Master Server (Primary)

Folgende Schritte sind erforderlich, um einen DATA Server als Master zu konfigurieren.

Als erstes muss ein entsprechendes Konfigurationsmodul erstellt werden. Dies erfolgt mit folgendem Befehl.

ACHTUNG:

  • die server_id sind pro Master Server unterschiedlich 
  • Der Parameter auto_increment_offset ist pro Master Server unterschiedlich

Als nächstes wird ein Benutzer angelegt, mit dem sich die Slave-Server mit dem Master-Server verbinden können - <password> mit dem entsprechenden Passwort ersetzen.

mysql -u root -p<password> -v -e"GRANT REPLICATION SLAVE ON *.* TO 'repl'@'%'"
mysql -u root -p<password> -v -e"FLUSH PRIVILEGES"



Im Anschluss muss der MySQL-Server neu gestartet werden, damit alle Einstellungen übernommen werden:

Slave Server

Folgende Schritte sind erforderlich, um einen DATA-Server als Slave zu konfigurieren. Es handelt sich hierbei um eine unverschlüsselte Replikation. Eine verschlüsselte Replikation kann gemäß https://www.thomas-krenn.com/de/wiki/MySQL_Verbindungen_mit_SSL_verschl%C3%BCsseln umgesetzt werden.

Als erstes muss ein entsprechendes Konfigurationsmodul erstellt werden. Dies erfolgt mit folgendem Befehl.

ACHTUNG:

  • die server_id sind pro Slave Server unterschiedlich, und sind bewusst abseits von 100 gehalten, damit die nicht mit Master-IDs kollidieren.
