以下的文章主要讲述的是Mysql 复制设置的实际操作步骤,如果你对Mysql 复制设置的实际操作步骤相关的实际操作有兴趣的话,你就可以对以下的文章点击观看了。以下就是相关内容的具体描述。

1、停止mysql服务

2、Mysql 复制设置mysql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:

<ol class="dp-xml">
<li class="alt"><span><span class="attribute">log-bin</span><span>=</span><span class="attribute-value">mysql</span><span>-bin   </span></span></li>
<li>
<span class="attribute">binlog_format</span><span>=</span><span class="attribute-value">mixed</span><span>   </span>
</li>
<li class="alt">
<span class="attribute">server-id</span><span> = </span><span class="attribute-value">1</span><span>  </span>
</li>
</ol>
Copy after login

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:

<ol class="dp-xml">
<li class="alt"><span><span class="attribute">server-id</span><span> = </span><span class="attribute-value">2</span><span>   </span></span></li>
<li>
<span class="attribute">master-host</span><span> = </span><span class="attribute-value">localhost</span><span>   </span>
</li>
<li class="alt">
<span class="attribute">master-user</span><span> = </span><span class="attribute-value">replication</span><span>   </span>
</li>
<li>
<span class="attribute">master-password</span><span> = </span><span class="attribute-value">replication</span><span>   </span>
</li>
<li class="alt">
<span class="attribute">master-port</span><span> = </span><span class="attribute-value">3306</span><span>  </span>
</li>
</ol>
Copy after login

replicate-do-db=需要Mysql 复制设置的数据库

<ol class="dp-xml"><li class="alt"><span><span class="attribute">master-connect-retry</span><span>=</span><span class="attribute-value">10</span><span>  </span></span></li></ol>
Copy after login

修改端口为3307等, 添加replication用户用于进行Mysql 复制设置。

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>| mysql-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。

上述的相关内容就是对Mysql 复制设置的描述,希望会给你带来一些帮助在此方面。
