win7 系统apache+jboss的集群
1.下载Apache服务器：（http://www.apache.org），我下载的是apache_2.2.14-win32-x86-openssl-0.9.8k.msi，双击安装即可（若提示先删除的话说明电脑已安装http服务）。2.启动http服务，找到${http_home}/bin,点击ApacheMonitor.exe,在电脑右下角有一个apache的标志，右击->start,然后访问:127.0.0.1：80，出现It works! 说明成功。还有就是修改http的服务端口，默认是80端口，要修改的话在${http_home}/conf/http.conf下修改。
3.下载mod_jok.so，http://archive.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/，访问该网址，根据需要下载对应的mod_jok.so。我下载的是win32/jk-1.2.14/mod_jk-1.2.14-apache-2.0.54.so ,重命名为mod_jok.so。将该文件放在${http_home}/moudles下。
4.修改httpd.conf，导入mode_jk.conf ：Include conf/mod_jk.conf
5.在${http_home}/conf下新建mod_jk.conf
# Load mod_jk module. Specify the filename
# of the mod_jk lib you’ve downloaded and
# installed in the previous section
LoadModule jk_module modules/mod_jk.so
# Where to find workers.properties
JkWorkersFile conf/workers.properties
# Where to put jk logs
JkLogFile conf/mod_jk.log
# Set the jk log level
JkLogLevel error
# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# JkOptions indicate to send SSL KEY SIZE,
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
# JkRequestLogFormat set the request format
JkRequestLogFormat "%w %V %T"
JkMountFile conf/uriworkermap.properties
6.在${http_home}/conf下新建uriworkermap.properties
/memcached/*=LoadBalancer
#
# Mount jkstatus to /jkmanager
# For production servers you will need to
# secure the access to the /jkmanager url
#
/jkmanager=jkstatus
7.在${http_home}/conf下新建workers.properties
worker.list=LoadBalancer,jkstatus
worker.jkstatus.type=status
# Now we define the load-balancing behaviour
worker.LoadBalancer.type=lb
worker.LoadBalancer.balance_workers=node1,node2
worker.LoadBalancer.sticky_session=false
worker.LoadBalancer.method=R
worker.LoadBalancer.retries=2
#该port为jboss实例啊ajp端口
worker.node1.port=8109
worker.node1.host=localhost
worker.node1.type=ajp13
worker.node1.fail_on_status=500
worker.node1.cachesize=100
worker.node1.connection_pool_size=50
worker.node1.connection_pool_minsize=25
worker.node1.connection_pool_timeout=600
worker.node2.port=8209
worker.node2.host=localhost
worker.node2.type=ajp13
worker.node2.fail_on_status=500
worker.node2.cachesize=100
worker.node2.connection_pool_size=50
worker.node2.connection_pool_minsize=25
worker.node2.connection_pool_timeout=600
ps：解释一下workers.properties文件
当访问路径为 ip:80/memcached/*，apache将该请求分发到两个服务器node1、node2，node1、node2根据port、host等配置好
8.修改jboss的配置文件：修改/deploy/jboss-web.deployer/ META-INF/jboss-service.xml文件中以下配置为true：
<attribute name="UseJK">true</attribute>
修改/deploy/jboss-web.deployer/ server.xml中Engine的节点，增加jvmRoute属性：
<Engine name=“jboss.web” defaultHost=“localhost” jvmRoute=“” >
9.修改项目的web.xml文件：在末尾添加<distributable/>即可
启动在两个配置好的jboss，若访问路径为127.0.0.1：9000/memcached/index.action，127.0.0.1：9001/memcached/index.action，通过访问127.0.0.1/memcached/index.action也能访问成功，则说明成功
