For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.
Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon
with HyperThreading enabled, but it can work without problem on slower machines.
You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
This should help you get Sendmail installed with basic configuration on Ubuntu.
sudo apt-get install sendmail
/etc/hosts
file: nano /etc/hosts
127.0.0.1 localhost yourhostname
sudo sendmailconfig
sudo service apache2 restart
You don't have to be a slave to OS X! Here's a guide to a sane dual-booting setup with Ubuntu 12.10 on your shiny MacBook Air. This is written and tested for a MacBook Air 5,2 (Mid 2012), but likely works the same with any modern Macbook.
Install according to instructions at this URL:
rake db:create |
require 'active_record' | |
require 'fileutils' | |
namespace :db do | |
desc "loads database configuration in for other tasks to run" | |
task :load_config do | |
ActiveRecord::Base.configurations = db_conf | |
ActiveRecord::Base.establish_connection db_conf | |
end |
namespace :db do | |
require "sequel" | |
Sequel.extension :migration | |
DB = Sequel.connect(ENV['DATABASE_URL']) | |
desc "Prints current schema version" | |
task :version do | |
version = if DB.tables.include?(:schema_info) | |
DB[:schema_info].first[:version] | |
end || 0 |
In an earlier video we took a look at Rack to build incredibly lightweight web applications with Ruby. Rack's toolkit allowed us to quickly throw to get a working application, but we did have to put a little effort into it once we wanted to build something a little more complex.
Sometimes you want a fast and simple framework for building a simple web application. Perhaps you only need to respond to a handful of routes, or you want the response time for a small part of a bigger application to be lighting fast. The Sinatra framework is made for just these moments.
Today let's take a quick look at this framework and see how quickly we can build lightweight web applications.
To get started we first need to install the Sinatra gem:
gem install sinatra
