一、sh脚本内容

#!/bin/bash

SpringBoot=$2

if [ "$1" = "" ];
then
    echo -e "\033[0;31m 未输入操作名 \033[0m  \033[0;34m {start|stop|restart|status} \033[0m"
    exit 1
fi

if [ "$SpringBoot" = "" ];
then
    echo -e "\033[0;31m 未输入应用名 \033[0m"
    exit 1
fi

function start()
{
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`
    if [ $count != 0 ];then
        echo "$SpringBoot is running..."
    else
        echo "Start $SpringBoot success..."
        nohup java -server -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m -Xms1024m -Xmx1024m -Xmn512m -Xss256k -XX:SurvivorRatio=8 -XX:+UseConcMarkSweepGC -jar $SpringBoot > /dev/null 2>&1 &
    fi
}

function stop()
{
    echo "Stop $SpringBoot"
    boot_id=`ps -ef |grep java|grep $SpringBoot|grep -v grep|awk '{print $2}'`
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`

    if [ $count != 0 ];then
        kill $boot_id
        count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`

        boot_id=`ps -ef |grep java|grep $SpringBoot|grep -v grep|awk '{print $2}'`
        kill -9 $boot_id
    fi
}

function restart()
{
    stop
    sleep 2
    start
}

function status()
{
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`
    if [ $count != 0 ];then
        echo "$SpringBoot is running..."
    else
        echo "$SpringBoot is not running..."
    fi
}

case $1 in
    start)
    start;;
    stop)
    stop;;
    restart)
    restart;;
    status)
    status;;
    *)

    echo -e "\033[0;31m Usage: \033[0m  \033[0;34m sh  $0  {start|stop|restart|status}  {SpringBootJarName} \033[0m
\033[0;31m Example: \033[0m
      \033[0;33m sh  $0  start $SpringBoot \033[0m"
esac

二、使用示例

[root@izuf672oio5mc4fbyj0s0jz mp-springboot]# ./springboot.sh start vue-springboot-0.0.1-SNAPSHOT-exec.jar
Start vue-springboot-0.0.1-SNAPSHOT-exec.jar success...
[root@izuf672oio5mc4fbyj0s0jz mp-springboot]# ./springboot.sh restart vue-springboot-0.0.1-SNAPSHOT-exec.jar
Stop vue-springboot-0.0.1-SNAPSHOT-exec.jar
Start vue-springboot-0.0.1-SNAPSHOT-exec.jar success...
[root@izuf672oio5mc4fbyj0s0jz mp-springboot]# ./springboot.sh stop vue-springboot-0.0.1-SNAPSHOT-exec.jar
Stop vue-springboot-0.0.1-SNAPSHOT-exec.jar
[root@izuf672oio5mc4fbyj0s0jz mp-springboot]# ./springboot.sh status vue-springboot-0.0.1-SNAPSHOT-exec.jar
vue-springboot-0.0.1-SNAPSHOT-exec.jar is running...

[root@izuf672oio5mc4fbyj0s0jz mp-springboot]# ./springboot.sh restartd vue-springboot-0.0.1-SNAPSHOT-exec.jar
 Usage:    sh  ./springboot.sh  {start|stop|restart|status}  {SpringBootJarName} 
 Example: 
       sh  ./springboot.sh  start guoxiuzhi-test.jar

三、附录

3.1命令行启动springboot

java -server -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m -Xms1024m -Xmx1024m -Xmn512m -Xss256k -XX:SurvivorRatio=8 -XX:+UseConcMarkSweepGC -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8081,suspend=n -jar /data/app/test.jar --spring.profiles.active=dev > catalina.out 2>&1 &

3.2参数说明

-Xms1024m 设置的是JVM堆最小内存为1024m
-Xmx1024m 设置的是JVM堆最大内存为1024m
这里个问题是-Xmx指定的内存不包括jvm运行中使用的本地内存，所以如果有NIO等涉及到本地内存的情况时，该java进程占用的总内存会超过-Xmx设定的数值
-Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8081,suspend=n
设置debug模式，允许tomcat远程连接服务器调试，调试端口可指定，此处为8081
/data/app/test.jar 指定需要执行的jar包的路径
--spring.profiles.active=dev 设定SpringBoot运行环境为dev环境
大于号> catalina.out将标准输出指向指定文件catalina.out
2>&1 输出所有的日志文件
& 后台模式执行
