- faire passer le master en "read only"
mysql -u root -p mysql> use database; mysql> flush tables with read lock;
- stopper le slave
mysql -u root -p mysql> stop SLAVE;
- noter la position du serveur en slave
mysql -u root -p mysql> show master status\G
- sur le master (passage en slave)
mysql> CHANGE MASTER TO MASTER_HOST=, MASTER_USER='replic', MASTER_PASSWORD='PASSWORD', MASTER_PORT=3306 ,MASTER_LOG_FILE='FILE', MASTER_LOG_POS=POS;
