Ubuntu
無法啟動生產 mysql 伺服器。也沒有日誌消息
這是我們為客戶管理的生產實例 (EC2)。停機時間已經5小時。我完蛋了。
故事
今天早上我發現我們的一個客戶 mysqld 程序處於終止狀態。我做到
sudo service mysql start
了,並讓它執行起來。日誌告知這是由於表崩潰而發生的。在瀏覽了網際網路上的一些參考資料後,我執行了以下命令:
# mysqld was running $ mysqlrepair -A --auto-repair $ mysqlrepair -A -o # By the time the following command was executed, mysqld had stopped $ mysqlrepair -A -c
於是乎,以下命令拒絕啟動mysqld
$ sudo service mysql start start: Job failed to start $ sudo mysqld --verbose $ ps aux | grep mysql ubuntu 24124 0.0 0.1 8108 936 pts/0 S+ 04:07 0:00 grep --color=auto mysql $ sudo mysqld_safe 131130 04:09:02 mysqld_safe Logging to '/var/log/mysql/error.log'. 131130 04:09:02 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 131130 04:09:02 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
/var/log/mysql/error.log 中沒有目前時間戳。

通過添加到 my.cnf 解決了問題:
innodb_buffer_pool_size = 16M
