Errata for Deploying Rails

#49836: The book is based on the idiom of using a shared directory and git repo but every example uses a puppet:// scheme rather than a file:// scheme implying a puppetmaster. This is a pretty blatant error and I'm surprised it made it to market in this condition--Robert Olivier

#51119: Hello,

running on Vagrant 1.1.2 MacOS 10.8.3, VB 4.2.10

According to the PDF:

"For forwarding the ssh port, we include the :auto option, which tells Vagrant that if the port isn’t available, it should search for another available port."

Therefor writing:

app_config.vm.forward_port 22, 2222, :auto => true
db_config.vm.forward_port 22, 2222, :auto => true

should result in:

[output]...
[db] Fixed port collision for 22 => 2222. Now on port 2200. [db] Fixed port collision for 22 => 2222. Now on port 2201.

But on my machine I got following error:

vm:

* Forwarded port '2222' (host port) is declared multiple times

Cheers,

#49553: The passenger installation process uses gem to install the passenger gem. With the box exactly as specified in the text (that is, ruby 1.9.3 compiled from source and installed in /usr/bin/local), this won’t work without sudo.

(whether that is a good setup or not is not really the issue, just highlighting the issue)--Thomas van der Pol

#50809: mem = capture("free -m | grep Mem").squeeze.split(' ')[1..-1]

should be

mem = capture("free -m | grep Mem").squeeze(' ').split(' ')[1..-1]

because

"123 444 566".squeeze => "123 4 56"--Petr Cervinka

#49951: About NRPE, the example plugin, which is check_ssh, doesn't work. I suppose it's check_user here (in fact, this plugin is using for this section's conclusion).--Delmaire

#50151: Vagrant::Config.run do |config| config.vm.define :mysql_master do |m|

Not sure why the VM here refer to lucid32 - thought we should be using at least for APP the lucid64_with_ruby193?--Tim Chambers

#50309: Fernando de Se1 May 25th, 2010 7:16 am Solo discrepo en una cosa: el digaarma de Gutenberg es correcto, pero no su argumento, ya que ha sido probado en culturas donde el sentido de la lectura es distinto a la occidental y funciona de igual manera, lo que hace del argumento de la lectura algo inve1lido. La justificacif3n a esto se encuentra en la proporcif3n e1urea y en el espiral que se crea al combinarla. De ahed su justificacif3n. Por el resto del articulo totalmente de acuerdo, y considero que la prueba y error sigue siendo el mejor me9todo para entender el comportamiento humano.--VYfdExejYtD
