You can kill the previous mongodinstance and start the new one.

您可以杀死前一个mongod实例并启动新的实例。

To kill the previous mongod instance, first search for a list of tasks running on your machine by typing,

要杀死之前的 mongod 实例，首先通过键入以下命令搜索在您的机器上运行的任务列表，

sudo lsof -iTCP -sTCP:LISTEN -n -P

Search for mongod COMMANDand its PIDand type,

搜索 mongod COMMAND及其PID和类型，

sudo kill <mongo_command_pid>

Now start your mongod instance by typing,

现在输入以下命令启动您的 mongod 实例，

mongod

You can see MongoDB running successfully.

可以看到MongoDB运行成功。

You already have a process running in the port 27017which is used by mongodb. So either you need to stop the process in that port or try with different port number.

你已经在该端口运行的进程27017，其使用mongodb。因此，您要么需要停止该端口中的进程，要么尝试使用不同的端口号。

Try mongod --port 27018

尝试 mongod --port 27018

You can change the port number of your choice.

您可以更改您选择的端口号。

EDIT:

编辑：

You can also just stop all the running instances of mongo server using sudo killall mongodas mentioned by @Dassi Orleando in the comments. And run mongod

您也可以使用sudo killall mongod@Dassi Orleando 在评论中提到的方式停止所有正在运行的 mongo 服务器实例 。并运行mongod

如果您使用的是 mongodb 版本 4.*

in default settings, there should be a "db" folder "/data/db" having the necessary permission.

在默认设置中，应该有一个具有必要权限的“db”文件夹“/data/db”。

如果没有然后运行

brew services start mongodb

方法：

• previously have run mongodb
  • probablyuse default port 27017

• 以前运行过mongodb
  • 可能使用默认端口27017

Solution

解决方案

(most case) kill and restart mongod

（大多数情况下）杀死并重新启动 mongod

kill mongod

杀死蒙戈

two method:

两种方法：

• use killall
  • killall mongod
• kill by PID
  • find mongod PID
    • method 1: ps aux | grep mongod
    • output can see like this: limao 425 ... /usr/local/opt/mongodb-community/bin/mongod --config /usr/local/etc/mongod.conf
    • method 2: lsof -iTCP -sTCP:LISTEN -n -P
    • output can see like this: mongod 425 limao .. TCP 127.0.0.1:27017 (LISTEN)
  • kill by PID: kill -9 425

• 使用killall
  • killall mongod
• 通过PID杀死
  • 找到mongod PID
    • 方法一： ps aux | grep mongod
    • 输出可以是这样的： limao 425 ... /usr/local/opt/mongodb-community/bin/mongod --config /usr/local/etc/mongod.conf
    • 方法二： lsof -iTCP -sTCP:LISTEN -n -P
    • 输出可以是这样的： mongod 425 limao .. TCP 127.0.0.1:27017 (LISTEN)
  • 通过PID杀死： kill -9 425

re-start mongod

    • for install community version in Mac by: brew install mongodb-community

• 大多数情况： mongod
• 一些特殊情况
  • brew services start mongodb-community
    • 通过以下方式在 Mac 中安装社区版本： brew install mongodb-community

(for some people) run with another port

（对于某些人）与另一个端口一起运行

• run with another port: mongod --port 27018
  • onlyfor those want to run multiple mongod server same time

• 使用另一个端口运行： mongod --port 27018
  • 仅适用于那些想要同时运行多个 mongod 服务器的人

Additional Note

附加说明

which port the running mongodb is using?

正在运行的 mongodb 正在使用哪个端口？

 lsof -iTCP -sTCP:LISTEN -n -P
COMMAND     PID  USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
mongod      425 limao   10u  IPv4 0xab744305e75263cf      0t0  TCP 127.0.0.1:27017 (LISTEN)

Server was restarted yesterday and then this happened.

I solved it pasting the command below into the command line in order to close mongo's server.

我解决了它，将下面的命令粘贴到命令行中以关闭 mongo 的服务器。

sudo pkill -f mongod

"sudo" (Super User Do) runs the command admin permissions, so it will ask you for your user password

“sudo”（超级用户 Do）运行命令管理员权限，所以它会询问你的用户密码

回答by Jasmeet Singh Chhabra

Make Sure the error is of the port , if using macos catalina there is a reported issue for ~/data/db which also causes this.

确保错误出在端口上，如果使用 macos catalina，则会报告 ~/data/db 的问题，这也会导致此问题。

回答by Khushwant kodecha

Just this single command

只是这个单一的命令

sudo pkill -f mongod

sudo pkill -f mongod

回答by AD Rai

This may sound obvious but you should check if mongodb is already running. So instead of first starting the the DB by running:

这听起来很明显，但您应该检查 mongodb 是否已经在运行。因此，而不是首先通过运行启动数据库：

sudo mongod

Try directly running:

直接运行试试：

mongo
