脚本
以下为shell脚本内容，在自己电脑新建QuickDeploy.sh文件，并将内容复制到sh文件中即可。
#!/bin/bash
#这里替换为你自己的执行程序(jar包)存放路径
APP_PATH=/home/admin
#这里替换为你自己的执行程序(jar包)文件名，启动方法中修改启动参数
APP_NAME=demo.jar
#这里替换为你自己的执行程序(jar包)的启动日志文件路径+文件名
APP_LOG_PATH=/home/admin/nohup.out
#使用说明，用来提示输入参数
usage() {
echo "Usage: sh demo.sh [start|stop|restart|status]"
exit 1
}
#检查程序是否在运行
is_exist() {
pid=`ps -ef | grep $APP_NAME | grep -v grep | awk '{print $2}' `
#如果不存在返回1，存在返回0
if [ -z "${pid}" ]; then
return 1
else
return 0
fi
}
#启动方法
start() {
is_exist
if [ $? -eq "0" ]; then
echo "${APP_NAME} is already running. pid=${pid} ."
else
echo "jar path: ${APP_PATH}"
cd $APP_PATH
nohup java -Xms128m -Xmx128m -jar $APP_NAME &
tail -f $APP_LOG_PATH
fi
}
#停止方法
stop() {
is_exist
if [ $? -eq "0" ]; then
kill -9 $pid
else
echo "${APP_NAME} is not running"
fi
}
#输出运行状态
status() {
is_exist
if [ $? -eq "0" ]; then
echo "${APP_NAME} is running. Pid is ${pid}"
else
echo "${APP_NAME} is not running."
fi
}
#重启
restart() {
stop
start
}
#根据输入参数，选择执行对应方法，不输入则执行使用说明
case "$1" in
"start")
start
;;
"stop")
stop
;;
"status")
status
;;
"restart")
restart
;;
*)
usage
;;
esac使用
准备程序对脚本进行测试：
package com.example.study;
import ...;
/**
* @Description: 启动类
* @Author Lenon Jin
* @Date 2021/8/25 10:39 下午
* @Version 1.0
*/
@SpringBootApplication
@Slf4j
public class StudyApplication {
public static void main(String[] args) {
log.info("窝窝头一块钱四个嘿嘿!");
SpringApplication.run(StudyApplication.class, args);
}
}将shell文件上传至服务器，记得按照文件中注释修改jar包路径，jar包文件名，日志文件路径，文件信息：
