apache2 - Munin Dynazoom 无法在 Ubuntu 上运行

Question

我最近在我的机器上安装了 Munin。我让一切正常工作，数据实际上正在绘制在图表上! :)

但是，由于某种原因，当我单击每个单独的图表时，它会将我带到 dynazoom 页面，但它都是纯文本，没有图像:(

这是我的 apache.conf:

# Enable this for template generation
Alias /munin /var/cache/munin/www

# Enable this for cgi-based templates
#Alias /munin-cgi/static /var/cache/munin/www/static
#ScriptAlias /munin-cgi /usr/lib/munin/cgi/munin-cgi-html
#<Location /munin-cgi>
#       Order allow,deny
#       Allow from localhost 127.0.0.0/8 ::1
#       AuthUserFile /etc/munin/munin-htpasswd
#       AuthName "Munin"
#       AuthType Basic
#       require valid-user
#</Location>

<Directory /var/cache/munin/www>
        Order allow,deny
        # Allow from localhost 127.0.0.0/8 ::1
        Allow from all
        Options None
        AllowOverride 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>

# Enables fastcgi for munin-cgi-html if present
#<Location /munin-cgi>
#    <IfModule mod_fastcgi.c>
#        SetHandler fastcgi-script
#    </IfModule>
#</Location>

#<Location /munin-cgi/static>
#       SetHandler None
#</Location>

# Enables fastcgi for munin-cgi-graph if present
ScriptAlias /munin-cgi/munin-cgi-graph /usr/lib/munin/cgi/munin-cgi-graph
<Location /munin-cgi/munin-cgi-graph>
        Order allow,deny
        Allow from localhost 127.0.0.0/8 ::1
        # AuthUserFile /etc/munin/munin-htpasswd
        # AuthName "Munin"
        # AuthType Basic
        # require valid-user
        <IfModule mod_fcgid.c>
            SetHandler fcgid-script
        </IfModule>
        <IfModule !mod_fcgid.c>
            SetHandler cgi-script
        </IfModule>
</Location>

ScriptAlias /munin-cgi/munin-cgi-html /usr/lib/munin/cgi/munin-cgi-html
<Location /munin-cgi/munin-cgi-html>
        Order allow,deny
        Allow from localhost 127.0.0.0/8 ::1
        # AuthUserFile /etc/munin/munin-htpasswd
        # AuthName "Munin"
        # AuthType Basic
        # require valid-user
        <IfModule mod_fcgid.c>
            SetHandler fcgid-script
        </IfModule>
        <IfModule !mod_fcgid.c>
            SetHandler cgi-script
        </IfModule>
</Location>

有什么原因导致此功能无法正常工作吗？如果我没有提供足够的信息，请告诉我。谢谢

我在 Ubuntu 14.04 上遇到了同样的问题。

通过检查/var/log/apache2/error.log我发现脚本提示缺少模块:

Can't locate CGI/Fast.pm in @INC (you may need to install the CGI::Fast module) (@INC contains: /etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18 /usr/local/lib/site_perl) at /usr/lib/munin/cgi/munin-cgi-graph line 36.

我确实安装了 CGI::Fast 模块来解决这个问题:

sudo apt-get install libcgi-fast-perl

不需要任何重写规则，如另一个答案中所示。 Ubuntu 14.04 中的软件包已正确配置路径名。
