PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER!
To do so, start the server, then issue the following commands:

  /usr/bin/mysqladmin -u root password 'new-password'
  /usr/bin/mysqladmin -u root -h mcctb password 'new-password'

Alternatively, you can run:
  /usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.
.....Output truncated.....
WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

                                                           [  OK  ]
Starting mysqld:                                           [  OK  ]

  8. Vérifiez que le serveur MySQL est en cours d'exécution :

    [root@mcctb ~]# service mysqld status

    mysqld (pid  2739) is running...

  9. Configurez les paramètres de sécurité et de mot de passe :

    [root@mcctb ~]# mysql_secure_installation

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

 In order to log into MySQL to secure it, we'll need the current
 password for the root user.  If you've just installed MySQL, 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):   <== on default install
                                                         hit enter here
 OK, successfully used password, moving on...

 Setting the root password ensures that nobody can log into the MySQL
 root user without the proper authorization.

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

 By default, a MySQL installation has an anonymous user, allowing anyone
 to log into MySQL 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, MySQL 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...
 ERROR 1008 (HY000) at line 1: Can't drop database 'test';
 database doesn't exist
  ... Failed!  Not critical, keep moving...
  - 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!

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

 Thanks for using MySQL!

Activez le paramètre de démarrage automatique MySQL

Vous devez vérifier que la fonction de démarrage automatique est activée pour le démon MySQL. L'activation du démon MySQL redémarre automatiquement MySQL si le système sur lequel réside le logiciel MetroCluster Tiebreaker. Si le démon MySQL n'est pas en cours d'exécution, le logiciel disjoncteur d'attache continue à fonctionner, mais il ne peut pas être redémarré et des modifications de configuration ne peuvent pas être effectuées.

Étape

  1. Vérifiez que MySQL est activé pour démarrer automatiquement lors du démarrage :

    [root@mcctb ~]# systemctl list-unit-files mysqld.service

    UNIT FILE          State
------------------ ----------
mysqld.service     enabled

    Si MySQL n'est pas activé pour démarrer automatiquement au démarrage, consultez la documentation MySQL pour activer la fonction de démarrage automatique pour votre installation.

Installez le serveur MariaDB sur Red Hat Enterprise Linux 8

Vous devez installer le serveur MariaDB sur votre système hôte avant d'installer ou de mettre à niveau le logiciel disjoncteur d'attache. Pour Red Hat Enterprise Linux 7 ou CentOS 7, Installez MySQL Server.

Avant de commencer

Votre système hôte doit être exécuté sous Red Hat Enterprise Linux (RHEL) 8.
