问题排查

1.检查mqnamesrv是否启动成功

• 启动成功日志如下
  

2.检查mqbroker是否启动成功

• 启动mqbroker成功日志如下
  

发现问题

• 在bin目录下启动时mqbroker时，并没有打印成功日志，而是停留在当前执行窗口。
  
• 定位问题：启动mqbroker失败!!!

解决问题

如果是正式环境，就不要随意删除store目录啦。即使要删除，先备份哦!!!

• 启动broker失败，测试环境直接删除数据存储store目录，该目录默认在${user.home}/store
• window cmd查看：输入 echo %userprofile% 或 echo %USERPROFILE%
