Debian 7.5 Nginx/1.6.0 PHP 5.6.0RC2 (fpm-fcgi)（构建于：2014 年 7 月 11 日 08:17:52）Munin v2.0.21-2
几天来我一直在网上寻找问题的答案，但似乎没人知道该怎么做。我启动并运行了 Munin，但 Munin 动态图形缩放 (dynazoom) 不起作用，这似乎是 cgi 的问题。我已经使用 spawnfcgi 测试了 lighttpd 和 apache 上的 Munin，一切正常，但 php5-fpm 不行。缩放屏幕上的图形可以显示，但 php5-fpm 不行，它只显示一个损坏的图像链接，就像这张图片一样http://serversupportforum.de/forum/attachments/monitoring/4901d1373968950-munin-dynazoom-funktioniert-nicht-1592281191.png“Munin 动态图缩放（dynazoom）”
现在很多人都在使用 Nginx 和 php-fpm，所以我认为这对很多人来说会很有帮助。例如：https://stackoverflow.com/questions/18645812/munin-dynamic-graph-zoom-dynazoom-not-working-centos6-nginx-php-fpm

Munin 配置文件：

# 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.

#
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.

## IPv6 host. note that the ip adress has to be in brackets

## Then we want totals...
# [foo.com;Totals] #Force it into the "foo.com"-domain...
# update no # Turn off data-fetching for this "host".
#
# # The graph "load1". We want to see the loads of both machines...
# # "fii=fii.foo.com:load.load" means "label=machine:graph.field"
# load1.graph_title Loads side by side
# load1.graph_order fii=fii.foo.com:load.load fay=fay.foo.com:load.load
#
# # The graph "load2". Now we want them stacked on top of each other.
# load2.graph_title Loads on top of each other
# load2.dummy_field.stack fii=fii.foo.com:load.load fay=fay.foo.com:load.load
# load2.dummy_field.draw AREA # We want area instead the default LINE2.
# load2.dummy_field.label dummy # This is needed. Silly, really.
#
# # The graph "load3". Now we want them summarised into one field
# load3.graph_title Loads summarised
# load3.combined_loads.sum fii.foo.com:load.load fay.foo.com:load.load
# load3.combined_loads.label Combined loads # Must be set, as this is
# # not a dummy field!
#
## ...and on a side note, I want them listen in another order (default is
## alphabetically)
#
# # Since [foo.com] would be interpreted as a host in the domain "com", we
# # specify that this is a domain by adding a semicolon.
# [foo.com;]

allow ^::1$
# If you have installed the Net::CIDR perl module, you can use one or more

# *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 127.0.0.1
# And which port

答案1
你的参数有误fastcgi_pass，它应该将请求传递给 spawn-fcgi，就像munin 的 wiki 上说不是 php-fpm。
对于 Ubuntu/Debian：
sudo apt-get install spawn-fcgi
spawn-fcgi -s /var/run/munin/fcgi-graph.sock -U www-data -u www-data -g www-data /usr/lib/munin/cgi/munin-cgi-graph
并且不要忘记修复 nginx 位置并随后重新启动它：
location ^~ /munin-cgi/munin-cgi-graph/ {
access_log off;
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;
}
