The error below occurs when mongodb is started. Check the log file and find:

Possible errors:

1. Your conf file is incorrectly written, format or code, etc

2. Bindip binds both the localhost and the internal and external addresses of the server

Solution: check and write the file format, and pay attention to yaml format. Then, bindip directly accesses, allowing all access. It should be OK.

If viewing the log is this error:

Failed to set up listener: SocketException: Address already in use

ps aux | grep mongod
sudo kill -9 {port-number}
