我按照此处提供的修复程序进行了操作：
http://dev.mysql.com/doc/mysql-windows-excerpt/5.0/en/resetting-permissions-windows.html
但它对我不起作用。那是为什么？
答案 0 :(得分：0)
它只是一个猜测，但错误日志中的这些行让我觉得你的PC上运行了另一个MySQL服务器，它已经抓住了3306端口。
[ERROR] Can't start server: Bind on TCP/IP port: No such file or directory
[ERROR] Do you already have another mysqld server running on port: 3306 ?
查看服务管理单元
windows key + R
Keyin services.msc
Press OK button
如果您安装了64位WAMPServer，则WAMPServer的MySQL Server实例称为wampmysqld或wampmysqld64。
如果另一个MySQL实例正在运行，它可能被称为MYSQL。如果您看到其中一个已运行MySQL服务器。
找出原因。
如果您不再需要其他实例，请将其卸载。
请记住备份您认为可能仍需要移动到WAMPServer的MySQL服务器的任何数据库。
你的PC上一定只需要一个MySQL。
或者，您可以将MYSQL服务的Startup Type更改为已禁用。然后，如果您以后发现需要它，可以返回并重新启用它。
禁用其他服务将允许WAMPServer的MySQL启动。
