1. 添加 apt 源

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

# 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.

#

#rrdcached_socket /var/run/rrdcached.sock

# 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

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
