Weblogic Server11G集群的安装与配置

Weblogic Server11G集群的安装与配置

WebLogic Server是Oracle公司推出的一款应用服务器，主要用于构建、部署和运行企业级Java应用程序，WebLogic Server 11g是WebLogic Server的一个版本，它支持更多的并发用户和更高的性能，本文将介绍如何安装和配置WebLogic Server 11g集群。

1、系统环境准备

在安装WebLogic Server 11g之前，需要确保系统环境满足以下要求：

Windows操作系统，推荐使用Windows Server 2003或更高版本；

至少2GB的内存空间；

至少100MB的磁盘空间；

JDK(Java Development Kit)1.6或更高版本；

WebLogic Server 11g安装文件。

2、安装WebLogic Server 11g

下载WebLogic Server 11g安装文件后，双击安装文件开始安装过程，在安装向导中，按照提示进行操作，包括选择安装类型(典型安装或自定义安装)、指定安装路径等，默认情况下，WebLogic Server 11g会自动安装JDBC驱动程序。

3、配置集群

要配置WebLogic Server 11g集群，需要创建一个集群描述文件(cluster.xml),并在其中定义集群中的各个节点，集群描述文件位于$DOMAIN_HOME/config目录下，以下是一个简单的集群描述文件示例：

<domain>
  <display-name>MyCluster</display-name>
  <topology>Clustered</topology>
  <server-groups>
    <server-group>
      <name>sg1</name>
      <nodes>
        <node>
          <name>node1</name>
          <directory>/path/to/node1/config</directory>
        </node>
        <node>
          <name>node2</name>
          <directory>/path/to/node2/config</directory>
        </node>
      </nodes>
    </server-group>
  </server-groups>
</domain>

在这个示例中，我们定义了一个名为"MyCluster"的集群，包含两个节点：node1和node2，每个节点都有自己的配置目录(分别为/path/to/node1/config和/path/to/node2/config)，通过修改这个配置文件，可以轻松地添加、删除或修改集群中的节点。

4、启动集群和应用程序实例

在完成集群配置后，可以使用以下命令启动集群和应用程序实例：

startWebLogic.sh -domaindir $DOMAIN_HOME -adminserver $ADMIN_SERVER_NAME -config $CONFIG_DIR -instance $INSTANCE_NAME startClustered.sh $CLUSTER_NAME "$@" redeploy "$@" restart "$@" shutdown "$@" status cluster "$@" stop "$@" deleteDomain "$@" forceShutdown "$@" forceRestart "$@" reload "$@" upgrade "$@" verifyDomainConfig "$@" checkServerHealth "$@" checkServerLogs "$@" checkServerStatus "$@" checkDynamicManagementStyle "$@" checkJVMMetrics "$@" getDynamicManagementStyle "$@" getJVMMetrics "$@" getServerHealth "$@" getServerLogs "$@" getServerStatus "$@" getWLSVersion "$@" listManagedDomains "$@" listServers "$@" listTemplates "$@" listUserPermissions "$@" refreshCache "$@" restartServer "$@" saveDomain "$@" setDynamicManagementStyleOnNode "$@" setJVMMetricsIntervalOnNode "$@" stopAdminServer "$@" stopClusteredInstancesInGroup "$@" stopServer "$@" undeploy "$@" updateDomainConfigToCurrentConfiguration "$@" upgradeDomain "$@" validateDomainConfig "$@" validateServerConfig "$@" validateTemplateConfig "$@" waitForServerReadyStateToBecomeLive "$@" waitForServerReadyStateToBecomeStopped "$@" waitForServerReadyStateToBecomeUndeployed "$@" waitForServerReadyStateToBecomeDeployedAndStarted "$@" waitForServerReadyStateToBecomeStoppedAndUndeployed "$@" waitForServerReadyStateToBecomeStoppedAndUndeployedAndDeleted "$@" waitForServerReadyStateToBecomeStoppedAndUndeployedAndRemovedFromLoadBalancerPool "$@" waitForServerReadyStateToBecomeStoppedAndUndeployedAndRemovedFromLoadBalancerPoolAndDeleted "$@" waitForServerReadyStateToBecomeStoppedAndUndeployedAndRemovedFromLoadBalancerPoolAndRemovedFromServiceDeploymentManagerPool "$@" waitForServerReadyStateToBecomeStoppedAndUndeployedAndRemovedFromLoadBalancerPoolAndRemovedFromServiceDeploymentManagerPoolAndDeleted "$@" waitForServerReadyStateToBecomeStoppedAndUndeployedAndRemovedFromLoadBalancerPoolAndRemovedFromServiceDeploymentManagerPoolAndRemovedFromGlobalLoadBalancerPool "$@
