mysql安装方法这里就不在介绍,网上有很多教程
环境介绍:
A主机: win2008_x64+mysql5.7.10 64位,ip192.168.7.180
B主机: win2008_x64+mysql5.7.10 64位,ip192.168.7.181
1、首先配置my.ini文件,两台主机都需要配置(一般在mysql安装的目录下面)
A主机:my.ini,[mysqld]节点下添加如下信息
log-bin=mysql-bin server-id=181
B主机:my.ini,[mysqld]节点下添加如下信息
log-bin=mysql-bin server-id=180
添加如上配置后都需要重起两台主机的mysql服务。
2、创建Replication用户
A主机上执行如下命令:
grant replication client,replication slave on *.* to ‘repl‘@‘192.168.7.181‘ identified by ‘12345678‘
B主机上执行如下命令:
grant replication client,replication slave on *.* to ‘repl‘@‘192.168.7.180‘ identified by ‘12345678‘
3、查看两台主机的mysql bin log位置
首先将两台主机mysql中的表锁定
FLUSH TABLES WITH READ LOCK;
FLUSH TABLES WITH READ LOCK; 代表锁定表,禁止所有操作。防止bin log位置发生变化。
查看A主机bin log位置
SHOW MASTER STATUS;
A主机结果
查看B主机的bin log位置
SHOW MASTER STATUS;
B主机结果
记录下A主机结果,和B主机结果
然后再解除两台主机mysql table的锁定
Unlock Tables;
4、开始设置 Slave Replication
A主机执行如下命令:
STOP SLAVE; CHANGE MASTER TO MASTER_HOST = ‘192.168.7.181‘, MASTER_USER = ‘repl‘, MASTER_PASSWORD = ‘12345678‘, MASTER_LOG_FILE = ‘mysql-bin.000001‘, MASTER_LOG_POS = 467; START SLAVE;
B主机执行如下命令:
STOP SLAVE; CHANGE MASTER TO MASTER_HOST = ‘192.168.7.180‘, MASTER_USER = ‘repl‘, MASTER_PASSWORD = ‘12345678‘, MASTER_LOG_FILE = ‘mysql-bin.000001‘, MASTER_LOG_POS = 315; START SLAVE;
5、查看两台主机是否设置成功
Show Slave Status;
如果两台主机Slave_IO_Running 和Slave_SQL_Running都为YES代表设置成功。可以进行数据库操作了
