weblogic 脚本创建Managed Server (受管服务器)

## 说明 ##

`weblogic`安装目录下有一个创建`Managed Server`的脚本，脚本位于`/u01/app/Oracle/Middleware/oracle_common/common/bin/config.sh`下，但脚本会启动一个GUI界面程序，在Linux下需要安装图形界面程序，非常不方便。`wlst(WebLogic Scripting Tools,WebLogic)`是一个用来管理和配置weblogic的CLI命令行工具，可以运行`Jython`脚本，本文介绍如何通过该工具创建Managed Server。

## WLST介绍 ##

wlst位于`/u01/app/Oracle/Middleware/wlserver_10.3/common/bin/wlst.sh`目录下，其中`/u01/app/Oracle/Middleware/wlserver_10.3`目录为`$WEBLOGIC_HOME`，所以严谨的讲，是安装在`$WEBLOGIC_HOME/common/bin/wlst.sh`下。直接执行该脚本即可运行wlst工具。

$ cd /u01/app/Oracle/Middleware/wlserver_10.3/common/bin/
    $ ./wlst.sh
    
    Initializing WebLogic Scripting Tool (WLST) ...
    
    Welcome to WebLogic Server Administration Scripting Shell
    
    Type help() for help on available commands
    
    wls:/offline> connect('weblogic','weblogic1','t3://localhost:7001')
    Connecting to t3://localhost:7001 with userid weblogic ...
    Successfully connected to Admin Server 'AdminServer' that belongs to domain 'base_domain'.
    
    Warning: An insecure protocol was used to connect to the
    server. To ensure on-the-wire security, the SSL port or
    Admin port should be used instead.
    
    wls:/base_domain/serverConfig> cd('/')
    wls:/base_domain/serverConfig> ls()
    dr--   AdminConsole
    dr--   AppDeployments
    dr--   BridgeDestinations
    dr--   Clusters
    dr--   CoherenceClusterSystemResources
    dr--   CoherenceServers
    ....

wlst有`offline(离线)`和`online(在线)`两种模式，通过`connect`命令可以从offline进入online，wlst按照Linux目录形式对weblogic资源进行管理，甚至连操作的命令都和Linux高度相似，比如`cd`是切换到指定资源路径下，`ls()`是列出该目录下所有资源。如要了解更多关于wlst的内容，可以查看[官方文档][Link 1]。

## wlst脚本 ##

本脚本原作者为[Tim Hall][]，本文这里稍作修改，以下为脚本代码

***create\_managed\_server.py***

#!/usr/bin/python
    # Author : Tim Hall
    # Modified : Jianfeng.Zheng
    # Save Script as : create_managed_server.py
    
    import time
    import getopt
    import sys
    import re
    
    # Get location of the properties file.
    properties = ''
    try:
       opts, args = getopt.getopt(sys.argv[1:],"p:h::",["properies="])
    except getopt.GetoptError:
       print 'create_managed_server.py -p <path-to-properties-file>'
       sys.exit(2)
    for opt, arg in opts:
       if opt == '-h':
          print 'create_managed_server.py -p <path-to-properties-file>'
          sys.exit()
       elif opt in ("-p", "--properties"):
          properties = arg
    print 'properties=', properties
    
    # Load the properties from the properties file.
    from java.io import FileInputStream
     
    propInputStream = FileInputStream(properties)
    configProps = Properties()
    configProps.load(propInputStream)
    
    # Set all variables from values in properties file.
    adminUsername=configProps.get("admin.username")
    adminPassword=configProps.get("admin.password")
    adminURL=configProps.get("admin.url")
    msName=configProps.get("ms.name")
    msAddress=configProps.get("ms.address")
    msPort=configProps.get("ms.port")
    msMachine=configProps.get("ms.machine")
    
    # Display the variable values.
    print 'adminUsername=', adminUsername
    print 'adminPassword=', adminPassword
    print 'adminURL=', adminURL
    print 'msName=', msName
    print 'msAddress=', msAddress
    print 'msPort=', msPort
    print 'msMachine=', msMachine
    
    # Connect to the AdminServer.
    connect(adminUsername, adminPassword, adminURL)
    
    edit()
    startEdit()
    
    # Create the managed Server.
    cd('/')
    cmo.createServer(msName)
    cd('/Servers/' + msName)
    cmo.setListenAddress(msAddress)
    cmo.setListenPort(int(msPort))
    
    
    # Associated with a node manager.
    cd('/Servers/' + msName)
    cmo.setMachine(getMBean('/Machines/' + msMachine))
    
    save()
    activate()
    
    disconnect()
    exit()

## properties文件 ##

脚本所需参数通过properties文件传入，以下是properties文件

***api-api-managed-server.properties***

# AdminServer connection details.
    admin.username=weblogic
    admin.password=weblogic1
    admin.url=t3://10.1.11.71:7001
    
    ms.name=api-server
    ms.address=0.0.0.0
    ms.port=7002
    ms.machine=api-server-machine

`admin.username`: weblogic管理员用户名  
`admin.password`: weblogic管理员密码  
`admiin.url`: weblogic控制台地址需要加上t3协议字段  
`ms.name`: managed server名称，可以自定义  
`ms.address`: managed server监听地址  
`ms.port`: managed server监听端口号  
`ms.machine`: managed server关联的计算机名称

`ms.machine`需要提前创建好，可以在weblogic控制台页面[http://localhost:7001/console/console.portal?\_nfpb=true&\_pageLabel=CoreMachineMachineTablePage][http_localhost_7001_console_console.portal_nfpb_true_pageLabel_CoreMachineMachineTablePage]创建

## 运行 ##

将`create_managed_server.py`和`api-api-managed-server.properties`文件上传到服务器，这里上传到目录`~/shell`下

$ cd /u01/app/Oracle/Middleware/user_projects/domains/base_domain/bin
    $ . ./setDomainEnv.sh
    $ java weblogic.WLST ～/shell/create_managed_server.py -p ～/shell/api-managed-server.properties

***ps：. ./setDomainEnv.sh第一个点(.)不能省略***

执行完毕后登录console查看结果。
