PDF

Selon votre système d'exploitation Linux hôte, vous devez installer un serveur MySQL ou MariaDB avant d'installer ou de mettre à niveau le logiciel Tiebreaker.

Étapes

  1. Installez JDK

  2. Installer et configurer le coffre-fort

  3. Installez le serveur MySQL ou MariaDB :

    Si l'hôte Linux est

    Alors…​

    Red Hat Enterprise Linux 7/CentOS 7

    Installez MySQL Server 5.5.30 ou version ultérieure et les versions 5.6.x sur Red Hat Enterprise Linux 7 ou CentOS 7

    Red Hat Enterprise Linux 8

    Installez le serveur MariaDB sur Red Hat Enterprise Linux 8

Installez JDK

Vous devez installer JDK sur votre système hôte avant d'installer ou de mettre à niveau le logiciel Tiebreaker. Tiebreaker 1.5 et versions ultérieures prend en charge OpenJDK 17, 18 ou 19.

Étapes

  1. Connectez-vous en tant qu'utilisateur « root » ou utilisateur sudo qui peut passer en mode privilèges avancés.

    login as: root
root@mcctb's password:
Last login: Fri Jan  8 21:33:00 2017 from host.domain.com

  2. Vérifier les versions de JDK disponibles :

    yum search openjdk

  3. Installez JDK 17,18 ou 19.

    La commande suivante installe JDK 17 :

    yum install java-17-openjdk

  4. Vérifiez l'installation :

    java -version

    Une installation réussie affiche le résultat suivant :

    openjdk version "17.0.2" 2022-01-18 LTS
OpenJDK Runtime Environment 21.9 (build 17.0.2+8-LTS)
OpenJDK 64-Bit Server VM 21.9 (build 17.0.2+8-LTS, mixed mode, sharing)

Installer et configurer le coffre-fort

Si vous n'avez pas ou ne souhaitez pas utiliser le serveur Vault local, vous devez installer Vault. Vous pouvez vous reporter à cette procédure standard pour installer Vault ou consulter les instructions d'installation de Hashicorp pour obtenir d'autres instructions.

Remarque Si votre réseau comporte un serveur de coffre-fort, vous pouvez configurer l'hôte MetroCluster Tiebreaker pour qu'il utilise cette installation de coffre-fort. Si vous le faites, vous n'avez pas besoin d'installer Vault sur l'hôte.
Étapes

  1. Accédez au /bin répertoire :

    [root@mcctb] cd /bin

  2. Téléchargez le fichier zip du coffre-fort.

    [root@mcctb /bin]#  curl -sO https://releases.hashicorp.com/vault/1.12.2/vault_1.12.2_linux_amd64.zip

  3. Décompressez le fichier du coffre-fort.

    [root@mcctb /bin]# unzip vault_1.12.2_linux_amd64.zip
Archive:  vault_1.12.2_linux_amd64.zip
  inflating: vault

  4. Vérifiez l'installation.

    [root@mcctb /bin]# vault -version
Vault v1.12.2 (415e1fe3118eebd5df6cb60d13defdc01aa17b03), built 2022-11-23T12:53:46Z

  5. Accédez au /root répertoire :

    [root@mcctb /bin] cd /root

  6. Créez un fichier de configuration de coffre-fort sous /root répertoire.

    Au [root@mcctb ~] demander, copier et exécuter la commande suivante pour créer le config.hcl fichier :

    # cat > config.hcl << EOF
 storage "file" {
  address = "127.0.0.1:8500"
  path    = "/mcctb_vdata/data"
 }
 listener "tcp" {
   address     = "127.0.0.1:8200"
   tls_disable = 1
 }
EOF

  7. Démarrez le serveur Vault :

    [root@mcctb ~] vault server -config config.hcl &

  8. Exportez l'adresse du coffre-fort.

    [root@mcctb ~]# export VAULT_ADDR="http://127.0.0.1:8200"

  9. Initialiser le coffre-fort.

    [root@mcctb ~]# vault operator init

Vault initialized with 5 key shares and a key threshold of 3. Please securely
distribute the key shares printed above. When the Vault is re-sealed,
restarted, or stopped, you must supply at least 3 of these keys to unseal it
before it can start servicing requests.

Vault does not store the generated root key. Without at least 3 keys to
reconstruct the root key, Vault will remain permanently sealed!

It is possible to generate new unseal keys, provided you have a quorum of
existing unseal keys shares. See "vault operator rekey" for more information.
    Important Vous devez enregistrer et stocker les ID de clé et le jeton racine initial dans un emplacement sécurisé pour pouvoir les utiliser ultérieurement dans la procédure.

  10. Exportez le jeton racine du coffre-fort.

    [root@mcctb ~]#  export VAULT_TOKEN="<initial_root_token_id>"

  11. Déscellez le coffre-fort en utilisant trois des cinq clés créées.

    Vous devez exécuter le vault operator unseal pour chacune des trois touches :

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.

  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.
