I will gladly upgrade my ruby to 1.9.2 which is one of the rubies on which rails 3.0.0 is supoorted.

Check my ruby version:

~# ruby -v
ruby 1.9.1p378 (2010-01-10 revision 26273) [i686-linux]

HINT: Don’t do this as root, as the paths we are using are user path which are slightly different for root! (But do it with sufficient privileges)

Install rvm:

Following two recipes: http://rvm.beginrescueend.com/rvm/install/  |   http://beyondtc.wordpress.com/2010/04/06/installing-rvm-on-debian-lenny/

~# <em>bash < <(curl  http://rvm.beginrescueend.com/releases/rvm-install-latest) </em>

This give you some installation related output and an OS-specific readme. On a MAC you will have to add a lign at the bottom of your .bashrc or.bash_profile file depending on your setup. (my .bashrc was in etc/). Here I am working on my Server and so I get the notes for linux. Basically rvm requires git and curl. I do have those. You’ll get more instructions for using JRUBY, MRI & ree and IronRuby. I don’t care for now. Let’s go on and be shure rvm is the freshest version available:

~# rvm update
~# rvm reload

Now we need to need to edit our .bashrc to correctly load the rvm scripts:

If you havent done anything different you should already be in /home/<username>/

check if your .bashrc is where it is supposed to:

~# cat .bashrc

If it is there, edit it:

~# nano .bashrc

On debian you will find the following line:

[ -z "$PS1" ] && return

Comment the out and add the following at the end of the file:

if [[ -s /home/<YOUR-USERNAME>/.rvm/scripts/rvm ]]; then
 source /home/<YOUR-USERNAME>/.rvm/scripts/rvm
fi

now logout and in again…

To check your setup try this:

~# type rvm | head -n1
rvm is a function

If you see something different go over the instructions on http://rvm.beginrescueend.com/rvm/install/

Run

~# rvm notes

to install the dependencies for you OS.

You should be all set!

Installing a new ruby is as easy as:

rvm install ruby-1.9.2-p0

Check all rubies managed by rvm:

~# rvm list
rvm rubies

=> ruby-1.9.2-p0 [ i386 ]

current ruby:

~# ruby -v
ruby 1.9.1p378 (2010-01-10 revision 26273) [i686-linux]

Switch ruby

~# rvm 1.9.2

~# ruby -v
ruby 1.9.2p0 (2010-08-18 revision 29036) [i686-linux]

Now be aware, that each version of ruby has its own set of gems.

~# gem list

*** LOCAL GEMS ***

bundler (1.0.2)
rake (0.8.7)

That’s all we have. Now set the new default:

~# rvm --default 1.9.2

~# rvm list default
Default Ruby (for new shells)

 ruby-1.9.2-p0 [ i386 ]

I am strictly following the basic instructions here: http://www.capify.org/index.php/From_The_Beginning

However, I already have a populated db, so I am leaving out that part.

I end up with a very basic Capfile:

load 'deploy' if respond_to?(:namespace) # cap2 differentiator
Dir['vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }

load 'config/deploy' # remove this line to skip loading any of the default tasks

The deploy.rb file has all the magic:

set :application, "my_app"

set :scm, :git
set :repository,  "git@github.com:username/softwareclick.git"
set :scm_username, "username"
set :scm_passphrase, "Password!"

set :deploy_to, "/path_to_my_app"

set :server_name, "123.456.78.9"
server "123.456.78.9", :app, :web, :db, :primary => true

set :user, "root"
set :use_sudo, false

# If you are using Passenger mod_rails uncomment this:
# if you're still using the script/reapear helper you will need
# these http://github.com/rails/irs_process_scripts

namespace :deploy do
   task :start do ; end
   task :stop do ; end
   task :restart, :roles => :app, :except => { :no_release => true } do
     run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
   end
end

>> app.get(“/”)
ArgumentError: A key is required to write a cookie containing the session data. Use config.action_controller.session = { :key => “_myapp_session”, :secret => “some secret phrase” } in config/environment.rb

…you are a victim of missing cookie session storage information in your environment.rb.
1. Get a cool secret key:

rake secret

2. Throw this in your environment.rb

# A key is required to write a cookie containing the session data. 
  config.action_controller.session = { :key => "_appname_session", :secret => "the_secret_key_rake_gave_ya" }

Once you ran cap deploy:update (more about the steps to deployment later) you might find this in your output:

...

** [216.194.126.4 :: out] Usage: /usr/bin/git-checkout [-f] [-b <new_branch>] [-m] [<branch>] [<paths>...]
command finished
*** [deploy:update_code] rolling back
...

First remove the old version:

apt-get remove git-core git-svn git-doc

Then install the latest version (it’s 1.7.1 at the time of writing but check for yourself on http://git-scm.com/)

aptitude install build-essential gettext
wget http://kernel.org/pub/software/scm/git/git-1.7.1.tar.gz
tar xvzf git-1.7.1.tar.gz
cd git-1.7.1
./configure
make
make install

Since Rails 2.0 there is no more need for the respond_to block in your controller. Just name the view accordingly to conventions:

e.g: index.xml.builder (if you just create an rss feed go for index.rss.builder! google just requires the filename to end on xml, that’s why)

The only slightly wicked thing in this is the declaration of the google namespace (line 3) and the use of that namespace in the attributes.

xml.instruct! :xml, :version => "1.0", :encoding => "UTF-8"
  xml.rss(:version => '2.0', :"xmlns:g"=>"http://base.google.com/ns/1.0") do
    xml.channel do
      xml.title 'Software-Click_Products'
      xml.link 'http://www.software-click.com'
      xml.description 'Software-Click offers a broad range of software products.'
      xml.language "en_us"
      xml.ttl "40"
      xml.pubDate(Time.now.strftime("%a, %d %b %Y %H:%M:%S %Z"))
      @products.each do |product|
        xml.item do
          xml.description(product.desc_en)
          xml.g :id, "#{product.id}"
          xml.link(product.url)
          xml.g :price, "#{product.price}"
          xml.title(product.name)
          xml.g :brand, "#{product.vendor}"
          xml.g :imagelink, "#{product.box}"
          xml.g :product_type, "software > #{product.category_id}"
          xml.g :format, 'download'
          xml.g :condition, 'new'
       end
     end
  end
end

For completeness-sake this is the index – action in my controller (the limit is just for testing):

def index
 @products = Product.find(:all, :limit => 2)
end
<pre>

That is all that’s needed. And I thought it would be far more time consuming than that.
Loving Rails for that!

Create a sft user group

hostname:~# groupadd sftp-users

Create the user that will be added to that group

hostname:~# adduser sftp-misterx

Add the new user to the sftp group

hostname:~# adduser sftp-username sftp_users

# We installed open-ssh earlier, if you haven’t:

# apt-get install openssh-server

Hopefully you created a dump from the old Postgres DB which holds the structure and data. I was using the export feature of phpPgAdmin to get my dump. In order to get all structure and sequences you need to dump the entire db, not just the tables.

This is the basic command that did it for me:

postgres@hostname:/home/dumps$ psql swc_prod < /home/dumps/dump.sql

Please make sure you create the same user
and role on the new server as used in the dump befor you start the import.

So now, let's see what we got!
1. Show list of users for the postgres database:
postgres@hostname:/root$ psql -d dbname_prod
dbname_prod-# \du





Now list the tables:
dbname_prod-# \dt









# For those who hack: I have actually re-done
it with different names, users and settings.

#by default postgres listens on port 5432, there a ways to change that by manipulating postgres.conf. You would also have to mess with the rails activerecord postgres conector. So I would rather make sure that your server has port 5432 open for TCP/IP …

In my case, I decided for a Silverrack VPS with Debian pre-installed. What I ultimately aim for is a fast, stable and reasonably-easy-to-administrate server delivering an approx. 60K+ pages website. The choice of DB would be MySQL or Postgres. I definately want to use capistrano for deployment and might consider passenger if it makes sense in my situation.

I’ll try to be consistent with my code examples:

• Black, if the machine wants you to do something
• Blue if it just does stuff and talks about it
• Red if I type in something to tell the machine what to do.
• Italic and gray for my comments
  

Alright, here we go:

1. Login for the first time

* Fix use of prerelease gems.
* Gem.bin_path no longer escapes path with spaces. Bug #25935 and #26458.

Deprecation Notices:

* Bulk index update is no longer supported (the code currently remains, but not
the tests)
* Gem::manage_gems was removed in 1.3.3.
* Time::today was removed in 1.3.3.

Fixing the manage_gems Error

Now, when you try to do a “gem install” or anything usefull that has to do with “manage_gems” (see output when installing rubygems) You will get an error like this:

hostname:~# gem install rails –no-rdoc –no-ri

/usr/bin/gem:10: undefined method `manage_gems’ for Gem:Module (NoMethodError)

Uhhh, to be honest, I did not really look into the reasoning of deprecating ‘manage_gems’ or figure out my own solution. I just followed  Martin Videc:

hostname:~# mv /usr/bin/gem /usr/bin/gem-backup

hostname:~# ln -s /usr/bin/gem1.8 /usr/bin/gem

It did the job for me so now we can …. drum-roll …

Install Rails

hostname:~# gem install rails –no-rdoc –no-ri

So now it’s time to have coffee and call mum, take a walk and maybe kick back and have a good read. On my server it took so long … I almost got nervous and stopped it.

Ahhh there we go:

Install a WebServer

First a decision has to be made: which server suites my needs?

I personally need a fast and reliable solution, that is fairly easy to configure and makes deployment a snap.

Dealing with rails you can choose from mongrel, apache2, nginx and lighthttpd.

Nginx is probably the leanest and meanest among those, but seems to have a pretty basic documentation. Apache can easily become a brick in your throat. configuration is just nerve wrecking and performance is just ok, not great. Lighttpd seems to be highly performant, stable and scalable solution. However I was a bit overwhelmed with the options and decided to use mongrel. Mongrel is to my knowledge the standard use for rails websites and is pretty well documented. BUT: If you are lazy like me you want the easy & fast setup and deployment. As I mentioned earlier, I want to use capistrano in deployment. It has done a great job for me when I was running it with passenger and apache2 on a shared host. So imagine my delight, when I found out there is a nginx installation packaged in passenger, if you like. Now we are talking!

Install passenger with nginx

This is pretty much what this video tutorial does.

Welcome to the Phusion Passenger Nginx module installer, v2.2.11.

This installer will guide you through the entire installation process. It
shouldn’t take more than 5 minutes in total.

Here’s what you can expect from the installation process:

1. This installer will compile and install Nginx with Passenger support.
2. You’ll learn how to configure Passenger in Nginx.
3. You’ll learn how to deploy a Ruby on Rails application.

Don’t worry if anything goes wrong. This installer will advise you on how to
solve any problems.

Automatically download and install Nginx?

Nginx doesn’t support loadable modules such as some other web servers do,
so in order to install Nginx with Passenger support, it must be recompiled.

Do you want this installer to download, compile and install Nginx for you?

1. Yes: download, compile and install Nginx for me. (recommended)
The easiest way to get started. A stock Nginx 0.7.64 with Passenger
support, but with no other additional third party modules, will be
installed for you to a directory of your choice.

2. No: I want to customize my Nginx installation. (for advanced users)
Choose this if you want to compile Nginx with more third party modules
besides Passenger, or if you need to pass additional options to Nginx’s
‘configure’ script. This installer will  1) ask you for the location of
the Nginx source code,  2) run the ‘configure’ script according to your
instructions, and  3) run ‘make install’.

Whichever you choose, if you already have an existing Nginx configuration file,
then it will be preserved.

Enter your choice (1 or 2) or press Ctrl-C to abort: 1

Where do you want to install Nginx to?

Please specify a prefix directory [/opt/nginx]:

…

——————————————–

Nginx with Passenger support was successfully installed.

The Nginx configuration file (/opt/nginx/conf/nginx.conf)
must contain the correct configuration options in order for Phusion Passenger
to function correctly.

This installer has already modified the configuration file for you! The
following configuration snippet was inserted:

http {
…
passenger_root /usr/lib/ruby/gems/1.8/gems/passenger-2.2.11;
passenger_ruby /usr/bin/ruby1.8;
…
}

After you start Nginx, you are ready to deploy any number of Ruby on Rails
applications on Nginx.

Press ENTER to continue.

——————————————–

Deploying a Ruby on Rails application: an example

Suppose you have a Ruby on Rails application in /somewhere. Add a server block
to your Nginx configuration file, set its root to /somewhere/public, and set
‘passenger_enabled on’, like this:

server {
listen 80;
server_name www.yourhost.com;
root /somewhere/public;   # <— be sure to point to ‘public’!
passenger_enabled on;
}

And that’s it! You may also want to check the Users Guide for security and
optimization tips and other useful information:

right above the other server config:

—————-

server {
listen       80;
server_name  localhost;

#charset koi8-r;
#access_log  logs/host.access.log  main;
location / {
root   html;
index  index.html index.htm;
}

Hint: If you have an old apache2 installation running get rid of it with:

hostname:~# dpkg -l | grep apache # which apache module is installed?

hostname:~# locate apache #shows what is where

hostname:~# /etc/init.d/apache2 stop #shuts it down

hostname:~# apt-get remove apache2 #gets rid of it, add other packages if needed

Now let’s start Nginx:

hostname:~# /opt/nginx/sbin/nginx

When you open your browser and go to the hostname you specified in nginx.conf you should see something delivered by ngingx.

To smoothly start and restart nginx, we need a script in init.d I used this directive from http://wiki.rubyonrails.org/deployment/vps-setup-nginx-passenger:

wget railsgeek.com/vps/nginx -P /etc/init.d
$ chmod +x /etc/init.d/nginx
$ /etc/init.d/nginx start
