Packaged Java applications as services under Linux __linux

packaging Java applications into services under Linux1

This article describes how to use the Java Wrapper service in the following steps: (Tested through CentOS5.1 Linux)

1. From http://wrapper.tanukisoftware.org/doc/english/download.jsp

Download Wrapper-linux-x86-32-3.3.1.tar (please use the Community version, because professional and standard version need to purchase licenses);

2. Decompression Wrapper-linux-x86-32-3.3.1.tar for wrapper-linux-x86-32-3.3.1;

3. Prepare the directory for the Program (APP), including Bin,conf,lib,logs:

4. Copy wrapper-linux-x86-32-3.3.1\bin\wrapper (for binary file) to bin\;

5. Copy wrapper-linux-x86-32-3.3.1\src\bin\sh.script.in to bin\ and renamed app to copy the configuration files used by the app to the directory, including. Ini,.xml;

6. Copy wrapper-linux-x86-32-3.3.1\src\conf\wrapper.conf.in to conf\, and renamed to Wrapper.conf;

7. Copy wrapper-linux-x86-32-3.3.1\lib\wrapper.jar,libwrapper.so to lib\ and copy the jar package used by app to the directory;

8. Edit the app, set the name of the application (use NotePad2 or EditPlus when you edit)

# application
App_name= "MailSender"
App_long_name= "MailSender Application"

9. Editor Wrapper.conf

# Java Main class. This class must implement the Wrapperlistener interface
# or guarantee that's Wrappermanager class is initialized. Helper
# classes are provided to doing this for you. The integration section
# of the documentation for details.
Wrapper.java.mainclass=org.tanukisoftware.wrapper.wrappersimpleapp #默认使用

# Java Classpath (include Wrapper.jar) Add class path elements as
# needed starting from 1

Wrapper.java.classpath.1=.. /lib/wrapper.jar
Wrapper.java.classpath.2=.. /lib/classes12.jar #其它引入jar
Wrapper.java.classpath.3=.. /lib/activation.jar #其它引入jar
Wrapper.java.classpath.4=.. /lib/mail.jar #其它引入jar
Wrapper.java.classpath.5=.. /lib/app.jar #当前应用jar

# Java Library Path (location of Wrapper.DLL or libwrapper.so)
Wrapper.java.library.path.1=.. /lib #Windows version uses the Wrapper.dll,linux version libwrapper.so

# application parameters. ADD parameters as needed starting from 1

10. Use SSH to upload the app directory to the Linux server/usr/local/app;

11. Login SSH, execute:

#chmod 755/usr/local/app

#cd/usr/local/app/bin

#sudo chmod 755 App

#sudo chmod 755 Wrapper

Complete deployment;

The last command resolves: unable to locate any of the following binaries:
/app/bin/./wrapper-linux-x86-32
/app/bin/./wrapper-linux-x86-64
/app/./wrapper (Found but not executable.) problem;

12. Execute command:/usr/local/app/bin/app Console|start|stop|restart can start the service.

If you want to check that the service is performing properly, you can use the console parameter first, and start the service if you are normal.

Usage:/usr/local/tserverproxy/bin/app [Console | start | stop | restart | condrestart | status | install | remove | dump ]


Commands:
Console Launch in the current console.
Start start in the background as a daemon process.
Stop stop if running as a daemon or in another console.
