Apache2.4 + Tomcat6集群配置笔记
一、安装Apache
1、修改httpd.conf中的路径c:/Apache24为Apache安装包的路径，如:D:/httpd-2.4.12/Apache24
2、进入Apache安装目录下的bin目录：
httpd.exe-kinstall
3、启动服务httpd.exe-w-n"Apache2.4"-kstart
（卸载服务scdeleteApache2.4）
二、配置Apache
1、打开conf/httpd.conf文件，加载以下模块
LoadModuleproxy_modulemodules/mod_proxy.so
LoadModuleproxy_ajp_modulemodules/mod_proxy_ajp.so
LoadModulerewrite_modulemodules/mod_rewrite.so
LoadModuleproxy_balancer_modulemodules/mod_proxy_balancer.so
LoadModuleproxy_connect_modulemodules/mod_proxy_connect.so
LoadModuleproxy_ftp_modulemodules/mod_proxy_ftp.so
LoadModuleproxy_http_modulemodules/mod_proxy_http.so
LoadModuleslotmem_shm_modulemodules/mod_slotmem_shm.so
LoadModulespeling_modulemodules/mod_speling.so
LoadModulessl_modulemodules/mod_ssl.so
LoadModulelbmethod_byrequests_modulemodules/mod_lbmethod_byrequests.so
2、去掉Includeconf/extra/httpd-vhosts.conf前面的注释符
3、在文件末尾添加反向代理
ProxyRequestsOff
<proxybalancer://cluster>
BalancerMemberajp://127.0.0.1:11007loadfactor=1route=tomcat1
BalancerMemberajp://127.0.0.1:11008loadfactor=1route=tomcat2
BalancerMemberajp://127.0.0.1:11009loadfactor=1route=tomcat3
</proxy>
4、打开conf/extra/httpd-vhosts.conf文件，配置虚拟站点
<VirtualHost*:80>
ServerNamelocalhost
ServerAliaslocalhost
ProxyPass/balancer://cluster/stickysession=jsessionidnofailover=On
ProxyPassReverse/balancer://cluster/
ErrorLog"logs/lbtest-error.log"
CustomLog"logs/lbtest-access.log"common
</VirtualHost>
三、配置tomcat
1、复制3个tomcat
2、修改tomcat2的server.xml
<Serverport="8005"shutdown="SHUTDOWN">把port改为8006
<ConnectorconnectionTimeout="20000"port="8080"protocol="HTTP/1.1"redirectPort="8443"/>把port改为8090
<Connectorport="11008"protocol="AJP/1.3"redirectPort="8443"/>把port改为11008
<EnginedefaultHost="localhost"name="Catalina">添加jvmRoute="tomcat2"，在tomcat1中同样添加jvmRoute="tomcat1"
打开<Clusterclassname="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>注释
3、修改tomcat3的server.xml，同tomcat2，把port改为11009，添加jvmRoute="tomcat3"，保证3个tomcat的端口都不相同，并且AJP的的端口和httpd.conf文件中配置的代理端口一致。
四、在项目中的web.xml文件的<web-app>节点下加入<distributable/>
