mysql

server-id                       = 151

log-bin                         =/opt/soft/mysql/binlog/mysql-bin

binlog_format                    = MIXED

2 獲得基礎備份

/opt/soft/mysql/bin/mysqldump -p123456 --single-transaction --master-data=2 AdDataCenter | gzip >AdDataCenter.sql.gz

GRANT REPLICATION SLAVE ON *.* TO'repat152'@'192.168.%'  IDENTIFIED BY'123456';

4到從機上恢復數據庫 www.2cto.com

gzip –cd AdDataCenter.sql.gzip | opt/soft/mysql/bin/mysql –p123456 AdDataCenter

5 設置復制庫選項

gzip -cd AdDataCenter.sql.gz | grep -i"CHANGE MASTER TO"

得到binlog 文件和binlog pos

CHANGEMASTER TO MASTER_HOST='master_host_name',MASTER_USER='replication_user_name',MASTER_PASSWORD='replication_password',MASTER_LOG_FILE='recorded_log_file_name',ASTER_LOG_POS=recorded_log_position;
