MongoDB安装为Windows服务的时候总报错日志文件已存在I CONTROL [main] log file "d:\mongodb\logs\mongo.log" exists; moved to "d:\mongodb\logs\mongo.log.2017-11-12T12-53-31".

报错：
I CONTROL [main] log file “d:\mongodb\logs\mongo.log” exists; moved to “d:\mongodb\logs\mongo.log.2017-11-12T12-53-31”.
我就想知道为什么总报这个错误，网上查了所有方法试过了都不管用

日志：
