Linux Server Deployment jar packages and the writing of shell scripts

Background: Documenting the process of deploying a JAR program in a Linux environment

1 Deployment Process record 1.1 program structure

The main function here is in the Demrest2.java file.

For ease of deployment, do the following two points:

1 A dependent jar file is not included in the exported jar package

2 The configuration file used by the program allows the user to customize it without placing it in the jar package.

1.2 Exporting a JAR package

You can export the normal jar package here. To facilitate the transfer, only the necessary program files are exported.

After the jar package is exported, go to the exported jar package and delete the profile tws.properties file.

1.3 Program Deployment

Place all the required jar packages under the Lib directory, including the jar package for our export project Tws-client-demo.jar

In the user-defined directory, place the run script and configuration file.

PS: The directory where you run the script is the root directory where the program runs, and all the configuration files and running scripts are placed in the same directory.

Here in the program how to read the configuration file, but also need to study well ....

#!/bin/shsourcemsgpath=/home/tws/server/tws-test/usermsg/lxw//etc/profilefor i in $HOME /server/tws-test/lib/*;    Do CLASSPATH= $i:"$CLASSPATH"; doneexport CLASSPATH=.: ${classpath}java  demo.rest.DemRest2 $sourceMsgPath $1 "success!"  

Explain the above script:

To run the program:

Under the user directory, the program can read the configuration file outside the jar package.

2 Standard Scripts

An example of a script found on the Internet:

When writing a shell script error, it can be used as a reference:

/bin/shexport java_home=/usr/java/jdk1. 6 . 0_18export CLASSPATH=.:${java_home}/lib/dt.jar:${java_home}/lib/tools.jarfor i in Lib/*. Jar ;         Do CLASSPATH=$i: ${classpath} doneexport CLASSPATH=-CP ${classpath} The package name where the main method resides. The name of the class where the Main method resides

If the above script does not execute successfully, you can try

#!/bin//etc/profilesource ~/.bash_profile

Under test:

JAVA-CP Java's CP command JAVA-CP.; C:\dir1\lib.jar TEST-CP and-classpath, is the path of the specified class to run dependent on other classes, usually class libraries, jar packages, such as the full path to the jar package, window semicolon ";" Delimited, Linux is a semicolon ":" Delimited. Wildcard characters are not supported and all jar packages need to be listed with a little "." Represents the current path.
