3. Start the service

MongoDB's data is stored in the db directory of the data directory, but this directory is not automatically created during installation, so you need to manually create the data directory and the db directory.

Note:

(1) / data/db is the default startup database path for MongoDB. The custom specified path is configured with the parameter-dbpath.

(2) check the directory permissions after creating the directory, otherwise the startup will fail.

(3) because mongodb takes up disk space, check the available space to configure the data and log storage location (df-h), and reserve about 4G. If you add the-- smallfiles option when starting, it will only take up about 400MB.

Start:

[test@localhost bin] $. / mongod-- dbpath=/mongodb/db-- logpath=/mongodb/log/mongodb.log-- fork-- port=270172018-10-16T13:35:44.345+0800 I CONTROL [main] Automatically disabling TLS 1.0, to force-enable TLS 1.0 specify-- sslDisabledProtocols' none'about to fork child process, waiting until server is ready for connections.forked process: 1415child process started successfully, parent exiting
