17. Basic usage Basic usage of MySQL 5 MySQL

18. Preview Define an admin password Manage users Create/Delete a database Administration tools Basic usage

19. Define a root password By default the root password is empty Adding a password for the root account : or with mysqladmin command: An user exists once he has rights on a table # mysql -u root mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION; mysql> FLUSH PRIVILEGES; # mysql -u root mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION; mysql> FLUSH PRIVILEGES; Basic usage # mysqladmin -u root password

20. Listing existing users Basic usage A simple SQL statement : mysql> SELECT user,password,host FROM mysql.user; +---------+------------+-------------------+ | user | password | host | +---------+------------+-------------------+ | root | *A4E990E4… | localhost | | root | | Arbalest | | supinfo | *06CDF16C… | linux.supinfo.com | +---------+------------+-------------------+ 3 rows in set (0.01 sec)‏ mysql> SELECT user,password,host FROM mysql.user; +---------+------------+-------------------+ | user | password | host | +---------+------------+-------------------+ | root | *A4E990E4… | localhost | | root | | Arbalest | | supinfo | *06CDF16C… | linux.supinfo.com | +---------+------------+-------------------+ 3 rows in set (0.01 sec)‏

21. Create a database With mysqladmin Within MySQL client (SQL statement) # mysqladmin -p create mandriva mysql> CREATE DATABASE mandriva; Basic usage

22. Delete a database With mysqladmin Within MySQL client (SQL statement) Basic usage # mysqladmin -p drop mandriva mysql> DROP DATABASE mandriva;

23. Note Every command in basic usage is a SQL statement Basic usage

24. Administration tools Many MySQL tools are available: Installed with the server  mysql_install_db, mysql_find_rows, mysql_manager Non-free Clients  MySQL explorer, MySQL tracer Web Clients  PHPMyAdmin Basic usage

26. Replication Setting up replication with MySQL MySQL

27. Preview What’s a replication? Setting up the master Setting up the slave(s)‏ Replication

28. Overview Setting up a replication Characteristics:  Unidirectional: Master -> Slave(s)‏  Binary log file usage Element of concern: The database What for? Fault tolerance Load balancing Replication

29. Replication account Replication user creation Rights attribution  replication slave Command used  GRANT statement Replication mysql> GRANT replication slave,replication client, super,reload ON *.* TO 'user'@'%' IDENTIFIED BY 'password' mysql> GRANT replication slave,replication client, super,reload ON *.* TO 'user'@'%' IDENTIFIED BY 'password'

30. Setting up the master Configuration of the master and database archiving Configuration  Adding options log-bin : Active the creation of binary log server-id : master’s unique number Command used for manual replication Replication # cd /var/lib/mysql # tar -cvjf mysql-database.tar.bz2 test

31. Setting up the slave(s)‏ Slave configuration Configuration  Adding options master-host : master server name master-user : replication account username master-password : replication account password master-port : server port server-id : slave’s unique number (mandatory)‏ Replication

32. Setting up the slave(s)‏ Activate the replication (after creating the same database on both servers)‏ Command : Replication Mysql > LOAD DATA FROM MASTER;

33. Setting up the slave(s)‏ Uncompressing the database Command for uncompressing Replication # cd /var/lib/mysql # tar -xvjf mysql-database.tar.bz2 # cd /var/lib/mysql # tar -xvjf mysql-database.tar.bz2

34. Note The replication is done, you just have to restart the master and the slave(s) ‏ Replication
