Question

我正在尝试合并和负载平衡多个独立的WebSphere 6.1 Express服务器。我正在使用此处提供的说明：

合并来自多个节点的plugin-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

在这里：

跨多个应用程序服务器配置文件配置简单负载平衡 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服务器的web服务器设置以指向这个新文件，并更新了插件以使用新的合并文件。服务器启动，但我只获得请求转到第一个WebSphere服务器。我很清楚我为＆lt; VirtualHostGroup＆gt;做了什么元素不正确，并且是这个问题的背后。我认为我需要把所有的＆lt; VirtualHost＆gt;元素合并为一个组合＆lt; VirtualHostGroup＆gt;元素，还把所有的＆lt; Server＆gt;元素合并为一个＆lt; ServerCluster＆gt;元素，但我只是在猜测。

Answer 1

您的文件存在一些问题。

首先，您需要为这两台服务器设置cloneId，如configure a unique HTTP session clone ID 所述：

使用管理配置唯一的HTTP会话克隆ID   控制台，完成以下步骤：


点击Servers > Server Types > WebSphere application servers > server_name。

在Container Settings下，点击Web Container Settings > Web container。

在Additional Properties下，点击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   唯一值的长度必须为8 - 9个字母数字字符。例如，test1234是有效的cloneID值。

点击Apply或OK。

单击Save将配置更改保存到主配置。

然后你实际上需要合并（不要复制两者），plugin-cfg.xml的特定部分（我只是发布合并后的部分而不是整个文件）。因此，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:\eStorefront\CTire\Test\plugin/config/webserver1/plugin-key.kdb"/>
        <Property Name="stashfile" Value="E:\eStorefront\CTire\Test\plugin/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:\eStorefront\CTire\Test\plugin/config/webserver1/plugin-key.kdb"/>
        <Property Name="stashfile" Value="E:\eStorefront\CTire\Test\plugin/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"/>

我希望你明白这个主意。你必须测试它。您可以删除您不想处理的这些Uris，例如monitorServerWEB。如果可以路由到给定服务器的简单方法是为其他服务器设置LoadBalanceWeight=0。我看到你已经在插件中启用了跟踪，所以它会为你提供更多关于插件试图匹配uri，vhost和服务器的详细信息。
