Mysql 5.7主从
安装忽略，参考我前面的博客。从库克隆主库，克隆主数据库后，需要修改 server-id和 /data/mysql/auto.cnf 中的UUID， 修改pid文件名字修改my.cnf
master: 只发送
binlog-do-db=autoops
slave: 只接受
replicate-do-db=autoops
主库设置：
配置文件开启log-bin=mysql-bin 从库一般开启
mysql> show variables like 'log_bin%';
+---------------------------------+-------+
| Variable_name | Value |
+---------------------------------+-------+
| log_bin | ON |
mysql> grant replicationslaveon *.*to 'rep'@'192.168.10.%'identifiedby '123456';
mysql> flush privileges;
主库:
mysqldump-uroot -p -Bautoops --events --master-data=2 --single-transaction > rep.sql 查看req.sql 记录MASTER_LOG_FILE和 MASTER_LOG_POS
22 -- CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000009', MASTER_LOG_POS=1564447;注意：innodb用 –single-transaction, myisam需要用 –lock-all-tables。scp rep.sql root@192.168.10.36:/root 从库:
mysql -uroot -p123456 < /opt/rep.sqlCHANGE 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;
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
