Munin 2.0 Ubuntu 12.04 nginx sendEmail

更新：2022-05-21 11:39:24编辑：Story归类：监控人气：162

Munin 监控非常轻巧，不过被监控节点多了就吃不消了，小规模的用这个蛮适合。

1. 添加apt源

sudo add-apt-repository ppa:tuxpoldo/munin
sudo apt-get update
sudo apt-get dist-upgrade

sudo add - apt - repository ppa : tuxpoldo / munin

sudo apt - get update

sudo apt - get dist - upgrade

可能要导入key，方法如下

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys KEY_ID

1	sudo apt - key adv -- keyserver keyserver . ubuntu . com -- recv - keys KEY_ID

2. 创建依赖关系和安装

sudo apt-get build-dep munin
sudo apt-get install munin munin-node

1 2	sudo apt - get build - dep munin sudo apt - get install munin munin - node

munin主节点需要安装munin和munin-node，被监控节点只需要安装munin-node。

3. 配置munin.conf

# Example configuration file for Munin, generated by 'make build'

# The next three variables specifies where the location of the RRD
# databases, the HTML output, logs and the lock/pid files.  They all
# must be writable by the user running munin-cron.  They are all
# defaulted to the values you see here.
#
#dbdir  /var/lib/munin
#htmldir /var/cache/munin/www
#logdir /var/log/munin
#rundir  /var/run/munin

# Where to look for the HTML templates
#
#tmpldir        /etc/munin/templates

# Where to look for the static www files
#
#staticdir /etc/munin/static

# temporary cgi files are here. note that it has to be writable by 
# the cgi user (usually nobody or httpd).
#
# cgitmpdir /var/lib/munin/cgi-tmp

# (Exactly one) directory to include all files from.
includedir /etc/munin/munin-conf.d

# You can choose the time reference for "DERIVE" like graphs, and show
# "per minute", "per hour" values instead of the default "per second"
#
#graph_period second

# Graphics files are generated either via cron or by a CGI process.
# See http://munin-monitoring.org/wiki/CgiHowto2 for more
# documentation.
# Since 2.0, munin-graph has been rewritten to use the cgi code. 
# It is single threaded *by design* now.
#
#graph_strategy cron

# munin-cgi-graph is invoked by the web server up to very many times at the
# same time.  This is not optimal since it results in high CPU and memory
# consumption to the degree that the system can thrash.  Again the default is
# 6.  Most likely the optimal number for max_cgi_graph_jobs is the same as
# max_graph_jobs.
#
#munin_cgi_graph_jobs 6

# If the automatic CGI url is wrong for your system override it here:
#
#cgiurl_graph /munin-cgi/munin-cgi-graph

# max_size_x and max_size_y are the max size of images in pixel.
# Default is 4000. Do not make it too large otherwise RRD might use all
# RAM to generate the images.
# 
#max_size_x 4000
#max_size_y 4000

# HTML files are normally generated by munin-html, no matter if the
# files are used or not. You can change this to on-demand generation
# by following the instructions in http://munin-monitoring.org/wiki/CgiHowto2
# 
# Notes: 
# - moving to CGI for HTML means you cannot have graph generated by cron.
# - cgi html has some bugs, mostly you still have to launch munin-html by hand
# 
#html_strategy cron

# munin-update runs in parallel.
#
# The default max number of processes is 16, and is probably ok for you.
#
# If set too high, it might hit some process/ram/filedesc limits.
# If set too low, munin-update might take more than 5 min.
#
# If you want munin-update to not be parallel set it to 0.
#
#max_processes 16

# RRD updates are per default, performed directly on the rrd files.
# To reduce IO and enable the use of the rrdcached, uncomment it and set it to
# the location of the socket that rrdcached uses.

5. 插件生效

sudo munin-node-configure --<a href="http://www.ttlsa.com/shell/" title="shell"target="_blank">shell</a> --families=contrib,auto | sh -x

1	sudo munin - node - configure -- shell -- families = contrib , auto \| sh - x

或者，自己创建软连接即可。

6. 配置nginx

server {
        listen 80;
        server_name monitor.ttlsa.com;
        access_log  /data/logs/access-monitor.log;
        error_log /data/logs/error-monitor.log;
        location ^~ /munin-cgi/munin-cgi-graph/ {
                fastcgi_split_path_info ^(/munin-cgi/munin-cgi-graph)(.*);
                fastcgi_param PATH_INFO $fastcgi_path_info;
                fastcgi_pass unix:/var/run/munin/fcgi-graph.sock;
                include fastcgi_params;
        }
        location /munin/static/ {
                alias /etc/munin/static/;
        }
        location /munin {
                alias /var/cache/munin/www/;
                auth_basic "mechat munin";
                auth_basic_user_file "/etc/munin/munin-htpasswd";    
        }
        location / {
                rewrite ^/$ munin/ redirect; break;
        }
}

server {

listen 80 ;

server_name monitor . ttlsa . com ;

access_log / data / logs / access - monitor . log ;

error_log / data / logs / error - monitor . log ;

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 / fcgi - graph . sock ;

include fastcgi_params ;

}

location / munin / static / {

alias / etc / munin / static / ;

}

location / munin {

alias / var / cache / munin / www / ;

auth _basic "mechat munin" ;

auth_basic_user _file "/etc/munin/munin-htpasswd" ;

}

location / {

rewrite ^ / $ munin / redirect ; break ;

}

需要安装spawn-fcgi，并启动下面的进程。

spawn-fcgi -s /var/run/munin/fcgi-graph.sock -U www-data -u munin -g munin /usr/lib/munin/cgi/munin-cgi-graph

1	spawn - fcgi - s / var / run / munin / fcgi - graph . sock - U www - data - u munin - g munin / usr / lib / munin / cgi / munin - cgi - graph

7.web界面

就可以通过http://monitor.ttlsa.com/munin/ 界面查看监控图形了。
