Assertion: 18 {code: 18, OK: 0.0, errmsg: & quot; auth fails & quot;}, assertionerrmsg

Assertion: 18 {code: 18, OK: 0.0, errmsg: "auth fails"}, assertionerrmsg

When auth is enabled, mongodump is executed and mongorestore has the following error: "assertion: 18 {code: 18, OK: 0.0, errmsg:" auth fails "}"

Actually, authentication fails.

Run mongodump -- help to find the problem. Just add the authenticationDatabase.

# Export dump-u root-p passwd -- authenticationDatabase admin-d test-o/mnt/mongdb

Mongorestore-u root-p passwd -- authenticationDatabase admin-d test/mnt/mongdb

Note: If the test is used, it is best to use -- authenticationDatabase admin, the actual production environment, it is best to create an account job
