Trac

Trac is an open-source Issue Tracking System.

Trac Installation

$ sudo apt-get install trac libapache2-mod-python 

Installation of the Dependences

-To set up and use trac,

1. Trac project directory should be created.
2. Trac project directory info should be added to apache2 sites-enabled,
3. Database table for it should be created,

Create Project Directory

-To set up a trac project, create a directory for the project.

$ sudo mkdir /opt/trac 
$ sudo chown www-data:www-data /opt/trac 

-Create available site info for trac

$ cd /etc/apache2/sites-available 
$ sudo vim trac

Add Project Info to Apache

-Add the following lines

 <Location /trac>
   SetHandler mod_python
   PythonInterpreter main_interpreter
   PythonHandler trac.web.modpython_frontend
   PythonOption TracEnvParentDir /opt/trac
   PythonOption TracUriRoot /trac

1. PythonOption PYTHON_EGG_CACHE /tmp

   SetEnv PYTHON_EGG_CACHE /tmp
 </Location>

 <LocationMatch "/trac/[^/]+/login">
   AuthType Basic
   AuthName "Trac"
   AuthUserFile /etc/subversion/.passwd
   Require valid-user
 </LocationMatch>

-If PythonOption PYTHON_EGG_CACHE /tmp does not work and the following errors are displayed, use SetEnv PYTHON_EGG_CACHE /tmp instead.

...

ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

  [Errno 13] Permission denied: '/var/www/.python-eggs'

The Python egg cache directory is currently set to:

  /var/www/.python-eggs

Perhaps your account does not have write access to this directory?  You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.

-Enable it and reload apache2 config or restart it.

$ sudo a2ensite trac
$ sudo /etc/init.d/apache2 reload
or
$ sudo /etc/init.d/apache2 restart

Create and Setup Database Table

-Create database table for trac.

CREATE DATABASE trac DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;

-Check if its character set is correct

mysql> USE trac;
Database changed
mysql> SHOW VARIABLES LIKE '%character%';
+--------------------------+--------------------
| Variable_name            | Value
+--------------------------+--------------------
| character_set_client     | cp1251
| character_set_connection | cp1251
| character_set_database   | utf8
| character_set_filesystem | binary
| character_set_results    | cp1251
| character_set_server     | utf8
| character_set_system     | utf8
| character_sets_dir       | C:\DevServer\Instal
+--------------------------+--------------------
8 rows in set (0.00 sec)

-Allocate the admin user of trac database table.

GRANT ALL ON trac.* TO 'trac'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;

-The connection string is

mysql://trac:password@localhost/trac

Project Environment Initialisation

-Now initialise project.

$ sudo trac-admin /opt/trac/project initenv
Creating a new Trac environment at /opt/trac/project                   

Trac will first ask a few questions about your environment 
in order to initalize and prepare the project database.    

 Please enter the name of your project.
 This name will be used in page titles and descriptions.

Project Name [My Project]> My Project

 Please specify the connection string for the database to use.
 By default, a local SQLite database is created in the environment 
 directory. It is also possible to use an already existing         
 PostgreSQL database (check the Trac documentation for the exact   
 connection string syntax).                                        

Database connection string [sqlite:db/trac.db]> mysql://trac:password@localhost/trac

 Please specify the type of version control system,
 By default, it will be svn.                       

 If you don't want to use Trac with version control integration, 
 choose the default here and don't specify a repository directory. 
 in the next question.                                             

Repository type [svn]> svn

 Please specify the absolute path to the version control 
 repository, or leave it blank to use Trac without a repository.
 You can also set the repository location later.                

Path to repository [/path/to/repos]> /opt/svn/myproject

---------------------------------------------------------------------
Project environment for 'My Project' created.

You may now configure the environment by editing the file:

  /opt/trac/project/conf/trac.ini

If you'd like to take this new project environment for a test drive,
try running the Trac standalone web server `tracd`:

  tracd --port 8000 /opt/trac/project

Then point your browser to http://localhost:8000/project.
There you can also browse the documentation for your installed
version of Trac, including information on further setup (such as
deploying Trac to a real web server).

The latest documentation can also always be found on the project
website:

  http://trac.edgewall.org/

Congratulations!

-Set the permission.

$ sudo chown -R www-data:www-data /opt/trac 

Plugin Installation

There are numerous plug-ins available for Trac.

WebAdmin

WebAdmin is web user interface to administrate trac.

Installation

-Install the trac:WebAdmin plug-in.

#sudo svn export http://svn.edgewall.com/repos/trac/sandbox/webadmin/
$ sudo easy_install http://svn.edgewall.com/repos/trac/sandbox/webadmin/ 

-add TRAC_ADMIN permission to the user 'admin' in the project.

$ sudo trac-admin /opt/trac/project/ permission add admin TRAC_ADMIN 

Configuration

-add below to trac.ini (It is probably only for version 0.10. It has not been checked for 0.9)

==========================
[components]
webadmin.* = enabled
==========================

AccountManagerPlugin

-To make managing trac account easy, install account manager plug-in.

Install

-First make sure you've installed setuptools. $ sudo apt-get install python-setuptools

Then you can install the plugin using the easy_install application.

Note: Windows users will need to add easy_install to their PATH.

For Trac 0.9:

$ sudo easy_install http://trac-hacks.org/svn/accountmanagerplugin/0.9

For Trac 0.10:

Then install this plugin:

$ sudo easy_install http://trac-hacks.org/svn/accountmanagerplugin/0.10

For Trac 0.11: (and check #899 patch)

$ sudo easy_install http://trac-hacks.org/svn/accountmanagerplugin/trunk

Configuration

1. First, access Trac and log in with admin ID.
2. Go to Admin menu and configure Accounts module including set up the location of .htpasswd or .htdigest file.
3. Add the following lines to trac.ini file in the trac_project/conf directory

-Not necessary for 0.11 trac.ini

-or

[account-manager]
htdigest_realm = tectra_trac
password_file = /opt/trac/project/conf/users.htpasswd

-comment out the authentication info of trac in the available sites (/etc/apache2/sites-available/trac).

#  <LocationMatch "/trac/[^/]+/login">
#    AuthType Basic
