On-call engineers may also use this account to access the server during an incident with certificate authentication and must request access using just-in-time (JIT) processes. This is a system account created by Microsoft to manage the server to conduct monitoring, backups, and other regular maintenance. GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, PROCESS, REFERENCES, INDEX, ALTER, SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER ON *.* TO WITH GRANT OPTION Īll Azure Database for MySQL servers are created with a user called "azure_superuser". See an example below: CREATE USER IDENTIFIED BY 'StrongPassword!' To restrict the type of operations a user can run on the database, you need to explicitly add the operations in the GRANT statement. Mysql -host .com -database testdb -user db_user -p Mysql -host .com -database testdb -user -p See how to connect for Single server and Flexible server below. Use your own server name, database name, and user name. When you use this command, you'll be prompted for the user's password. This example shows the mysql command line. Sign in to the server, specifying the designated database and using the new user name and password. SHOW GRANTS FOR to the database with new user Run the SHOW GRANTS MySQL statement to view the privileges allowed for user db_user on testdb database. CREATE USER IDENTIFIED BY 'StrongPassword!' Now that the database is created, you can create with a non-admin user with the CREATE USER MySQL statement. It then creates a new user in the MySQL service and grants all privileges for the new database schema (testdb.*) to that user. This SQL code creates a new database named testdb. Replace the placeholder value testdb with your database name. Replace the placeholder value db_user with your intended new user name. If you're not sure how to connect, see connect and query data for Single Server or connect and query data for Flexible Server.Įdit and run the following SQL code.
