1：主库设置

（1）修改配置文件

vi /etc/my.cnf

[mysqld]

log-bin=master-bin

server-id=1

（2）创建用户

#mysql -u root -pmysql

>create user test identified by 'test';

>grant all privileges on *.* to 'test'@'%' identified by 'test' with grant option;

//赋予主从同步权限

>grant replication slave on *.* to 'test'@'%';

>flush privileges;

2：备库设置

（1）修改配置文件

vi /etc/my.cnf

[mysqld]

server-id=2

read-only=on

relay-log=slave-relay-bin

relay-log-index=slave-relay-bin.index

3：建立主从关系

（1）主

mysql> show master status;

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

| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |

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

| master-bin.000002 | 154 | | | |

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

1 row in set (0.00 sec)

（2）备

mysql>stop slave;

mysql> change master to

master_host='192.168.0.24',

master_port=3306,

master_user='test',

master_password='test',

master_log_file='master-bin.000002',

master_log_pos=154;

mysql> start slave;

4：测试

（1）主-从执行

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mysql' WITH GRANT OPTION;

FLUSH PRIVILEGES;

（2）创建数据库进行测试
