    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). 
    5959 
     60=== Using WSGI === 
     61 
     62You can run a [http://henry.precheur.org/python/how_to_serve_cgi WSGI handler] [http://pythonweb.org/projects/webmodules/doc/0.5.3/html_multipage/lib/example-webserver-web-wsgi-simple-cgi.html under CGI].  You can [wiki:TracModWSGI#Thetrac.wsgiscript write your own application function], or use the deployed trac.wsgi's application. 
     63 
    6064== Mapping Static Resources == 
    6165 
    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. 
    63  
    64 Web servers such as [http://httpd.apache.org/ 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. 
    65  
    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. 
    67  
    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/common 
    71 Alias /trac/chrome/site /path/to/trac/htdocs/site 
    72 <Directory "/path/to/www/trac/htdocs"> 
    73   Order allow,deny 
    74   Allow from all 
    75 </Directory> 
    76 }}} 
    77  
    78 If using mod_python, you might want to add this too (otherwise, the alias will be ignored): 
    79 {{{ 
    80 <Location "/trac/chrome/common/"> 
    81   SetHandler None 
    82 </Location> 
    83 }}} 
    84  
    85 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.  
    86  
    87 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`. 
    88  
    89 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): 
    90  
    91 {{{ 
    92 Alias /trac/chrome/site /path/to/projectenv/htdocs 
    93 <Directory "/path/to/projectenv/htdocs"> 
    94   Order allow,deny 
    95   Allow from all 
    96 </Directory> 
    97 }}} 
    98  
    99 Alternatively to hacking `/trac/chrome/site`, you can directly specify path to static resources using `htdocs_location` configuration option in [wiki:TracIni trac.ini]: 
    100 {{{ 
    101 [trac] 
    102 htdocs_location = http://yourhost.example.org/trac-htdocs 
    103 }}} 
    104  
    105 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: 
    106 {{{ 
    107 $ ln -s /path/to/www/trac/htdocs /var/www/yourhost.example.org/trac-htdocs 
    108 }}} 
    109  
    110 Note that in order to get this `htdocs` directory, you need first to extract the relevant Trac resources using the `deploy` command of TracAdmin: 
    111 [[TracAdminHelp(deploy)]] 
    112  
     66See TracInstall#MappingStaticResources. 
    11367 
    11468== Adding Authentication == 
    11569 
    116 The simplest way to enable authentication with Apache is to create a password file. Use the `htpasswd` program to create the password file: 
    117 {{{ 
    118 $ htpasswd -c /somewhere/trac.htpasswd admin 
    119 New password: <type password> 
    120 Re-type new password: <type password again> 
    121 Adding password for user admin 
    122 }}} 
    123  
    124 After the first user, you dont need the "-c" option anymore: 
    125 {{{ 
    126 $ htpasswd /somewhere/trac.htpasswd john 
    127 New password: <type password> 
    128 Re-type new password: <type password again> 
    129 Adding password for user john 
    130 }}} 
    131  
    132   ''See the man page for `htpasswd` for full documentation.'' 
    133  
    134 After you've created the users, you can set their permissions using TracPermissions. 
    135  
    136 Now, you'll need to enable authentication against the password file in the Apache configuration: 
    137 {{{ 
    138 <Location "/trac/login"> 
    139   AuthType Basic 
    140   AuthName "Trac" 
    141   AuthUserFile /somewhere/trac.htpasswd 
    142   Require valid-user 
    143 </Location> 
    144 }}} 
    145  
    146 If you're hosting multiple projects you can use the same password file for all of them: 
    147 {{{ 
    148 <LocationMatch "/trac/[^/]+/login"> 
    149   AuthType Basic 
    150   AuthName "Trac" 
    151   AuthUserFile /somewhere/trac.htpasswd 
    152   Require valid-user 
    153 </LocationMatch> 
    154 }}} 
    155  
    156 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 [http://httpd.apache.org/docs/2.0/ 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: 
    157 {{{ 
    158 <Location "/trac/login"> 
    159     LoadModule auth_digest_module /usr/lib/apache2/modules/mod_auth_digest.so 
    160     AuthType Digest 
    161     AuthName "trac" 
    162     AuthDigestDomain /trac 
    163     AuthUserFile /somewhere/trac.htpasswd 
    164     Require valid-user 
    165 </Location> 
    166 }}} 
    167 and you'll have to create your .htpasswd file with htdigest instead of htpasswd as follows: 
    168 {{{ 
    169 # htdigest /somewhere/trac.htpasswd trac admin 
    170 }}} 
    171 where the "trac" parameter above is the same as !AuthName above  ("Realm" in apache-docs).
