我正在尝试在我的服务器中安装 Munin，并配置 Web 界面以在子域中工作。我已经配置了子域stats.mysite.com并创建了文件/etc/apache2/sites-available/stats.mysite.com：
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin [email protected]
ServerName stats.mysite.com
ServerAlias www.stats.mysite.com
DocumentRoot /var/cache/munin/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
LogLevel notice
CustomLog /var/log/apache2/access.log combined
ErrorLog /var/log/apache2/error.log
ServerSignature On
</VirtualHost>
然后，我使用以下命令来启用我的网站：
a2ensite stats.mysite.com
并重新启动Apache：
sudo /etc/init.d/apache2 restart
但它不起作用。当我stats.mysite.com在浏览器上访问时，它显示的内容mysite.com。我做错了吗？如果有人能帮助我，我将不胜感激。

#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.

# # The graph "load1". We want to see the loads of both machines...

# 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.dummy_field.draw AREA # We want area instead the default LINE2.
# load2.dummy_field.label dummy # This is needed. Silly, really.

#
## ...and on a side note, I want them listen in another order (default is

查看输出中的 [WARN]apache2ctl -S并查看 stats.mysite.com 的配置文件，我猜测您有NameVirtualHost *:80多次这样的情况，这很可能会导致问题。
从 stats.mysite.com conf 文件和任何其他站点特定文件中删除它NameVirtualHost *:80，并将其仅放置一次在 /etc/apache2 中主 apache2.conf 文件末尾附近。
