第八组TOMCAT群集实现负载均衡.ppt

TOMCAT群集实现负载均衡1.环境介绍2.实验方案3.实现过程在配置文件的末尾加上：
ProxyRequestsOff
ProxyPass/balancer://myclusterstickysession=jsessionidnofailover=On
<Proxybalancer://mycluster>
BalancerMemberhttp://127.0.0.1:9080
BalancerMemberhttp://127.0.0.1:10080
</Proxy>
<Location/balancer-manager>
SetHandlerbalancer-manager
OrderDeny,Allow
Denyfromall
Allowfromall
</Location>
<Location/server-status>
SetHandlerserver-status
OrderDeny,Allow
Denyfromall
Allowfromall
</Location>

3.实现过程Tomcat1的配置：
<Serverport="9005"shutdown="SHUTDOWN">

<Connectorport="9080"protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"/>

<Connectorport="9009"protocol="AJP/1.3"redirectPort="8443"/>

<Hostname="localhost"appBase="webapps"
unpackWARs="true"autoDeploy="true"
xmlValidation="false"xmlNamespaceAware="false">
添加在<Host></Host>之间
