 v2 = Tracd = Tracd is a lightweight standalone Trac web server. In most cases it's easier to setup and runs faster than the [wiki:TracCgi CGI script]. Tracd is a lightweight standalone Trac web server. It 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. == Pros == * Fewer dependencies: You don't need to install apache or any other web-server. * Fast: Should be almost as fast as the [wiki:TracModPython mod_python] version (and much faster than the [wiki:TracCgi CGI]). * 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 * 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). == Cons == * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache HTTPD. * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache httpd. * No native HTTPS support: [http://www.rickk.com/sslwrap/ sslwrap] can be used instead, or [http://trac.edgewall.org/wiki/STunnelTracd stunnel -- a tutorial on how to use stunnel with tracd] or Apache with mod_proxy. To exit the server on Windows, be sure to use {{{CTRL-BREAK}}} -- using {{{CTRL-C}}} will leave a Python process running in the background. == Installing as a Windows Service == === Option 1 === To install as a Windows service, get the [http://www.google.com/search?q=srvany.exe SRVANY] utility and run: {{{ C:\path\to\instsrv.exe tracd C:\path\to\srvany.exe reg add HKLM\SYSTEM\CurrentControlSet\Services\tracd\Parameters /v Application /d "\"C:\path\to\python.exe\" \"C:\path\to\python\scripts\tracd-script.py\" " net start tracd }}} '''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}}}. If you want tracd to start automatically when you boot Windows, do: {{{ sc config tracd start= auto }}} The spacing here is important. {{{#!div Once 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]] HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tracd\Parameters Three (string) parameters are provided: ||!AppDirectory ||C:\Python26\ || ||Application ||python.exe || ||!AppParameters ||scripts\tracd-script.py -p 8080 ... || Note 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. (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.) }}} For 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: {{{ "C:\path\to\winserv.exe" install tracd -displayname "tracd" -start auto "C:\path\to\python.exe" c:\path\to\python\scripts\tracd-script.py " net start tracd }}} === Option 2 === Use [http://trac-hacks.org/wiki/WindowsServiceScript WindowsServiceScript], available at [http://trac-hacks.org/ Trac Hacks]. Installs, removes, starts, stops, etc. your Trac service. == Using Authentication == Using tracd with Apache .htpasswd files: To create a .htpasswd file using htpasswd: {{{ sudo htpasswd -c /path/to/env/.htpasswd username Tracd provides support for both Basic and Digest authentication. The default is to use Digest; to use Basic authentication, replace --auth with --basic-auth in the examples below. (You must still specify a dialogic "realm", which can be an empty string by trailing the BASICAUTH with a comma.) The general format for using authentication is: {{{ $tracd -p port --auth="base_project_dir,password_file_path,realm" project_path }}} where: * '''base_project_dir''': the base directory of the project specified as follows: * when serving multiple projects: ''relative'' to the project_path * when serving only a single project (-s): the name of the project directory Don't use an absolute path here as this won't work. ''Note:'' This parameter is case-sensitive even for environments on Windows. * '''password_file_path''': path to the password file * '''realm''': the realm name (can be anything) * '''project_path''': path of the project * **--auth** in the above means use Digest authentication, replace --auth with --basic-auth if you want to use Basic auth Examples: {{{$ tracd -p 8080 \ --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1 }}} Of course, the password file can be be shared so that it is used for more than one project: {{{ $tracd -p 8080 \ --auth="project1,/path/to/passwordfile,mycompany.com" \ --auth="project2,/path/to/passwordfile,mycompany.com" \ /path/to/project1 /path/to/project2 }}} Another way to share the password file is to specify "*" for the project name: {{{$ tracd -p 8080 \ --auth="*,/path/to/users.htdigest,mycompany.com" \ /path/to/project1 /path/to/project2 }}} === Using a htpasswd password file === This section describes how to use tracd with Apache .htpasswd files. To create a .htpasswd file use Apache's htpasswd command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache): {{{ $sudo htpasswd -c /path/to/env/.htpasswd username }}} then for additional users: {{{ sudo htpasswd /var/www/html/.htpasswd-users username2 }}} then for starting the tracd: {{{ tracd -p 8080 --basic-auth=environmentname,/fullpath/environmentname/.htpasswd,/fullpath/environmentname /fullpath/environmentname }}} Tracd provides support for both Basic and Digest authentication. The default is to use Digest; to use Basic authentication, replace --auth with --basic-auth in the examples below. (You must still specify a dialogic "realm", which can be an empty string by trailing the BASICAUTH with a comma.) ''Support for Basic authentication was added in version 0.9.'' The general format for using authentication is: {{{$ tracd -p port --auth=base_project_dir,password_file_path,realm project_path }}} where: * '''base_project_dir''' is the base directory of the project; note: this doesn't refer to the project name, and it is case-sensitive even for windows environments * '''password_file_path''' path of the password file * '''realm''' realm * '''project_path''' path of the project Example: {{{ $tracd -p 8080 \ --auth=project1,/path/to/users.htdigest,mycompany.com /path/to/project1 }}} Of course, the digest file can be be shared so that it is used for more than one project: {{{$ tracd -p 8080 \ --auth=project1,/path/to/users.htdigest,mycompany.com \ --auth=project2,/path/to/users.htdigest,mycompany.com \ /path/to/project1 /path/to/project2 }}} Another way to share the digest file is to specify "*" for the project name: {{{ $tracd -p 8080 \ --auth=*,/path/to/users.htdigest,mycompany.com \ /path/to/project1 /path/to/project2 }}} == How to set up an htdigest password file ==$ sudo htpasswd /path/to/env/.htpasswd username2 }}} Then to start tracd run something like this: {{{ $tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname }}} For example: {{{$ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv }}} ''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD). === Using a htdigest password file === If 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 /conf folder along with the [TracIni trac.ini] file. Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error. == Generating Passwords Without Apache == === Generating Passwords Without Apache === If you don't have Apache available, you can use this simple Python script to generate your passwords: #!python from optparse import OptionParser import md5 # The md5 module is deprecated in Python 2.5 try: from hashlib import md5 except ImportError: from md5 import md5 realm = 'trac' # build the options parser.add_option("-p", "--password",action="store", dest="password", type = "string", help="the password to use") parser.add_option("-r", "--realm",action="store", dest="realm", type = "string", help="the realm in which to create the digest") (options, args) = parser.parse_args() if (options.username is None) or (options.password is None): parser.error("You must supply both the username and password") if (options.realm is not None): realm = options.realm # Generate the string to enter into the htdigest file realm = 'trac' kd = lambda x: md5.md5(':'.join(x)).hexdigest() kd = lambda x: md5(':'.join(x)).hexdigest() print ':'.join((options.username, realm, kd([options.username, realm, options.password]))) }}} {{{ python trac-digest.py -u username -p password >> c:\digest.txt tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name }}} Note: If you would like to use --basic-auth you need to use htpasswd tool from apache server to generate .htpasswd file. The remaining part is similar but make sure to use empty realm (i.e. coma after path). When using on Windows make sure to use -m option for it (did not tested it on *nix, so not sure if that is the case there).  If you do not have Apache, [trac:source:/tags/trac-0.11b2/contrib/htpasswd.py htpasswd.py] may help.  (Note that it requires a crypt or fcrypt module; see the source comments for details.) $python trac-digest.py -u username -p password >> c:\digest.txt$ tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name }}} Note: If you would like to use --basic-auth you need to use htpasswd tool from apache server to generate .htpasswd file. The remaining part is similar but make sure to use empty realm (i.e. coma after path). Make sure to use -m option for it.  If you do not have Apache, [trac:source:/tags/trac-0.11/contrib/htpasswd.py htpasswd.py] may help.  (Note that it requires a crypt or fcrypt module; see the source comments for details.) It is possible to use md5sum utility to generate digest-password file using such method: {{{ echo -e "${user}:trac:${password}\c" | md5sum - >>to-file }}} and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'. You can see attachment:trac-digest-corrected.sh for detail.$ printf "${user}:trac:${password}" | md5sum - >>user.htdigest }}} and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'. == Reference == Here's the online help, as a reminder (tracd --help): {{{ Usage: tracd [options] [projenv] ... Options: --version show program's version number and exit -h, --help show this help message and exit -a DIGESTAUTH, --auth=DIGESTAUTH [projectdir],[htdigest_file],[realm] --basic-auth=BASICAUTH [projectdir],[htpasswd_file],[realm] -p PORT, --port=PORT the port number to bind to -b HOSTNAME, --hostname=HOSTNAME the host name or IP address to bind to --protocol=PROTOCOL http|scgi|ajp -q, --unquote unquote PATH_INFO (may be needed when using ajp) --http10 use HTTP/1.0 protocol version (default) --http11 use HTTP/1.1 protocol version instead of HTTP/1.0 -e PARENTDIR, --env-parent-dir=PARENTDIR parent directory of the project environments --base-path=BASE_PATH the initial portion of the request URL's "path" -r, --auto-reload restart automatically when sources are modified -s, --single-env only serve a single project without the project list }}} == Tips == === Serving static content === If tracd is the only webserver used for the project, If tracd is the only web server used for the project, it can also be used to distribute static content (tarballs, Doxygen documentation, etc.) Example: given a $TRAC_ENV/htdocs/software-0.1.tar.gz file, the corresponding relative URL would be //chrome/site/software-0.1.tar.gz, which in turn can be written using the relative link syntax in the Wiki: [//chrome/site/software-0.1.tar.gz] The development version of Trac supports a new htdocs: TracLinks syntax for the above. With this, the example link above can be written simply htdocs:software-0.1.tar.gz. === Using apache rewrite rules === In some situations when you choose to use tracd behind apache, 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. which in turn can be written as htdocs:software-0.1.tar.gz (TracLinks syntax) or [//chrome/site/software-0.1.tar.gz] (relative link syntax). ''Support for htdocs: TracLinks syntax was added in version 0.10'' === Using tracd behind a proxy In some situations when you choose to use tracd behind Apache or another web server. In 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. If 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. See also [trac:TracOnWindowsIisAjp], [trac:TracNginxRecipe]. === Serving a different base path than / === Tracd supports serving projects with different base urls then /. The parameter name to change this is {{{ tracd --base-path=/some/path Tracd supports serving projects with different base urls than /. The parameter name to change this is {{{ \$ tracd --base-path=/some/path }}} ---- See also: TracInstall, TracCgi, TracModPython, TracGuide See also: TracInstall, TracCgi, TracModPython, TracGuide, [trac:TracOnWindowsStandalone#RunningTracdasservice Running tracd.exe as a Windows service]
