apache tomcat 整合集群设置
修改apache的conf目录下的httpd.conf文件，在最后加上一行
Include /usr/local/apache/conf/mod_jk2.conf
然后在/usr/local/apache/conf目录下创建 mod_jk2.conf 文件
LoadModule jk_module modules/mod_jk.so
JkWorkersFile /usr/local/apache/conf/workers2.properties
JkLogFile /usr/local/apache/logs/mod_jk.log
# Set the jk log level
JkLogLevel info
# 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"
JkMount /feedback* loadbalancer
JkMount /dac*loadbalancer
JkMount /* another
JkUnMount /*.jpg loadbalancer
JkUnMount /*.gif loadbalancer
JkUnMount /*.swf loadbalancer
JkUnMount /*.bmp loadbalancer
JkUnMount /*.png loadbalancer
这里配置了两个tomcat服务器，一个是loadbalancer,另一个是another，
然后在/usr/local/apache/conf目录下创建workers2.properties，指定两个tomcat的端口相应信息
workers.tomcat_home=/root/software/apache-tomcat-6.0.18
workers.java_home=/root/software/jdk1.6
worker.list=loadbalancer,another
# Define the first node...
worker.loadbalancer.port=8111
worker.loadbalancer.host=localhost
worker.loadbalancer.type=ajp13
# Define the 2nd node...
worker.another.port=8222
worker.another.host=localhost
worker.another.type=ajp13
loadbalancer 的ajp转发端口是8111，host是localhost，用的是ajp13协议转发，
aonther的ajp转发端口是8222，host是localhost，用的是ajp13协议转发，
然后loadbalancer这台tomcat服务器需要在server.xml修改一行，
把
<Engine name="Catalina" defaultHost="localhost"> 改为
<Engine name="Catalina" defaultHost="localhost" jvmRoute="loadbalancer">
这里的worker.loadbalancer.port=8111指定的端口是server.xml的
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8111" protocol="AJP/1.3"redirectPort="8443" />
这里的端口
同理another tomcat服务器也需要相应修改。
刚开始连不上是因为端口配错了，配成tomcat的连接端口去了。
