<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
如果数据量不大，可以直接在DedeCMS后台使用数据表修复的功能，这个是比较容易方便的。<br>
或者可以借助第三方的MySQL管理工具，例如PHPMyadmin或者HeidiSQL</p>

(1) <strong>myisamchk</strong></p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
使用myisamchk必须暂时停止MySQL 服务器。例如，我们要检修blog数据库。执行以下操作：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>

<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>

<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode2" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
# service mysql stop (停止MySQL)<br>
# myisamchk -r /datawhere/blog/*MYI<br>
# service mysql start myisamchk 会自动检查并修复数据表中的索引错误。</div>

(2)<strong> mysqlcheck</strong></p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
使用mysqlcheck无需停止MySQL，可以进行热修复。操作步骤如下：(检修 blog库)</p>

<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode3" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
# mysqlcheck -r -uroot -p blog</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
注意，无论是 myisamchk还是mysqlcheck，一般情况下不要使用-f强制修复，-f参数会在遇到一般修复无法成功的时候删除</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
部分出错数据以尝试修复。所以，不到万不得已不要使用-f。</p>
