当在干净的Ubuntu服务器12.04中设置2个tomcat6实例集群时，有点困惑。 我没有安装默认的tomcat6我用tomcat6-user的tomcat6-instance-create来创build2个实例。 我正在使用blogs.encodo.ch教程，不幸的是，我还没有遇到任何使用Ubuntu的教程如何configurationapache2像ubuntu 12.o4。 我的意思是，ubuntu使用的sites-available/enabled文件夹和mods-available/enabled 。
我已经安装了libapache2-mod-jk和mods-enabled了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
这里是/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，负载平衡本身似乎工作。 只是我无法通过xxx.xxx.xxx.xxx/jk-status或xxx.xxx.xxx.xxx/jk-manager访问负载平衡器pipe理器页面。 在mod_jk.log文件中也有这个条目

问题1 ：我错过了什么？ 为什么它不起作用？
问题2 ： #DocumentRoot /var/www真的有必要？
问题3 ：jk.conf文件的IfModule中的JkMount和virtualhost的JkMount什么区别
请帮助我正确设置。 谢谢
