Mysql已经离开了媒体寺庙

真的想要一些帮助。

上传大文件75mb时，我不断收到错误Mysql已经消失了。任何低于20mb的东西上传都很好。

所以我在这里的其他帖子上调查了这个错误。我在媒体寺庙，但他们不幸地说它超出了他们的范围。

我在/etc/my.cnf

编辑了这个文件my.cnf 
[client]

所以我把等待超时部分加到600这应该绰绰有余？

我的php.ini文件设置如下。

请增加wait_timeout

的时间
  

可能有两个原因： -

     
      
  1. 服务器超时并关闭连接。如何解决：检查一下   mysqld的my.cnf / my.ini配置中的 wait_timeout 变量   文件足够大。
    2.   
  2. 服务器丢弃了错误或过大的数据包。如果mysqld得到了   数据包太大或不正确，它假设有东西   客户端出错并关闭连接。您可以   通过增加值来增加最大数据包大小限制   my.cnf / my.ini文件中的 max_allowed_pa​​cket 。
    3.
