欢迎访问我的个人博客 [https://jialaner.cn/][https_jialaner.cn]

\#功能：   
\#1、指定用户运行——未实现   
\#2、默认logs目录——可否另外指定？   
\#3、JMX监控——待实现，需要启用第二参数来指定   
\#4、设置JVM参数（指定程序运行名称、时区、内存大小、GC回收器设置、gc日志文件）   
\#5、 指定配置文件的环境变量   
\#6、start 启动时检查程序是否已经启动   
\#7、stop 停止程序、stop之前会先dump。带完善：kill失败检查，然后用kill -9, 有可能存在多个server   
\#8、status 查看程序是否运行   
\#9、restart 重启   
\#10、dump dump系统状态和jvm信息到文件中   
\#11、配置文件使用哪种方式更好？   
\#12、默认的jvm配置   
\#待补充端口占用检查   
  
\#使用：   
\#1、上传.sh脚本到服务器中,授权脚本执行权限sudo chmod +x ./app.sh   
\#2、启动示例 ./app.sh start
