Problem Description:

Error: 14 when starting mongodb, check mongodb.log for MongoDB – Unable to unlink socket file / tmp / mongodb-27017

Cause analysis:

Check /tmp/mongodb-27017.sock, found that the owner is root

Solution:

Delete the /tmp/mongodb-27017.sock file and restart the mongod process. Check the /tmp/mongodb-27017.sock permissions again and change the ownership to the “mongodb” user.

also started successfully

Summary:

1. Check more logs, mongodb.log
2. The mongodb error column, such as 1100, is mostly due to the wrong specification of the data path and log path in the configuration file. The data path needs to be created in advance, which is a directory, and the log path also needs to be created in advance, which is a file
