以下文章主要是对MySQL 复制设置的介绍 ,我们大家都知道MySQL 复制设置在实际运用中经常出现的,如果你是MySQL 复制设置这一技术的热捧着,那么下面的文章对于你而言一定很有意义。

1、停止MySQL服务

2、MySQL 复制所有文件,包括数据文件

3、master的my.ini基本不需要修改,缺省已经配置成master方式:

log-bin=MySQL-bin

binlog_format=mixed

server-id = 1

4、slave的my.ini需要修改如下:

去掉3中的master配置,添加如下内容:

server-id = 2

master-host = localhost

master-user = replication

master-password = replication

master-port = 3306

replicate-do-db=需要MySQL 复制的数据库

master-connect-retry=10

修改端口为3307等,

添加replication用户用于进行MySQL 复制。

5、重启master、slave数据库。

6、如果master设置成功,可以通过show master status;命令看到如下信息:

<ol class="dp-xml">
<li class="alt"><span><span>+------------------+----------+--------------+------------------+   </span></span></li>
<li><span>| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |   </span></li>
<li class="alt"><span>+------------------+----------+--------------+------------------+   </span></li>
<li>
<span>| </span>MySQL<span>-bin.000007 | 39259 | | |   </span>
</li>
<li class="alt"><span>+------------------+----------+--------------+------------------+   </span></li>
<li><span>1 row in set (0.00 sec)  </span></li>
</ol>
Copy after login

7、如果全部设置成功,在slave中运行show slave status;命令,可以看到相应的配置参数,说明master、slave都设置正常。

8、如果想通过CHANGE MASTER TO命令修改相应的参数,需要首先用stop slave;命令停止slave,修改成功后再运行start slave;启动slave服务。

注意:开始直接停止MySQL服务最方便,不需要进行锁表的操作。以上的相关内容就是对MySQL 复制设置的介绍,望你能有所收获。
