亞馬遜EC2 MySQL無法啓動

我在幾分鐘前隨機停止工作後開始啓動MySQL時遇到問題。在試圖連接我得到這個錯誤：亞馬遜EC2 MySQL無法啓動

Connect failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

於是，我就重啓MySQL（這不得不之前爲我工作），我得到這個：

Stopping mysqld:           [ OK ] 
MySQL Daemon failed to start. 
Starting mysqld:           [FAILED]

這裏是我的錯誤日誌：

任何人都可以提供一些提示嗎？我很不喜歡這個服務器的東西：P

非常感謝！

日誌條目似乎從4月14日初次初始化時開始。這是整個日誌嗎？還要確保你沒有用'df'檢查磁盤空間不足。 – datasage

我通過重新啓動EC2實例解決了這個問題。

+1非常感謝你@goddfree我有一個類似的問題，讓我回來了幾個小時 - 看到我的問題在這裏：http://wordpress.stackexchange.com/questions/110746/error-establishing-a-database-connection- mysql-error-2002-aws-ec2-outage – Anthony

我很高興這有助於別人。我深入探究了這個問題，並被告知實質上MySQL數據庫崩潰了，因爲我使用的EC2實例沒有足夠的處理能力來處理我正在執行的查詢。 – Charles

謝謝，我有同樣的問題，我重新啓動ec2實例，但由於某種原因，MySQL服務器本身並沒有啓動，奇怪，我不得不手動啓動它，它解決了我的問題...感謝分享這個答案，我從來沒有想過重新啓動ec2實例:)最好的問候。 –
