Question

我最近在我的机器上安装了Munin。我得到了一切工作，数据实际上是在图表上绘制的！：）

但是，出于某种原因，当我点击每个单独的图表时，它会将我带到dynazoom页面，但它都是没有图像的纯文本：（

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>

为什么这不起作用？如果我没有提供足够的信息，请告诉我。谢谢

Answer 1

启用apache2 cgi（或cgid）会使dynazoom工作。

sudo a2enmod cgi; sudo service apache2 restart

Answer 2

我在Ubuntu 14.04上遇到了同样的问题。

通过检查/var/log/apache2/error.log我发现脚本抱怨缺少模块：

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模块来解决问题：

sudo apt-get install libcgi-fast-perl

不需要任何重写规则，如另一个答案所示。 Ubuntu 14.04中的软件包正确配置了路径名。

Answer 3

除ermannob的答案外;我的apache2 error.log报告了

  AH01797: client denied by server configuration: /usr/lib/munin/cgi/munin-cgi-graph

这阻止了我在操作系统中弄乱文件权限并导致我查看apache配置。所需要的只是改变

<Location /munin-cgi/munin-cgi-graph>
    Order allow,deny
    Allow from localhost 127.0.0.0/8 ::1
    ...

在/etc/apache2/conf-enabled/munin.conf中，到

<Location /munin-cgi/munin-cgi-graph>
    Require all granted
    Options FollowSymLinks SymLinksIfOwnerMatch

我不需要安装任何fastcgi软件包并遵循教程here。他们建议直接将配置添加到apache.conf文件中，然后放宽conf-enabled / munin.conf文件中的权限（对于/ munin，/ munin-cgi / munin-cgi-graph和/ munin-cgi / munin-cgi-html）就足够了。我省略了对apache.conf的更改。

Answer 4

运行Ubuntu 14.04时，我通过将/etc/apache2/conf-available/munin.conf中的apache配置从2.2样式更新为2.4来修复我自己的服务器

示例：

<Directory /var/cache/munin/www>
Order allow,deny
Allow from localhost 127.0.0.0/8 ::1
....
</Directory>

需要更改为

<Directory /var/cache/munin/www>
# Order allow,deny
# Allow from localhost 127.0.0.0/8 ::1
Require all granted
....
</Directory>

或者你可以做到

Require host localhost

或

Require ip 127.0.0.0/8 ::8

请参阅有关更改的{apache文档here。当我意识到这一点时，我已经完成并安装了FastCGI和此线程中列出的perl模块。需要对munin.conf中看到的所有位置/目录区域进行此更改。

我在Debian 8上遇到了同样的问题。我已经编辑了/etc/munin/apache24.conf这样的文件：

Alias /munin /var/cache/munin/www
<Directory /var/cache/munin/www>
   Require all granted
   Options FollowSymLinks SymLinksIfOwnerMatch
</Directory>

ScriptAlias /munin-cgi/munin-cgi-graph /usr/lib/munin/cgi/munin-cgi-graph
<Location /munin-cgi/munin-cgi-graph>
    Require all granted
    Options FollowSymLinks SymLinksIfOwnerMatch
        <IfModule mod_fcgid.c>
            SetHandler fcgid-script
        </IfModule>
        <IfModule !mod_fcgid.c>
            SetHandler cgi-script
        </IfModule>
</Location>

然后我安装了前面提到的libapache2-mod-fcgid。

在munin节点重启后，它正常工作。

Answer 6

我在Ubuntu 14.04 LTS中遇到过相同的行为。原因是dynazoom页面中的图像URL错误地使用了/cgi-bin/munin-cgi-graph/而不是/munin-cgi/munin-cgi/graph/，因此我没有在代码中搜索到修复此错误，而是使用快速重写规则解决了这个问题：

RewriteRule ^/cgi-bin/munin-cgi-graph/(.*) /$1

希望这有帮助

Answer 7

您应该更改关于munin-cgi-graph的配置部分，设置与主要部分相同的权限。这是您的配置：

# 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>

将其更改为：

# 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
    Allow from all
    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>

另外我必须安装libcgi-fast-perl包，这样做：

sudo apt-get install libcgi-fast-perl

检查/var/log/apache2/error.log对我帮助很大。

Answer 8

在我https://bugs.launchpad.net/ubuntu/+source/munin/+bug/1258026和http://munin-monitoring.org/wiki/MuninConfigurationMasterCGI工作的情况下。

唯一有问题的部分是放置Apache虚拟主机配置的位置，结果是将其置于/etc/apache2/sites-enabled/001-munin.conf工作。

Munin Dynazoom没有在Ubuntu上工作
