Tomcat Cluster Farm Deployer 问题

Question

我已经mod_jk在 ubuntu 服务器上设置了 apache-tomcat 集群。我在FarmDeployer将 war 文件部署到集群中的其他 Web 服务器时遇到了一些问题，我希望它能像我发布的那样工作并使 FarmDeployer 在这里工作。

战争部署器与帖子中的以下配置完美配合，但不能可靠地工作，因为它有时会在访问页面时出现 404 错误：

 <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

    <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster">
        <Channel className="org.apache.catalina.tribes.group.GroupChannel">
            <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                  address="192.168.1.4"
                  port="4000"
                  selectorTimeout="100"
                  maxThreads="6"/>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.StaticMembershipInterceptor">
                <Member className="org.apache.catalina.tribes.membership.StaticMember"
                      port="4000"
                      securePort="-1"
                      host="192.168.1.2"
                      domain="staging-cluster"
                      uniqueId="{0,1,2,3,4,5,6,7,8,9}"/>
            </Interceptor>
        </Channel>
        <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
            tempDir="/usr/share/tomcat/temp/"
            deployDir="/usr/share/tomcat/webapps/"
            watchDir="/usr/share/tomcat/watch/"
            watchEnabled="true"/>
    </Cluster>
  </Host>

以下是完美适用于 HA 和 LB 集群的配置（来自 tomcat cluster docs）。But it fails in Farm Deployer并且日志中没有任何说明农场部署程序不工作的原因。

<Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="8">

  <Manager className="org.apache.catalina.ha.session.DeltaManager" 

          expireSessionsOnShutdown="false"

          notifyListenersOnReplication="true"/>



  <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="4000" autoBind="100"

           selectorTimeout="5000" maxThreads="6"/>

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

    <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>

  </Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter=""/>

<Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

<ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>

<ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>

</Cluster>


<Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
            tempDir="/usr/share/tomcat/temp/"
            deployDir="/usr/share/tomcat/webapps/"
            watchDir="/usr/share/tomcat/watch/"
            watchEnabled="true"/>


</Host>

任何人都对如何使农场部署器与上述 HA 和 LB 配置完美配合有任何想法或任何工作配置？

谢谢！

更新：1

我根据您的配置配置了 3 个节点，但我无法使用域名（指向 LB）访问该站点，并且它提供了 tomcat ROOT 页面，但ip/myapp它正在呈现。

战争文件 myapp.war 已部署到所有服务器，但不会在管理器节点（部署 Web 服务器）以外的其他 2 个节点上提取。

登录其他 2 个网络服务器：

Answer 1

如何更新 3 个 Web 服务器？

执行与使用 2 个节点时相同的操作。

在部署节点上，再添加一个成员StaticMembershipInterceptor：

<Member className="org.apache.catalina.tribes.membership.StaticMember"
                          port="4002"
                          securePort="-1"
                          host="192.168.5.208"
                          domain="staging-cluster"
                          uniqueId="{0,1,2,3,4,5,6,7,8,9}"/>

在节点 3 上，创建一个如下所示的集群：

        <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster">
            <Channel className="org.apache.catalina.tribes.group.GroupChannel">

并复制一个 *.war 文件到watchdir部署节点上的目录，以下几行将出现在catalina.out：

无效或不可读的 WAR 文件：无效的 CEN 标头（错误签名）

部署到其他 2 个节点时，WAR 文件似乎已损坏。它多久发生一次？

除了 FarmDeployer 之外，是否有可能让 FarmDeployer 与来自 tomcat 集群文档的多播一起工作，这对我来说是完美的？

我想到了！原因是您没有为网络接口添加多播路由，因此无法在 Tomcat 节点之间发送/接收集群消息：

lsof -i :4000
COMMAND  PID   USER   FD   TYPE    DEVICE SIZE NODE NAME
java    9968 tomcat   37u  IPv6 121232775       TCP localhost:terabase (LISTEN)

请按以下步骤操作：

• 确保您的网络接口已启用多播：

  UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1

• 添加组播路由：

  route add -host 228.0.0.4 dev bond1

（您应该更改bond1为接收集群消息的网络接口）

测试ping -c 4 228.0.0.4对我不起作用。所以，我下载了多播测试工具，运行它，我看到以下响应：

./bin/multicast-test.sh -local 192.168.5.149 -group 228.0.0.4:45564

或者您可以使用lsof, netstat, ...

lsof -i :4000
COMMAND   PID   USER   FD   TYPE    DEVICE SIZE NODE NAME
java    11084 tomcat   37u  IPv6 121236631       TCP localhost:terabase (LISTEN)
java    11084 tomcat   59u  IPv6 121236830       TCP localhost:terabase->192.168.5.199:43519 (ESTABLISHED)
java    11084 tomcat   66u  IPv6 121236835       TCP localhost:55538->192.168.5.199:terabase (ESTABLISHED)

您已准备好使用多播配置 Tomcat 集群。

启用与文档中提到的相同的集群配置，但将<Receiver地址从“自动”更改为指定接口：

<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                      address="192.168.5.149"
                      port="4000"
                      autoBind="100"
                      selectorTimeout="5000"
                      maxThreads="6"/>

对集群中的所有节点执行相同的操作以查看它是否有效。

编辑 2

改进：我很高兴地使用多播配置在 Receiver 中将 auto 更改为 ip，当我将 war 文件放在部署程序 Web 服务器的 watch 目录中时，我在另一台 Web 服务器上看到了 myapp.war。问题是，war 仅在部署者 Web 服务器（创建目录）上提取，而不是在其他服务器上提取。

这意味着部署节点和其他节点之间的连接已经建立。您是否仍然收到相同的错误“无效或无法读取的 WAR 文件：无效的 CEN 标头（错误签名）”？每次？

java.util.zip.ZipException: invalid END header (bad central directory offset)

根据错误45851，您应该升级 Tomcat 版本（至少 6.0.19）并重试。我使用的是 6.0.29 版，正如您所见，它运行良好。

它需要在其他 Web 服务器上重新启动 tomcat，然后它会复制和提取，并且该站点可以使用 other-web-severs-ip/myapp 而不是域名（404 错误）。你把站点域名指向哪里，我把DNS中的站点域名指向LB，在所有同域名的tomcat web服务器中创建了一个虚拟主机

没有。看来你还没有彻底清除。无需在所有 Tomcat 节点中创建虚拟主机。

假设您在节点 1 上有 Apache HTTP 服务器和 Tomcat，IP 为 192.168.1.101。位于 1.102、1.103 的另外两个 Tomcat 节点。jvmRoute对应的有：tomcat1、tomcat2、tomcat3。

在mod_jk.confApache的HTTP服务器上：

LoadModule          jk_module modules/mod_jk.so

JkWorkersFile       /etc/httpd/conf/workers.properties
JkShmFile           /var/log/httpd/jk.shm

JkLogFile           /var/log/httpd/mod_jk.log
JkLogLevel          info
JkLogStampFormat    "[%a %b %d %H:%M:%S %Y] "

JkMount /myapp/*    cluster

该workers.properties是这样的：

worker.list = cluster

worker.tomcat1.port=8009        
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor=1

worker.tomcat2.port=8009        
worker.tomcat2.host=192.168.1.102
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor=1

worker.tomcat3.port=8009        
worker.tomcat3.host=192.168.1.103
worker.tomcat3.type=ajp13
worker.tomcat3.lbfactor=1

worker.cluster.type=lb
worker.cluster.balance_workers=tomcat1,tomcat2,tomcat3
worker.cluster.sticky_session=1

再试一次。
