  • TracModPython

    v2 v3  
    44Trac supports [http://www.modpython.org/ mod_python], which speeds up Trac's response times considerably, especially compared to [TracCgi CGI], and permits use of many Apache features not possible with [wiki:TracStandalone tracd]/mod_proxy. 
    55 
    6 These instructions are for Apache 2; if you are still using Apache 1.3, you may have some luck with [trac:wiki:TracModPython2.7 TracModPython2.7].

     7** A Word of Warning ** 
    98 
    109As of 16^th^ June 2010, the mod_python project is officially dead.  If you are considering using mod_python for a new installation, '''please don't'''!  There are known issues which will not be fixed and there are now better alternatives.  Check out the main TracInstall pages for your target version for more information.

     13These instructions are for Apache 2; if you are still using Apache 1.3, you may have some luck with [trac:wiki:TracModPython2.7 TracModPython2.7], but you'll be totally on your own.

     17== Simple configuration: single project == #Simpleconfiguration 
    1318 
    1419If you just installed mod_python, you may have to add a line to load the module in the Apache configuration: 
    … …  
    6368    # For a single project 
    6469    PythonOption TracEnv /var/trac/myproject 
     70 
    6571    # For multiple projects 
    6672    PythonOption TracEnvParentDir /var/trac/myprojects 
     73 
    6774    # For the index of multiple projects 
    6875    PythonOption TracEnvIndexTemplate /srv/www/htdocs/trac/project_list_template.html 
     76 
    6977    # A space delimitted list, with a "," between key and value pairs. 
    7078    PythonOption TracTemplateVars key1,val1 key2,val2 
     79 
    7180    # Useful to get the date in the wanted order 
    7281    PythonOption TracLocale en_GB.UTF8 
     82 
    7383    # See description above         
    7484    PythonOption TracUriRoot /projects/myproject 
    … …  
    8393 
    8494or you can uncompress the Genshi egg to resolve problems extracting from it.

    8596=== Configuring Authentication === 
    8697 
    87 Creating password files and configuring authentication works similar to the process for [wiki:TracCgi#AddingAuthentication CGI]: 
    88 {{{ 
    89 #!xml 
    90 <Location /projects/myproject/login> 
    91   AuthType Basic 
    92   AuthName "myproject" 
    93   AuthUserFile /var/trac/myproject/.htpasswd 
    94   Require valid-user 
    95 </Location> 
    96 }}} 
    97  
    98 Configuration for mod_ldap authentication in Apache is a bit tricky (httpd 2.2.x and OpenLDAP: slapd 2.3.19) 
    99  
    100 1. You need to load the following modules in Apache httpd.conf 
    101 {{{ 
    102 LoadModule ldap_module modules/mod_ldap.so 
    103 LoadModule authnz_ldap_module modules/mod_authnz_ldap.so 
    104 }}} 
    105  
    106 2. Your httpd.conf also needs to look something like: 
    107  
    108 {{{ 
    109 #!xml 
    110 <Location /trac/> 
    111   SetHandler mod_python 
    112   PythonInterpreter main_interpreter 
    113   PythonHandler trac.web.modpython_frontend 
    114   PythonOption TracEnv /home/trac/ 
    115   PythonOption TracUriRoot /trac/ 
    116   Order deny,allow 
    117   Deny from all 
    118   Allow from 192.168.11.0/24 
    119   AuthType Basic 
    120   AuthName "Trac" 
    121   AuthBasicProvider "ldap" 
    122   AuthLDAPURL "ldap://127.0.0.1/dc=example,dc=co,dc=ke?uid?sub?(objectClass=inetOrgPerson)" 
    123   authzldapauthoritative Off 
    124   require valid-user 
    125 </Location> 
    126 }}} 
    127  
    128 Or the LDAP interface to a Microsoft Active Directory: 
    129  
    130 {{{ 
    131 #!xml 
    132 <Location /trac/> 
    133   SetHandler mod_python 
    134   PythonInterpreter main_interpreter 
    135   PythonHandler trac.web.modpython_frontend 
    136   PythonOption TracEnv /home/trac/ 
    137   PythonOption TracUriRoot /trac/ 
    138   Order deny,allow 
    139   Deny from all 
    140   Allow from 192.168.11.0/24 
    141   AuthType Basic 
    142   AuthName "Trac" 
    143   AuthBasicProvider "ldap" 
    144   AuthLDAPURL "ldap://adserver.company.com:3268/DC=company,DC=com?sAMAccountName?sub?(objectClass=user)" 
    145   AuthLDAPBindDN       ldap-auth-user@company.com 
    146   AuthLDAPBindPassword "the_password" 
    147   authzldapauthoritative Off 
    148   # require valid-user 
    149   require ldap-group CN=Trac Users,CN=Users,DC=company,DC=com 
    150 </Location> 
    151 }}} 
    152  
    153 Note 1: This is the case where the LDAP search will get around the multiple OUs, conecting to Global Catalog Server portion of AD (Notice the port is 3268, not the normal LDAP 389). The GCS is basically a "flattened" tree which allows searching for a user without knowing to which OU they belong. 
    154  
    155 Note 2: Active Directory requires an authenticating user/password to access records (AuthLDAPBindDN and AuthLDAPBindPassword). 
    156  
    157 Note 3: The directive "require ldap-group ..."  specifies an AD group whose members are allowed access. 
    158  
     98See corresponding section in the [wiki:TracModWSGI#ConfiguringAuthentication] page.

    269212For multiple projects, try restarting the server as well. 
    270213 
     214===Login Not Working=== 
     215If you've used <Location /> directive, it will override any other directives, as well as <Location /Login>. 
     216The workaround is to use negation expression as follows (for multi project setups): 
     217{{{

    305280A success story: For me it worked out-of-box, with following trivial config: 
    306 {{{ 
     281{{{#!xml 
    307282SetHandler mod_python 
    308283PythonInterpreter main_interpreter

     307==== Win32 Issues ==== 
    333308If you run trac with mod_python < 3.2 on Windows, uploading attachments will '''not''' work. This problem is resolved in mod_python 3.1.4 or later, so please upgrade mod_python to fix this.

    336 === OS X issues === 
     311==== OS X issues ==== 
    337312 
    338313When using mod_python on OS X you will not be able to restart Apache using `apachectl restart`. This is apparently fixed in mod_python 3.2, but there's also a patch available for earlier versions [http://www.dscpl.com.au/projects/vampire/patches.html here].

    352327Pay attention to the version of the installed mod_python and sqlite packages. Ports have both the new and old ones, but earlier versions of pysqlite and mod_python won't integrate as the former requires threaded support in python, and the latter requires a threadless install.
