MySQL Replication

Open two windows to the Master Server and one window to the Slave Server

On the MASTER Server MAIN WINDOW

1. # service mysqld stop
2. # vi /data/chroot/etc/my.cnf

	log-bin         = mysql-bin
	server-id       = 1

3. # service mysqld start

On the SLAVE Server

1. # service mysqld stop
2. # vi /data/chroot/etc/my.cnf

	server-id       = 2

3. service mysqld start

On the MASTER Server MAIN WINDOW

1. # mysql -p -uroot
2. mysql> GRANT REPLICATION SLAVE ON *.* TO 'mysql-ha'@'<IP Address of Slave>' IDENTIFIED BY '<Password>';
3. mysql> FLUSH PRIVILEGES;
4. mysql> FLUSH TABLES WITH READ LOCK;

On the MASTER Server SECOND WINDOW

1. Take a dump of the MySQL environment (optional).
   1. # mysqldump -p -u root --all-databases > alldb.sql
   2. SCP this information over to the slave server.
2. # mysql -p -uroot
3. mysql> SHOW MASTER STATUS;
4. mysql> UNLOCK TABLES;

On the SLAVE Server

1. Restore the backup from the master server (optional).
   1. # mysql -p -uroot < alldb.sql
2. # mysql -p -uroot
3. mysql> CHANGE MASTER TO MASTER_HOST='<IP Address of Master>', MASTER_USER='mysql-ha', MASTER_PASSWORD='<Password>', MASTER_LOG_FILE='mysql-bin.<######>', MASTER_LOG_POS=<###>;
4. mysql> START SLAVE;

On the MASTER Server MAIN WINDOW

1. mysql> UNLOCK TABLES;
