Mysql
Tokudb 錯誤和外掛失去導致 mysql 停止啟動？
我實際上已經安裝了 percona mysql 並試圖從 oracle mysql 遷移。我使用 innodb 已經有一段時間了。我聽到並閱讀了很多關於 tokudb 能夠支持大型數據庫等的資訊。所以我確實嘗試過嘗試。今天突然執行正常了，我執行 yum update 它停止了工作。
下面是我的mysqld.cnf
# Percona Server template configuration [mysqld] # # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid #default-storage-engine=tokudb最初，我在更新後將 tokudb 作為我的預設儲存，一切都搞砸了，我在 #default-storage-engine=tokudb 註釋了這一行，然後我的 mysql 才啟動。
這是我執行 yum 更新時更新的樣子。

我推薦你
- 保持
default-storage-engine=tokudb註釋掉ENGINE=tokudb僅在將從中受益的表上手動指定- 為其他表保留 InnoDB
- 送出錯誤報告
對於特定查詢
使用 InnoDB（可能還有 TokuDB）：
在一次或一個時間範圍內選擇關於一輛車的內容（無論表中的內容）：
INDEX(vehicle_id, datetime)為特定車隊中的特定車輛選擇東西（假設上述內容還不夠）：
INDEX(vehicle_id, fleet_id, datetime) -- or -- INDEX(fleet_id, vehicle_id, datetime)
