   <td style="border-color:rgb(204,204,204);font-size:1em;line-height:1.1em;width:614.4px;background:none;vertical-align:baseline;font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;min-height:auto;"> 
    <div style="line-height:15.4px;background:none;border:0px;vertical-align:baseline;min-height:auto;"> 
     <div style="line-height:15.4px;background-image:none;border:0px;vertical-align:baseline;min-height:auto;"> 
      <code style="background:rgb(255,255,255);border-width:0px 0px 0px 3px;border-left-style:solid;border-left-color:rgb(108,226,108);width:640px;font-size:14px;clear:both;vertical-align:baseline;font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;min-height:auto;color:rgb(0,0,0);">rpm -qa|</code>

可以看到如下图的所示：

显示之前安装了：

MySQL-client-5.5.25a-1.rhel5

MySQL-server-5.5.25a-1.rhel5

2、停止mysql服务、删除之前安装的mysql

删除命令：`rpm -e –nodeps 包名`

具体的步骤如图：查找目录并删除
