Springboot shell启动脚本

#!/bin/sh
## java 此处是指定jdk启动
export JAVA_HOME=/usr/local/java/jdk1.8.0_181
export JRE_HOME=$JAVA_HOME/jre
 
##此处是打包的jar包名称，不带.jar后缀
API_NAME=demo
##项目路径
SERVICE_DIR=/usr/local/service/exchange-demo
##临时目录，如果不指定该目录(使用默认路径)可能会导致启动报错
TMP_DIR=$SERVICE_DIR/temp
##完整jar包名称
JAR_NAME=$API_NAME\.jar
##PID  代表是PID文件
PID=$API_NAME\.pid
## 此处是本地ip，此处使用python获取本地ip，服务器需确保安装python环境，把括号内的命令复制到服务器执行一下看下获取到的ip是否正确
LOCAL_IP=$(python2 -c "import socket;print([(s.connect(('8.8.8.8', 53)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1])")

## 进入执行目录 
cd $SERVICE_DIR
## 创建临时目录
mkdir -p $TMP_DIR
