我正在尝试启动MongoDB，但终端返回以下错误：

如果这很重要，我正在使用Laravel代客。
您似乎已经在要启动mongoDB的端口上运行了一个进程：
listen(): bind() failed Address already in use for socket: 0.0.0.0:27017
2017-02-06T16:26:27.038+0000 E NETWORK [initandlisten] addr already in use
您可以尝试使用以下命令终止在该端口上运行的进程：sudo killsudo lsof-t-i： 27017
或者如果您有另一个程序使用该端口，则为mongoDB定义另一个端口。
要在其默认端口（27017）以外的端口上运行mongob，请在从终端启动mongob时使用--port 27018参数
如果您使用的是mac，那么您可以简单地杀死在端口27017上运行的进程，这在大多数情况下是mongoDB进程。
只需运行命令。
npx kill-port 27017
之后，您可以像往常一样运行mongod命令。
或者如果您使用的是windows，请按照以下步骤操作
netstat-ano|findstr： 27017taskkill/PID 享受！
这对我很管用
然后我换了MongoDB的港口
sudo mongod --port 27018
现在mongod服务器暂时运行
sudo mongod
