网站(MYSQL)出现以下三种情况的真正原因是MCAFEE引起的

1, 您的服务器环境不允许执行数据库校验，无法进行此操作。

真正原因如下:

1, C:/WINDOWS/TEMP文件夹权限不够,至少也要给出USERS组的可读可写权限; (给出权限)

2, C:/WINDOWS/TEMP文件夹的磁盘满了,文件写不进去了;(清空TEMP文件夹)

3, 你的服务器装了MCAFEE杀毒软件,它的访问保护禁止了TEMP文件可写;(修改访问保护设置)

4, 还是MCAFEE杀毒软件的问题,解决步骤:按访问扫描属性-所有进程-检测项-扫描文件(在写入磁盘时)勾去掉,OK.

5, C:/WINDOWS/TEMP 清空这个文件夹 或是删除 #sql_5ac_0.MYD'

说明:

1, 有很多人说是1,2条的问题.难道大家这个都不知道吗?笑话!

2, 有很多人说删#sql_5ac_0.MYD' 这个文件就可以了,是啊.没错,当时是可以了.当你操作数据库后又会出现此问题,难道不是吗?所以删除#sql_5ac_0.MYD' 文件后根本没解决真正的问题,但这个文件还是要删除!

3, 最终由本人一个晚上未睡觉,多次测试,找到了最终的原因就是第4条,MCAFEE杀毒软件的问题.


4, 如果你没装MCAFEE,你就检查别的杀毒软件或前面说过的设置!
