4 | | Trac では [http://www.modpython.org/ mod_python] を利用可能です。 [http://www.modpython.org/ mod_python] は Trac のレスポンスタイムを飛躍的に向上し、特に [TracCgi CGI] と比べて、 [wiki:TracStandalone tracd]/mod_proxy では使用できない多くの Apache 機能を使えるようにします。 |
5 | | |
6 | | == シンプルなコンフィグレーション == |
7 | | |
8 | | もし mod_python をインストールしたならば、 Apache の設定ファイルに以下の一行を追加してモジュールをロードしなければなりません: |
| 4 | Trac 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. |
| 5 | |
| 6 | These instructions are for Apache 2; if you are still using Apache 1.3, you may have some luck with [wiki:TracModPython2.7 TracModPython2.7]. |
| 7 | |
| 8 | == Simple configuration == |
| 9 | |
| 10 | If you just installed mod_python, you may have to add a line to load the module in the Apache configuration: |
13 | | ''Note: モジュールがインストールされている正しいパスは HTTPD をどこにインストールしたかによって変わります。'' |
14 | | |
15 | | httpd.conf に以下の記述を追加してmod_python が正しくインストールされているかどうかを確かめることができます。セキュリティ上の理由で、この記述はテストが終了したら削除すべきです。 |
16 | | {{{ |
| 15 | ''Note: The exact path to the module depends on how the HTTPD installation is laid out.'' |
| 16 | On Debian using apt-get |
| 17 | {{{ |
| 18 | apt-get install libapache2-mod-python libapache2-mod-python-doc |
| 19 | }}} |
| 20 | (Still on Debian) after you have installed mod_python, you must enable the modules in apache2 (equivalent of the above Load Module directive): |
| 21 | {{{ |
| 22 | a2enmod mod_python |
| 23 | }}} |
| 24 | On Fedora use, using yum: |
| 25 | {{{ |
| 26 | yum install mod_python |
| 27 | }}} |
| 28 | 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. Note: mod_python.testhandler is only available in mod_python 3.2+. |
| 29 | {{{ |
| 30 | #!xml |
33 | | '''`TracUriRoot`''' オプションは不要な場合もあります。 `TracUriRoot` オプションを付けずに試し、 Trac が正しく URL を生成できないようであれば '''`TracUriRoot`''' を追加して下さい。 `Location` と '''`TracUriRoot`''' が同じパスになることに気づくでしょう。 |
34 | | |
35 | | === 認証設定 === |
36 | | |
37 | | 認証の設定は [wiki:TracCgi#認証を追加する CGI] と同じです: |
38 | | {{{ |
39 | | <Location "/projects/myproject/login"> |
| 50 | The option '''`TracUriRoot`''' may or may not be necessary in your setup. Try your configuration without it; if the URLs produced by Trac look wrong, if Trac does not seem to recognize URLs correctly, or you get an odd "No handler matched request to..." error, add the '''`TracUriRoot`''' option. You will notice that the `Location` and '''`TracUriRoot`''' have the same path. |
| 51 | |
| 52 | The options available are |
| 53 | {{{ |
| 54 | # For a single project |
| 55 | PythonOption TracEnv /var/trac/myproject |
| 56 | # For multiple projects |
| 57 | PythonOption TracEnvParentDir /var/trac/myprojects |

| 67 | PythonOption PYTHON_EGG_CACHE /var/trac/myprojects/egg-cache |
| 68 | }}} |
| 69 | |
| 70 | === Configuring Authentication === |
| 71 | |
| 72 | Creating password files and configuring authentication works similar to the process for [wiki:TracCgi#AddingAuthentication CGI]: |
| 73 | {{{ |
| 74 | #!xml |
| 75 | <Location /projects/myproject/login> |
47 | | === !PythonPath を設定する === |
48 | | |
49 | | もし Trac のインストールが、通常の Python ライブラリのパスの中に無い場合、 Apache が Trac の mod_python ハンドルを見つけられるように `PythonPath` ディレクティブで指定しなければなりません: |
50 | | {{{ |
| 83 | Configuration for mod_ldap authentication in Apache is a bit tricky (httpd 2.2.x and OpenLDAP: slapd 2.3.19) |
| 84 | |
| 85 | 1. You need to load the following modules in Apache httpd.conf |
| 86 | {{{ |
| 87 | LoadModule ldap_module modules/mod_ldap.so |
| 88 | LoadModule authnz_ldap_module modules/mod_authnz_ldap.so |
| 89 | }}} |
| 90 | |
| 91 | 2. Your httpd.conf also needs to look something like: |
| 92 | |
| 93 | {{{ |
| 94 | #!xml |
| 95 | <Location /trac/> |
| 96 | SetHandler mod_python |
| 97 | PythonInterpreter main_interpreter |
| 98 | PythonHandler trac.web.modpython_frontend |
| 99 | PythonOption TracEnv /home/trac/ |
| 100 | PythonOption TracUriRoot /trac/ |
| 101 | Order deny,allow |
| 102 | Deny from all |
| 103 | Allow from 192.168.11.0/24 |
| 104 | AuthType Basic |
| 105 | AuthName "Trac" |
| 106 | AuthBasicProvider "ldap" |
| 107 | AuthLDAPURL "ldap://127.0.0.1/dc=example,dc=co,dc=ke?uid?sub?(objectClass=inetOrgPerson)" |
| 108 | authzldapauthoritative Off |
| 109 | require valid-user |
| 110 | </Location> |
| 111 | }}} |
| 112 | |
| 113 | Or the LDAP interface to a Microsoft Active Directory: |
| 114 | |
| 115 | {{{ |
| 116 | #!xml |
| 117 | <Location /trac/> |
| 118 | SetHandler mod_python |
| 119 | PythonInterpreter main_interpreter |
| 120 | PythonHandler trac.web.modpython_frontend |
| 121 | PythonOption TracEnv /home/trac/ |
| 122 | PythonOption TracUriRoot /trac/ |
| 123 | Order deny,allow |
| 124 | Deny from all |
| 125 | Allow from 192.168.11.0/24 |
| 126 | AuthType Basic |
| 127 | AuthName "Trac" |
| 128 | AuthBasicProvider "ldap" |
| 129 | AuthLDAPURL "ldap://adserver.company.com:3268/DC=company,DC=com?sAMAccountName?sub?(objectClass=user)" |
| 130 | AuthLDAPBindDN ldap-auth-user@company.com |
| 131 | AuthLDAPBindPassword "the_password" |
| 132 | authzldapauthoritative Off |
| 133 | # require valid-user |
| 134 | require ldap-group CN=Trac Users,CN=Users,DC=company,DC=com |
| 135 | </Location> |
| 136 | }}} |
| 137 | |
| 138 | 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. |
| 139 | |
| 140 | Note 2: Active Directory requires an authenticating user/password to access records (AuthLDAPBindDN and AuthLDAPBindPassword). |
| 141 | |
| 142 | Note 3: The directive "require ldap-group ..." specifies an AD group whose members are allowed access. |
| 143 | |
| 144 | |
| 145 | |
| 146 | === Setting the !PythonPath === |
| 147 | |
| 148 | If the Trac installation isn't installed in your Python path, you'll have to tell Apache where to find the Trac mod_python handler using the `PythonPath` directive: |
| 149 | {{{ |
| 150 | #!xml |
127 | | === フォームを送信するときの問題 === |
128 | | |
129 | | もし、 Trac で何かしらのフォームを送信したときに、トラブルに見舞われたら(よくある問題として、送信後にスタートページにリダイレクトされてしまうという問題があります)、 {{{DocumentRoot}}} の中に mod_python をマッピングしたパスと同じフォルダやファイルが存在しないか確認してください。どういうわけか、 mod_python は静的リソースと同じところにマッピングされると混乱してしまいます。 |
130 | | |
131 | | === 仮想ホストの設定においての問題 === |
132 | | |
133 | | もし <Location /> ディレクティブが使用されているとき、 `DocumentRoot` を設定すると ''403 (Forbidden)'' エラーになるでしょう。 `DocumentRoot` ディレクティブを削除するか、アクセスが許されているディレクトリに設定されているかどうかを確認して下さい (対応する `<Directory>` ブロックにて) |
134 | | |
135 | | <Location /> で `SetHandler` を使用すると、すべてを mod_python でハンドルすることになりますが、いかなる CSS も image/icons もダウンロードできなくなります。この問題を回避するために、 <Location /trac> で `SetHandler None` を使用しています。しかし、この方法がエレガントな解決方法だとは思っていません。 |
136 | | |
137 | | === .htaccess ファイルを使用する === |
138 | | |
139 | | ディレクトリの設定をほんのちょっと修正するには `.htaccess` ファイルを使用すればいいかもしれませんが、これは動作しません。 Apache が Trac URL に "/" (スラッシュ) を追加すると、正しい動作を妨げてしまいます。 |
140 | | |
141 | | それでは、 mod_rewrite を使用すればいいように見えますが、これも動作しません。とにかく、百害あって一理なしです。指示に従ってください。:) |
142 | | |
143 | | === Win32 での特記 === |
144 | | Windows 上で mod_python 3.2 より前のバージョンで Trac を動かしている場合、 添付ファイルのアップロードが '''動かない''' でしょう。この問題は 3.1.4 以降で解決されました。 mod_python をアップグレードしてこの問題を解決してください。 |
145 | | |
146 | | === OS X での特記 === |
147 | | |
148 | | OS X で mod_python を使用するとき、 `apachectl restart` コマンドで Apache の再起動ができないでしょう。これは、 mod_python 3.2 でおそらく修正されるでしょう。しかし、 [http://www.dscpl.com.au/projects/vampire/patches.html ここ] にあるパッチを適用すれば、 3.2 以前のバージョンでもこの問題を回避できます。 |
149 | | |
150 | | === SELinux での特記 === |
151 | | |
152 | | もし、 Trac が ''Cannot get shared lock on db.lock'' というようなメッセージが出力されたら、 |
153 | | リポジトリに セキュリティコンテキストを設定する必要があるでしょう: |
| 238 | For multiple projects, try restarting the server as well. |
| 239 | |
| 240 | === Expat-related segmentation faults === #expat |
| 241 | |
| 242 | This problem will most certainly hit you on Unix when using Python 2.4. |
| 243 | In Python 2.4, some version of Expat (an XML parser library written in C) is used, |
| 244 | and if Apache is using another version, this results in segmentation faults. |
| 245 | As Trac 0.11 is using Genshi, which will indirectly use Expat, that problem |
| 246 | can now hit you even if everything was working fine before with Trac 0.10. |
| 247 | |
| 248 | See Graham Dumpleton's detailed [http://www.dscpl.com.au/wiki/ModPython/Articles/ExpatCausingApacheCrash explanation and workarounds] for the issue. |
| 249 | |
| 250 | === Form submission problems === |
| 251 | |
| 252 | If you're experiencing problems submitting some of the forms in Trac (a common problem is that you get redirected to the start page after submission), check whether your {{{DocumentRoot}}} contains a folder or file with the same path that you mapped the mod_python handler to. For some reason, mod_python gets confused when it is mapped to a location that also matches a static resource. |
| 253 | |
| 254 | === Problem with virtual host configuration === |
| 255 | |
| 256 | If the <Location /> directive is used, setting the `DocumentRoot` may result in a ''403 (Forbidden)'' error. Either remove the `DocumentRoot` directive, or make sure that accessing the directory it points is allowed (in a corresponding `<Directory>` block). |
| 257 | |
| 258 | Using <Location /> together with `SetHandler` resulted in having everything handled by mod_python, which leads to not being able download any CSS or images/icons. I used <Location /trac> `SetHandler None` </Location> to circumvent the problem, though I do not know if this is the most elegant solution. |
| 259 | |
| 260 | === Using .htaccess === |
| 261 | |
| 262 | Although it may seem trivial to rewrite the above configuration as a directory in your document root with a `.htaccess` file, this does not work. Apache will append a "/" to any Trac URLs, which interferes with its correct operation. |
| 263 | |
| 264 | It may be possible to work around this with mod_rewrite, but I failed to get this working. In all, it is more hassle than it is worth. Stick to the provided instructions. :) |
| 265 | |
| 266 | === Win32 Issues === |
| 267 | If 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. |
| 268 | |
| 269 | |
| 270 | === OS X issues === |
| 271 | |
| 272 | When 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]. |
| 273 | |
| 274 | === SELinux issues === |
| 275 | |
| 276 | If Trac reports something like: ''Cannot get shared lock on db.lock'' |
| 277 | The security context on the repository may need to be set: |
161 | | === FreeBSD での特記 === |
162 | | mod_python と sqlite パッケージのインストールバージョンに注意して下さい。 Ports には両パッケージともいろいろなバージョンがありますが、初期の pysqlite と mod_python は組み合わせることができません。前者は python のスレッド機能サポートが必要ですし、 後者 は python のスレッド機能なしのインストールが必要です。 |
163 | | |
164 | | === Subversion での特記 === |
165 | | |
166 | | Trac でコマンドライン、 TracStandalone で使用しているときは動くのに、 mod_python を使用しているときのみ、 `Unsupported version control system "svn"` というエラーが出力される場合、 [TracModPython#PythonPathを設定する PythonPath] ディレクティブに Python bindings へのパスを追加するのを忘れている可能性があります。 (Python の `site-packages` ディレクトリに Python binding へのパスをはるか、 `.pth` ファイルを作っておくのがベターです。) |
167 | | |
168 | | これに当てはまらない場合、使用している Subversion のライブラリが Apache が使用しているバージョンと適合性がないかもしれません。(たいてい `apr` ライブラリの不適合性が原因になります。)その場合、 Apache の svn モジュール (`mod_dav_svn`) も使用できないでしょう。 |
| 285 | === FreeBSD issues === |
| 286 | Pay 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. |
| 287 | |
| 288 | If you compiled and installed apache2, apache wouldn´t support threads (cause it doesn´t work very well on FreeBSD). You could force thread support when running ./configure for apache, using --enable-threads, but this isn´t recommendable. |
| 289 | The best option [[http://modpython.org/pipermail/mod_python/2006-September/021983.html seems to be]] adding to /usr/local/apache2/bin/ennvars the line |
| 290 | |
| 291 | {{{ |
| 292 | export LD_PRELOAD=/usr/lib/libc_r.so |
| 293 | }}} |
| 294 | |
| 295 | === Subversion issues === |
| 296 | |
| 297 | If you get the following Trac Error `Unsupported version control system "svn"` only under mod_python, though it works well on the command-line and even with TracStandalone, chances are that you forgot to add the path to the Python bindings with the [TracModPython#ConfiguringPythonPath PythonPath] directive. (The better way is to add a link to the bindings in the Python `site-packages` directory, or create a `.pth` file in that directory.) |
| 298 | |
| 299 | If this is not the case, it's possible that you're using Subversion libraries that are binary incompatible with the apache ones (an incompatibility of the `apr` libraries is usually the cause). In that case, you also won't be able to use the svn modules for Apache (`mod_dav_svn`). |
| 300 | |
| 301 | 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: |
| 302 | {{{ |
| 303 | PythonInterpreter main_interpreter |
| 304 | }}} |
| 305 | 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. |
| 306 | |
| 307 | === Page layout issues === |
| 308 | |
| 309 | 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: |
| 310 | {{{ |
| 311 | #!xml |
| 312 | Alias /myproject/css "/usr/share/trac/htdocs/css" |
| 313 | <Location /myproject/css> |
| 314 | SetHandler None |
| 315 | </Location> |
| 316 | }}} |
| 317 | |
| 318 | 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 />}}}. |
| 319 | |
| 320 | === HTTPS issues === |
| 321 | |
| 322 | 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: |
| 323 | {{{ |
| 324 | #!xml |
| 325 | <VirtualHost * > |
| 326 | DocumentRoot /var/www/myproject |
| 327 | ServerName trac.mycompany.com |
| 328 | SetEnv HTTPS 1 |
| 329 | .... |
| 330 | </VirtualHost> |
| 331 | }}} |
| 332 | |
| 333 | === Fedora 7 Issues === |
| 334 | Make sure you install the 'python-sqlite2' package as it seems to be required for TracModPython but not for tracd |
| 335 | |
| 336 | |
| 337 | === Segmentation fault with php5-mhash or other php5 modules === |
| 338 | 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]] |
| 339 | |
| 340 | 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]] |
