修改my.cnf

master: 只發送
binlog-do-db=autoops
slave: 只接受
replicate-do-db=autoops

主庫設置：

配置文件開啟 log-bin=mysql-bin 從庫一般開啟

mysql> show variables like 'log_bin%';
+---------------------------------+-------+
| Variable_name                   | Value |
+---------------------------------+-------+
| log_bin                              | ON    |


mysql> grant replication  slave  on *.*  to 'rep'@'192.168.10.%'  identified  by '123456';
mysql> flush privileges;

主庫:

mysqldump  -uroot -p    -B  autoops   --events   --master-data=2   --single-transaction   > rep.sql

查看req.sql 記錄 MASTER_LOG_FILE 和 MASTER_LOG_POS

22    -- CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000009', MASTER_LOG_POS=1564447;

註意：innodb用       –single-transaction,       myisam需要用 –lock-all-tables。

scp rep.sql   [email protected]:/root

從庫:

mysql     -uroot -p123456    <   /opt/rep.sql

CHANGE MASTER TO
MASTER_HOST='192.168.10.29',
MASTER_PORT=3306,
MASTER_USER='rep',
MASTER_PASSWORD='123456',
MASTER_LOG_FILE='mysql-bin.000009',
MASTER_LOG_POS=1486295;

/data/master.info //生成的文件

mysql> start slave;

mysql> show slave status\G;
