    1414== Apache web-server configuration ==
    5858On some systems, you ''may'' need to edit the shebang line in the `trac.cgi` file to point to your real Python installation path. On a Windows system you may need to configure Windows to know how to execute a .cgi file (Explorer -> Tools -> Folder Options -> File Types -> CGI).
     60=== Using WSGI ===
     62You can run a [ WSGI handler] [ under CGI].  You can [wiki:TracModWSGI#Thetrac.wsgiscript write your own application function], or use the deployed trac.wsgi's application.
    6064== Mapping Static Resources ==
    62 Out of the box, Trac will pass static resources such as style sheets or images through itself. For a CGI setup this is '''highly undesirable''', because this way CGI script is invoked for documents that could be much more efficiently served directly by web server.
    64 Web servers such as [ Apache] allow you to create “Aliases” to resources, giving them a virtual URL that doesn't necessarily reflect the layout of the servers file system. We already used this capability by defining a `ScriptAlias` for the CGI script. We also can map requests for static resources directly to the directory on the file system, avoiding processing these requests by CGI script.
    66 There are two primary URL paths for static resources - `/chrome/common` and `/chrome/site`. Plugins can add their own resources usually accessible by `/chrome/plugin` path, so its important to override only known paths and not try to make universal `/chrome` alias for everything.
    68 Add the following snippet to Apache configuration '''before''' the `ScriptAlias` for the CGI script, changing paths to match your deployment:
    69 {{{
    70 Alias /trac/chrome/common /path/to/trac/htdocs
    71 <Directory "/path/to/www/trac/htdocs">
    72   Order allow,deny
    73   Allow from all
    74 </Directory>
    75 }}}
    77 Note that we mapped `/trac` part of the URL to the `trac.cgi` script, and the path `/chrome/common` is the path you have to append to that location to intercept requests to the static resources.
    79 For example, if Trac is mapped to `/cgi-bin/trac.cgi` on your server, the URL of the Alias should be `/cgi-bin/trac.cgi/chrome/common`.
    81 Similarly, if you have static resources in a project's htdocs directory (which is referenced by /chrome/site URL in themes), you can configure Apache to serve those resources (again, put this '''before''' the `ScriptAlias` for the CGI script, and adjust names and locations to match your installation):
    83 {{{
    84 Alias /trac/chrome/site /path/to/projectenv/htdocs
    85 <Directory "/path/to/projectenv/htdocs">
    86   Order allow,deny
    87   Allow from all
    88 </Directory>
    89 }}}
    91 Alternatively to hacking `/trac/chrome/site`, you can directly specify path to static resources using `htdocs_location` configuration option in [wiki:TracIni trac.ini]:
    92 {{{
    93 [trac]
    94 htdocs_location =
    95 }}}
    97 Trac will then use this URL when embedding static resources into HTML pages. Of course, you still need to make the Trac `htdocs` directory available through the web server at the specified URL, for example by copying (or linking) the directory into the document root of the web server:
    98 {{{
    99 $ ln -s /path/to/www/trac/htdocs /var/www/
    100 }}}
    102 Note that in order to get this `htdocs` directory, you need first to extract the relevant Trac resources using the `deploy` command of TracAdmin:
    103 [[TracAdminHelp(deploy)]]
     66See TracInstall#MappingStaticResources.
    10668== Adding Authentication ==
    108 The simplest way to enable authentication with Apache is to create a password file. Use the `htpasswd` program to create the password file:
    109 {{{
    110 $ htpasswd -c /somewhere/trac.htpasswd admin
    111 New password: <type password>
    112 Re-type new password: <type password again>
    113 Adding password for user admin
    114 }}}
    116 After the first user, you dont need the "-c" option anymore:
    117 {{{
    118 $ htpasswd /somewhere/trac.htpasswd john
    119 New password: <type password>
    120 Re-type new password: <type password again>
    121 Adding password for user john
    122 }}}
    124   ''See the man page for `htpasswd` for full documentation.''
    126 After you've created the users, you can set their permissions using TracPermissions.
    128 Now, you'll need to enable authentication against the password file in the Apache configuration:
    129 {{{
    130 <Location "/trac/login">
    131   AuthType Basic
    132   AuthName "Trac"
    133   AuthUserFile /somewhere/trac.htpasswd
    134   Require valid-user
    135 </Location>
    136 }}}
    138 If you're hosting multiple projects you can use the same password file for all of them:
    139 {{{
    140 <LocationMatch "/trac/[^/]+/login">
    141   AuthType Basic
    142   AuthName "Trac"
    143   AuthUserFile /somewhere/trac.htpasswd
    144   Require valid-user
    145 </LocationMatch>
    146 }}}
    148 For better security, it is recommended that you either enable SSL or at least use the “digest” authentication scheme instead of “Basic”. Please read the [ Apache HTTPD documentation] to find out more. For example, on a Debian 4.0r1 (etch) system the relevant section  in apache configuration can look like this:
    149 {{{
    150 <Location "/trac/login">
    151     LoadModule auth_digest_module /usr/lib/apache2/modules/
    152     AuthType Digest
    153     AuthName "trac"
    154     AuthDigestDomain /trac
    155     AuthUserFile /somewhere/trac.htpasswd
    156     Require valid-user
    157 </Location>
    158 }}}
    159 and you'll have to create your .htpasswd file with htdigest instead of htpasswd as follows:
    160 {{{
    161 # htdigest /somewhere/trac.htpasswd trac admin
    162 }}}
    163 where the "trac" parameter above is the same as !AuthName above  ("Realm" in apache-docs).
