现有设置：一个standalone的app server

先使用Profile Management Tool创建一个dmgr。

把AppSrv01添加到Dmgr01里面：

cd D:IBMWebSphereAppServerprofilesAppSrv01bin

addNode.bat localhost 8879

===================================================================================

D:IBMWebSphereAppServerprofilesAppSrv01bin>addNode.bat localhost 8879

ADMU0116I: Tool information is being logged in file

D:IBMWebSphereAppServerprofilesAppSrv01logsaddNode.log

ADMU0128I: Starting tool with the AppSrv01 profile

CWPKI0308I: Adding signer alias "CN=HGHLTR8Y32CC.corp.capgemini." to local

keystore "ClientDefaultTrustStore" with the following SHA digest:

11:0E:D2:82:EF:5B:F4:A4:FF:99:E9:C2:92:41:FC:2A:CA:90:66:C7

CWPKI0309I: All signers from remote keystore already exist in local keystore.

ADMU0001I: Begin federation of node HGHLTR8Y32CCNode01 with Deployment Manager

at localhost:8879.

ADMU0009I: Successfully connected to Deployment Manager Server: localhost:8879

ADMU0505I: Servers found in configuration:

ADMU0506I: Server name: server1

ADMU2010I: Stopping all server processes for node HGHLTR8Y32CCNode01

ADMU0510I: Server server1 is now STOPPED

ADMU0024I: Deleting the old backup directory.

ADMU0015I: Backing up the original cell repository.

ADMU0012I: Creating Node Agent configuration for node: HGHLTR8Y32CCNode01

ADMU0014I: Adding node HGHLTR8Y32CCNode01 configuration to cell:

HGHLTR8Y32CCCell01

ADMU0016I: Synchronizing configuration between node and cell.

ADMU0018I: Launching Node Agent process for node: HGHLTR8Y32CCNode01

ADMU0020I: Reading configuration for Node Agent process: nodeagent

ADMU0022I: Node Agent launched. Waiting for initialization status.

ADMU0030I: Node Agent initialization completed successfully. Process id is:

10976

ADMU0505I: Servers found in configuration:

ADMU0506I: Server name: nodeagent

ADMU0506I: Server name: server1

ADMU0300I: The node HGHLTR8Y32CCNode01 was successfully added to the

HGHLTR8Y32CCCell01 cell.

ADMU0306I: Note:

ADMU0302I: Any cell-level documents from the standalone HGHLTR8Y32CCCell01

configuration have not been migrated to the new cell.

ADMU0307I: You might want to:

ADMU0303I: Update the configuration on the HGHLTR8Y32CCCell01 Deployment

Manager with values from the old cell-level documents.

ADMU0306I: Note:

ADMU0304I: Because -includeapps was not specified, applications installed on

the standalone node were not installed on the new cell.

ADMU0307I: You might want to:

ADMU0305I: Install applications onto the HGHLTR8Y32CCCell01 cell using wsadmin

$AdminApp or the Administrative Console.

ADMU0003I: Node HGHLTR8Y32CCNode01 has been successfully federated.

D:IBMWebSphereAppServerprofilesAppSrv01bin>

===================================================================================

再去看原来那个standalone的app server的admin console已经打不开了，只有dmgr的admin console可以用了。

admin console里的Nodes页面多了一个Node: HGHLTR8Y32CCNode01

先把整个环境重启一下。

在admin console的WebSphere application server clusters页面添加两个server到cluster1中：

======================================================================================

Summary of actions:

Options	Values
Cluster Name	cluster1
Core Group	DefaultCoreGroup
Node group	DefaultNodeGroup
Prefer local	true
Configure HTTP session memory-to-memory replication	false

Server name	c1_svr1
Node	HGHLTR8Y32CCNode01(ND 8.0.0.0)
Weight	2
Clone Template	default
Clone Basis	Create the member using an application server template.
Select how the server resources are promoted in the cluster.	cluster
Generate unique HTTP ports	true

Server name	c1_svr2
Node	HGHLTR8Y32CCNode01(ND 8.0.0.0)
Weight	2
Clone Template	Version 8 member template
Generate unique HTTP ports	true

======================================================================================

然后把启动cluster1。

把样例程序DefaultApplication.ear部署到集群里面。

启动应用。

这样就可以分别访问cluster1里面两个成员的snoop程序了

http://localhost:9082/snoop

http://localhost:9083/snoop

当然了，这并不是我们想要的集群。

那就先安装一下IHS(IBM Http Server)和web server plugin，以及WebSphere Customization Toolbox

使用WebSphere Customization Toolbox生成一个webserver1的定义。

这个过程会自动在IHS的D:IBMHTTPServerconfhttpd.conf文件中增加下面两行：

======================================================================================

LoadModule was_ap22_module "D:IBMWebSpherePluginsbinmod_was_ap22_http.dll"
WebSpherePluginConfig "D:IBMWebSpherePluginsconfigwebserver1plugin-cfg.xml"

======================================================================================

生成的web server的plugin的配置文件位于：

D:IBMWebSpherePluginsconfigwebserver1

这个过程还会生成一个脚本configurewebserver1.bat，位于D:IBMWebSpherePluginsbin

将这个脚本拷贝至D:IBMWebSphereAppServerbin，并运行：

cd D:IBMWebSphereAppServerbin

D:IBMWebSphereAppServerbin>configurewebserver1.bat

======================================================================================

D:IBMWebSphereAppServerbin>configurewebserver1.bat

======================================================================================

这个过程将在dmgr里生成一个webserver1的定义。

当你会到admin console的Web servers页面，会发现多了一个webserver1。尝试从console里启动它，成功了！

而且你会发现DefaultApplication.ear也被自动map到webserver1了。

在IE里尝试访问snoop：

http://localhost/snoop

会发现你的request被load balance到cluster1中的两个app server了。

注意观察以下两项：

Local port

9082

com.ibm.websphere.servlet.application.host

c1_svr1
