WebSphere:为负载平衡问题合并插件cfg.xml

Question

我正在尝试合并和负载平衡几个独立的WebSphere 6.1 Express服务器。我使用这里提供的说明：

从多个节点合并插件cfg.xml文件http://www-01.ibm.com/support/knowledgecenter/SSEQTP_8.5.5/com.ibm.websphere.base.doc/ae/twsv_configsimplelb.html?lang=en

这里：

在多个应用程序服务器配置文件之间配置简单的负载平衡http://www-01.ibm.com/support/knowledgecenter/SSAW57_6.1.0/com.ibm.websphere.base.doc/info/aes/ae/twsv_configsimplelb.html

我将来自两个不同WAS服务器的两个plugin-cfg.xml文件合并为一个，更新了两个WAS服务器上的Web服务器设置以指向这个新文件，还更新了插件以使用新合并的文件。服务器启动，但我只收到发送到第一台WebSphere服务器的请求。我很确定我为<虚拟主机组>元素不正确，是这个问题的幕后推手。我想我需要把所有<虚拟主机>元素组合成一个<虚拟主机组>元素，并且还将所有<服务器>元素合并为一个<服务器群集>元素，但我只是猜测。

Answer 1

您的文件存在一些问题。

首先，您需要为两台服务器设置cloneId，如本文所述，配置一个唯一的HTTP会话克隆ID:

要使用管理控制台，完成以下步骤：

• 单击Servers > Server Types > WebSphere application servers > server_name
• 在"Container Settings"下，单击"Web Container Settings > Web container"
• 在"Additional Properties"下，单击"Custom properties > New"
• 在名称字段中输入HttpSessionCloneId，在值字段中输入服务器的唯一值
  唯一值的长度必须是8-9个字母数字字符。例如，test1234是一个有效的cloneID值
• 单击Apply或OK
• 单击Save将配置更改保存到主配置

然后，您实际上需要合并（而不是同时复制两者），plugin-cfg.xml的特定部分（我只是发布合并的部分，而不是整个文件）。所以您需要一个VirtualHostGroup、ServerCluster、UriGroup和Route。对于VirtualHostGroup，您只需要80和443个端口。

<VirtualHostGroup Name="default_host">
  <VirtualHost Name="*:80"/>
  <VirtualHost Name="*:443"/>
</VirtualHostGroup>
<ServerCluster CloneSeparatorChange="false" GetDWLMTable="false" IgnoreAffinityRequests="true" LoadBalance="Round Robin" Name="server1_custTestNode_Cluster" PostBufferSize="64" PostSizeLimit="-1" RemoveSpecialHeaders="true" RetryInterval="60">
  <Server CloneID="s111111" LoadBalanceWeight="1" ConnectTimeout="0" ExtendedHandshake="false" MaxConnections="-1" Name="custTestNode_server1" ServerIOTimeout="0" WaitForContinue="false">
     <Transport Hostname="websphere02" Port="9098" Protocol="http"/>
     <Transport Hostname="websphere02" Port="9475" Protocol="https">
        <Property Name="keyring" Value="E:eStorefrontCTireTestplugin/config/webserver1/plugin-key.kdb"/>
        <Property Name="stashfile" Value="E:eStorefrontCTireTestplugin/config/webserver1/plugin-key.sth"/>
     </Transport>
  </Server>
  <Server CloneID="s22222" LoadBalanceWeight="1" ConnectTimeout="0" ExtendedHandshake="false" MaxConnections="-1" Name="custTest2Node_server1" ServerIOTimeout="0" WaitForContinue="false">
     <Transport Hostname="websphere02" Port="9133" Protocol="http"/>
     <Transport Hostname="websphere02" Port="9491" Protocol="https">
        <Property Name="keyring" Value="E:eStorefrontCTireTestplugin/config/webserver1/plugin-key.kdb"/>
        <Property Name="stashfile" Value="E:eStorefrontCTireTestplugin/config/webserver1/plugin-key.sth"/>
     </Transport>
  </Server>
 <PrimaryServers>
   <Server Name="custTestNode_server1"/>
   <Server Name="custTest2Node_server1"/>
  </PrimaryServers>
</ServerCluster>
<UriGroup Name="default_host_server1_custTestNode_Cluster_URIs">
  <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/gatewayRMIWEB/*"/>
  <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/ccWEB/*"/>
  <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/ccStandAlone/*"/>
  <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/ivt/*"/>
  <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/monitorServerWEB/*"/>
  <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/customerInquiry/*"/>
  <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/storefrontAdminWEB/*"/>
  <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/storefrontB2BWEB/*"/>
  <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/storefrontB2CWEB/*"/>
 </UriGroup>
<Route ServerCluster="server1_custTestNode_Cluster" UriGroup="default_host_server1_custTestNode_Cluster_URIs" VirtualHostGroup="default_host"/>

我希望你明白。你必须测试它。你可以删除这些你不想处理的小便器，例如monitorServerWEB。如果它能路由到给定的服务器，测试的简单方法是为另一台服务器设置LoadBalanceWeight=0。我看到你已经在插件中启用了跟踪，所以它将为你提供插件如何匹配uri、vhost和服务器的更多细节。
