    5 == Pros ==
     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
    67
    78 * Fewer dependencies: You don't need to install apache or any other web-server.
    8  * Fast: Should be almost as fast as the [wiki:TracModPython mod_python] version (and much faster than the [wiki:TracCgi CGI]).
     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
    910 * 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).
    1011
    11 == Cons ==
    12 
    13  * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache HTTPD.
     12== Cons
     13
     14 * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache httpd.
    1415 * No native HTTPS support: [http://www.rickk.com/sslwrap/ sslwrap] can be used instead,
    15    or [http://trac.edgewall.org/wiki/STunnelTracd stunnel -- a tutorial on how to use stunnel with tracd] or Apache with mod_proxy.

     18== Usage examples
    1819
    1920A single project on port 8080. (http://localhost:8080/)
    20 {{{
     21{{{#!sh
    2122 $ tracd -p 8080 /path/to/project
    2223}}}
    23 Stricly speaking this will make your Trac accessible to everybody from your network rather than ''localhost only''. To truly limit it use ''--hostname'' option.
    24 {{{
     24Strictly speaking this will make your Trac accessible to everybody from your network rather than ''localhost only''. To truly limit it use the `--hostname` option.
     25{{{#!sh
    2526 $ tracd --hostname=localhost -p 8080 /path/to/project
    2627}}}
    2728With more than one project. (http://localhost:8080/project1/ and http://localhost:8080/project2/)
    28 {{{
     29{{{#!sh
    2930 $ tracd -p 8080 /path/to/project1 /path/to/project2
    3031}}}
     
    3435
    3536An 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{{{#!sh
     38 $ tracd -p 8080 -e /path/to
     39}}}
     40
     41There is support for the HTTPS protocol (//Since 1.3.4//). Specify the path to the PEM certificate file and keyfile using the `--certfile` and `--keyfile` options. You can specify just the `--certfile` option if you have a [https://docs.python.org/2/library/ssl.html#combined-key-and-certificate combined key and certificate].
     42
     43To exit the server on Windows, be sure to use `CTRL-BREAK` -- using `CTRL-C` will leave a Python process running in the background.
     44
     45== Installing as a Windows Service
     46
     47=== Option 1
     48To install as a Windows service, get the [https://www.google.com/search?q=srvany.exe SRVANY] utility and run:
     49{{{#!cmd
     50 C:\path\to\instsrv.exe tracd C:\path\to\srvany.exe
     51 reg add HKLM\SYSTEM\CurrentControlSet\Services\tracd\Parameters /v Application /d "\"C:\path\to\python.exe\" \"C:\path\to\python\scripts\tracd.exe\" <your tracd parameters>"
     52 net start tracd
     53}}}
     54
     55{{{#!div style="border: 1pt dotted; margin: 1em;"
     56**Attention:** Do not use `tracd.exe` directly.  Instead register `python.exe` directly with `tracd.exe` 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`.
     57}}}
     58
     59If you want tracd to start automatically when you boot Windows, do:
     60{{{#!cmd
     61 sc config tracd start= auto
     62}}}
     63
     64The spacing here is important.
     65
     66{{{#!div
     67Once 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]]
     68`HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tracd\Parameters`
     69
     70Three (string) parameters are provided:
     71||!AppDirectory ||C:\Python27\ ||
     72||Application ||python.exe ||
     73||!AppParameters ||scripts\tracd.exe -p 8080 ... ||
     74
     75Note 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.
     76(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.)
     77}}}
     78
     79For Windows 7 User, srvany.exe may not be an option, so you can use [https://www.google.com/search?q=winserv.exe WINSERV] utility and run:
     80{{{#!cmd
     81"C:\path\to\winserv.exe" install tracd -displayname "tracd" -start auto "C:\path\to\python.exe" c:\path\to\python\scripts\tracd.exe <your tracd parameters>"
     82net start tracd
     83}}}
     84
     85=== Option 2
     86
     87Use [https://trac-hacks.org/wiki/WindowsServiceScript WindowsServiceScript], available at [https://trac-hacks.org/ Trac Hacks]. Installs, removes, starts, stops, etc. your Trac service.
     88
     89=== Option 3
     90
     91also cygwin's cygrunsrv.exe can be used:
     92{{{#!sh
     93$ cygrunsrv --install tracd --path /cygdrive/c/Python27/Scripts/tracd.exe --args '--port 8000 --env-parent-dir E:\IssueTrackers\Trac\Projects'
     94$ net start tracd
     95}}}
     96
     97== Using Authentication
     98
     99Tracd 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)
     100
     101{{{#!div style="border: 1pt dotted; margin: 1em"
     102**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).
     103}}}
     104
     105Tracd 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.
     106
     107The general format for using authentication is:
     108{{{#!sh
     109 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
     110}}}
     111where:
     112 * '''base_project_dir''': the base directory of the project specified as follows:
     113   * when serving multiple projects: ''relative'' to the `project_path`
     114   * when serving only a single project (`-s`): the name of the project directory
     115 Don't use an absolute path here as this won't work. ''Note:'' This parameter is case-sensitive even for environments on Windows.
     116 * '''password_file_path''': path to the password file
     117 * '''realm''': the realm name (can be anything)
     118 * '''project_path''': path of the project
     119
     120 * **`--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.
     121
     122Examples:
     123
     124{{{#!sh
     125 $ tracd -p 8080 \
     126   --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1
     127}}}
     128
     129Of course, the password file can be be shared so that it is used for more than one project:
     130{{{#!sh
     131 $ tracd -p 8080 \
     132   --auth="project1,/path/to/passwordfile,mycompany.com" \
     133   --auth="project2,/path/to/passwordfile,mycompany.com" \
     134   /path/to/project1 /path/to/project2
     135}}}
     136
     137Another way to share the password file is to specify "*" for the project name:
     138{{{#!sh
     139 $ tracd -p 8080 \
     140   --auth="*,/path/to/users.htdigest,mycompany.com" \
     141   /path/to/project1 /path/to/project2
     142}}}
     143
     144=== Basic Authorization: Using a htpasswd password file
     145This section describes how to use `tracd` with Apache .htpasswd files.
     146
     147  Note: On Windows It is necessary to install the [https://pypi.python.org/pypi/passlib passlib]
     148  package in order to decode some htpasswd formats. Only `SHA-1` passwords (since Trac 1.0)
     149  work without this module.
     150
     151To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
     152{{{#!sh
     153 $ sudo htpasswd -c /path/to/env/.htpasswd username
     154}}}
     155then for additional users:
     156{{{#!sh
     157 $ sudo htpasswd /path/to/env/.htpasswd username2
     158}}}
     159
     160Then to start `tracd` run something like this:
     161{{{#!sh
     162 $ tracd -p 8080 --basic-auth="project,/fullpath/environmentname/.htpasswd,realmname" /path/to/project
     163}}}
     164
     165For example:
     166{{{#!sh
     167 $ tracd -p 8080 --basic-auth="project,/srv/tracenv/testenv/.htpasswd,My Test Env" /path/to/project
     168}}}
     169''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
     170
     171=== Digest authentication: Using a htdigest password file
     172
     173If you have Apache available, you can use the htdigest command to generate the password file. Type 'htdigest' to get some usage instructions, or read [https://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.
     174
     175Note that you can start tracd without the `--auth` argument, but if you click on the ''Login'' link you will get an error.
     176
     177=== Generating Passwords Without Apache
     178
     179Basic 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.
     180
     181Trac also provides `htpasswd` and `htdigest` scripts in `contrib`:
     182{{{#!sh
     183$ ./contrib/htpasswd.py -cb htpasswd user1 user1
     184$ ./contrib/htpasswd.py -b htpasswd user2 user2
     185}}}
     186
     187{{{#!sh
     188$ ./contrib/htdigest.py -cb htdigest trac user1 user1
     189$ ./contrib/htdigest.py -b htdigest trac user2 user2
     190}}}
     191
     192==== Using `md5sum`
     193It is possible to use `md5sum` utility to generate digest-password file:
     194{{{#!sh
     195user=
     196realm=
     197password=
     198path_to_file=
     199echo ${user}:${realm}:$(printf "${user}:${realm}:${password}" | md5sum - | sed -e 's/\s\+-//') > ${path_to_file}
     200}}}
     201
     202== Reference
     203
     204Here's the online help, as a reminder (`tracd -h` or `tracd --help`):
    36205{{{
    37  $ tracd -p 8080 -e /path/to
    38 }}}
    39 
    40 To exit the server on Windows, be sure to use {{{CTRL-BREAK}}} -- using {{{CTRL-C}}} will leave a Python process running in the background.
    41 
    42 
    43 == Using Authentication ==
    44 
    45 Using tracd with Apache .htpasswd files:
    46 
    47 To create a .htpasswd file using htpasswd:
    48 
    49 {{{
    50 sudo htpasswd -c /path/to/env/.htpasswd username
    51 }}}
    52 then for additional users:
    53 {{{
    54 sudo htpasswd /var/www/html/.htpasswd-users username2
    55 }}}
    56 then for starting the tracd:
    57 {{{
    58 tracd -p 8080 --basic-auth=environmentname,/fullpath/environmentname/.htpasswd,/fullpath/environmentname /fullpath/environmentname
    59 }}}
    60 
    61 
    62 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.)
    63 
    64   ''Support for Basic authentication was added in version 0.9.''
    65 
    66 The general format for using authentication is:
    67 
    68 {{{
    69  $ tracd -p port --auth=base_project_dir,password_file_path,realm project_path
    70 }}}
    71 
    72 where:
    73 
    74  * '''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
    75  * '''password_file_path''' path of the password file
    76  * '''realm''' realm
    77  * '''project_path''' path of the project
    78 
    79 Example:
    80 
    81 {{{
    82  $ tracd -p 8080 \
    83    --auth=project1,/path/to/users.htdigest,mycompany.com /path/to/project1
    84 }}}
    85 Of course, the digest file can be be shared so that it is used for more than one project:
    86 {{{
    87  $ tracd -p 8080 \
    88    --auth=project1,/path/to/users.htdigest,mycompany.com \
    89    --auth=project2,/path/to/users.htdigest,mycompany.com \
    90    /path/to/project1 /path/to/project2
    91 }}}
    92 
    93 Another way to share the digest file is to specify "*"
    94 for the project name:
    95 {{{
    96  $ tracd -p 8080 \
    97    --auth=*,/path/to/users.htdigest,mycompany.com \
    98    /path/to/project1 /path/to/project2
    99 }}}
    100 
    101 == How to set up an htdigest password file ==
    102 
    103 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 <projectname>/conf folder along with the [TracIni trac.ini] file.
    104 
    105 Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error.
    106 
    107 == Generating Passwords Without Apache ==
    108 
    109 If you don't have Apache available, you can use this simple Python script to generate your passwords:
    110 
    111 {{{
    112 #!python
    113 from optparse import OptionParser
    114 import md5
    115 
    116 # build the options
    117 usage = "usage: %prog [options]"
    118 parser = OptionParser(usage=usage)
    119 parser.add_option("-u", "--username",action="store", dest="username", type = "string",
    120                   help="the username for whom to generate a password")
    121 parser.add_option("-p", "--password",action="store", dest="password", type = "string",
    122                   help="the password to use")
    123 (options, args) = parser.parse_args()
    124 
    125 # check options
    126 if (options.username is None) or (options.password is None):
    127    parser.error("You must supply both the username and password")
    128    
    129 # Generate the string to enter into the htdigest file
    130 realm = 'trac'
    131 kd = lambda x: md5.md5(':'.join(x)).hexdigest()
    132 print ':'.join((options.username, realm, kd([options.username, realm, options.password])))
    133 }}}
    134 
    135 Note: If you use the above script you must use the --auth option to tracd, not --basic-auth, and you must set the realm in the --auth value to 'trac' (without the quotes). Example usage (assuming you saved the script as trac-digest.py):
    136 
    137 {{{
    138 python trac-digest.py -u username -p password >> c:\digest.txt
    139 tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name
    140 }}}
    141 
    142 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.)
    143 
    144 It is possible to use md5sum utility to generate digest-password file using such method:
    145 {{{
    146 echo -e "${user}:trac:${password}\c" | md5sum - >>to-file
    147 }}}
    148 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.
    149 
    150 == Tips ==
    151 
    152 === Serving static content ===
    153 
    154 If `tracd` is the only webserver used for the project,
    155 it can also be used to distribute static content

     251== Tips
     252
     253=== Serving static content
     254
     255If `tracd` is the only web server used for the project,
     256it can also be used to distribute static content
    156257(tarballs, Doxygen documentation, etc.)
    157258
     
    160261
    161262Example: given a `$TRAC_ENV/htdocs/software-0.1.tar.gz` file,
    162 the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
    163 which in turn can be written using the relative link syntax
    164 in the Wiki: `[/<project_name>/chrome/site/software-0.1.tar.gz]`
    165 
    166 The development version of Trac supports a new `htdocs:` TracLinks
    167 syntax for the above. With this, the example link above can be written simply
    168 `htdocs:software-0.1.tar.gz`.
    169 
    170 === Using apache rewrite rules ===
    171 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.
    172 
    173 === Serving a different base path than / ===
    174 Tracd supports serving projects with different base urls then /<project>. The parameter name to change this is
    175 {{{
    176 tracd --base-path=/some/path
     263the corresponding relative URL would be `/<project_name>/chrome/site/software-0.1.tar.gz`,
     264which 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).
     265
     266=== Using tracd behind a proxy
     267
     268In some situations when you choose to use tracd behind Apache or another web server.
     269
     270In 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.
     271
     272If 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.
     273
     274See also [trac:TracOnWindowsIisAjp], [trac:TracNginxRecipe].
     275
     276=== Authentication for tracd behind a proxy
     277It 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].
     278
     279Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap.
     280
     281First we bring tracd into Apache's location namespace.
     282
     283{{{#!apache
     284<Location /project/proxified>
     285        Require ldap-group cn=somegroup, ou=Groups,dc=domain.com
     286        Require ldap-user somespecificusertoo
     287        ProxyPass http://localhost:8101/project/proxified/
     288        # Turns out we don't really need complicated RewriteRules here at all
     289        RequestHeader set REMOTE_USER %{REMOTE_USER}s
     290</Location>
     291}}}
     292
     293Then 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:
     294{{{#!python
     295from trac.core import *
     296from trac.config import BoolOption
     297from trac.web.api import IAuthenticator
     298
     299class MyRemoteUserAuthenticator(Component):
     300
     301    implements(IAuthenticator)
     302
     303    obey_remote_user_header = BoolOption('trac', 'obey_remote_user_header', 'false',
     304               """Whether the 'Remote-User:' HTTP header is to be trusted for user logins
     305                (''since ??.??').""")
     306
     307    def authenticate(self, req):
     308        if self.obey_remote_user_header and req.get_header('Remote-User'):
     309            return req.get_header('Remote-User')
     310        return None
     311
     312}}}
     313
     314Add this new parameter to your TracIni:
     315{{{#!ini
     316[trac]
     317...
     318obey_remote_user_header = true
     319...
     320}}}
     321
     322Run tracd:
     323{{{#!sh
     324tracd -p 8101 -s proxified --base-path=/project/proxified
     325}}}
     326
     327Note 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.
     328
     329Global config (e.g. `/srv/trac/conf/trac.ini`):
     330{{{#!ini
     331[components]
     332remote-user-auth.* = enabled
     333[inherit]
     334plugins_dir = /srv/trac/plugins
     335[trac]
     336obey_remote_user_header = true
     337}}}
     338
     339Environment config (e.g. `/srv/trac/envs/myenv`):
     340{{{#!ini
     341[inherit]
     342file = /srv/trac/conf/trac.ini
     343}}}
     344
     345=== Serving a different base path than /
     346Tracd supports serving projects with different base urls than /<project>. The parameter name to change this is
     347{{{#!sh
     348 $ tracd --base-path=/some/path
    177349}}}
