windows下安装mysql5.6.13的主从复制
如下操作均在vmware 虚拟机中winows xp 测试成功
中间走了很多弯路,网上的很多资料都是针对5.1以前的版本,在新版中根本无法使用,所以根据自己的实践整理了这篇文章
主服务:192.168.131.21
从服务器:192.168.131.22
1、主机的配置
my.ini中配置:
server-id = 1
binlog_format = "ROW"
log-bin=mysql-bin
启动服务后进入mysql命令行执行如下操作
GRANT ALL ON *.* TO 'slave1'@'192.168.131.22' IDENTIFIED BY '123456';
如果需要进行某个数据库的同步的话,最好只创建对应数据库的权限,如:
GRANT ALL ON test1.* TO 'slave1'@'192.168.131.22' IDENTIFIED BY '123456';
这样只会同步该数据库的内容。
2、从服务器设置
my.ini:
server-id = 2
relay-log-purge=1
skip-slave-start
replicate-ignore-db=mysql #此处为不同步mysql数据库的内容此处如果为多数据库的话中间以逗号分开
然后启动mysql 进入命令行 执行如下命令
CHANGE MASTER TO MASTER_HOST='192.168.131.21', MASTER_USER='slave1', MASTER_PASSWORD='123456';
3、启动主从复制
首先启动主服务器的服务
其次启动从服务器的服务
然后在从服务器命令行执行
start slave;
然后执行如下命令 查看从服务器状态
SHOW SLAVE STATUS\G

还要注意的是:
我在做从服务器时,是停止服务,然后整体复制的data目录,如果不进行任何修改的话,会出现如下提示:
[ERROR] Slave I/O: Fatal error: The slave I/O thread stops because master and slave have equal MySQL server UUIDs; these UUIDs must be different for replication to work. Error_code: 1593
121122 17:40:58 [Note] Slave I/O thread exiting, read up to log 'FIRST', position 4
这个时候,应该删除data目录下的auto.cnf,然后重启服务
执行 start slave;即可
之后在主服务器上创建数据库
再从服务器上就可看到同步过来的数据了
还有如果更改从服务器的机器名的话 可这样这样执行命令:
stop slave;
reset slave;
start slave;
