This section discusses tasks that you should perform after installing MySQL:
If necessary, initialize the data directory and create the MySQL grant tables. For some MySQL installation methods, data directory initialization may be done for you automatically:
Windows installation operations performed by MySQL Installer.
Installation on Linux using a server RPM or Debian distribution from Oracle.
Installation using the native packaging system on many platforms, including Debian Linux, Ubuntu Linux, Gentoo Linux, and others.
Installation on macOS using a DMG distribution.
For other platforms and installation types, including installation from generic binary and source distributions, you must initialize the data directory yourself. For instructions, see Section 9.1, “Initializing the Data Directory”.
Assign passwords to the initial
rootaccount in the grant tables, if that was not already done during data directory initialization. Passwords prevent unauthorized access to the MySQL server. For instructions, see Section 9.4, “Securing the Initial MySQL Account”.
Optionally, arrange for the server to start and stop automatically when your system starts and stops. For instructions, see Section 9.5, “Starting and Stopping MySQL Automatically”.
Optionally, populate time zone tables to enable recognition of named time zones. For instructions, see MySQL Server Time Zone Support.
When you are ready to create additional user accounts, you can find information on the MySQL access control system and account management in The MySQL Access Privilege System, and MySQL User Account Management.
