linux下運行java程序 和 優化的幾種方式

1..直接nohup後臺運行jar包

創建test.sh 文件內容如下

nohup java -jar ZL_LRC_RES.jar >/dev/null  &

注意步驟

1:導出可執行的jar包，設置好main方法
2：上傳的sh腳本注意編碼
vi test.sh
set fileformat=unix

3：./test.sh執行

4：ps -ef|grep java 查看進程

5：查看輸出

2..通過ant導出java程序執行

ant腳本導出jar包後傳到linux服務器

執行的sh腳本

#! /bin/ksh
. ${HOME}/.profile


# set 配置文件地址
cp="/scmgt/shell/gt/config"

# set ant導出的jar包
cp="$cp:/scmgt/shell/gt/productServer.jar"

#set 要用到的服務器上第三方公用jar包 ，如果jar包中有productServer.jar會覆蓋之前的，所以要grep -v 

basedir=/scmgt/productServer/jboss7/standalone/deployments/productServer.war/WEB-INF/
libdir=$basedir/lib
for file in `ls -1 $libdir/*.jar|grep -v "productServer.jar"`
do
cp="$cp:$file"
done
echo $cp
export CLASSPATH=$cp

#運行腳本${1} 是傳入參數 如：./test.sh  3
java -Ddefault.client.encoding="GBK" -Dfile.encoding="GBK" -Duser.language="Zh" -Duser.region="CN" -Duser.timezone=GMT+8 com.sitech.nbc.product.service.impl.ChTFtpMusicFileServiceImpl ${1}

3..通過crontab -e 運行java定時任務

1.crontab -e 進入定時文件,編輯

## add by gt 每隔5分鐘執行如下腳本
*/5 * * * * sh /scmgt/shell/FtpStart.sh >/dev/null 2>&1

2.FtpStart.sh定時要執行的sh腳本，

（做了防止重複java的機制，如果存在刪除正在執行的，執行新的）

同時在執行sh腳本時候會輸出日誌

#! /bin/ksh
. ${HOME}/.profile


count=`ps -ef|grep "FtpColoringMain.sh"|grep -v grep|wc -l`


if [ ${count} -lt 1 ]
then
   nohup sh /scmgt/shell/gt/FtpColoringMain.sh 0 2>&1 >/scmgt/shell/gt/FtpColoringMain.log  &
fi


kill -9 `ps -ef|grep "FtpWalkmanMain.sh"|grep -v grep|awk '{print $2}'`
count=`ps -ef|grep "FtpWalkmanMain.sh"|grep -v grep|wc -l`


if [ ${count} -lt 1 ]
then
   nohup sh /scmgt/shell/gt/FtpWalkmanMain.sh 3 2>&1 >/scmgt/shell/gt/ftpwalkman.log  &
fi

3.FtpWalkmanMain.sh

#! /bin/ksh
. ${HOME}/.profile


# set classpath
cp="/scmgt/shell/gt/config"


basedir=/scmgt/productServer/jboss7/standalone/deployments/productServer.war/WEB-INF/
libdir=$basedir/lib
cp="$cp:/scmgt/shell/gt/productServer.jar"


for file in `ls -1 $libdir/*.jar|grep -v "productServer.jar"`
do
cp="$cp:$file"
done
echo $cp
export CLASSPATH=$cp
java -Ddefault.client.encoding="GBK" -Dfile.encoding="GBK" -Duser.language="Zh" -Duser.region="CN" -Duser.timezone=GMT+8 com.sitech.nbc.product.service.impl.ChTFtpMusicFileServiceImpl ${1}

4.gc優化執行java

#! /bin/ksh

#set main jar

cp=$cp:$mianjar
