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

主库:

mysqldump  -uroot -p    -B  autoops   --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.sql

CHANGE MASTER TOMASTER_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
