You are setting up a new installation of MySQL Server 5.7 (a GA release.) You have used a ZIP or TAR package to ensure that the mysqld binary, along with its support files, such as plug-ins and error messages, now exist on the host.

Assume that the default datadir exists on the host. You installed the binary in the default location (the default —basedir value) for your operating system.

Which step should you perform before defining your own databases and database tables?

A. Execute a command with a minimal form of: mysqld —initialize

B. Register mysqld as a service that will start automatically on this host machine.

C. Create a configuration file containing default-storage-engine=InnoDB.

D. Set an exception in the host machine’s firewall to allow external users to talk to mysqld.http://www.cndba.cn/hbhe0316/article/22745http://www.cndba.cn/hbhe0316/article/22745
