使用 mod_jk 在 ubuntu 12.04 上设置简单的 tomcat6 集群时出现混乱：状态页面不会显示

在干净的 ubuntu server 12.04 中设置 2 个 tomcat6 实例集群时，我有点困惑。我没有安装默认的，tomcat6我使用tomcat6-user'stomcat6-instance-create创建了 2 个实例。我正在使用博客教程，不幸的是我还没有遇到任何使用 ubuntu 的教程，了解如何apache2像 ubuntu 12.o4 那样配置。我的意思是，sites-available/enabled文件夹的结构以及mods-available/enabledubuntu 使用的结构。
我已经安装libapache2-mod-jk并mods-enabled有 jk.load、jk.conf。

server instance-1 uses port 8081 for http, port 8009 for ajp with jvmRoute="worker1" and instance-2 uses port 8082 for http, port 8010 for ajp with jvmRoute="worker2"

#/etc/apache2/workers.propeties
 worker.list=loadbalancer,jk-status

#setup instance-1
worker.instance-1.port=8009
worker.instance-1.host=localhost
worker.instance-1.type=ajp13
#worker.instance-1.lbfactor=50

#setup instance-2
worker.instance-2.port=8010
worker.instance-2.host=localhost
worker.instance-2.type=ajp13
#worker.instance-2.lbfactor=100

#setup the load-balancer
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=instance-1,instance-2
worker.loadbalancer.sticky_session=True
#worker.loadbalancer.sticky_session_force=True

# Status worker for managing load balancer
worker.status.type=jk-status

这是 /etc/apache2/mods-available/jk.conf

<IfModule jk_module>
    JkWorkersFile /etc/apache2/workers.properties

    JkLogFile /var/log/apache2/mod_jk.log

    JkLogLevel info

    JkShmFile /var/log/apache2/jk-runtime-status

    JkWatchdogInterval 60

    <Location /jk-status>
    # Inside Location we can omit the URL in JkMount
    JkMount jk-status
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1 xxx.xxx.xxx.xxx
    </Location>
    <Location /jk-manager>
    # Inside Location we can omit the URL in JkMount
    JkMount jk-manager
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1 xxx.xxx.xxx.xxx
    </Location>

    # Example for Mounting a context to the worker "balancer"
    # The URL syntax "a|b" instantiates two mounts at once,
    # the first one is "a", the second one is "ab".
    # JkMount /myapp|/* balancer

    # Example for UnMounting requests for all workers
    # using a simple URL pattern
    # Since: 1.2.26
    # JkUnMount /myapp/static/* *

    # Example for UnMounting requests for a named worker
    # JkUnMount /myapp/images/* balancer

    # Example for UnMounting requests using regexps
    # SetEnvIf REQUEST_URI "\.(htm|html|css|gif|jpg|js)$" no-jk

    # Example for setting a reply timeout depending on the requets URL
    # Since: 1.2.27
    # SetEnvIf Request_URI "/transactions/" JK_REPLY_TIMEOUT=600000

    # Example for disabling reply timeouts for certain request URLs
    # Since: 1.2.27
    # SetEnvIf Request_URI "/reports/" JK_REPLY_TIMEOUT=0
</IfModule>

这是我的虚拟主机

<VirtualHost *:80>
  ServerAdmin [email protected]
  ServerAlias live.myserver.com
  #DocumentRoot /var/www
  ServerName go2.myserver.com
  JkMount /* loadbalancer
  JkMount /status/* jk-status
  JkMount /jk-manager/* jk-status
  #Loglevel warn
  ErrorLog /var/log/apache2/go.myserver_error_log
  CustomLog /var/log/apache2/go.myserver_access_log combined
</VirtualHost>

编辑：经过几个小时的努力，负载平衡本身似乎已经起作用了。只是我无法通过xxx.xxx.xxx.xxx/jk-statusnor访问负载平衡器管理器页面。文件xxx.xxx.xxx.xxx/jk-manager中还有这些条目mod_jk.log

问题 1：我遗漏了什么？为什么它不起作用？

问题2：#DocumentRoot /var/www真的有必要吗？

问题 3： jk.conf 文件JkMount中的和中的有什么区别IfModuleJkMountvirtualhost

请帮助我正确设置。谢谢
