无法更改mongodb的dbpath

Question

我无法为mongoDB (WSL2 Arch)更改dbpath，我运行以下命令：

 sudo mongod --dbpath /home/arijit/work/data/

数据文件夹的权限：

drwxr-xr-x  2 mongodb mongodb 4096 Aug  9 10:00 data/

我收到的错误消息：

我尝试删除/var/lib/mongodb/mongod.lock文件，然后运行命令更改dbpath，但结果相同。

Answer 1

基于@Gibbs答案，该错误意味着端口已经在使用另一个进程。你可以用

ps aux | grep -v grep | grep mongod

输出应该如下所示

user 73044   0.2  0.2  5501992  17176   ??  S    11:02AM   0:07.32 mongod --config /usr/local/etc/mongod.conf --fork

其中73044是PID。

然后，您可以用

kill -9 <PID> # Replace <PID> with the PID provided in the output...in my case 73044

现在，您可以尝试重新启动mongod

mongod --dbpath /home/arijit/work/data/

Answer 2

错误是不同的

{“错误”：{“代码”：9001，"codeName":"SocketException"，“errmsg”：“已在使用的地址”}}

这意味着端口已经被另一个进程使用了。

试着检查ps -ef | grep portConfigured。默认的mongo端口是27017

如果端口中正在运行另一个进程，那么在启动mongo时必须通过传递--port portNumber来更改端口。
