Is there a way to restore a replica of MongoDB?
If you copy the data set to each mongod instance and then create the replica set, MongoDB will force the secondaries to perform an initial sync. The procedures in this document describe the correct and efficient ways to deploy a restored replica set. You can also use mongorestore to restore database files using data created with mongodump.
Can a replica be connected to more than one mongod instance?
If your application connects to more than one replica set, each set must have a distinct name. Some drivers group replica set connections by replica set name. For more information on configuration options, see Configuration File Options and the mongod manual page. Connect mongosh to the mongod instance.
Can a mongod restore from a hot backup?
Starting in 4.2, if you restore from files taken via “hot” backup (i.e. the mongod is running), MongoDB can detect “dirty” keys on startup and automatically rollover the database key to avoid IV (Initialization Vector) reuse.
How to bind a standalone to a MongoDB cluster?
The command uses the standalone’s existing database path of /srv/mongodb/db0: Before binding to a non-localhost (e.g. publicly accessible) IP address, ensure you have secured your cluster from unauthorized access. For a complete list of security recommendations, see Security Checklist.
How to force a member to become primary in MongoDB?
In a mongo shell, run rs.status () to ensure your replica set is running as expected. In a mongo shell connected to the mongod instance running on mdb2.example.net, freeze mdb2.example.net so that it does not attempt to become primary for 120 seconds.
How do I connect to MongoDB from localhost?
To connect to the mongod listening to localhost on the default port of 27017, simply issue: Depending on your path, you may need to specify the path to the mongosh binary. MongoDB initiates a set that consists of the current member and that uses the default replica set configuration.
