怎么 利用MySQL master slave

本篇内容介绍了“怎么使用MySQL master/slave”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

Master my.ini

basedir = D:\mysql_test\mysql-5.7.17-master

datadir = D:\mysql_test\mysql-5.7.17-master\data

port = 3306

log-bin=mysql-bin

server_id=1

binlog-ignore-db=information_schema

binlog-ignore-db=cluster

binlog-ignore-db=mysql

binlog-do-db=test

Slave my.ini

basedir = D:\mysql_test\mysql-5.7.17-slave

datadir = D:\mysql_test\mysql-5.7.17-slave\data

port = 3307

log-bin=mysql-bin

server-id=2

binlog-ignore-db=information_schema

binlog-ignore-db=cluster

binlog-ignore-db=mysql

replicate-do-db=test

replicate-ignore-db=mysql

log-slave-updates

slave-skip-errors=all

slave-net-timeout=60

Master 运行

mysql> CREATE USER 'rep'@'%' IDENTIFIED BY 'rep';

mysql> GRANT FILE ON *.* TO 'rep'@'%' IDENTIFIED BY 'rep';

mysql> GRANT REPLICATION SLAVE ON *.* TO 'rep'@'%' IDENTIFIED BY 'rep';

mysql> FLUSH PRIVILEGES;

mysql> show master status;

+------------------+----------+--------------+----------------------------------+-------------------+

| File      | Position | Binlog_Do_DB | Binlog_Ignore_DB        | Executed_Gtid_Set |

+------------------+----------+--------------+----------------------------------+-------------------+

| mysql-bin.000002 |  4570 | test    | information_schema,cluster,mysql |         |

+------------------+----------+--------------+----------------------------------+-------------------+

Slave 运行

mysql> CREATE USER 'rep'@'%' IDENTIFIED BY 'rep';

mysql> change master to master_host='localhost',master_user='rep',master_password='rep',master_log_file='mysql-bin.000002', master_log_pos=4570;

mysql> start slave;

mysql> show slave status;

Slave_IO_Running 和 Slave_SQL_Running都是 Yes 表示成功。

Master创建数据库，创建表，添加数据，会自动复制到Slave。
