Change Standalone to WiredTiger
Starting in version 3.2, WiredTiger is the new default storage engine for MongoDB.
Starting with MongoDB 3.6, MongoDB binaries, mongod and mongos, bind to
localhost by default. From MongoDB versions 2.6 to 3.4, only the binaries from the official MongoDB RPM (Red Hat, CentOS, Fedora Linux, and derivatives) and DEB (Debian, Ubuntu, and derivatives) packages would bind to
localhost by default. To learn more about this change, see Localhost Binding Compatibility Changes.
The tutorial runs mongodump and mongorestore from the same host as the mongod they are connecting to. If run remotely, mongodump and mongorestore must specify the ip address or the associated hostname in order to connect to the mongod.
You must be using MongoDB version 3.0 or greater in order to use the WiredTiger storage engine. If using an earlier MongoDB version, you must upgrade your MongoDB version before proceeding to change your storage engine. To upgrade your MongoDB version, refer to the appropriate version of the manual.
With the WiredTiger storage engine, using XFS for data bearing nodes is recommended on Linux. For more information, see Kernel and File Systems.
If mongod is already running, you can skip this step.
mongodump --out <exportDataDestination>
Specify additional options as appropriate, such as username and password if running with authorization enabled. See mongodump for available options.
Create a data directory for the new mongod instance that will run with the WiredTiger storage engine.
mongod must have read and write permissions for this directory.
mongod with WiredTiger will not start with data files created with a different storage engine.
mongod --storageEngine wiredTiger --dbpath <newWiredTigerDBPath> --bind_ip localhost,<ipaddresses>
Specify additional options as appropriate. See mongorestore for available options.
