Phusion Passenger.

See separate page for Phusion Passenger. In 2.0 it supports Rack-based frameworks so you can use it with Merb.

If you want to run your merb app on a /prefix on your server, edit init.rb and add c[:path_prefix] = '/prefix' within the Merb::Config.use do |c| block.

merb -e production -c 4 --port 9000

# config/deploy.rb

Using Nginx

Once Nginx has been installed, the configuration for the merb application needs to be applied.

Configuring Nginx

This has been split up into the general configuration and the specific virtual host for the application. First, the general configuration as shown below:

In Debian

Make sure you have the community repo configured in your /etc/pacman.conf

Install Nginx

h3.Install Nginx

In debian

In Archlinux

merb -c 4 --port 9000

In debian

In Archlinux

pacman -S nginx

$ sudo apt-get install nginx

 
$ sudo apt-get install nginx 

Once Nginx has been installed, the configuration for the merb application needs to be applied. This has been split up into the general configuration and the specific virtual host for the application. First, the general configuration as shown below:

and then the specific virtual configuration file:

 # /etc/nginx/conf/vhosts/app.conf 

and then in the virtual configuration:

 
server { 
 listen xx.xx.xxx.xx:80; 
 
 client_max_body_size 50M; 
 
 server_name xx.xx.xxx.xx; 
 
 root /path/to/app/current;

  if (-f $request_filename) { 
   break; 
  } 
  if (-f $request_filename/index.html) { 
   rewrite (.*) $1/index.html break; 
  } 
 
  if (-f $request_filename.html) { 
   rewrite (.*) $1.html break; 
  } 
 
  if (!-f $request_filename) { 
   proxy_pass http://polling_server; 
   break; 
  }  }

 location = /500.html { 
  root /path/to/app/current; 
 } 
} 

# /etc/nginx/nginx.conf 

Configuring Nginx

Install Nginx

Edit the Nginx Configuration File:

 
# /etc/nginx/nginx.conf 
user  www-data www-data; #chowned this user/group 
worker_processes  4; 
 
error_log  /var/log/nginx/error.log; 
pid        /var/run/nginx.pid; 
 
events { 
    worker_connections  1024; 
}

    include       /etc/nginx/mime.types; 
    default_type  application/octet-stream; 
 
    access_log    /var/log/nginx/access.log; 
 
    sendfile        on;

    } 
 
    # virtual configs 
    include /etc/nginx/conf/vhosts/app.conf; 
} 
 

merb -c 4 --port 9000 will start four Mongrels on ports 9000, 9001, 9002 and 9003.

Configuring for a shared host

If you want to run your merb app on a /prefix on your server, edit init.rb and add c[:path_prefix] = ’/prefix’ within the Merb::Config.use do |c| block.

merb -c 4 --port 9000 will start four Mongrels on ports 9000, 9001, 9002 and 9003. You can use -a to direct Merb to use a different application server: merb -a thin -c 4 --port 9000

This can be done programatically with Capistrano:

Choosing An Application Server

• Due its being threaded, Mongrel is still the king as a general purpose application server.
• An evented server (Thin, Ebb, Evented Mongrel) is only a viable option for applications that have very fast response times for every action (i.e. an API that serves JSON).

Configuring for a shared host

If you want to run your merb app on a /prefix on your server, edit init.rb and add c[:path_prefix] = ’/prefix’ within the Merb::Config.use do |c| block.

Booting Your Production Application

merb -c 4 --port 9000 will start four Mongrels on ports 9000, 9001, 9002 and 9003. You can direct Merb to use a different application server with -a: merb -a thin -c 4 --port 9000
