无法启动MongoDB副本集：各种错误

Question

首先，我为该组的3个成员设置配置文件并尝试启动它，如下所示：

它抱怨mongod实际上没有--replSet进程。这就是为什么我尝试在不同的终端上启动副本集并获得以下错误的原因：

Answer 1

您的问题是您正在使用另一个mongod进程正在使用的dbPath启动mongod。正如错误消息所示：

exception in initAndListen: 13627 Unable to create/open lock file: \data\rs0\mongod

看一下你正在运行的进程并确保你没有隐藏某个地方的mongod。在您停止进程之后，使用正确的replSet选项

启动您的三个mongod
