ubuntu 11.10 install openshift client tools

• ruby stuff

    $ sudo aptitude install ruby
    $ sudo aptitude install rubygems
    $ sudo gem install json_pure
    $ sudo gem install rake
    $ sudo gem install rhc
  

• fix the error file mime-types-1.18.gemspec then re-install all gems needed

    #should be line 9, changed it to: s.date = %q{2012-03-21}
    $ sudo vim /var/lib/gems/1.8/specifications/mime-types-1.18.gemspec 
    $ sudo gem install json_pure
    $ sudo gem install rake
    $ sudo gem install rhc
  

###now play with openshift

1. apply a account on https://openshift.redhat.com/, get your email,password

    #create a domain(namespace)
    $ rhc domain create -n domain -l email  
    #create a app
    $ rhc app create -a appname -t python-2.6 -l email
    #now you will get folder named `appname`        
   

2. if your app is new app created int step 1,skip this step

    #create keys
    $ ssh-keygen -t rsa -f ~/.ssh/libra_id_rsa -C email  
    #add public key
    $ rhc sshkey add -i public_key_name -k ~/.ssh/libra_id_rsa.pub  -l email
    #edit your ssh config   
    $ cat ~/.ssh/config
    Host *.rhcloud.com
    IdentityFile ~/.ssh/libra_id_rsa 
   

3. show git url $ rhc domain status -l email

    $ rhc domain show -l email
    Git URL: ssh://some_random@appname-domain.rhcloud.com/~/git/api.git/
   

4. then you can ssh,make yourself at home

    $ssh some_random@appname-domain.rhcloud.com
   

5. git stuff

    #clone your app by git url or it's alreay created by step 1
    #modify setup.py
    $ cd appname
    #change install_requires=[''],use django,web.py,bottle or something
    $ vim setup.py 
    $ cd wsgi
    #use django web.py wsgi 
    #webpy example <https://github.com/ehazlett/openshift-webpy-example/blob/master/wsgi/application>
    $ vim application   
    #add and commit
    $ git push
   

6. python stuff,get your project home folder if want to use web framework's template

    def get_home_dir():
        try:
            dir1 = os.environ['OPENSHIFT_REPO_DIR']
            if dir1.endswith('/') == False:
                dir1 += '/'
            dir1 += 'wsgi/'
            return dir1
        except:
            return './'#shoud be /,not have permission
   

7. show log

    $rhc-tail-files -l email -a appname
