     1= Tracd = 
     2 
     3Tracd is a lightweight standalone Trac web server. 
     4It 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. 
     5 
     6== Pros == 
     7 
     8 * Fewer dependencies: You don't need to install apache or any other web-server. 
     9 * Fast: Should be almost as fast as the [wiki:TracModPython mod_python] version (and much faster than the [wiki:TracCgi CGI]), even more so since version 0.12 where the HTTP/1.1 version of the protocol is enabled by default 
     10 * 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). 
     11 
     12== Cons == 
     13 
     14 * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache httpd. 
     15 * 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. 
     17 
     18== Usage examples == 
     19 
     20A single project on port 8080. (http://localhost:8080/) 
     21{{{ 
     22 $ tracd -p 8080 /path/to/project 
     23}}} 
     24Stricly speaking this will make your Trac accessible to everybody from your network rather than ''localhost only''. To truly limit it use ''--hostname'' option. 
     25{{{ 
     26 $ tracd --hostname=localhost -p 8080 /path/to/project 
     27}}} 
     28With more than one project. (http://localhost:8080/project1/ and http://localhost:8080/project2/) 
     29{{{ 
     30 $ tracd -p 8080 /path/to/project1 /path/to/project2 
     31}}} 
     32 
     33You can't have the last portion of the path identical between the projects since Trac uses that name to keep the URLs of the 
     34different projects unique. So if you use `/project1/path/to` and `/project2/path/to`, you will only see the second project. 
     35 
     36An 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{{{ 
     38 $ tracd -p 8080 -e /path/to 
     39}}} 
     40 
     41To exit the server on Windows, be sure to use {{{CTRL-BREAK}}} -- using {{{CTRL-C}}} will leave a Python process running in the background. 
     42 
     43== Installing as a Windows Service == 
     44 
     45=== Option 1 === 
     46To install as a Windows service, get the [http://www.google.com/search?q=srvany.exe SRVANY] utility and run: 
     47{{{ 
     48 C:\path\to\instsrv.exe tracd C:\path\to\srvany.exe 
     49 reg add HKLM\SYSTEM\CurrentControlSet\Services\tracd\Parameters /v Application /d "\"C:\path\to\python.exe\" \"C:\path\to\python\scripts\tracd-script.py\" <your tracd parameters>" 
     50 net start tracd 
     51}}} 
     52 
     53'''DO NOT''' use {{{tracd.exe}}}.  Instead register {{{python.exe}}} directly with {{{tracd-script.py}}} as a parameter.  If you use {{{tracd.exe}}}, it will spawn the python process without SRVANY's knowledge.  This python process will survive a {{{net stop tracd}}}. 
     54 
     55If you want tracd to start automatically when you boot Windows, do: 
     56{{{ 
     57 sc config tracd start= auto 
     58}}} 
     59 
     60The spacing here is important. 
     61 
     62{{{#!div 
     63Once the service is installed, it might be simpler to run the Registry Editor rather than use the `reg add` command documented above.  Navigate to:[[BR]] 
     64`HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tracd\Parameters` 
     65 
     66Three (string) parameters are provided: 
     67||!AppDirectory ||C:\Python26\ || 
     68||Application ||python.exe || 
     69||!AppParameters ||scripts\tracd-script.py -p 8080 ... || 
     70 
     71Note that, if the !AppDirectory is set as above, the paths of the executable ''and'' of the script name and parameter values are relative to the directory.  This makes updating Python a little simpler because the change can be limited, here, to a single point. 
     72(This is true for the path to the .htpasswd file, as well, despite the documentation calling out the /full/path/to/htpasswd; however, you may not wish to store that file under the Python directory.) 
     73}}} 
     74 
     75For Windows 7 User, srvany.exe may not be an option, so you can use [http://www.google.com/search?q=winserv.exe WINSERV] utility and run: 
     76{{{ 
     77"C:\path\to\winserv.exe" install tracd -displayname "tracd" -start auto "C:\path\to\python.exe" c:\path\to\python\scripts\tracd-script.py <your tracd parameters>" 
     78 
     79net start tracd 
     80}}} 
     81 
     82=== Option 2 === 
     83 
     84Use [http://trac-hacks.org/wiki/WindowsServiceScript WindowsServiceScript], available at [http://trac-hacks.org/ Trac Hacks]. Installs, removes, starts, stops, etc. your Trac service. 
     85 
     86== Using Authentication == 
     87 
     88Tracd 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. 
     89 
     90The general format for using authentication is: 
     91{{{ 
     92 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path 
     93}}} 
     94where: 
     95 * '''base_project_dir''': the base directory of the project specified as follows: 
     96   * when serving multiple projects: ''relative'' to the `project_path` 
     97   * when serving only a single project (`-s`): the name of the project directory 
     98 Don't use an absolute path here as this won't work. ''Note:'' This parameter is case-sensitive even for environments on Windows. 
     99 * '''password_file_path''': path to the password file 
     100 * '''realm''': the realm name (can be anything) 
     101 * '''project_path''': path of the project 
     102 
     103 * **`--auth`** in the above means use Digest authentication, replace `--auth` with `--basic-auth` if you want to use Basic auth.  Although Basic authentication does not require a "realm", the command parser does, so the second comma is required, followed directly by the closing quote for an empty realm name. 
     104 
     105Examples: 
     106 
     107{{{ 
     108 $ tracd -p 8080 \ 
     109   --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1 
     110}}} 
     111 
     112Of course, the password file can be be shared so that it is used for more than one project: 
     113{{{ 
     114 $ tracd -p 8080 \ 
     115   --auth="project1,/path/to/passwordfile,mycompany.com" \ 
     116   --auth="project2,/path/to/passwordfile,mycompany.com" \ 
     117   /path/to/project1 /path/to/project2 
     118}}} 
     119 
     120Another way to share the password file is to specify "*" for the project name: 
     121{{{ 
     122 $ tracd -p 8080 \ 
     123   --auth="*,/path/to/users.htdigest,mycompany.com" \ 
     124   /path/to/project1 /path/to/project2 
     125}}} 
     126 
     127=== Basic Authorization: Using a htpasswd password file === 
     128This section describes how to use `tracd` with Apache .htpasswd files. 
     129 
     130To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache): 
     131{{{ 
     132 $ sudo htpasswd -c /path/to/env/.htpasswd username 
     133}}} 
     134then for additional users: 
     135{{{ 
     136 $ sudo htpasswd /path/to/env/.htpasswd username2 
     137}}} 
     138 
     139Then to start `tracd` run something like this: 
     140{{{ 
     141 $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname 
     142}}} 
     143 
     144For example: 
     145{{{ 
     146 $ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv 
     147}}} 
     148''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD). 
     149 
     150=== Digest authentication: Using a htdigest password file === 
     151 
     152If 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. 
     153 
     154Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error. 
     155 
     156=== Generating Passwords Without Apache === 
     157 
     158Basic Authorization can be accomplished via this [http://www.4webhelp.net/us/password.php online HTTP Password generator].  Copy the generated password-hash line to the .htpasswd file on your system. 
     159 
     160You can use this simple Python script to generate a '''digest''' password file: 
     161 
     162{{{ 
     163#!python 
     164from optparse import OptionParser 
     165# The md5 module is deprecated in Python 2.5 
     166try: 
     167    from hashlib import md5 
     168except ImportError: 
     169    from md5 import md5 
     170realm = 'trac' 
     171 
     172# build the options 
     173usage = "usage: %prog [options]" 
     174parser = OptionParser(usage=usage) 
     175parser.add_option("-u", "--username",action="store", dest="username", type = "string", 
     176                  help="the username for whom to generate a password") 
     177parser.add_option("-p", "--password",action="store", dest="password", type = "string", 
     178                  help="the password to use") 
     179parser.add_option("-r", "--realm",action="store", dest="realm", type = "string", 
     180                  help="the realm in which to create the digest") 
     181(options, args) = parser.parse_args() 
     182 
     183# check options 
     184if (options.username is None) or (options.password is None): 
     185   parser.error("You must supply both the username and password") 
     186if (options.realm is not None): 
     187   realm = options.realm 
     188    
     189# Generate the string to enter into the htdigest file 
     190kd = lambda x: md5(':'.join(x)).hexdigest() 
     191print ':'.join((options.username, realm, kd([options.username, realm, options.password]))) 
     192}}} 
     193 
     194Note: 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): 
     195 
     196{{{ 
     197 $ python trac-digest.py -u username -p password >> c:\digest.txt 
     198 $ tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name 
     199}}} 
     200 
     201==== Using `md5sum` 
     202It is possible to use `md5sum` utility to generate digest-password file: 
     203{{{ 
     204 $ printf "${user}:trac:${password}" | md5sum - >>user.htdigest 
     205}}} 
     206and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'. 
     207 
     208== Reference == 
     209 
     210Here's the online help, as a reminder (`tracd --help`):

     234}}} 
     235 
     236== Tips == 
     237 
     238=== Serving static content === 
     239 
     240If `tracd` is the only web server used for the project,  
     241it can also be used to distribute static content  
     242(tarballs, Doxygen documentation, etc.) 
     243 
     244This static content should be put in the `$TRAC_ENV/htdocs` folder, 
     245and is accessed by URLs like `<project_URL>/chrome/site/...`. 
     246 
     247Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file, 
     248the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,  
     249which 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).  
     250 
     251 ''Support for `htdocs:` TracLinks syntax was added in version 0.10'' 
     252 
     253=== Using tracd behind a proxy 
     254 
     255In some situations when you choose to use tracd behind Apache or another web server. 
     256 
     257In this situation, you might experience issues with redirects, like being redirected to URLs with the wrong host or protocol. In this case (and only in this case), setting the `[trac] use_base_url_for_redirect` to `true` can help, as this will force Trac to use the value of `[trac] base_url` for doing the redirects. 
     258 
     259If you're using the AJP protocol to connect with `tracd` (which is possible if you have flup installed), then you might experience problems with double quoting. Consider adding the `--unquote` parameter. 
     260 
     261See also [trac:TracOnWindowsIisAjp], [trac:TracNginxRecipe]. 
     262 
     263=== Serving a different base path than / === 
     264Tracd supports serving projects with different base urls than /<project>. The parameter name to change this is 
     265{{{ 
     266 $ tracd --base-path=/some/path 
     267}}}
