这篇文章主要讲解了“Ubuntu怎么配置Munin”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“Ubuntu怎么配置Munin”吧！
1. 添加apt源
1 2 3 | 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
1 | sudo apt–key adv —keyserver keyserver.ubuntu.com —recv–keys KEY_ID |
2. 创建依赖关系和安装
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

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. # #rrdcached_socket /var/run/rrdcached.sock # Drop somejuser@fnord.comm and anotheruser@trustauth.cn an email everytime # something changes (OK -> WARNING, CRITICAL -> OK, etc) #contact.sometrustauth.cnmand mail -s “Munin notification” somejuser@fnord.comm #contact.anothertrustauth.cnmand mail -s “Munin notification” anotheruser@trustauth.cn contact.ttlsa_monitor.command /usr/local/bin/sendEmail –f support@ttlsa.com –s smtp.exmail.qq.com –xu support@ttlsa.com –xp ttlsa.com –o message–content–type=html –o message–charset=utf8 –t monitor@ttlsa.com \ –u “* ${if:cfields PROBLEM }${if:wfields PROBLEM }${if:fofields RECOVERY } – ${var:host}/${var:graph_title} is ${if:cfields CRITICAL}${if:wfields WARNING}${if:fofields OK} *” \ –m “Group: ${var:group}<p> Host: ${var:host}<p> \ Warngin: ${loop<,>:wfields – ${var:value} outside range [${var:wrange}] (${var:label})}<p> \ Critical: ${loop<,>:cfields – ${var:value} outside range [${var:crange}] (${var:label})}<p> \ OK: ${ loop<,>:fofields – ${var:value} = ${var:label} }” \ –l /tmp/mail.log contact.ttlsa_monitor.always_send warning critical # # For those with Nagios, the following might come in handy.

4. 配置munin-node.conf
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 | # # Example config-file for munin-node # log_level 4 log_file /var/log/munin/munin–node.log pid_file /var/run/munin/munin–node.pid background 1 setsid 1 user root group root # This is the timeout for the whole transaction. # Units are in sec. Default is 15 min # # global_timeout 900 # This is the timeout for each plugin. # Units are in sec. Default is 1 min # # timeout 60 # Regexps for files to ignore ignore_file [\#~]$ ignore_file DEADJOE$ ignore_file \.bak$ ignore_file %$ ignore_file \.dpkg–(tmp|new|old|dist)$ ignore_file \.rpm(save|new)$ ignore_file \.pod$ # Set this if the client doesn’t report the correct hostname when # telnetting to trustauth.cn, port 4949 # #host_name trustauth.cn.localdomain host_name web1 # A list of addresses that are allowed to connect. This must be a # regular expression, since Net::Server does not understand CIDR-style # network notation unless the perl module Net::CIDR is installed. You # may repeat the allow line as many times as you’d like allow ^127\.0\.0\.1$ allow ^::1$ allow ^X\.X\.X\.X$ #munin master ip address # If you have installed the Net::CIDR perl module, you can use one or more # cidr_allow and cidr_deny address/mask patterns. A connecting client must # match any cidr_allow, and not match any cidr_deny. Note that a netmask # *must* be provided, even if it’s /32 # # Example: # # cidr_allow 127.0.0.1/32 # cidr_allow 192.0.2.0/24 # cidr_deny 192.0.2.42/32 # Which address to bind to; host N.N.N.N # host 127.0.0.1 # And which port port 4949 |
5. 插件生效
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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | 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。
1 | spawn–fcgi –s /var/run/munin/fcgi–graph.sock –U www–data –u munin –g munin /usr/lib/munin/cgi/munin–cgi–graph |
