Weblogic集群配置关键点

1.  理解Weblogic集群模型及概念

2.  JDK选择，12c选择Sun JDK，其它版本选择JRockit JDK

3  JDK以root用户安装

4.  Weblogic产品以非root用户安装

5.  Weblogic集群以root用户配置

6.  Weblogic提供config和wlst两个工具配置集群，推荐用wlst

7. wlst提供交互、脚本、嵌入三种方式使用，学习推荐用交互，生产环境配置推荐用脚本方式

8. wlst中startNodeManager()函数是异步的，它的结束并不意味着nodemanager已启动

9. 域创建完毕后，如果nodemanager是启动状态，需重启nodemanager加载新的域配置

10. 配置完次节点后，需向主节点的AdminServer注册该节点

下面一个主节点配置脚本样例：

print('***************** init ip and host of all nodes *********************')
MAIN_NODE_IP='10.6.143.55'
MAIN_NODE_HOST='55_weblogic_mdm_cn'
MINOR_NODE_IP='10.6.143.56'
MINOR_NODE_HOST='56_weblogic_mdm_cn'

print('**************** init domain config infomations *********************')
