周五,BEA,推荐,NM,以操作系统服务来运行,配置基于,Java,的节点管理器包含,在,Windows,中重新配置,NM,启动服务,在多个机器上配置节点管理器,查看,nodemanager.properties,在,Windows,中重新配置,NM,服务,使用,uninstallNodeMgrSvc.cmd,删除服务,编辑,installNodeMgrSvc.cmd,来指定监听地址与端口,运行,installNodeMgrSvc.cmd,重新重启安装,NM,服务,2025/12/5 周五,在多个机器中配置,NM,节点管理器应该在每个机器上安装配置,可以使用,WLST,脚本命令,nmEnroll,，可以把一个机器中的,Domain,中所有的信息复制到另一台机器中,nmEnroll(domainDir,nmHome),这个命令会从管理服务器中下载下面文件,nm_password.properties,，包含加密的用户名密码,SerializedSystemIni.dat,文件,2025/12/5 周五,查看,nodemanager.properties,在,nodemanager.properties,文件中指定了基于,Java,的,NM,属性,在命令行中的值要优先于,nodemanager.properties,中的值,在,nodemanager.properties,文件中配置启动脚本,设置,the,StartScriptEnabled,属性为,True,设置,StartScriptName,属性指向你的脚本名字,2025/12/5 周五,其它配置选项,其它,NM,配置任务包括,给机器配置节点管理器,配置,nodemanager.domains,文件,配置远程启动参数,确保定义了管理,Server,的地址,设置,NM,环境变量,2025/12/5 周五,给机器配置,NM,MachinesConfigurationNode,2025/12/5 周五,配置,nodemanager.domain,文件,nodemanager.domains,文件指定了,NM,可以控制的,Domain,当用户发出一个命令,NM,从这个文件中查找,Domain,目录,2025/12/5 周五,配置远端启动参数,2025/12/5 周五,确保定义管理服务地址,2025/12/5 周五,设置,NM,环境变量,2025/12/5 周五,Environment Variable,Description,JAVA_HOME,Root directory of JDK that you are using for Node Manager.For example:,set JAVA_HOME=c:beajdk1.5.0_06,Node Manager has the same JDK version requirements as WebLogic Server.,WL_HOME,WebLogic Server installation directory.For example:,set WL_HOME=c:bea,wlserver_10.0,PATH,Must include the WebLogic Server bin directory and path to your Java executable.For example:,set PATH=%WL_HOME%serverbin;%JAVA_HOME%bin;%PATH%,LD_LIBRARY_PATH(UNIX only),For HP UX and Solaris systems,you must include the path to the native Node Manager libraries.,Solaris example:,LD_LIBRARY_PATH:$WL_HOME/server/native/solaris:$WL_HOME/server/lib/solaris/oci816_8,HP UX example:,SHLIB_PATH=$SHLIB_PATH:$WL_HOME/server/native/hpux11:$WL_HOME/server/lib/hpux11/oci816_8,CLASSPATH,You can set the Node Manager CLASSPATH either as an option on the java command line used to start Node Manager,or as an environment variable.,Windows example:,set CLASSPATH=.;%WL_HOME%serverlibweblogic_sp.jar;%WL_HOME%serverlibweblogic.jar,节点管理器配置及日志文件,2025/12/5 周五,节点管理器配置及日志文件,NM,配置文件包含,:,nodemanager.properties,nodemanager.hosts,nodemanager.domains,nm_data.properties,nm_password.properties,boot.properties,startup.properties,server_name.lck,server_name.pid,server_name.state,NM,日志文件包含,:,nodemanager.log,server_name.out,2025/12/5 周五,大纲,日志和监听,使用日志文件,监听,Server,2025/12/5 周五,使用日志文件,使用日志文件可以帮助我们发现,经常访问的资源,数据的发送与接收情况,用户访问时的,IP,地址,在访问时出现的异常信息,性能信息,2025/12/5
