Centos
Cent OS - MySQL 守護程序無法啟動
我正在執行具有 0.615 GB 記憶體的 AWS 微型實例。
我在其上執行 APC，預設最大為 35 MB。
現在我重新啟動了mysqld，它不會啟動。它剛剛停止。我現在真的需要啟動並執行它。它對我來說非常緊迫。
以下是日誌，請分享您的經驗，以最快的速度解決此問題。
提前致謝，

這是日誌的重要部分：
140116 3:15:59 InnoDB: Initializing buffer pool, size = 128.0M InnoDB: mmap(137363456 bytes) failed; errno 12 140116 3:15:59 InnoDB: Completed initialization of buffer pool 140116 3:15:59 InnoDB: Fatal error: cannot allocate memory for the buffer pool（Errno 12 是“無法分配記憶體”）
所以我們看到 MySQL 嘗試分配 128 MB 並沒有這樣做。這意味著您的實例沒有足夠的記憶體。
可能是您正在執行某些正在洩漏記憶體的東西，並且重新啟動實例將使您啟動並執行。
但更有可能的是，您需要遍歷所有程序並查看記憶體佔用情況，並適當調整它們以在微實例中執行，或升級實例大小。
