Wrapper配置详解及高级应用

  1.文件编码及子配置文件 
        文件头部包含了配置文件编码格式，子配置文件等相关信息，如下所示：

#文件编码，每个配置文件起始位置必须指定该文件的编码格式
encoding=UTF-8

# 如果包含配置文件出现问题可以使用debug调试模式，去掉一个"#"，格式为#include.debug
#include.debug

# 包含子配置文件，可以是配置信息也可以是许可信息
include ../conf/wrapper-license.conf
include ../conf/wrapper2.conf

# 是否开启许可文件debug模式
wrapper.license.debug=TRUE

  通过子配置文件的配置可以使主配置文件关联最多10级子配置，例如：wrapper.conf 包含 wrapper2.conf ，wrapper2.conf 包含wrapper3.conf ..... wrapper9.conf 包含wrapper10.conf，文件结构如下：

wrapper.conf
|-wrapper2.conf
|-wrapper3.conf
      .....
|-wrapper9.conf
|-wrapper10.conf

    2.Wrapper 语言设置

        通过这两项的设置可以指定Wrapper 的语言种类，可以在Wrapper 官网下到这些语言包支持，目前不支持中文。

# 指定Wrapper语言，默认使用系统语言
wrapper.lang=en_US

#指定Wrapper 语言资源位置，如果该文件不存在则默认设置为en_US
wrapper.lang.folder=../lang

 

 

        3.Wrapper Java 相关属性配置

        (1)java运行环境设置

# Java 程序配置：
#   (1)默认使用PATH环境变量配置信息则使用下列配置形式
wrapper.java.command=java

#   (2)如果想单独配置运行程序，则可采用此种配置方式
set.JAVA_HOME=/java/path
wrapper.java.command=%JAVA_HOME%/bin/java

# java程序日志级别
wrapper.java.command.loglevel=INFO

 

        (2)程序入口

# Java Main class，也就是程序入口  
#该类需要实现WrapperListener 接口并保证WrapperManager 得到初始化(调用WrapperManager.start(WrapperListener listener, String[] args) 方法)。
wrapper.java.mainclass=com.helloworld.hello.HelloWorld

 

        (3)类库设置

# Java Classpath配置，必须从序号"1"开始，添加新的jar包后序号递增
wrapper.java.classpath.1=../lib/wrapper.jar
wrapper.java.classpath.2=../lib/hello.jar

# Java 类库路径 (Wrapper.DLL 或 libwrapper.so 依赖文件的存放位置)
wrapper.java.library.path.1=../lib

 

        (4)JVM相关配置

# 32/64位选择，true为自动选择
wrapper.java.additional.auto_bits=TRUE

# Java附加参数
wrapper.java.additional.1=

 

        附加参数即为java命令可选参数，如下所示： 

-d32          use a 32-bit data model if available

-d64          use a 64-bit data model if available
-server	  to select the "server" VM
  The default VM is server.
  
-cp <class search path of directories and zip/jar files>
-classpath <class search path of directories and zip/jar files>
  A : separated list of directories, JAR archives,
  and ZIP archives to search for class files.
-D<name>=<value>
  set a system property
-verbose[:class|gc|jni]
  enable verbose output
-version      print product version and exit
-version:<value>
  require the specified version to run
-showversion  print product version and continue
-jre-restrict-search | -jre-no-restrict-search
  include/exclude user private JREs in the version search
-? -help      print this help message
-X            print help on non-standard options
-ea[:<packagename>...|:<classname>]
-enableassertions[:<packagename>...|:<classname>]
  enable assertions
-da[:<packagename>...|:<classname>]
-disableassertions[:<packagename>...|:<classname>]
  disable assertions
-esa | -enablesystemassertions
  enable system assertions
-dsa | -disablesystemassertions
  disable system assertions
-agentlib:<libname>[=<options>]
  load native agent library <libname>, e.g. -agentlib:hprof
    see also, -agentlib:jdwp=help and -agentlib:hprof=help
-agentpath:<pathname>[=<options>]
  load native agent library by full pathname
-javaagent:<jarpath>[=<options>]
  load Java programming language agent, see java.lang.instrument
-splash:<imagepath>
  show splash screen with specified image

 

        内存大小设置：

# Java Heap 初始化大小(单位：MB)
wrapper.java.initmemory=3

# Java Heap 最大值(单位：MB)
wrapper.java.maxmemory=64

 

        应用程序参数设置：

# 应用程序参数，也就是main函数的String[] args参数值，序号需从"1"开始，例如：
wrapper.app.parameter.1=g21121
wrapper.app.parameter.2=http://286.iteye.com/

  

        在main函数和start方法中添加了参数打印语句来观察参数是否已经传入，代码如下：

package com.helloworld.hello;

import org.tanukisoftware.wrapper.WrapperListener;
import org.tanukisoftware.wrapper.WrapperManager;

public class HelloWorld implements WrapperListener {

    public static void main(String[] args) {
        // 打印参数
        for (String arg : args)
            System.out.println(arg);
        WrapperManager.start(new HelloWorld(), args);
    }

    @Override
    public void controlEvent(int event) {
        System.out.println("controlEvent(" + event + ")");
        if ((event == WrapperManager.WRAPPER_CTRL_LOGOFF_EVENT) && (WrapperManager.isLaunchedAsService() || WrapperManager.isIgnoreUserLogoffs())) {
        } else {
            WrapperManager.stop(0);
        }
    }

    @Override
    public Integer start(String[] args) {
        // 打印参数
        for (String arg : args)
            System.out.println(arg);
        System.out.println("hello world!");
        return null;
    }

    @Override
    public int stop(int exitCode) {
        System.out.println("stop(" + exitCode + ")");
        return exitCode;
    }

}

 

        重新运行服务，结果如下：

root@TFS:/usr/local/wrapper/bin# ./hello console
Running helloWorld...
wrapper  | --> Wrapper Started as Console
wrapper  | Java Service Wrapper Community Edition 64-bit 3.5.20

jvm 1    | http://286.iteye.com/
jvm 1    | hello world!

wrapper  | <-- Wrapper Stopped

 

 

        4.Wrapper 日志配置

# 是否显示debug日志
wrapper.debug=TRUE

# 控制台信息输出格式
wrapper.console.format=PM

# 控制台日志级别
wrapper.console.loglevel=INFO

# 日志文件位置及名称
wrapper.logfile=../logs/wrapper.log

# 日志文件输出格式
wrapper.logfile.format=LPTM

# 日志文件日志级别
wrapper.logfile.loglevel=INFO

# 限制日志文件大小，0为不限制，参数：k,m,g等
wrapper.logfile.maxsize=10m

# 限制最大日志文件数，0为不限制
wrapper.logfile.maxfiles=0

# syslog 日志级别
wrapper.syslog.loglevel=NONE

 

 

        5.Wrapper 基本属性配置

# 允许使用非连续编号的属性，例如：path的序号可以打乱
wrapper.ignore_sequence_gaps=TRUE

# 如果pid文件已经存在则不启动程序
wrapper.pidfile.strict=TRUE

# 控制台启动时显示的标题
wrapper.console.title=------------Wrapper Console------------

 

 

        6.Wrapper JVM 检查

# 检测JVM中的死锁线程（需要标准版Wrapper）
wrapper.check.deadlock=TRUE
#间隔，单位：秒
wrapper.check.deadlock.interval=10
#出现死锁时处理事件
wrapper.check.deadlock.action=RESTART
#信息输出级别，FULL:全部;SIMPLE:精简;NONE:无;
wrapper.check.deadlock.output=FULL

 

        以下为wrapper.check.deadlock.action的事件类型： 

DEBUG :
    will cause a debug message to be logged. This is only really useful in helping to understand when the action is fired.
DUMP :
    will invoke a thread dump.
GC (Since ver. 3.5.7) :
    will invoke a full garbage collection sweep in the JVM. Be aware that doing this frequently can affect performance of the JVM as a full sweep will often cause all threads to freeze for the duration of the GC.
RESTART :
    will stop the current JVM and then restart a new invocation.
SHUTDOWN :
    will stop the JVM as well as the Wrapper.
USER_<n> (Professional Edition) :
    will cause a user defined event to be fired. This can be either the sending of an email, or the execution of an external system command. The command could be anything from performing clean up operations to raising an SNMP trap.
PAUSE :
    will pause the Java application if pausing is enabled and the JVM is running. See the wrapper.pausable property for details.
RESUME :
    will resume the Java application if it is in a paused state. This could be used if the JVM is not stopped when paused. See the wrapper.pausable property for details.
SUCCESS (Since ver. 3.5.5) :
    will tell the Wrapper to reset its internal failed invocation count and count the current JVM invocation as "successful". This is probably not useful in this context, but here for consistency with other properties.
NONE :

 

 

        7.内存溢出检测

# 内存溢出检测，Wrapper提供了几种不同的匹配机制
wrapper.filter.trigger.999=wrapper.filter.trigger.*java.lang.OutOfMemoryError
wrapper.filter.allow_wildcards.999=TRUE
wrapper.filter.action.999=NONE
wrapper.filter.trigger.1000=[Loaded java.lang.OutOfMemoryError
wrapper.filter.action.1000=NONE
wrapper.filter.trigger.1001=java.lang.OutOfMemoryError
#wrapper.filter.trigger.1001=Exception in thread "*" java.lang.OutOfMemoryError
#wrapper.filter.allow_wildcards.1001=TRUE
wrapper.filter.action.1001=RESTART
wrapper.filter.message.1001=The JVM has run out of memory.

 

 

        8.Wrapper Email 通知设置(需要专业版Wrapper)

# 邮件基本信息设置
wrapper.event.default.email.debug=TRUE
#smtp服务器地址
wrapper.event.default.email.smtp.host=
#smtp服务器端口
wrapper.event.default.email.smtp.port=25
#邮件主题
wrapper.event.default.email.subject=[%WRAPPER_HOSTNAME%:%WRAPPER_NAME%:%WRAPPER_EVENT_NAME%] Event Notification
#发件人地址
wrapper.event.default.email.sender=<Sender email>
#收件人地址
wrapper.event.default.email.recipient=<Recipient email>
# 指定文件内容
wrapper.event.jvm_restart.email.body=The JVM was restarted.\n\nPlease check on its status.\n

 

# 邮件日志相关配置
wrapper.event.default.email.attach_log=TRUE
wrapper.event.default.email.maillog.lines=50
wrapper.event.default.email.maillog.format=LPTM
wrapper.event.default.email.maillog.loglevel=INFO

 

# 触发事件，即当以下事件为true时发送邮件
wrapper.event.wrapper_start.email=TRUE
wrapper.event.jvm_prelaunch.email=TRUE
wrapper.event.jvm_start.email=TRUE
wrapper.event.jvm_started.email=TRUE
wrapper.event.jvm_deadlock.email=TRUE
wrapper.event.jvm_stop.email=TRUE
wrapper.event.jvm_stopped.email=TRUE
wrapper.event.jvm_restart.email=TRUE
wrapper.event.jvm_failed_invocation.email=TRUE
wrapper.event.jvm_max_failed_invocations.email=TRUE
wrapper.event.jvm_kill.email=TRUE
wrapper.event.jvm_killed.email=TRUE
wrapper.event.jvm_unexpected_exit.email=TRUE
wrapper.event.wrapper_stop.email=TRUE
