15 | | You can test your mod_python installation by adding the following to your httpd.conf. You should remove this when you are done testing for security reasons. |

| 21 | (Still on Debian) after you have installed mod_python, you must enable the modules in apache2 (equivalent of the above Load Module directive): |
| 22 | {{{ |

| 24 | }}} |
| 25 | On Fedora use, using yum: |

| 69 | === Python Egg Cache === |
| 70 | |
| 71 | Compressed python eggs like Genshi are normally extracted into a directory named `.python-eggs` in the users home directory. Since apache's home usually is not writable an alternate egg cache directory can be specified like this: |
| 72 | {{{ |
| 73 | PythonOption PYTHON_EGG_CACHE /var/trac/myprojects/egg-cache |
| 74 | }}} |
| 89 | Configuration for mod_ldap authentication in Apache is a bit tricky (httpd 2.2.x and OpenLDAP: slapd 2.3.19) |
| 90 | |
| 91 | 1. You need to load the following modules in Apache httpd.conf |
| 92 | {{{ |
| 93 | LoadModule ldap_module modules/mod_ldap.so |
| 94 | LoadModule authnz_ldap_module modules/mod_authnz_ldap.so |
| 95 | }}} |
| 96 | |
| 97 | 2. Your httpd.conf also needs to look something like: |
| 98 | |
| 99 | {{{ |
| 100 | #!xml |
| 101 | <Location /trac/> |
| 102 | SetHandler mod_python |
| 103 | PythonInterpreter main_interpreter |
| 104 | PythonHandler trac.web.modpython_frontend |
| 105 | PythonOption TracEnv /home/trac/ |
| 106 | PythonOption TracUriRoot /trac/ |
| 107 | Order deny,allow |
| 108 | Deny from all |
| 109 | Allow from 192.168.11.0/24 |
| 110 | AuthType Basic |
| 111 | AuthName "Trac" |
| 112 | AuthBasicProvider "ldap" |
| 113 | AuthLDAPURL "ldap://127.0.0.1/dc=example,dc=co,dc=ke?uid?sub?(objectClass=inetOrgPerson)" |
| 114 | authzldapauthoritative Off |
| 115 | require valid-user |
| 116 | </Location> |
| 117 | }}} |
| 118 | |
| 119 | Or the LDAP interface to a Microsoft Active Directory: |
| 120 | |
| 121 | {{{ |
| 122 | #!xml |
| 123 | <Location /trac/> |
| 124 | SetHandler mod_python |
| 125 | PythonInterpreter main_interpreter |
| 126 | PythonHandler trac.web.modpython_frontend |
| 127 | PythonOption TracEnv /home/trac/ |
| 128 | PythonOption TracUriRoot /trac/ |
| 129 | Order deny,allow |
| 130 | Deny from all |
| 131 | Allow from 192.168.11.0/24 |
| 132 | AuthType Basic |
| 133 | AuthName "Trac" |
| 134 | AuthBasicProvider "ldap" |
| 135 | AuthLDAPURL "ldap://adserver.company.com:3268/DC=company,DC=com?sAMAccountName?sub?(objectClass=user)" |
| 136 | AuthLDAPBindDN ldap-auth-user@company.com |
| 137 | AuthLDAPBindPassword "the_password" |
| 138 | authzldapauthoritative Off |
| 139 | # require valid-user |
| 140 | require ldap-group CN=Trac Users,CN=Users,DC=company,DC=com |
| 141 | </Location> |
| 142 | }}} |
| 143 | |
| 144 | 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. |
| 145 | |
| 146 | Note 2: Active Directory requires an authenticating user/password to access records (AuthLDAPBindDN and AuthLDAPBindPassword). |
| 147 | |
| 148 | Note 3: The directive "require ldap-group ..." specifies an AD group whose members are allowed access. |
| 149 | |
| 150 | |
| 151 | |
| 246 | For multiple projects, try restarting the server as well. |
| 247 | |
| 248 | === Expat-related segmentation faults === #expat |
| 249 | |
| 250 | This problem will most certainly hit you on Unix when using Python 2.4. |
| 251 | In Python 2.4, some version of Expat (an XML parser library written in C) is used, |
| 252 | and if Apache is using another version, this results in segmentation faults. |
| 253 | As Trac 0.11 is using Genshi, which will indirectly use Expat, that problem |
| 254 | can now hit you even if everything was working fine before with Trac 0.10. |
| 255 | |
| 256 | See Graham Dumpleton's detailed [http://www.dscpl.com.au/wiki/ModPython/Articles/ExpatCausingApacheCrash explanation and workarounds] for the issue. |
| 257 | |
| 325 | You also need a recent version of `mod_python` in order to avoid a runtime error ({{{argument number 2: a 'apr_pool_t *' is expected}}}) due to the default usage of multiple sub-interpreters. 3.2.8 ''should'' work, though it's probably better to use the workaround described in #3371, in order to force the use of the main interpreter: |
| 326 | {{{ |
| 327 | PythonInterpreter main_interpreter |
| 328 | }}} |
| 329 | This is anyway the recommended workaround for other well-known issues seen when using the Python bindings for Subversion within mod_python (#2611, #3455). See in particular Graham Dumpleton's comment in [comment:ticket:3455:9 #3455] explaining the issue. |
| 330 | |
| 331 | === Page layout issues === |
| 332 | |
| 333 | If the formatting of the Trac pages look weird chances are that the style sheets governing the page layout are not handled properly by the web server. Try adding the following lines to your apache configuration: |
| 334 | {{{ |
| 335 | #!xml |
| 336 | Alias /myproject/css "/usr/share/trac/htdocs/css" |
| 337 | <Location /myproject/css> |
| 338 | SetHandler None |
| 339 | </Location> |
| 340 | }}} |
| 341 | |
| 342 | Note: For the above configuration to have any effect it must be put after the configuration of your project root location, i.e. {{{<Location /myproject />}}}. |
| 343 | |
| 344 | === HTTPS issues === |
| 345 | |
| 346 | If you want to run Trac fully under https you might find that it tries to redirect to plain http. In this case just add the following line to your apache configuration: |
| 347 | {{{ |
| 348 | #!xml |
| 349 | <VirtualHost * > |
| 350 | DocumentRoot /var/www/myproject |
| 351 | ServerName trac.mycompany.com |
| 352 | SetEnv HTTPS 1 |
| 353 | .... |
| 354 | </VirtualHost> |
| 355 | }}} |
| 356 | |
| 357 | === Fedora 7 Issues === |
| 358 | Make sure you install the 'python-sqlite2' package as it seems to be required for TracModPython but not for tracd |
| 359 | |
| 360 | |
| 361 | === Segmentation fault with php5-mhash or other php5 modules === |
| 362 | You may encounter segfaults (reported on debian etch) if php5-mhash module is installed. Try to remove it to see if this solves the problem. See debian bug report [[http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=411487]] |
| 363 | |
| 364 | Some people also have troubles when using php5 compiled with its own 3rd party libraries instead of system libraries. Check here [[http://www.djangoproject.com/documentation/modpython/#if-you-get-a-segmentation-fault]] |
