linux 下运行 java jar 的 shell  脚本

#!/bin/sh

basepath=$(cd `dirname $0`; pwd)
cd $basepath
cd ../

PWD=`pwd`
echo $PWD

for i in lib/*;
    do CLASSPATH=$CLASSPATH:$PWD/$i
done

export CLASSPATH=$CLASSPATH:$PWD/prespider.jar

java -Dfile.encoding=UTF-8 -verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -Xloggc:/tmp/javagc.log -XX:+HeapDumpOnOutOfMemoryError $@

#!/bin/sh
export JAVA_HOME=/usr/java/jdk1.6.0_38
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

echo "start"

basepath=$(cd `dirname $0`; pwd)
cd $basepath
cd ../

PWD=`pwd`
for i in lib/*;
    do CLASSPATH=$CLASSPATH:$PWD/$i
done

export CLASSPATH=$CLASSPATH:$PWD/maprHbase.jar

className='com.ysq.mrhb.example.SubmitHbmrJob'
parameter=("/home/output/hbase/" "/home/output/hbase")


echo ${parameter[*]}

java -Dfile.encoding=UTF-8 -Xmx1024M $className ${parameter[*]} > $PWD/runtimeLogs/xtreamTest.log 2>&1

运行之前判断是否正在执行

#!/bin/sh

nowPath=$(cd `dirname $0`; pwd)
cd $nowPath
cd ../

basePath=`pwd`

className='com.ysq.test.TestRun'
parameter=$@

function javaRun(){
    echo "start"

    for i in lib/*; do
        CLASSPATH=$CLASSPATH:$basePath/$i
    done

    #base jar
    for i in target/*; do
        CLASSPATH=$CLASSPATH:$basePath/$i
    done

    cd ./target/
   
    java -Dfile.encoding=UTF-8 -Xmx256M $className ${parameter[*]} > $basePath/runtimeLogs/runOut.log 2>&1 &
}


count=`ps -ef | grep $className | grep -v "grep" | wc -l`

if [ $count -gt 0 ];then
    currentThread=`ps -ef | grep $className | grep -v "grep"`
    echo "$className has been started, please stop it first : "
    echo " $currentThread"

else
    #run java
    javaRun
