munin + nginx：没有dynazoom成图

我发现这一点，同时寻找解决我的问题和好消息！ 我解决了我的问题。 我希望这会帮助你让munin在你的设置上工作。

要求：

1. 从https://github.com/lighttpd/spawn-fcgi克隆或下载zip
2. 准备：

     autoreconf -v -i 

3. 编译并安装：

     ./configure && make && sudo make install

将上面的权限755安装在/etc/init.d/munin-fcgi下

位置/ munin {
 ＃别名/ var / cache / munin / www;
     index index.html;
 ＃include /etc/nginx/php.conf;
 ＃access_log off;

    否认一切;                                
 }

 ＃if（$ uri〜/ munin-cgi / munin-cgi-graph /（[^ /] *））{set $ path $ 1;  }
     fastcgi_split_path_info ^（/ munin-cgi / munin-cgi-graph）（。*）;
     fastcgi_param PATH_INFO $ fastcgi_path_info;
     fastcgi_pass unix：/var/run/munin/fastcgi-munin-graph.sock;
    包括fastcgi_params;
 }
位置^〜/ munin-cgi / munin-cgi-html / {
 ＃if（$ uri〜/ munin-cgi / munin-cgi-html /（[^ /] *））{set $ path $ 1;  }
     fastcgi_split_path_info ^（/ munin-cgi / munin-cgi-html）（。*）;
     fastcgi_param PATH_INFO $ fastcgi_path_info;
     fastcgi_pass unix：/var/run/munin/fastcgi-munin-html.sock;
    包括fastcgi_params;
 }

ps我没有连接munin的html文件夹到我的虚拟主机的文件夹： ln -s /var/cache/munin/www/ /var/www/example.com/munin -v 。

这听起来像是一个static/dynazoom.html定义的问题。 在我们的安装，我们有

 form.cgiurl_graph.value = qs.get("cgiurl_graph", "/munin-cgi/munin-cgi-graph"); 

我怀疑你有

 form.cgiurl_graph.value = qs.get("cgiurl_graph", "/usr/share/munin/cgi/munin-cgi-graph"); 

虽然它应该是

 form.cgiurl_graph.value = qs.get("cgiurl_graph", "/cgi-bin/munin-cgi-graph"); 

我仍然相信，这大致是问题所在。 只要对缩放图的请求以/cgi-bin/munin-cgi-graph开头，nginxconfiguration看起来就是正确的。 我没有看到/data/munin/...是从哪里来的。

尝试在可以监视浏览器发送的请求（fiddler，chrome开发工具）的环境中运行并查看实际发送的内容。

你确定你正在编辑dynazoom的正确副本吗？ 尝试做一个微不足道的可见变化来validation这一点。

我有与munin 2.0.21的Ubuntu 12.04类似的问题。
检查dynazoom在哪里试图findmunin-cgi-graph。
Munin的wiki说你应该configuration你的nginx fcgi-graph

 location ^~ /cgi-bin/munin-cgi-graph/ 

在我的情况下，当我用Chrome开发人员工具（networking选项卡）检查页面时，发现dynazoom试图从/ munin-cgi / munin-cgi-graph /不从/ cgi-bin / munin-cgi-图/ /它得到404 erorr而不是graphics

所以我只是改变了这个位置在nginxconfiguration：

  location ^~ /munin-cgi/munin-cgi-graph/ { access_log off; fastcgi_split_path_info ^(/munin-cgi/munin-cgi-graph)(.*); fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_pass unix:/var/run/munin/fcgi-graph.sock; include fastcgi_params; } 

看起来像你有同样的问题，你的munin-cgi-graph位置是不正确的，所以浏览器请求去root /data/munin就像错误说。

我想添加到这个对话中的东西。 来自the_architecht的信息是非常宝贵的，但至less对我来说是一个缺失的东西。

在这里使用CentOS 6.8：

–

1）更改了CGI文件的path，这些path可以通过locatefind：

 /var/www/cgi-bin/munin-cgi-graph /var/www/cgi-bin/munin-cgi-html 

我必须在启动脚本中逐行进行比较，并打破守护进程的开始行，以查看哪些错误让我追踪文件path差异。

–

2）日志的权限被设置为“munin”用户，导致了一个沉默的错误的种类。 为了解决这个问题，我把www-data用户添加到了munin组和chmod 664的日志文件中：

 -rw-rw-r-- 1 munin munin 0 Apr 27 20:35 /var/log/munin/munin-cgi-graph.log -rw-rw-r-- 1 munin munin 0 Apr 27 20:35 /var/log/munin/munin-cgi-html.log 

为了文件的权限放弃涉及的Munin维基在spawn-fcgi进程开始和strace -s1024结尾添加了-n，这给出了错误

write（2，[Thu Apr 27 21:47:35 2017] munin-cgi-html：无法在/ usr / share /下打开/var/log/munin/munin-cgi-html.log（Permission denied） perl5 / vendor_perl / Log / Log4perl / Appender / File.pm line 103. \ n“，180 [Thu Apr 27 21:47:35 2017] munin-cgi-html：无法打开/ var / log / munin / munin -cgi-html.log（Permission denied）at /usr/share/perl5/vendor_perl/Log/Log4perl/Appender/File.pm line 103。

我的最后的Nginx和spawn-fcgi在我的修改之下：
