Project Management

  • Subversion - centralized version control for programming projects)
  • Trac - web-based code viewer, bug tracker, and ticketing system
  • Redmine - web-based code viewer, bug tracker, and ticketing system


Subversion (SVN) uses a centralized model to manage software projects. Collaborators check the source code out from the repository to their local development environments, make changes, then check code back in.

The repository can be on the local machine or a remote server, as SVN supports several protocols (svn://, http:// using Apache's mod_dav_svn module, file://, etc)..


$ sudo aptitude install subversion

Configure Apache:

Create a New Project

On The Server

Create the project skeleton (the name isn't important, it is only a folder in the file system):

$ sudo mkdir /tmp/myproject
$ sudo mkdir /tmp/myproject/{branches,tags,trunk}

Create the SVN repository, :

$ sudo mkdir /mnt/repositories/myproject
$ sudo svnadmin create /mnt/repositories/myproject

Import the initial project skeleton:

$ svn import /tmp/myproject/ file:///mnt/repositories/myproject/ -m "Initial import of project skeleton"

Clean up temp files and repository permissions. The repository needs www-data permissions because Apache will be serving our repository for us:

$ sudo rm -rf /tmp/myproject
$ sudo find /mnt/repositories/myproject/ -type f -exec chmod 660 {} \;
$ sudo find /mnt/repositories/myproject/ -type d -exec chmod 2770 {} \;
$ sudo chown -R root.www-data /mnt/repositories/myproject/

Tell Apache to use /svn/myproject URLs with the dav_svn module, /etc/apache2/conf.d/svn.conf:

<Location /svn/myproject>
    DAV svn 
    SVNPath /mnt/repositories/myproject
    AuthzSVNAccessFile /mnt/repositories/authz_svn_access

    AuthName "Microsoft Active Directory Authentication"
    AuthType Basic

    PerlAuthenHandler Apache2::AuthenMSAD
    PerlSetVar MSADDomain
    PerlSetVar MSADServer

    # require any valid AD user to access the repo via Apache,
    # then use fine-grained controls in the AuthzSVNAccessFile
    # above. See:
    require valid-user

    # Or, use specific (but dumb) controls here in the Apache
    # config file instead of the AuthzSVNAccessFile above.
    #require user aorth akihara

Gracefully restart Apache to enable the changes:

$ sudo apache2ctl graceful

On The Client

Check out the development branch ("trunk") to a local folder ("myproject"):

$ cd code/
$ svn co --username=aorth myproject

Import your existing code base ("mycode") into the project:

$ cd myproject
$ cp -R /home/aorth/mycode/* .
$ svn add *
$ svn commit -m "Initial import of codebase"

Ignoring Files and Folders

Sometimes you need to ignore certain files/folders (logs, temp files, etc) so that SVN doesn't try to commit those changes when it finds new files. For example: ignore everything in our project's tmp folder:

$ svn propedit svn:ignore tmp/

And then place a single "*" in the text editor to ignore everything in the tmp folder. Otherwise, you can do something like "*.log" to ignore all log files.

Tagging Releases

From trunk

$ cd myproject/
$ svn copy .

Switch a working copy to a certain release:

$ svn sw


Create a new Trac project:

$ sudo trac-admin /var/lib/trac/myproject initenv

Change the permissions so the Apache user can manage the Trac environment:

$ sudo chown -R www-data:www-data /var/lib/trac/myproject

Configure Apache to use Python for '/trac' URLs. Put settings in a new configuration file, /etc/apache2/conf.d/trac.conf:

<Location /trac>
     SetHandler mod_python
     PythonHandler trac.web.modpython_frontend
     PythonOption TracEnvParentDir /var/lib/trac
     PythonOption TracUriRoot /trac

The TracEnvParentDir option tells it to allow access to all Trac instances in the specified directory.

Add Active Directory support for login URLs:

<Location /trac/myproject/login>
   AuthName "Microsoft Active Directory Authentication"
   AuthType Basic
   PerlAuthenHandler Apache2::AuthenMSAD
   PerlSetVar MSADDomain
   PerlSetVar MSADServer
   #require valid-user
   require user aorth akihara jmagochi

This will tie Active Directory authentication into the login system for Trac. We use the same scheme for SVN too, so users will be able to log in as the same user they are submitting code as.

Add a user as an admin in a particular Trac project:

$ sudo trac-admin /var/lib/trac/myproject permission add aorth TRAC_ADMIN

Resync Trac/SVN

If your Trac gets out of sync with your SVN repository you will have to resync them:

$ sudo trac-admin /var/lib/trac/myproject resync

Install dependencies


# aptitude install build-essential rake ruby1.8 ruby1.8-dev irb1.8 rdoc1.8 zlib1g-dev libopenssl-ruby1.8 libzlib-ruby libssl-dev rubygems1.8

Download ruby gems

Problems I faced:

  • DNS is screwed up for and
  • has old versions of some gems (rails!)

You SHOULD be able to gem install the modules, but I downloaded them all manually and installed manually. It turns out it was a DNS issue, and I had to add some entries to the machine's /etc/hosts file:

Don't ask. I guess they are using the "cloud" and Amazon to host the files. I found these IPs from doing DNS queries outside ILRI.

$ wget
$ wget
$ wget
$ wget
$ wget
$ wget

Install gems

Rake, for building gems:

# gem install rake-0.8.3.gem

Make sure you can execute the rake binary:

# cd /usr/local/bin/
# ln -s /var/lib/gems/1.8/bin/rake

Continue installing gems:

# gem install rack-1.0.1.gem
# gem install fastthread-1.0.7.gem
# gem install mysql-2.8.1.gem
# gem install sqlite3-ruby-1.3.0.gem
# gem install rails-2.3.5.gem

Configure Redmine

Download and unzip the latest stable tarball:

$ wget
$ tar zxf redmine-0.9.4.tar.gz

Move redmine

Move redmine somewhere universal, outside of your home folder. We will configure Apache to serve redmine from this location:

$ sudo mv redmine-0.9.4 /opt/
$ cd /opt/redmine-0.9.4

Configure the database

We can either use MySQL or SQLite. SQLite has less overhead, and I'm not sure if it's any slower so we'll use that.

Edit config/database.yml:

   adapter: sqlite3
   dbfile: db/redmine.db

Initialize the database

$ chmod 600 config/database.yml
$ rake rake generate_session_store
$ RAILS_ENV=production rake db:migrate
$ RAILS_ENV=production rake redmine:load_default_data

Test the server

Before we can use Redmine with Apache, we have to make sure the installation worked fine. Use the built-in webserver to test first:

$ script/server -e production

If you get an error about not finding ruby, make sure the ruby version in the script/server script is correct.

Navigate to http://ip:3000 to see Redmine working. The default username and password are "admin"

Configure Apache

Install Phusion Passenger

Phusion Passenger ("mod_rails") is an Apache module which allows Apache to run ruby code (like mod_perl, mod_php, etc).

Install the gem

# gem install passenger

Install the Apache module

Edit the invocation line of the passenger installer program to point to ruby1.8:

#!/usr/bin/env ruby1.8

Run the installer:

# /var/lib/gems/1.8/gems/passenger-2.2.14/bin/passenger-install-apache2-module

Configure Apache settings

Apache will serve Redmine via FastCGI using the included dispatch.fcgi script. This is much faster than using Webrick or regular CGI.

Configure mod_rail.conf

/etc/apache2/conf.d/mod_rails.conf/: <file>LoadModule passenger_module /var/lib/gems/1.8/gems/passenger-2.2.14/ext/apache2/ PassengerRoot /var/lib/gems/1.8/gems/passenger-2.2.14 PassengerRuby /usr/bin/ruby1.8</file> ==== Configure redmine.conf ==== /etc/apache2/conf.d/redmine.conf: <file>RailsBaseURI /redmine RailsEnv production <Directory "/var/www/redmine"> AllowOverride all Options -MultiViews #Options Indexes ExecCGI FollowSymLinks Order allow,deny Allow from all </Directory></file> Link the Redmine installation to the web document root; make sure to use the same name as in your Apache configuration: <code># ln -s /opt/redmine-0.9.4/public/ /var/www/redmine</code> ==== Fix dispatch.fcgi ==== Rename it and make sure its executable: <code>$ mv public/dispatch.fcgi.example public/dispatch.fcgi $ chmod 755 public/dispatch.fcgi</code> Edit the invocation line in the FastCGI script to make sure it points to your ruby version (ruby1.8), and that the dispatcher line is correct: <file>#!/usr/bin/env ruby1.8 … require "/var/lib/gems/1.8/gems/rails-2.3.5/lib/dispatcher.rb" …</file> ==== Restart Apache ==== <code># apache2ctl graceful</code> ==== Fix permissions ==== Change permissions so the web server can read/write important files/folders: <code>$ chown -R www-data:www-data /opt/redmine-0.9.4</code>
