MongoDB使用不同的端口启动多个mongod

我不能在cmd的第二个mongod中更改端口 1我正在c:\mongodb\bin中启动mongod 我开始写cmd了

  cd c:\mongodb\bin
    mongod --port 10003

但第二种方法不起作用。 帮帮我，谢谢

这就是我所看到的错误

C:\Windows\system32> cd c:\mongodb\bin

c:\mongodb\bin>mongod --port 10003

不能在同一数据库上启动多个MongoDB进程

您需要做的是：

mongod --dbpath c:\database1 --port 27017
mongod --dbpath c:\database2 --port 27018

请记住，必须手动创建数据库文件夹

通常，如果仔细阅读错误日志，您会发现问题：

“13627无法创建/打开锁文件：\data\db\mongod.lock。

mongod实例是否已在运行？

您收到的错误消息是什么？是否在同一目录中启动它们？mongod的第二个实例将需要不同的db路径（与第一个实例使用的默认路径不同）。因此，您必须创建一个不同的数据文件夹，并指定在使用

--dbpath

启动第二个实例时，检查我前面关于

--dbpath

的评论。这就是问题所在。
