx:
http://nginx.net/
The latest stable version is nginx-0.6.32, the change log.
http://sysoev.ru/nginx/nginx-0.6.32.tar.gz

$ ./configure
$ ./make
$ ./make install

# Edit nginx.conf file (/usr/local/nginx/conf/nginx.conf)
# Note - based on Ezra's blog post (see notes below)

          }
          rewrite (.*) $1.html last;
        }

        location ~ .html {

            proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        }

    }
}

4) Commands for starting and stopping nginx
start: sudo /usr/local/nginx/sbin/nginx
stop: sudo kill `cat /usr/local/nginx/logs/nginx.pid`

5) Start Mongrel cluster (I'm using 3 Mongrels):
$ merb -c 3
or
$ merb -p 4000 -c 3
