Linux使用自定义脚本实现部署SpringBoot(jar包)项目

我们将需要进行部署的jar包上传到服务器，比如工作目录为/root/jars

编写一个自定义的启动脚本，便于直接启动

vim /root/jars/start.sh

内容：

#!/bin/sh
export LANG="en_US.UTF-8"
cd /root/jars
runMessage=`ps aux | grep `cat pidfile.txt``
projectStartCommand="/usr/local/java/jdk1.8.0_131/bin/java -jar demo.jar"
if [[ $runMessage == *$projectStartCommand* ]]
then
    echo "Application has starting ,restarting..."
    kill -9 `cat pidfile.txt`
    nohup /usr/local/java/jdk1.8.0_131/bin/java -jar demo.jar -java.tmp.dir=/root/jars/temp >/dev/null 2>&1 & echo $! > pidfile.txt
else
    echo "Application has stopped ,starting..."
    nohup /usr/local/java/jdk1.8.0_131/bin/java -jar demo.jar -java.tmp.dir=/root/jars/temp >/dev/null 2>&1 & echo $! > pidfile.txt
fi

脚本说明：

cd /root/jars：jar包所在目录projectStartCommand：脚本的前缀命令行/usr/local/java/jdk1.8.0_131/bin/java：jdk路径demo.jar：需要运行的jar包名称pidfile.txt：pid存放位置

vim /root/jars/stop.sh

内容：

#!/bin/sh
cd /root/jars
PID=$(cat pidfile.txt)
if [ ${PID} ]; 
then
    echo 'Application is stpping...'
    echo kill $PID DONE
    kill $PID
else
    echo 'Application is already stopped...'
fi

脚本说明：

cd /root/jars：jar包所在目录

启动或者重启：sh start.sh
停止：sh stop.sh
