今天有点时间搞了一下munin cgi了,下面我们来看小编整理的一篇关于linux中使用munin cgi 动态生成图形文件的例子,希望对各位有帮助.

今天又弄了一下munin,发现有些图片出不来.

http://phpfensi.com/static/dynazoom.html?cgiurl_graph=/munin-cgi/munin-cgi-graph&plugin_name=xxxxxx 加载图片的地方报404错误.

1，安装munin

请参考:linux munin 服务器监控安装配置

2，安装munin-nginx

# yum install munin-nginx spawn-fcgi

安装完了以后,在4个地方,会产生重要文件.

[root@node1www]#ll/etc/nginx/conf.d/|grepmunin
-rw-r--r--1rootroot142712月3014:11munin.conf//nginx的配置文件
[root@node1www]#ll/var/www/cgi-bin/
总用量24
-rwxr-xr-x1rootmunin1453011月2703:37munin-cgi-graph//perlcgi程序
-rwxr-xr-x1rootmunin424511月2703:37munin-cgi-html
[root@node1www]#ll/etc/init.d/|grepmunin-fcgi
-rwxr-xr-x1rootroot112312月3019:22munin-fcgi-graph//调用munin-cgi-graph的系统脚本
-rwxr-xr-x1rootroot103712月2915:59munin-fcgi-html
[root@node1www]#whereisspawn-fcgi//perl程序的承载器

spawn-fcgi:/usr/bin/spawn-fcgi /usr/share/man/man1/spawn-fcgi.1.gz

在这里注意,/etc/init.d/munin-fcgi-graph,这个文件启动munin-cgi-graph,老是有问题,所以从官方网站找到了启动脚本.

3，修改munin.conf的主配置文件

[root@node1munin]#catmunin.conf|awk'{if($0!~/^$/&&$0!~/#/){print$0}}'
dbdir/var/lib/munin
htmldir/var/www/html/munin
logdir/var/log/munin
rundir/var/run/munin
tmpldir/etc/munin/templates
includedir/etc/munin/conf.d
graph_strategycgi//在此处将cron改为cgi
cgiurl_graph/munin-cgi/munin-cgi-graph
html_strategycron
[munin]
address127.0.0.1
use_node_nameyes

4,修改nginx的munin虚拟机

[root@node1www]#cat/etc/nginx/conf.d/munin.conf|awk'{if($0!~/^$/&&$0!~/#/){print$0}}'
server{
listen80;
server_namemunin.51yip.com;//自定义
root/var/www/html/munin;//muninhtml的根目录
indexindex.htmlindex.htm;
location^~/munin-cgi/munin-cgi-graph/{
fastcgi_split_path_info^(/munin-cgi/munin-cgi-graph)(.*);
fastcgi_paramPATH_INFO$fastcgi_path_info;
fastcgi_passunix:/var/run/munin/spawn-fcgi-munin-graph.sock;
includefastcgi_params;
}
}

5,启动脚本

[root@node1www]#cat/etc/init.d/spawn-fcgi-munin-graph|awk'{if($0!~/^$/&&$0!~/#/){print$0}}'
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
