Lately more and more I catch myself on entering
cd .
This is needed if You have open Yours console on a path that changes via linking or mounting, using “cd .” allows very fast switch to the new location that You should be using.
Just short message:
Please follow it to help stop patents in EU
In previous steps we have configured ruby and apache, now time to get development environment, there is wide range of tools but we will use Netbeans as it is … quite good.
So on beginning please download Netbeans, please go to it’s download site and get “C/C++” or “PHP” version – they are smaller from the ruby version, we need to update the environment after download so we would download many components again.
After download run the Netbeans installation, it is very simple so just follow the on screen instructions. When Netbeans is installed please run it and go to Tools Menu -> Plugins, there select available plugins and select:
Do not install “Glasfish” or “JRuby” this is needed only for JRuby development which is not production ready, as some people think.
Additionally to installation You can perform update of the installed plugins in the Updates tab, after update and installation Netbeans will ask You to do restart to activate newly installed plugins, please follow it’s instructions.
When we have installed required plugins we can check that Netbeans sees our ruby installation, go to Tools Menu -> Ruby Platforms, here you will see yours ruby installations and it’s configuration, If you do not see any platform go threw the wizard under button Add Platform.
This is the development environmnet, in next part we will start a new project with it.
In previous article I have described how to setup postgress for development, now is time to continue with the environment. At the beginning we need:
So installation of required system packages:
emerge -qDNu ruby rubygems apache jdk
/etc/init.d/apache2 start
Install ruby gems that will be needed shortly:
UPDATE: 2009.01.26 added postgres
gem install rails capistrano capistrano-ext passenger postgres
Now we need to integrate passenger into apache – please run:
passenger-install-apache2-module
UPDATED 2009-02-06:
The installation should go without nay problems (If You followed all instructions), at the end You will be asked to modify apache configuration file – few Lines of the output – starting with LoadModule, PassengerRoot and PassengerRuby – should be copied to new apache configuration file, easiest way is to use this commands:
echo “LoadModule passenger_module /usr/lib64/ruby/gems/1.8/gems/passenger-2.0.6/ext/apache2/mod_passenger.so” > /etc/apache2/vhosts.d/01_passenger.conf
echo “PassengerRoot /usr/lib64/ruby/gems/1.8/gems/passenger-2.0.6” >> /etc/apache2/vhosts.d/01_passenger.conf
echo “PassengerRuby /usr/bin/ruby18” >> /etc/apache2/vhosts.d/01_passenger.conf
Some of the lines may differ from the output form yours passenger so please use Yours as it is better for you.
In next part we will continue with development environment.
Time to start some development, for next project I have decided to use (and learn) Ruby on Rails (RoR).
Many persons use mysql to develop rails apps, as it is easy to setup and use.
But postgresql has more futures then mysql, one of them is known to be used by current RoR, It is transactional DDL update, in Rails world it is called transactionall migrations.
So this is what I had to do to get it working on my gentoo box:
emerge postgresql-server
emerge postgresql-server –config
/etc/init.d/postgresql-8.3 start
su – postgres -c createuser mpapis
# or you could use: sudo -u postgres createuser mpapis
In the listing i have used settings from my computer, /etc/init.d/postgresql-8.3 can be any other name starting with postgres, replace mpapis with your user name.
After running those commands You are able to run psql from yours account, from now on You can run following commands to menage Yours postgresql database:
This knowledge should be enough to continue with rails, but this comes in next days.
