====== MariaDB ======

===== Introduction =====


===== Installation =====

  * L'installation sous un système basé RHEL n'est pas identique à Debian. Par exemple sur CentOS il faudra lancer un utilitaire pour faire la configuration "post-installation" tandis que sous Debian, la configuration se fait durant l'installation et demande le mot de passe root.

  * <code bash>
apt-get install mariadb-server mariadb-client
ou
yum install 
</code>

===== Configuration =====

  * <code bash>systemctl enable mariadb
systemctl start mariadb
</code>
  * <code bash>
/usr/bin/mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!   

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.                              

Enter current password for root (enter for none): 
OK, successfully used password, moving on...      

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.                           

Set root password? [Y/n] Y
New password:             
Re-enter new password:    
Password updated successfully!
Reloading privilege tables..  
 ... Success!                 


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for    
them.  This is intended only for testing, and to make the installation   
go a bit smoother.  You should remove them before moving into a          
production environment.                                                  

Remove anonymous users? [Y/n] Y
 ... Success!                  

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] Y
 ... Success!                        

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.                          

Remove test database and access to it? [Y/n] Y
 - Dropping test database...                  
 ... Success!                                 
 - Removing privileges on test database...    
 ... Success!                                 

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] Y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

===== Utilisation =====


====Création d'une première base de données====

  * <code sql>
mysql -u root -p
CREATE DATABASE bddtest CHARACTER SET 'utf8';
</code>


====Création d'un utilisateur====

  * <code sql>
mysql -u root -p

CREATE USER 'william'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON bddtest.* TO 'william'@'localhost';
flush privileges;
</code>


====Import d'une base====

  * <code sql>
 mysql -u william -ppassword bddtest < dump.sql
</code>


====Activer le log de connexion====

  * Utilise pour avoir un historique des tentatives de connexions ou bien détecter les applications mal paramétrés.<code sql>
 mysql -u william -ppassword bddtest < dump.sql
