Java server shallow into the shallow out of the brief Java program release

This article will document the deployment settings for a simple Java program on Linux, as well as the writing of the release script.  Rough, brief. Magic! Don't move

1. First write a simple Java program, a dead loop, constantly output a word.

2. Share the project to SVN.

3. Write the publish_test.sh script, implement the SVN source checkout, call ant compile, package, and other preparation operations.

<span style= "FONT-SIZE:18PX;" . /home/testjava/publish/config.shmkdir-p ${publish_test_svn_root}if [' Ls-la ${publish_test_svn_root} | wc-l ' = = 3]then        svn checkout ${url_svn_test_root} ${publish_test_svn_root}else        svn update ${publish_test_svn_root}fiant- BuildFile ${publish_test_root}/build.xml cleanant-f ${publish_test_root}/build.xmlmkdir-p ${PUBLISH_TEST_LOGS_ROOT }touch ${publish_test_log}</span>

Some of the path information in config.sh is pre-declared.

4. Use ant to compile and package the project. Here you write the configuration file. I use the default name Build.xml.

<span style= "FONT-SIZE:18PX;" ><?xml version= "1.0" encoding= "UTF-8" standalone= "no"? ><project basedir= "." default= "Build" name= "test"        > <property environment= "env"/> <property name= "Root.path" value= "/home/testjava/publish"/> <property name= "Db.path" value= "${root.path}/testjava"/> <property name= "Db.svn.path" value= "${DB.PA Th}/svn "/> <property name=" Db.source.path "value=" ${db.svn.path}/src "/> <property name=" db.lib.p Ath "value=" ${db.svn.path}/libs "/> <property name=" Db.output.path "value=" ${db.path}/output "/> < Property Name= "Db.binout.path" value= "${db.output.path}/bin"/> <property name= "Db.jarout.path" value= "${db.ou Tput.path}/jar "/> <property name=" db.jar.name "value=" Testjava.jar "/> <property name=" DebugLevel "Value=" Source,lines,vars "/> <property name=" target "value=" 1.6 "/> <property name=" source "Value= "1.6"/> <path id= "Db.classpath" > <fileset file= "${db.lib.path}/*.jar" >  </fileset> </path> <target depends= "build-db,pack-db" name= "Build"/> <target Name= "Init" > <mkdir dir= "${db.binout.path}"/> <mkdir dir= "${db.jarout.path}"/&G        T </target> <target name= "clean" > <delete dir= "${db.binout.path}"/> & Lt;delete file= "${db.jarout.path}/${db.jar.name}"/> </target> <target depends= "Init" name= "build -db "> <javac debug=" true "Debuglevel=" ${debuglevel} "destdir=" ${db.binout.path} "source=" ${source} "t                arget= "${target}" Includeantruntime= "on" encoding= "UTF8" > <src path= "${db.source.path}"/> <classpath refid= "Db.classpath"/> </javac> </target> <target Name = "Pack-db" >                <jar destfile= "${db.jarout.path}/${db.jar.name}" basedir= "${db.binout.path}"/> </target&gt ;</project></span>

The clean here can be set to build dependencies, which I did not write. Javac compiles the source code into Class,jar to package the class into a jar package.

5. Write a script that runs the Jar package project as a server. start.sh

<span style= "FONT-SIZE:18PX;" >JAVA-DSERVER_NAME=/HOME/TESTJAVA/PUBLISH/TESTJAVA/OUTPUT-DJAVA.NET.PREFERIPV4STACK=TRUE-SERVER-XMX1G- xmn512m-cp/home/testjava/publish/testjava/output/jar/* test.system.main</span>

6. Establish a system service Testjava with the goal of running start.sh.

First write the service script testjava.sh under/ETC/INIT.D.

<span style= "FONT-SIZE:18PX;" >#!/bin/sh#chkconfig:35 80#description:testjava serverexec_path=/home/testjava/publish/testjava/outputexec= Start.shpid= "" If [-X $EXEC +path/%exec]; Thenecho "Project not found ..." Exit 1figetpid () {pid= ' ps AXJF | grep "Dserver_name=${exec_path}" | Grep-v "grep" | awk ' {print $} '}stop () {getpidif [-Z ${pid}]then echo "Error:server have not been started ..." Else echo "        Server is stoping ... "kill-15 ${pid}fi}start () {getpidif [-Z ${pid}]then echo" Server is starting ... " CD ${exec_path}./${exec} >>logs/log 2>&1 &else echo "Error:server has been started Al        Ready ... "Fi}restart () {Stop start}case" $ "in start) start;        stop) stop;;        restart) restart;;  status) status; *) echo "Usage:service $EXEC {start|stop|restart|status}" exit 1esacexit 0</span>

Where log redirection is 2>&1 the error message is transferred to normal output to standard & is to run this statement in the background.

Finally Chkconfig--add autoruntest Add the service.

7. Write the final start and stop scripts.

startall.sh

Service testjava.sh Start

stopall.sh

Service testjava.sh Stop

at this point, a simple release process is complete. Whenever a version update needs to be published, if the server is running, the stopall.sh is executed first. Then perform the publish_test.sh release. The last execution startall.sh starts. The run-time log is viewed in the pre-redirected Logs/log file.
