select * from mysql.general_log order by event_time desc

它爲什麼會出現「拒絕訪問」如此頻繁？似乎它每兩秒鐘就會嘗試這樣做。這是一個錯誤還是爲什麼發生這種情況，這是什麼意思？

哪些進程已經打開MySQL sock進行寫入？（'fuser'或'lsof'可以顯示你。） – sarnold

'mysqld 15806 _mysql 21u IPv4 0xffffff600c106a40 0t0 TCP *：mysql（LISTEN）' – David542

您有沒有嘗試過，或許後來放棄了設置複製？ –

由於錯誤消息顯示，有人試圖從本地計算機以dave連接到服務器，而無需使用密碼。我假設戴夫帳戶不存在，存在但限制爲IP或存在密碼。

如果是複製，你不會看到'dave'@'localhost'被拒絕訪問，它會是'dave'@'someotherserver'（除非你有兩個mysql進程在同一臺服務器上運行）。

如果是普通的事情，那我先看看cron;看看有沒有什麼經常試圖連接到MySQL。
