Question

我刚刚安装了Graphite（版本1.2.0），但我无法再次启动Apache2。这是我得到的错误日志：

 * The apache2 configtest failed.
Output of config test was:
[Thu Jan 18 20:12:39.906483 2018] [so:warn] [pid 2356] AH01574: module wsgi_module is already loaded, skipping
AH00526: Syntax error on line 56 of /etc/apache2/sites-enabled/apache2-graphite.conf:
WSGI process group not yet configured.
Action 'configtest' failed.
The Apache error log may have more information.

这是我的apache2-graphite.conf文件：

我真的不知道如何修复此错误。我不知道应该在哪里配置进程组。我很感激任何提示。

我们在Ubuntu 14.04上使用Python 2.7和mod_wsgi 2.7。我们的Apache2版本是2.4.7。

提前感谢！

编辑：我注意到一些奇怪的事情，我不知道它是否相关。在Apache2 error.log中，我找到了这一行：

[Thu Jan 18 18:00:38.112219 2018] [mpm_prefork:notice] [pid 30731] AH00163: Apache/2.4.7 (Ubuntu) PHP/5.5.9-1ubuntu4.20 OpenSSL/1.0.1f mod_wsgi/3.4 Python/2.7.6 configured -- resuming normal operations

它显示mod_wsgi配置了3.4版本，但实际上，当我运行ls -l /usr/lib/apache2/modules | grep wsgi时，我发现该机器运行的是2.7版本。

lrwxrwxrwx 1 root root      15 Nov 19  2014 mod_wsgi.so -> mod_wsgi.so-2.7

Answer 1

1.2尚未发布，最好使用1.1.1

<ul class="sublist"> <strong> Utilisateurs </strong> <li><a target="_blank" href="{% url "admin:auth_user_add" %}">Nouvel utilisateur</a></li> <li><a target="_blank" href="{% url "admin:auth_user_changelist" %}">Liste utilisateurs</a></li> </ul> <ul class="sublist"> <strong> Groupes </strong> <li><a target="_blank" href="{% url "admin:auth_group_add" %}">Nouveau groupe</a></li> <li><a target="_blank" href="{% url "admin:auth_group_changelist" %}">Liste groupes</a></li> </ul>

应该是：

WSGIScriptAlias /graphite /opt/graphite/conf/graphite.wsgi/graphite

Answer 2

它会出现该错误，因为您为WSGIDaemonProcess指定的名称是错误的，并且与WSGIApplicationGroup定义的名称不匹配。你也错过了一个WSGIImportScript指令，就像你试图设置它一样。无论如何，最好不要使用WSGIDaemonProcess graphite-web processes=5 threads=5 display-name='%{GROUP}' inactivity-timeout=120 user=_graphite group=_graphite WSGIProcessGroup graphite-web WSGIImportScript /opt/graphite/conf/graphite.wsgi process-group=graphite-api application-group=%{GLOBAL} WSGIScriptAlias /graphite /opt/graphite/conf/graphite.wsgi/graphite。

所以你有：

WSGIDaemonProcess graphite-web processes=5 threads=5 display-name='%{GROUP}' inactivity-timeout=120 user=_graphite group=_graphite

WSGIScriptAlias /graphite /opt/graphite/conf/graphite.wsgi/graphite process-group=graphite-web application-group=%{GLOBAL}

您应该使用：

/graphite

/graphite只应添加到WSGI脚本文件路径的末尾，如果石墨中的路由规则总是希望它的路径在开始时包含{{1}}，但是你无法挂载它位于站点的根目录，但需要在子URL处使用它，因为其他东西在同一主机名上运行。

安装Graphite 1.2版后，Apache2不会重启
