Nginx and Mongrel cluster on debian

Nginx is a ‘small’ efficient http, load balancer server. More and more popular in Rails community, it’s a good front end for mongrel clusters. It’s seems to be a good replacement for apache, at least for the memory usage (on my test: 1 process use 1.3M against the more than 9M taken by 1 apache process). Benchmark on one single server are quite similar.

The process has been tested on debian 4.0r1 and should work on Ubuntu.

Installation

apt-get install nginx

or, if you want an up to date product:

1/ Prepare your system

apt-get install zlib1g-dev libgcrypt11-dev libpcre3-dev libssl-dev

2/ Download source

tar xzf nginx-0.6.12.tar.gz
cd nginx-0.6.12

3/ Compile it

./configure --pid-path=/usr/local/nginx/logs/nginx.pid \
    --sbin-path=/usr/local/sbin/nginx \
    --with-md5=/usr/lib \
    --with-sha1=/usr/lib \
    --with-http_ssl_module \
    --with-http_dav_module --prefix=/usr \
    --conf-path=/etc/nginx/nginx.conf \
    --pid-path=/var/run/nginx.pid \
    --lock-path=/var/run/nginx.lock \
    --error-log-path=/var/log/nginx/error.log \
    --http-log-path=/var/log/nginx/access.log 

make

sudo make install

Configuration

The following configuration is for 1 nginx server with load balancing 3 mongrel in cluster:

1/ Mongrel cluster configuration

gem install mongrel_cluster -y

cd /var/www/my-app-path/current/

configures 3 mongrel in cluster, in production mode, starting at port 5000 and listening on localhost

sudo mongrel_rails cluster::configure -e production \
    -p 5000 -N 3 -c /var/www/my-app-path/current/ -a 127.0.0.1 \
    --user www-data

mongrel_rails cluster::start

2/ Nginx

nano /etc/nginx.conf

Use the nginx.conf file from brainspl.at website, change the 2 or 4 (if you use ssl) references to the path of your application (/var/www/my-app-path/current/)

/etc/init.d/nginx start

All these information come from many website (thanks to all), I put them together for my own usage, hope it’s helpfull.

I really like more the apache proxy balancer, and mongrel cluster deploy.

I think you’re forgetting the ‘make ; sudo make install’ part???

Hmm, I don’t know what “start” does…

mongrel_rails cluster::start

works for me
