在 debian 6 上安装 Munin 并获得 403

Question

我已经在我的服务器上安装了 Munin，但是当我尝试访问 mypage.com/munin 时出现 403 错误：禁止访问，您无权访问此服务器上的 /munin/。

我的配置如下：

• node 和 master 安装在同一台服务器上。

• 文件/etc/munin/apache.conf有如下配置

   Alias /munin /var/cache/munin/www
   <Directory /var/cache/munin/www>
      Order allow,deny
      Allow from all
      Options FollowSymLinks SymLinksIfOwnerMatch
      <IfModule mod_expires.c>
         ExpiresActive On
         ExpiresDefault M310
      </IfModule>
  </Directory>
  

• munin conf 是 /etc/munin/munin.conf

  dbdir   /var/lib/munin
  htmldir /var/cache/munin/www
  logdir /var/log/munin
  rundir  /var/run/munin
  ....
  [myserver]
      address 127.0.0.1
      use_node_name yes
  

• 而节点配置（/etc/munin/munin-node.conf）是默认配置。

在文件夹 /var/cache/munin/www 中没有生成图表，因为这个文件夹是空的，而且没有生成日志，我不明白为什么。

使用新版Munin 2.0！

创建和编辑 /etc/apt/sources.list.d/backports.list 并添加：

deb http://backports.debian.org/debian-backports squeeze-backports main

更新存储库，然后安装 munin

# apt-get update
# apt-get install munin -t squeeze-backports

此版本的 Munin 默认使用 CGI 生成 HTML 和 GRAPH。所以在配置虚拟主机之前一定要这样做：

# apt-get install libapache2-mod-fcgid
# a2enmod fcgid

配置您的虚拟主机：

    <VirtualHost *:80>
        DocumentRoot /var/cache/munin/www
        ServerName munin.example.com
        Alias /static /etc/munin/static
        # Rewrites
        RewriteEngine On
        # HTML
        RewriteCond %{REQUEST_URI} !^/static
        RewriteCond %{REQUEST_URI} .html$ [or]
        RewriteCond %{REQUEST_URI} =/
        RewriteRule ^/(.*)           /usr/lib/munin/cgi/munin-cgi-html/$1 [L]
        # Images
        # - remove path to munin-cgi-graph, if present
        RewriteRule ^/munin-cgi/munin-cgi-graph/(.*) /$1
        RewriteCond %{REQUEST_URI}                 !^/static
        RewriteCond %{REQUEST_URI}                 .png$
        RewriteRule ^/(.*)  /usr/lib/munin/cgi/munin-cgi-graph/$1 [L]
        # Ensure we can run (fast)cgi scripts
        ScriptAlias /munin-cgi/munin-cgi-graph /usr/lib/munin/cgi/munin-cgi-graph

最后，开始享受新版本的穆宁

# a2ensite munin
# /etc/init.d/apache2 reload

现在您可以在几分钟后通过http://munin.example.com 访问munin。让munin先收集一些数据。
