• How to install the Trac wiki ,Subversion and issue tracking system

    One of the wonderful wiki system i have ever seen is the Trac open source project ,you may have some problems during the installation process ,So i have written this document to facilitate the installation process as i can .
    This article is for Centos 5 – x86_64 :

    1. Add epel repository : 
      rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
    2. Install Mandatory Dependencies: 
      yum -y  install mysql mysql-server python setuptool babel docutils pytz  httpd mod_wsgi mod_python subversion mod_dav_svn mod_python mysql-python neon neon-devel python-devel swig MySQL-python
    3. Install Trac: 
      wget http://peak.telecommunity.com/dist/ez_setup.pypython  && ez_setup.py && easy_install Trac==0.12
    4. Create Trac & subversion directories : 
      mkdir -p /var/www/trac/project1 && mkdir -p /var/www/svn/svnrepos && mkdir -p /var/www/svn/auth && mkdir -p /var/www/svn/svnrepos/project1 && mkdir -p /var/www/trac/project1
    5. SVN configuration: 
      svnadmin create --fs-type fsfs /var/www/svn/svnrepos/project1

      svn mkdir -m  file:///var/www/svn/svnrepos/project1/branches file:///var/www/svn/svnrepos/project1/tags file:///var/www/svn/svnrepos/project1/trunkc
      chown -R apache:apache /var/www/svn/svnrepos/project1/

      htpasswd -cb /var/www/svn/auth/svn.htpasswd raafat Password
      vi /etc/httpd/conf.d/subversion.conf

      Add the following lines:

      LoadModule dav_svn_module     modules/mod_dav_svn.so
LoadModule authz_svn_module   modules/mod_authz_svn.so
<Location /svn>
 DAV svn
 SVNParentPath /var/www/svn/svnrepos/
 AuthType Basic
 AuthName "project1 Authintication "
 AuthUserFile /var/www/svn/auth/svn.htpasswd
 Require valid-user
 </Location>
      chown -R apache.apache /var/www/svn/svnrepos/project1
      /etc/init.d/httpd restart

      Now ,You can access SVN via http://server_ip/svn

    6. Trac configuration:

 trac-admin /var/www/trac/project1 initenv

      Follow the steps after ruining the previous command.

      chown -R apache.apache /var/www/trac/project1
      htpasswd -cb /var/www/trac/.htpasswd raafat Password

      Add the following lines to /etc/httpd/conf.d/trac.conf

      <Location />
 SetHandler mod_python
 PythonHandler trac.web.modpython_frontend
 # "/var/www/svn/foobar" is the folder you gave to trac-admin initenv earlier
 PythonOption TracEnv /var/www/trac/project1
 # "/trac" is the same as the Location above
 PythonOption TracUriRoot /
 # "/tmp" should be some writable temporary directory
 SetEnv PYTHON_EGG_CACHE /tmp
 # "trac" can be any string, but must be the same for all
 # Trac instances on the same Apache install
 PythonInterpreter trac
 #PythonInterpreter main_interpreter
 </Location>
 <Location />
 AuthType Basic
 AuthName "Trac Authintication"
 AuthUserFile /var/www/trac/.htpasswd
 Require valid-user
 </Location>
    7. To show subversion in Trac system :Add the following line to trac.ini config file located in <projectenv>/conf/trac.ini 
      [components]
 tracopt.versioncontrol.svn.* = enabled

      Restart Apache:

      /etc/init.d/httpd restart

    8. Now you have successfully installed Track with subversion.

    Bugs:

    You may got the following error as me 🙂 ,while restarting apache :

    Problem : ImportError: No module named trac
    Solution:cd /usr/lib/python2.4/site-packages;unzip Trac-0.12-py2.4.egg
    Note:change .egg file as you have on your system.

    I will show you how to authenticate from LDAP server and Active directory ASAP.
