munin nginx：没有dynazoom成图

我无法让Munin动态变焦工作.我确信这个问题与Nginx配置有关.任何生成缩放图的尝试都会在Nginx日志中触发以下错误条目：

2015/02/22 13:26:01 [error] 4782#0: *2580 open() "/data/munin/usr/share/munin/cgi/munin-cgi-graph/bellaria/antergos1.bellaria/diskstats_latency/AntergosVG_AntergosRoot-pinpoint=1421756527,1424607727.png" Failed (2: No such file or directory),client: 10.10.10.25,server: munin,request: "GET /usr/share/munin/cgi/munin-cgi-graph/bellaria/antergos1.bellaria/diskstats_latency/AntergosVG_AntergosRoot-pinpoint=1421756527,1424607727.png?&lower_limit=&upper_limit=&size_x=800&size_y=400 HTTP/1.1",host: "munin.bellaria",referrer: "http://munin.bellaria/static/dynazoom.html?cgiurl_graph=/usr/share/munin/cgi/munin-cgi-graph&plugin_name=bellaria/antergos1.bellaria/diskstats_latency/AntergosVG_AntergosRoot&size_x=800&size_y=400&start_epoch=1421756527&stop_epoch=1424607727"

具体来说,我怀疑fastCGI参数有问题.愿一个好友好的灵魂看看我的Munin虚拟服务器(见下文)并向我解释有什么问题？它让我发疯 – 但我有预感,任何专家都会在不到一秒的时间内发现问题……

# Munin server
server {
       listen 80;
    server_name munin munin.bellaria;
    root /data/munin;
    allow all;
    access_log logs/munin.access.log;
    error_log logs/munin.error.log;
    location / {
        index index.html index.htm index.PHP;
        }
    location ~ \.(PHP|html|html|cgi)${
        fastcgi_pass   unix:/run/PHP-fpm/PHP-fpm.sock;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        fastcgi_param   AUTH_USER $remote_user;
        fastcgi_param   REMOTE_USER $remote_user;
        fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_index  index.PHP;
        include        fastcgi.conf;
        }
location ^~ /cgi-bin/munin-cgi-graph/ {
    access_log off;
    fastcgi_split_path_info ^(/cgi-bin/munin-cgi-graph)(.*);
    fastcgi_param PATH_INFO $fastcgi_path_info;
    fastcgi_pass unix:/var/run/munin/fcgi-graph.sock;
    include fastcgi_params;
    }
   }

最佳答案

我在寻找解决问题和好消息的同时找到了这个！我解决了我的问题.我希望这也可以帮助你让munin在你的设置上工作.

要求：
> spawnfcgi：

>从https://github.com/lighttpd/spawn-fcgi克隆或下载邮政编码
>准备：

autoreconf -v -i

>编译和安装：

./configure && make && sudo make install

>初始化脚本(我不做systemd所以弄清楚如何制作服务)：

在/etc/init.d/munin-fcgi下安装上面的权限755

>在您的虚拟主机中,例如/etc/Nginx/conf.d/example.com.conf,将其添加到server {}块中.您可以更改允许的ip块以适合您的设置.我在本地服务器上做了这个,并希望munin图只能在本地使用.

location /munin {
#    alias /var/cache/munin/www;
    index index.html;
#    include /etc/Nginx/PHP.conf;
#    access_log off;
    allow 127.0.0.1;
    allow 192.168.0.0/16;
    deny all;                                
}
 
location ^~ /munin-cgi/munin-cgi-graph/ {
#   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;
    include fastcgi_params;
}
location  ^~ /munin-cgi/munin-cgi-html/ {

    fastcgi_param PATH_INFO $fastcgi_path_info;
    fastcgi_pass unix:/var/run/munin/fastcgi-munin-html.sock;
    include fastcgi_params;
}

>启动/etc/init.d/munin-fcgi启动并重新加载Nginx然后你就可以了.

p.s我将munin的html文件夹链接到我的vhost文件夹：ln -s / var / cache / munin / www / /var/www/example.com/munin -v.
