######## 开始配置 ###########
apache
mkdir /usr/local/apache2/conf/mod_jk

配置httpd.conf 文件
vi /usr/local/apache2/conf/httpd.conf
修改
DocumentRoot "/usr/local/tomcat6/webapps"
添加
Include conf/mod_jk/mod_jk.conf

mkdir /usr/local/apache2/conf/mod_jk
mod_jk.conf
<Directory ~ "/WEB-INF/">
        Order allow,deny
        Deny from all
</Directory>
<Location /jkstatus>
        Order deny,allow
        Deny from all
</Location>

LoadModule jk_module modules/mod_jk.so
<IfModule jk_module>
JkWorkersFile conf/mod_jk/workers.properties
JkMountFile conf/mod_jk/uriworkermap.properties
JkShmFile logs/mod_jk.shm
JkLogFile logs/mod_jk.log
JkLogLevel warn
</IfModule>

创建并配置workers.properties文件
vi /usr/local/apache2/conf/mod_jk/workers.properties

ps = /
worker.list=loadbalance,jkstatus
###### tomcat worker1 ######
worker.worker1.port=8009
worker.worker1.host=127.0.0.1
worker.worker1.type=ajp13
worker.worker1.lbfactor=1

###### tomcat worker2 ######
worker.worker2.port=8009
worker.worker2.host=192.168.128.129
worker.worker2.type=ajp13
worker.worker2.lbfactor=1

worker.loadbalance.type=lb
worker.retries=3
worker.loadbalance.balance_workers=worker1,worker2
worker.loadbalance.sticky_session=1
sticky_session_force=false
# 如果某台服务故障，则转发请求到其它服务器(session已经丢失)
worker.jkstatus.type=status

创建并配置uriworkermap.properties
vi /usr/local/apache2/conf/uriworkermap.properties

/*.jsp=loadbalance
/*.do=loadbalance
/*.action=loadbalance
#/*把所有请求转发给tomcat处理
#!/*.gif把gif图片给apache处理其余的给tomcat处理(写在任意一行即可)

########### 配置tomcat ############
cd /usr/local/tomcat6/webapps
rm -rf docs host-manager/ manager/ ROOT/
保留examples作为测试用.

编辑/usr/local/tomcat6/conf/server.xml

<!--   <Connector port="8080" protocol="HTTP/1.1"
     70                connectionTimeout="20000"
     71                redirectPort="8443" />
     -->
     89     <!-- Define an AJP 1.3 Connector on port 8009 -->
           <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"
            maxThreads=”1000″ minSpareThreads=”25″       maxSpareThreads=”75″ acceptCount=”500″
            connectionTimeout=”10000″ disableUploadTimeout=”true” debug="0" enableLookups=”false” URIEncoding=”UTF-8″
           />  
           <!-- You should set jvmRoute to support load-balancing via AJP ie : -->
          <Engine name="Catalina" defaultHost="localhost" jvmRoute="worker1">
   
编辑131的server.xml
            <Engine name="Catalina" defaultHost="localhost" jvmRoute="worker2">           
# 注意jmvRoute要和worker1或worker2对应以用来判断session.
# 例如Session ID: 534A86863E157E7F0C9CBD489087CAFC.worker2

测试页面：
cat mem.jsp
<%
Runtime lRuntime = Runtime.getRuntime();
out.println("*** BEGIN MEMORY STATISTICS ***<br/>");
out.println("Free Memory: "+lRuntime.freeMemory()+"<br/>");
out.println("Max   Memory: "+lRuntime.maxMemory()+"<br/>");
out.println("Total Memory: "+lRuntime.totalMemory()+"<br/>");
out.println("Available Processors : "+lRuntime.availableProcessors()+"<br/>");
out.println("*** END MEMORY STATISTICS ***");
%>
# 对于apache的root和tomcat的webapps设置：
如果带目录访问则DocumentRoot和webapps指定的目录一样.
如果不带项目目录访问则tomcat需要设置Context指定访问路径/;
同时apache根目录设置和docBase一致.

如果要访问/examples/servlets/*必须添加
/examples/servlets/*=loadbalance
到uriworkermap.properties的任一行前或后。
不添加则不能访问，报404
