<span style="font-size:18px;">简单步骤总结--快速实现: 一:主服务器的配置步骤: 2:给从服务器设置授权用户 grant all on *.* to user1@192.168.10.2 identified by "pass123"; (all表示所有权限的意思,授权所有的用户,关于数据库所有的表(只能是这台服务器192.168.10.2,如果主机是字符串单引号扩着'leyangjunpc'):账号是user1 密码是pass123) GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO repl@'192.168.0.%' IDENTIFIED BY 'p4ssword'; 3:修改主数据库服务器的配置文件my.cnf/ini,开启bin-log日志,并设置server-id的值 log-bin=mysql-bin server-id=1 (主从server-id一定要保证唯一,不能相同) --一主多从也一样 二:从服务器的配置步骤: 1:配置文件中:修改数据库的server-id,注意server-id的值必须是唯一的,不能和主数据的配置相同,如果有多个 从服务器,每个从服务器必须有自己唯一的server-id值 开启bin-log 2:Mysql版本从5.1.7以后开始就不支持“master-host”类似的参数 在从库上执行如下命令; change master to master_host='masterIP', master_user='slave', master_password='slvaePASS'; slave start;重启 3:配置完后->检测是否和主服务器同步方法(数据同步成功不成功就看*): show slave status\G 看到:* Salve_IO_Running :Yes (表示成功的把主服务器的bin-log日志拿回来了且同步,写一行我就同步一行) * Salve_SQL_Running :Yes (拿过来的bin-log日志并成功的执行了sql语句,一主数据一致) --看到为yes的说明已经和主服务器取得同步 master_Log_File:mysql-bin.00002 (同步过来的bin-log日志) Read_Master_Log_Pos:106 (位置,show master status主看下就知道) Connect_Retry:60 (每隔60秒回去主服务器同步bin-log日志) 踪迹日志: Relay-Log_File:localhost-relay-bin.00004 (从服务器生成的日志文件,不叫mysql-bin.xxx) 数据同步过来后,我们查询数据就可以去从服务器上查询不用去主服务器,减轻负载 能后你就可以尽情的玩你的主从复制啦,注意别在从服务器上乱删数据哦,要不能主从同步会有问题的,就够你玩的啦 </span>
