Backup Types •
Hot (Online non-blocking) – Innodb Hot Backup (MySQL Enterprise Backup) – Backs up without locking InnoDB data, supports MyISAM – High Performance, Compressed, and Partial backup – Point-in-time recovery
•
Export/Import – Mysqldump tool – SELECT…INTO FILE, LOAD DATA INFILE

MySQL Security Model •
MySQL security is based on Access Control Lists (ACLs) – Connections – Queries – Operations users attempt to perform
•
SSL-encrypted connections supported between MySQL clients and servers

MySQL Privilege System •
Authenticates a user connecting from a given host and associates the user with privileges such as: – – – –
• •
SELECT INSERT UPDATE DELETE
Ability to have anonymous users Privileges for MySQL-specific functions such as: – LOAD DATA INFILE – Administrative operations – Replication
© 2010 Oracle Corporation
29
Connecting to MySQL • MySQL client expects connection parameters when accessing a MySQL server: – Host where the MySQL server is running – Username – Password
sample connection

Connecting to MySQL MySQL considers both your host name and user name Don‟t assume a user name belongs to the same person everywhere For example: bill who connects from 192.168.0.10 is not necessarily the same user as bill who connects from 192.168.0.11 Note: Wild cards - supports „User1‟@‟%‟ or „User1‟@'%.xyz.com'

MSQL sysadmin (sa) = MySQL root Accounts • • • • • •
Two accounts are created with a user name of root These are super user accounts that can do anything The initial root account passwords are blank One root account for connecting from the local host The other allows connections from any host Grant role Sysadmin = grant ALL
© 2010 Oracle Corporation
32
Job/Task Scheduler • MySQL Event Scheduler – Built-in scheduler for MySQL jobs – Ease to use, no need for OS scripts – One off or recurring/scheduled jobs
• Example: “Reorg tables on Sunday at 1 AM” – – – – – – – – – – –
DELIMITER // CREATE EVENT OPTIMIZE_TABLES ON SCHEDULE EVERY 1 WEEK STARTS '2009-03-05 1:00:00' ON COMPLETION PRESERVE DO BEGIN OPTIMIZE TABLE test.table1; OPTIMIZE TABLE test.table2; END //
