munin 搭建及其配置

Munin 用户监控服务器负载，硬件使用情况，网络流量情况

服务器端安装

yum install munin munin-node  munin-nginx  varnish

服务器端启动服务

service munin-node start

service varnish start

spawn-fcgi -s /var/run/munin/fastcgi-graph.sock -U nginx   -u nginx -g munin /var/www/cgi-bin/munin-cgi-graph

#dbdir   /var/lib/munin 数据库文件

htmldir /data/app/munin/html  webroot 目录 其他服务器监控缓存生成

#logdir /data/log/munin 日志 

#rundir  /var/run/munin 

nginx 配置

server

{

    listen 80;

    server_name 10.9.9.1;

    root /data/app/munin/html;

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

        fastcgi_split_path_info ^(/munin-cgi/munin-cgi-graph)(.*);

        fastcgi_param PATH_INFO $fastcgi_path_info;

        fastcgi_pass unix:/var/run/munin/fastcgi-graph.sock;

    }

    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/munin/fastcgi-html.sock;

    }

}

服务器端增加模块

/etc/munin/munin.conf

[10.9.9.2]

    address 10.9.9.2

    use_node_name yes

防火墙修改

客户端安装：

yum install  munin-node   varnish

vim /etc/munin/munin-node.conf

allow ^10\.9\.9\.1$  #允许访问的IP

port 4949

防火墙修改 需要允许 ALLOW IP 访问 4949端口

图片时间选择问题

 vim   /etc/munin/static/dynazoom.html +109

return ((+form.stop_epoch.value) - (+form.start_epoch.value)) / (+form.size_x.value/2);
