springboot打成jar包后,可直接用java -jar app.jar 启动,或者使用 nohup java -jar app.jar & 后台启动,也可以将 jar包链接到/etc/init.d/下,作为服务启动 ,这两种启动方式各有缺点,可以用一个shell脚本解决这个问题

将文章最后脚本保存为sh文件,比如 spring-boot.sh
,跟jar包放在同一目录下,给与执行权限 chomd 777 spring-boot.sh.使用方法如下:

切换到jar目录,执行:

sh spring-boot.sh start app.jar --spring.profiles.active=peer1

解释:
第一个参数: 启动命令 (start,stop,restart,status)
第二个参数: 需启动的jar包
第三个参数: 启动参数(可不加)

脚本中的jvm参数可以根据需求修改

#!/bin/bash

SpringBoot=$2

#启动参数
START_OPTS=$3

#JVM参数
JVM_OPTS="-Dname=$SpringBoot  -Duser.timezone=Asia/Shanghai -Xms512M -Xmx512M -XX:PermSize=256M -XX:MaxPermSize=512M -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDateStamps  -XX:+PrintGCDetails -XX:NewRatio=1 -XX:SurvivorRatio=30 -XX:+UseParallelGC -XX:+UseParallelOldGC"
