Question

我安装了3台服务器和Ubuntu，我想配置Tomcat负载平衡。

Server A = 10.0.0.1,
Server B = 10.0.0.2,
Server C = 10.0.0.3

我已将域指向服务器A，该服务器已安装Apache和Mod_JK。服务器B和C有Apache Tomcat 8.下面是我的workers.properties文件的详细信息

workers.apache_log=/var/log/apache2 worker.list=tomcatlb,status
worker.stat1.type=status

worker.tomcat1.type=ajp13 worker.tomcat1.host=10.0.0.2 #put your app
host here worker.tomcat1.port=8009 worker.tomcat2.type=ajp13 
worker.tomcat2.host=10.0.0.3 worker.tomcat2.port=8009

worker.tomcat1.lbfactor=1  worker.tomcat2.lbfactor=1 

worker.tomcatlb.type=lb
worker.tomcatlb.balance_workers=tomcat1,tomcat2

worker.list=jkstatus worker.jkstatus.type=status

我还在Apache Tomcat的server.xml中使用了jvmRounte名称作为tomcat1和tomcat2。

我还在server.xml中添加了以下行

      <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">

        <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="6"> 

        <Channel className="org.apache.catalina.tribes.group.GroupChannel">
        <Membership     className="org.apache.catalina.tribes.membership.McastService"
        address="228.0.0.4"
        port="45564" frequency="500"
        dropTime="3000"/> 

        <Sender     className="org.apache.catalina.tribes.transport.ReplicationTransmitter">

        <Transport     className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>

        </Sender> 

        <Receiver     className="org.apache.catalina.tribes.transport.nio.NioReceiver"
        address="auto" port="4001" autoBind="100"
        selectorTimeout="5000" maxThreads="6"/> 

        <Interceptor     className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>

        <Interceptor     className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interc    eptor"/>
        <Interceptor     className="org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor"/>


        </Channel>

apache配置有以下行

 RewriteEngine on
    RewriteRule ^/$ /test [PT,L]
    JkMount /* tomcatlb

apache通过mod_jk将请求重定向到Tomcat并且工作正常但是当一个tomcat发生故障时，它应该将请求重定向到另一个tomcat，而不是我必须重新定位，因为它不会复制会话。

Answer 1

我看到你失踪了 stickysession = JSESSIONID | jsessionid lbmethod = byrequests nofailover =关闭connectiontimeout = 5 timeout = 30

Answer 2

只是为了确定：这些实际上是单独的行：

worker.tomcat1.type=ajp13 worker.tomcat1.host=10.0.0.2

Answer 3

此外：是否故意，您的工作人员属性中缺少10.0.0.1？
