To illustrate, the following command grants a user global privileges to CREATE, ALTER, and DROP databases, tables, and users, as well as the power to INSERT, UPDATE, and DELETE data from any table on the server. In SQL, asterisks are special characters used to represent “all” databases or tables. You can also grant a user privileges globally by entering asterisks ( *) in place of the database and table names.
You can grant multiple privileges to the same user in one command by separating each with a comma. The PRIVILEGE value in this example syntax defines what actions the user is allowed to perform on the specified database and table.
The general syntax for granting user privileges is as follows:
#CREATE NEW USER COMMAND PROMPT PASSWORD#
Be sure to change sammy to your preferred username and password to a strong password of your choosing: Run the following command to create a user that authenticates with caching_sha2_password. The MySQL documentation recommends this plugin for users who want to log in with a password due to its strong security features. But it also prevents remote connections, which can complicate things when external programs need to interact with MySQL.Īs an alternative, you can leave out the WITH authentication_plugin portion of the syntax entirely to have the user authenticate with MySQL’s default plugin, caching_sha2_password. The auth_socket plugin mentioned previously can be convenient, as it provides strong security without requiring valid users to enter a password to access the database. You have several options when it comes to choosing your user’s authentication plugin. Wrapping both the username and host in single quotes isn’t always necessary, but doing so can help to prevent errors. If you only plan to access this user locally from your Ubuntu server, you can specify localhost. This is immediately followed by an sign and then the hostname from which this user will connect.
The following will run your MySQL client with regular user privileges, and you will only gain administrator privileges within the database by authenticating with the correct password: Note: If your root MySQL user is configured to authenticate with a password, you will need to use a different command to access the MySQL shell. This means that you need to precede the mysql command with sudo to invoke it with the privileges of the root Ubuntu user in order to gain access to the root MySQL user: This plugin requires that the name of the operating system user that invokes the MySQL client matches the name of the MySQL user specified in the command. In Ubuntu systems running MySQL 5.7 (and later versions), the root MySQL user is set to authenticate using the auth_socket plugin by default rather than with a password.
#CREATE NEW USER COMMAND PROMPT HOW TO#
This step outlines how to use the root MySQL user to create a new user account and grant it privileges. Because of this, it’s best to avoid using this account outside of administrative functions.
#CREATE NEW USER COMMAND PROMPT FULL#
This user has full privileges over the MySQL server, meaning it has complete control over every database, table, user, and so on. Upon installation, MySQL creates a root user account which you can use to manage your database. Please note that any portions of example commands that you need to change or customize will be highlighted like this throughout this guide.
