websphere 受管节点问题

描述：在192.168.200.201下安装websphere management节点和一个受管节点Custom01,在192.168.200.202上安装一个受管节点Custom02,启动192.168.200.201下management节点和受管节点Custom01，命令如下：./startManager.sh;./startNode.sh。然后试图启动192.168.200.202的受管节点Custom02,报如下错误：

到目录下找，的确文件不存在。
然后到网上查找原因，有人建议如下：

你的NODE是不是已经加入CELL，你有没有运行过ADDNODE.SH？

2.安装WAS补丁到6.1.0.29后重试

3.如果还不行，我建议你别为WAS管理上的问题折腾了，马上把DMGR, NODE的PROFILE统统删掉，为一个WAS管理的问题折腾一个星期不值得，立即用PMT.SH重建CELL和NODE。

于是运行./addNode.sh 192.168.200.201 8879,输入用户名、密码后，提示如下：

ADMU0001I: Begin federation of node newNode1 with Deployment Manager at
           DeploymentMgr:8879.
ADMU0009I: Successfully connected to Deployment Manager Server: DeploymentMgr:8879
ADMU0505I: Servers found in configuration:
ADMU0506I: Server name: newServer1
ADMU2010I: Stopping all server processes for node newNode1
ADMU0512I: Server newServer1 cannot be reached. It appears to be stopped.
ADMU0024I: Deleting the old backup directory.
ADMU0015I: Backing up the original cell repository.
ADMU0012I: Creating Node Agent configuration for node: newNode1

ADMU0027E: An error occurred during federation ADMU0036E: The Deployment
           Manager cannot lookup by name host newHost1 at address
           10.230.21.184; rolling back to original configuration.
ADMU0211I: Error details may be seen in the file:
           /…/profile/logs/addNode.log
ADMU0026I: An error occurred during federation; rolling back to original
           configuration.
ADMU0111E: Program exiting with error:

于是继续搜索，找到一个解决方法：

Solution:

make sure newHost1 and the host of deploymentManager can be reached each other

or check both /etc/hosts to make sure have both hostName。

 

 

 

于是在两天机器上都添加对方的ip和主机名，方法如下：

       vi /etc/hosts，录入

      

 

127.0.0.1 localhost.localdomain localhost

192.168.1.100 server1 server1

192.168.1.120 server2 server2

 

再次运行./addNode.sh 192.168.200.201 8879，执行成功。受管节点也跟着启动啦。一切0k.
