我使用Munin-cgi作为我的服务器的监控系统。 有一刻，我意识到我的error.log中有奇怪的，非常恼人的音符，而一切都保持良好运行，没有错误。
目前，我在Munin的apacheconfiguration文件中注释了所有内容，错误仍然出现。
这是我的configuration：
<VirtualHost *:80> <Directory /> Options -MultiViews </Directory> ScriptAlias /munin-cgi/munin-cgi-graph /usr/lib/munin/cgi/munin-cgi-graph </VirtualHost> 所以，如果我打电话给脚本：
http://<server>/munin-cgi/munin-cgi-graph/DOMAIN/HOST/PICTURE.png?&size_x=800&size_y=400
我在error.log中得到以下错误：
[Thu Oct 20 22:40:32.016850 2016] [authz_core:error] [pid 25196] [client 192.168.235.77:46192] AH01630: client denied by server configuration: /var/www/DOMAIN
而已。 即使打开了最大跟踪级别，我也没有看到任何可疑信息。 脚本正在工作，我看到它的输出，但每次调用脚本，Apache删除/munin-cgi/munin-cgi-graph/并尝试访问http://<server>//DOMAIN/HOST/PICTURE.png 。 即使我创build文件/var/www/DOMAIN/HOST/PICTURE.png/index.html cgi脚本仍然继续被调用，显然，在error.log消息消失。
也许在顶层apacheconfiguration文件的某个地方有一个错误，但是我仍然无法find它。
停止警告的唯一方法是写
<Location /> Require all granted </Location>
但是，这当然不安全
UPD：这是mod_rewrite开启的日志：

不要在你的虚拟主机中放置一个<Directory />块，在全局上下文中只应该有一个，你应该保持独立。 <Directory>指令的参数是一个不是URIpath的文件系统path。
你需要一个目录块来允许访问ScriptAlias的目标。 就像是：
<Directory "/usr/lib/munin/cgi/munin-cgi-graph"> require all granted </Directory>
如果没有这个，Apache不允许从该文件系统目录中提供任何东西。
