Exception:connect failed

Workaround:

1. Go to the/data/db directory and delete the Mongo.lock file

2. Enter the/mongodb/bin directory and execute the./mongod

3. Re-open a window to execute./mongo--dbpath=/data/platform/mongodb/data/db/

Note that the DB path is added to the boot, otherwise the startup fails. You also need to consider permissions issues.

4. Start successfully
