replication with binary log file

Master端： A、 在my.cnf中开启二进制日志、设置server-id（需要唯一），然后保存重启mysqld服务。

log-bin=mysql-bin
server-id=1

B、 创建主从复制所需的账号

CREATE USER 'repl'@'%' IDENTIFIED BY '123qweASD!@#';
GRANT REPLICATION SLAVE ON *.* TO 'repl'@'%';

C、 show master status查看File和Position

show master status;

SLAVE端：

A、 在my.cnf中设置server-id，保存重启。 server_id=2 B、 设置主服务器配置。

CHANGE MASTER TO
    -> MASTER_HOST='192.168.1.121',
    -> MASTER_USER='repl',
    -> MASTER_PASSWORD='123qweASD!@#',
    -> MASTER_LOG_FILE='master1-bin.000001',
    -> MASTER_LOG_POS=245;

C、 开启slave线程 start slave; 通过show slave status\G;查看同步状态。

mysql> show slave status\G;
