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

# 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.

# If you have installed the Net::CIDR perl module, you can use one or more

# 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

sudo munin–node–configure —shell —families=contrib,auto | sh –x
|
或者，自己创建软连接即可。
