Mongo服务器无法通过命令mongod --dbpath /Users/mayankpatel/data/db启动。

Question

我通过Homebrew安装了Mongo，但是当我尝试运行以下命令时：

--dbpath /Users/mayankpatel/data/db

启动Mongo服务器时，它给我返回了以下错误：

错误 - Address already in use 意味着 MongoDB 已经在运行。

Error setting up listener","attr":{"error":{"code":9001,"codeName":"SocketException","errmsg":"Address already in use"}}}

你需要关闭之前正在运行的Mongo服务器，你可以使用ps -aux | grep mongo查找。

然后，你可以使用kill -9 进程ID，例如：kill -9 2781

我尝试通过 kill -9 <PID> 来终止运行在端口 27017 上的进程，然后再次运行该命令，但它没有起作用。 - Mayank Patel

即使杀死进程后仍然出现相同的错误。 - Mayank Patel

@MayankPatel，您能否详细说明一下错误？ - Tushar Gupta - curioustushar

@MayankPatel 你有没有运行任何 ps -aux | grep mongo 进程？ - Tushar Gupta - curioustushar

@MayankPatel，你也可以这样做：首先使用 ps -ef | grep mongo 命令获取 MongoDB 进程的 PID（顺便说一下，PID 是输出中的第二个字段）。然后执行 netstat -aonp | grep your_mongo_pid_here 命令，它会告诉你 MongoDB 是否在监听端口。请按照这些步骤操作，并告诉我们结果如何，谢谢。 - RavinderSingh13
