Munin动态图缩放(dynazoom)不起作用(CentOS6，nginx，php-fpm)

本文介绍了Munin动态图缩放(dynazoom)不起作用(CentOS6，nginx，php-fpm)的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

CentOS 6.3
munin 2.0.17-1
php54(php-fpm)
nginx 1.2.6-1

通过"epel"存储库设置munin，并进行修补后，我将其与多个节点一起使用.但是，图形缩放不适用于任何图形.我最终在网上找到了一条建议，将* _strategy模式从HTML切换为cgi-这样做是为了使所有图表都不会更新(因为cgi无法正常工作)，并且缩放仍然中断.

Setup munin via the 'epel' repo and after tinkering, I got it working with multiple nodes. However the graph zoom did not work on any of the graphs. I ended up switching the *_strategy mode from HTML to cgi per a suggestion I found online - which made it so that none of the graphs are updating (since cgi isn't working) and the zoom is still broken.

我可以在线找到的所有指南(包括官方指南: http://munin-monitoring. org/wiki/CgiHowto2 )是指使用spawnfcgi(我曾经在较旧的CentOS5服务器上使用过)并为此生成了特定的实例.但是，我在此服务器上使用的是php-fpm而不是spawnfcgi，因此无法使其适应工作.

All of the guides that I can find online (including the official: http://munin-monitoring.org/wiki/CgiHowto2) refer to using spawnfcgi (which I used to use on an older CentOS5 server) and spawning specific instances for this. However, I'm utilizing php-fpm rather than spawnfcgi on this server am having trouble adapting this to work.

通过不起作用，我的意思是简单地说，该图形将不会加载到缩放"屏幕上，而是显示断开的图像链接. nginx错误日志显示:

By not working, I mean simply that the graph will not load on the 'zoom' screen but rather shows a broken image link. nginx error log shows:

2013/09/05 16:31:59 [error] 29384#0: *2 open() "/usr/share/nginx/vhosts/munin.mydomain.com/public_html/munin-cgi/munin-cgi-graph/mydomain.com/host.mydomain.com/postfix_mailvolume-pinpoint=1378299671,1378407671.png" failed (2: No such file or directory), client: 10.30.2.1, server: munin.mydomain.com, request: "GET /munin-cgi/munin-cgi-graph/mydomain.com/host.mydomain.com/postfix_mailvolume-pinpoint=1378299671,1378407671.png?&lower_limit=&upper_limit=&size_x=800&size_y=400 HTTP/1.1", host: "munin.mydomain.com", referrer: "http://munin.mydomain.com/static/dynazoom.html?cgiurl_graph=/munin-cgi/munin-cgi-graph&plugin_name=mydomain.com/host.mydomain.com/postfix_mailvolume&size_x=800&size_y=400&start_epoch=1378299671&stop_epoch=1378407671"

这是munin.conf:

Here is the munin.conf:

[16:42:21]$ cat /etc/munin/munin.conf | sed -e '/^#/d' -e '/^$/d'
htmldir /usr/share/nginx/vhosts/munin.mydomain.com/public_html/
includedir /etc/munin/conf.d
graph_strategy cgi
cgiurl_graph /munin-cgi/munin-cgi-graph
html_strategy cgi
[host.mydomain.com]
    address 127.0.0.1
    use_node_name yes
[otherhost.mydomain.com]
    address 1.2.3.4
    use_node_name yes

这是nginx的虚拟主机:

Here is the vhost for nginx:

[16:44:16]$ cat /etc/nginx/conf.d/vhosts/munin.thegnomedev.com.conf | sed -e '/^$/d' -e '/^#/d'
server {
    listen      80;
    server_name munin.mydomain.com;
    access_log /var/log/nginx/munin.mydomain.com combined;
    error_log /var/log/nginx/error.log warn;
    rewrite_log on;
    root    /usr/share/nginx/vhosts/munin.mydomain.com/public_html/;
    index   index.php index.html index.htm;
    location  /  {
        auth_basic            "Restricted";
        auth_basic_user_file  /usr/share/nginx/vhosts/munin.mydomain.com/.htpasswd;
    }
    location ^~ /cgi-bin/munin-cgi-graph/ {
        fastcgi_split_path_info ^(/cgi-bin/munin-cgi-graph)(.*);
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        include fastcgi_params;
    }
    location /munin/static/ {
        alias /etc/munin/static/;
    }
    location /munin/ {
        fastcgi_split_path_info ^(/munin)(.*);
        fastcgi_param PATH_INFO $fastcgi_path_info;
                fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        include fastcgi_params;
    }
    # Deny hidden file types
    location ~ /(\.ht|\.git|\.svn) {
    deny  all;
    }
}

在这一点上，我感到非常沮丧，以至于我觉得自己被锁死了.我承认，很可能是我对nginx语法及其与php-fpm的交互方式缺乏全面的了解-尤其是如果我可以对语法进行简单的更改以使其正常工作的话.

At this point, I'm frustrated enough that I think I'm hitting brain lock. I'll admit, it's likely that my lack of full understanding of nginx's syntax as well as how it interacts with php-fpm is probably to blame - especially if there is a simply syntax change that I can make to have this working.

在我现有的堆栈中解决此问题的任何帮助将不胜感激.在一天的大部分时间里一直在谷歌搜索和尝试各种事情.

Any help with resolving this with my existing stack would be most appreciated. Have been googling and trying various things for the better part of the day.

谢谢
