Question

以下内容：

select * from mysql.general_log order by event_time desc

为什么会显示＆＃34;访问被拒绝＆＃34;如此频繁？似乎每隔两秒左右就会尝试这样做。这是一个错误，或者为什么会发生这种情况？这是什么意思？

当错误消息显示时，有些东西试图从您的本地计算机连接到您的服务器而不使用密码。我假设dave帐户不存在，存在但限制为IP或存在密码。

如果是复制，则不会看到'dave'@'localhost'被拒绝访问，它将是'dave'@'someotherserver'（除非您在同一服务器上运行了两个mysql进程）。

如果这是常规的事情，那么我先看cron;看看有没有经常尝试连接到MySQL。
