Installieren Sie MetroCluster Tiebreaker 1.4-Abhängigkeiten

Beitragende
PDFs

Installieren Sie je nach Linux-Betriebssystem einen MySQL- oder MariaDB-Server, bevor Sie die Tiebreaker Software installieren oder aktualisieren.

Schritte

  1. Installieren Sie JDK.

  2. MySQL oder MariaDB Server installieren:

    Wenn der Linux-Host lautet

    Dann…​

    Red hat Enterprise Linux 7/CentOS 7

    Installieren Sie MySQL Server 5.5.30 oder höher und 5.6.x-Versionen unter Red hat Enterprise Linux 7 oder CentOS 7

    Red Hat Enterprise Linux 8

    Installieren Sie den MariaDB-Server unter Red hat Enterprise Linux 8

Installieren Sie JDK

Sie müssen JDK auf Ihrem Hostsystem installieren, bevor Sie die Tiebreaker Software installieren oder aktualisieren. Tiebreaker 1.4 und frühere Versionen unterstützen JDK 1.8.0. (JRE 8).

Schritte

  1. Melden Sie sich als „root“-Benutzer an.

    login as: root

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. Bestätigen Sie, dass MySQL-Server ausgeführt wird:

    [root@mcctb ~]# service mysqld status

    mysqld (pid  2739) is running...

  9. Konfigurieren Sie die Sicherheits- und Kennworteinstellungen:

    [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!

  10. Überprüfen Sie, ob die MySQL-Anmeldung funktioniert:

    [root@mcctb ~]# mysql -u root –p

    Enter password: <configured_password>

Aktivieren Sie die Einstellung MySQL Autostart

Sie sollten überprüfen, ob die Autostart-Funktion für den MySQL-Daemon aktiviert ist. Durch Aktivieren des MySQL-Daemon wird MySQL automatisch neu gestartet, wenn das System, auf dem die MetroCluster Tiebreaker Software ausgeführt wird, neu gestartet wird. Wenn der MySQL-Daemon nicht ausgeführt wird, wird die Tiebreaker-Software weiterhin ausgeführt, kann aber nicht neu gestartet werden und Konfigurationsänderungen können nicht vorgenommen werden.

Schritt

  1. Vergewissern Sie sich, dass MySQL beim Starten automatisch gestartet wird:

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

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

    Wenn MySQL beim Starten nicht aktiviert ist, lesen Sie die MySQL-Dokumentation, um die Autostart-Funktion für Ihre Installation zu aktivieren.

Installieren Sie den MariaDB-Server unter Red hat Enterprise Linux 8

Sie müssen MariaDB Server auf Ihrem Hostsystem installieren, bevor Sie die Tiebreaker Software installieren oder aktualisieren. Für Red hat Enterprise Linux 7 oder CentOS 7, Installieren Sie MySQL Server.

Bevor Sie beginnen

Ihr Hostsystem muss unter Red hat Enterprise Linux (RHEL) 8 ausgeführt werden.

Schritte

  1. Melden Sie sich als an root Benutzer:

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

  2. Installieren Sie den MariaDB-Server:
