Mongod not starting

Question

I cannot run mongod in my ubuntu machine. I read some blogs and stackoverflow threads suggesting to change the ownership of the /var/lib/mongodb and /var/log/mongodb folders by,

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown -R mongodb:mongodb /var/log/mongodb

but I still cant run mongod and getting the following error message.

vinayak@vinayak-Lenovo-G500:~$ mongod

..and I don't think so, my mongodb is corrupted as it is fresh install and I haven't tweaked anything in it.

Please suggest any solution. Thank you.

Answer 1

通过堆栈跟踪错误“套接字已使用地址：0.0.0.0：27017”，您可以尝试在其他端口上运行，例如mongod --port 12345

Answer 2

在终端中编写以下内容，它肯定可以工作（在macbook中对我有用）。

sudo killall -15 mongod
