    33Tracd is a lightweight standalone Trac web server.
    44It can be used in a variety of situations, from a test or development server to a multiprocess setup behind another web server used as a load balancer.
    55
    6 == Pros ==
     6== Pros
    77
    88 * Fewer dependencies: You don't need to install apache or any other web-server.
     
    1010 * Automatic reloading: For development, Tracd can be used in ''auto_reload'' mode, which will automatically restart the server whenever you make a change to the code (in Trac itself or in a plugin).
    1111
    12 == Cons ==
     12== Cons
    1313
    1414 * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache httpd.
    1515 * No native HTTPS support: [http://www.rickk.com/sslwrap/ sslwrap] can be used instead,
    16    or [http://trac.edgewall.org/wiki/STunnelTracd stunnel -- a tutorial on how to use stunnel with tracd] or Apache with mod_proxy.

    2020A single project on port 8080. (http://localhost:8080/)
    21 {{{
     21{{{#!sh
    2222 $ tracd -p 8080 /path/to/project

    24 Stricly speaking this will make your Trac accessible to everybody from your network rather than ''localhost only''. To truly limit it use ''--hostname'' option.

    3535
    3636An alternative way to serve multiple projects is to specify a parent directory in which each subdirectory is a Trac project, using the `-e` option. The example above could be rewritten:
    37 {{{
     37{{{#!sh
    3838 $ tracd -p 8080 -e /path/to

    94 == Using Authentication ==
     93== Using Authentication
     94
     95Tracd allows you to run Trac without the need for Apache, but you can take advantage of Apache's password tools (`htpasswd` and `htdigest`) to easily create a password file in the proper format for tracd to use in authentication. (It is also possible to create the password file without `htpasswd` or `htdigest`; see below for alternatives)
     96
     97{{{#!div style="border: 1pt dotted; margin: 1em"
     98**Attention:** Make sure you place the generated password files on a filesystem which supports sub-second timestamps, as Trac will monitor their modified time and changes happening on a filesystem with too coarse-grained timestamp resolution (like `ext2` or `ext3` on Linux, or HFS+ on OSX).
     99}}}
    95100
    96101Tracd provides support for both Basic and Digest authentication. Digest is considered more secure. The examples below use Digest; to use Basic authentication, replace `--auth` with `--basic-auth` in the command line.
    97102
    98103The general format for using authentication is:
    99 {{{
     104{{{#!sh
    100105 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
    101106}}}
     
    113118Examples:
    114119
    115 {{{
     120{{{#!sh
    116121 $ tracd -p 8080 \
    117122   --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1
     
    119124
    120125Of course, the password file can be be shared so that it is used for more than one project:
    121 {{{
     126{{{#!sh
    122127 $ tracd -p 8080 \
    123128   --auth="project1,/path/to/passwordfile,mycompany.com" \
     
    127132
    128133Another way to share the password file is to specify "*" for the project name:
    129 {{{
     134{{{#!sh
    130135 $ tracd -p 8080 \
    131136   --auth="*,/path/to/users.htdigest,mycompany.com" \
     
    133138}}}

    135 === Basic Authorization: Using a htpasswd password file ===
     140=== Basic Authorization: Using a htpasswd password file
    136141This section describes how to use `tracd` with Apache .htpasswd files.
    137142
    138   Note: It is necessary (at least with Python 2.6) to install the fcrypt package in order to
    139   decode the htpasswd format.  Trac source code attempt an `import crypt` first, but there
    140   is no such package for Python 2.6.
     143  Note: On Windows It is necessary to install the fcrypt package in order to
     144  decode some htpasswd formats. Only `SHA-1` passwords (since Trac 1.0) work
     145  without this module.
    141146
    142147To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
    143 {{{
     148{{{#!sh
    144149 $ sudo htpasswd -c /path/to/env/.htpasswd username
    145150}}}
    146151then for additional users:
    147 {{{
     152{{{#!sh
    148153 $ sudo htpasswd /path/to/env/.htpasswd username2
    149154}}}
    150155
    151156Then to start `tracd` run something like this:
    152 {{{
    153  $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname
     157{{{#!sh
     158 $ tracd -p 8080 --basic-auth="project,/fullpath/environmentname/.htpasswd,realmname" /path/to/project
    154159}}}
    155160
    156161For example:
    157 {{{
    158  $ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv
     162{{{#!sh
     163 $ tracd -p 8080 --basic-auth="project,/srv/tracenv/testenv/.htpasswd,My Test Env" /path/to/project
    159164}}}
    160165''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
    161166
    162 === Digest authentication: Using a htdigest password file ===
     167=== Digest authentication: Using a htdigest password file
    163168
    164169If you have Apache available, you can use the htdigest command to generate the password file. Type 'htdigest' to get some usage instructions, or read [http://httpd.apache.org/docs/2.0/programs/htdigest.html this page] from the Apache manual to get precise instructions.  You'll be prompted for a password to enter for each user that you create.  For the name of the password file, you can use whatever you like, but if you use something like `users.htdigest` it will remind you what the file contains. As a suggestion, put it in your <projectname>/conf folder along with the [TracIni trac.ini] file.
    165170
    166 Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error.
    167 
    168 === Generating Passwords Without Apache ===
    169 
    170 Basic Authorization can be accomplished via this [http://aspirine.org/htpasswd_en.html online HTTP Password generator].  Copy the generated password-hash line to the .htpasswd file on your system. Note that Windows Python lacks the "crypt" module that is the default hash type for htpasswd ; Windows Python can grok MD5 password hashes just fine and you should use MD5.
    171 
    172 You can use this simple Python script to generate a '''digest''' password file:
    173 
    174 {{{
    175 #!python
    176 from optparse import OptionParser
    177 # The md5 module is deprecated in Python 2.5
    178 try:
    179     from hashlib import md5
    180 except ImportError:
    181     from md5 import md5
    182 realm = 'trac'
    183 
    184 # build the options
    185 usage = "usage: %prog [options]"
    186 parser = OptionParser(usage=usage)
    187 parser.add_option("-u", "--username",action="store", dest="username", type = "string",
    188                   help="the username for whom to generate a password")
    189 parser.add_option("-p", "--password",action="store", dest="password", type = "string",
    190                   help="the password to use")
    191 parser.add_option("-r", "--realm",action="store", dest="realm", type = "string",
    192                   help="the realm in which to create the digest")
    193 (options, args) = parser.parse_args()
    194 
    195 # check options
    196 if (options.username is None) or (options.password is None):
    197    parser.error("You must supply both the username and password")
    198 if (options.realm is not None):
    199    realm = options.realm
    200    
    201 # Generate the string to enter into the htdigest file
    202 kd = lambda x: md5(':'.join(x)).hexdigest()
    203 print ':'.join((options.username, realm, kd([options.username, realm, options.password])))
    204 }}}
    205 
    206 Note: If you use the above script you must set the realm in the `--auth` argument to '''`trac`'''. Example usage (assuming you saved the script as trac-digest.py):
    207 
    208 {{{
    209  $ python trac-digest.py -u username -p password >> c:\digest.txt
    210  $ tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name
     171Note that you can start tracd without the `--auth` argument, but if you click on the ''Login'' link you will get an error.
     172
     173=== Generating Passwords Without Apache
     174
     175Basic Authorization can be accomplished via this [http://aspirine.org/htpasswd_en.html online HTTP Password generator] which also supports `SHA-1`.  Copy the generated password-hash line to the .htpasswd file on your system. Note that Windows Python lacks the "crypt" module that is the default hash type for htpasswd. Windows Python can grok MD5 password hashes just fine and you should use MD5.
     176
     177Trac also provides `htpasswd` and `htdigest` scripts in `contrib`:
     178{{{#!sh
     179$ ./contrib/htpasswd.py -cb htpasswd user1 user1
     180$ ./contrib/htpasswd.py -b htpasswd user2 user2
     181}}}
     182
     183{{{#!sh
     184$ ./contrib/htdigest.py -cb htdigest trac user1 user1
     185$ ./contrib/htdigest.py -b htdigest trac user2 user2
    211186}}}
    212187
    213188==== Using `md5sum`
    214189It is possible to use `md5sum` utility to generate digest-password file:
    215 {{{
     190{{{#!sh

     236=== Serving static content
    260237
    261238If `tracd` is the only web server used for the project,
     
    268245Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file,
    269246the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
    270 which in turn can be written as `htdocs:software-0.1.tar.gz` (TracLinks syntax) or `[/<project_name>/chrome/site/software-0.1.tar.gz]` (relative link syntax).
    271 
    272  ''Support for `htdocs:` TracLinks syntax was added in version 0.10''
     247which in turn can be written as `htdocs:software-0.1.tar.gz` (TracLinks syntax) or `[/<project_name>/chrome/site/software-0.1.tar.gz]` (relative link syntax).

    274249=== Using tracd behind a proxy
     
    283258
    284259=== Authentication for tracd behind a proxy
    285 It is convenient to provide central external authentication to your tracd instances, instead of using {{{--basic-auth}}}. There is some discussion about this in #9206.
     260It is convenient to provide central external authentication to your tracd instances, instead of using `--basic-auth`. There is some discussion about this in [trac:#9206].
    286261
    287262Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap.
     
    289264First we bring tracd into Apache's location namespace.
    290265
    291 {{{
     266{{{#!apache

    293268        Require ldap-group cn=somegroup, ou=Groups,dc=domain.com
     
    300275
    301276Then we need a single file plugin to recognize HTTP_REMOTE_USER header as valid authentication source. HTTP headers like '''HTTP_FOO_BAR''' will get converted to '''Foo-Bar''' during processing. Name it something like '''remote-user-auth.py''' and drop it into '''proxified/plugins''' directory:
    302 {{{
    303 #!python
     277{{{#!python
    304278from trac.core import *
    305279from trac.config import BoolOption
     
    322296
    323297Add this new parameter to your TracIni:

     308}}}
     309
     310Note that if you want to install this plugin for all projects, you have to put it in your [TracPlugins#Plugindiscovery global plugins_dir] and enable it in your global trac.ini.
     311
     312Global config (e.g. `/srv/trac/conf/trac.ini`):
