Linux服务自启动

: java service wrapper tomcat linux服务 自动启动
引用
前几天总结了使用JSVC来设置tomcat作为linux服务并且开机自动启动，但是如果要更专业一点来控制tomcat的启动，使用Java Service Wrapper应该不失为一个好的选择，下面来总结一下Java Service Wrapper在Linux中对于tomcat启动的设置：

1、安装JDK、Tomcat,此处略过。比如tomcat安装在/opt/tomcat目录中。

2、使用命令wget 下载Java Service Wrapper(目前版本wrapper-linux-x86-32-3.2.3，官网：http://wrapper.tanukisoftware.org), 用命令tar -zxvc wrapper-linux-x86-32-3.2.3.tar.gz 解压，得到目录wrapper-linux-x86-32-3.2.3，使用ln -s wrapper-linux-x86-32-3.2.3 wrapper 给目录wrapper-linux-x86-32-3.2.3 建一个名称为wrapper的快捷方式。

3、复制wrapper\src\bin\sh.script.in到/opt/tomcat/bin目录，重命名为tomcat
复制wrapper\src\conf\wrapper.conf.in到/opt/tomcat/conf目录，重命名为wrapper.conf
复制wrapper\src\lib\lib目录下的所有3个文件到/opt/tomcat/lib目录
复制wrapper\bin目录下的wrapper文件到/opt/tomcat/bin目录

4、修改/opt/testapp/bin/tomcat文件
APP_NAME="tomcat"
APP_LONG_NAME="Tomcat Application Server"
WRAPPER_CMD="./wrapper"
WRAPPER_CONF="../conf/wrapper.conf"
赋予执行权限
chmod 775 /opt/tomcat/bin/tomcat
chmod 775 /opt/tomcat/bin/tomcat

5、修改/opt/tomcat/conf/wrapper.conf文件，如：
#********************************************************************

#********************************************************************
# Java Application
# 设置环境变量
set.JAVA_HOME=/usr/java/jdk1.6.0_01
set.CATALINA_HOME=/opt/tomcat
set.CATALINA_BASE=/opt/tomcat
wrapper.java.command=/usr/java/jdk1.6.0_01/bin/java

# Java Main class. This class must implement the WrapperListener interface
# or guarantee that the WrapperManager class is initialized. Helper
# classes are provided to do this for you. See the Integration section
# of the documentation for details.
# 使用WrapperStartStopApp，这样可以通过命令带start/stop来启动/停止程序。
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperStartStopApp

# Java Classpath (include wrapper.jar) Add class path elements as
# needed starting from 1
# 设置执行tomcat的classpath文件
wrapper.java.classpath.1=%CATALINA_HOME%/lib/wrapper.jar
wrapper.java.classpath.2=%CATALINA_BASE%/bin/bootstrap.jar

# Java Library Path (location of Wrapper.DLL or libwrapper.so)
# 设置tomcat的lib路径
wrapper.java.library.path.1=%CATALINA_HOME%/lib/

# Java Additional Parameters

wrapper.java.additional.1=-Djava.endorsed.dirs=%CATALINA_HOME%/common/endorsed

wrapper.java.additional.3=-Dcatalina.home=%CATALINA_HOME%
wrapper.java.additional.4=-Djava.io.tmpdir=%CATALINA_BASE%/temp

# Initial Java Heap Size (in MB)
# 设置tomcat的JVM初始化堆的大小
wrapper.java.initmemory=128

# Maximum Java Heap Size (in MB)
# 设置tomcat的JVM堆的最大值
wrapper.java.maxmemory=512

# Application parameters. Add parameters as needed starting from 1
# 设置启动、停止和重启参数
wrapper.app.parameter.1=org.apache.catalina.startup.Bootstrap
wrapper.app.parameter.2=1
wrapper.app.parameter.3=start

wrapper.app.parameter.4=org.apache.catalina.startup.Bootstrap
wrapper.app.parameter.5=true
wrapper.app.parameter.6=1
wrapper.app.parameter.7=stop

wrapper.filter.trigger.1=java.lang.OutOfMemoryError
wrapper.filter.action.1=RESTART

#********************************************************************
# Wrapper Logging Properties
#********************************************************************
# Format of output for the console. (See docs for formats)
wrapper.console.format=PM

# Log Level for console output. (See docs for log levels)
wrapper.console.loglevel=INFO

# Log file to use for wrapper output logging.
# 设置log文件路径
wrapper.logfile=%CATALINA_BASE%/logs/wrapper.log

# Format of output for the log file. (See docs for formats)
wrapper.logfile.format=LPTM

# Log Level for log file output. (See docs for log levels)
wrapper.logfile.loglevel=INFO

# Maximum size that the log file will be allowed to grow to before
# the log is rolled. Size is specified in bytes. The default value
# of 0, disables log rolling. May abbreviate with the 'k' (kb) or
# 'm' (mb) suffix. For example: 10m = 10 megabytes.
# 设置log文件最大值
wrapper.logfile.maxsize=5

# Maximum number of rolled log files which will be allowed before old
# files are deleted. The default value of 0 implies no limit.
#设置log文件最多个数
wrapper.logfile.maxfiles=10

# Log Level for sys/event log output. (See docs for log levels)
wrapper.syslog.loglevel=NONE

#********************************************************************
# Wrapper Windows Properties
#********************************************************************
# Title to use when running as a console
# windows下tomcat控制台名称
wrapper.console.title=Tomcat6 Application Server

#********************************************************************

wrapper.ntservice.name=tomcat6

# Display name of the service

# Mode in which the service is installed. AUTO_START or DEMAND_START
# 设置允许Tomcat服务自动启动
wrapper.ntservice.starttype=AUTO_START

# Allow the service to interact with the desktop.
wrapper.ntservice.interactive=false

6、设置tomcat开机自动运行：
ln -s /opt/tomcat/bin/tomcat /etc/init.d/tomcat

7、测试,执行命令：service tomcat start|stop|restart|status

至此，使用Java Service Wrapper来设置Tomcat作为Linux的服务完成，从此过程看来，Java Service Wrapper对tomcat的控制程度比tomcat自带的JSVC深入多了。
目录结构：
/opt/tomcat/bin

                 | wrapper
/opt/tomcat/logs
                 | wrapper.log（程序运行时自动产生）
/opt/tomcat/conf
                 | wrapper.conf
