从 Ubuntu 12 升级到 14.04 后，我的 Munin 设置停止工作。
我尝试遵循这里给出的建议
重新加载并重新启动 apache、重新启动 munin 和 munin-node - 但仍然没有成功。
这是我的配置文件：
/etc/munin/apache.conf
Alias /munin /var/cache/munin/www
<Directory /var/cache/munin/www>
# Updated conf to apache 2.4 standard https://askubuntu.com/questions/539064/munin-404-after-upgrading-to-14-04
Require local
Require MYIP1
Require MYIP2
# Options None
# This file can be used as a .htaccess file, or a part of your apache
# config file.
#
# For the .htaccess file option to work the munin www directory
# (/var/cache/munin/www) must have "AllowOverride all" or something
# close to that set.
#
# AuthUserFile /etc/munin/munin-htpasswd
# AuthName "Munin"
# AuthType Basic
# require valid-user
# This next part requires mod_expires to be enabled.
#
# Set the default expiration time for files to 5 minutes 10 seconds from
# their creation (modification) time. There are probably new files by
# that time.
#
<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault M310
</IfModule>
</Directory>
/etc/munin/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
# (Exactly one) directory to include all files from.
#
includedir /etc/munin/munin-conf.d
# Make graphs show values per minute instead of per second
#graph_period minute
# Graphics files are normaly generated by munin-graph, no matter if
# the graphs are used or not. You can change this to
# on-demand-graphing by following the instructions in
# http://munin.projects.linpro.no/wiki/CgiHowto
#
#graph_strategy cgi
# 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 /cgi-bin/munin-cgi-graph
# munin-graph runs in parallel, the number of concurrent processes is
# 6. If you want munin-graph to not be parallel set to 0. If set too
# high it will slow down munin-graph. Some experiments are needed to
# determine how many are optimal on your system. On a multi-core
# system with good SCSI disks the number can probably be quite high.
#
#max_graph_jobs 6
# Drop [email protected] and [email protected] an email everytime
# something changes (OK -> WARNING, CRITICAL -> OK, etc)
#contact.someuser.command mail -s "Munin notification" [email protected]
#contact.anotheruser.command mail -s "Munin notification" [email protected]
#
# For those with Nagios, the following might come in handy. In addition,
# the services must be defined in the Nagios server as well.
#contact.nagios.command /usr/bin/send_nsca nagios.host.comm -c /etc/nsca.conf
# a simple host tree
[my.host1.com]
address 127.0.0.1
use_node_name yes
[my.host2.com]
address 10.1.1.23
use_node_name yes
[my.host3.com]
address 10.1.1.24
use_node_name yes
#
# A more complex example of a host tree
#
## First our "normal" host.
# [fii.foo.com]
# address foo
#
## Then our other host...
# [fay.foo.com]
# address fay
#
## 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;]
# node_order Totals fii.foo.com fay.foo.com

munin 文件位于 /var/cache/munin/www。如果您能提供任何关于下一步的想法，我们将不胜感激。
