數(shù)據(jù)庫(kù)遷移后，連接數(shù)據(jù)庫(kù)突然報(bào)錯(cuò)：
ERROR 1286 (42000): Unknown table engine 'InnoDB'
于是查看數(shù)據(jù)庫(kù)引擎。

發(fā)現(xiàn)竟然沒有了Innodb引擎

Innodb數(shù)據(jù)庫(kù)引擎應(yīng)該是好的膝宁，應(yīng)該是日志錯(cuò)誤導(dǎo)致的驻债，于是刪掉數(shù)據(jù)庫(kù)目錄下的ib_logfile*文件(ibdata不要?jiǎng)h，千萬不要?jiǎng)h錯(cuò)了锤岸！)，然后重啟數(shù)據(jù)庫(kù)板乙，一切恢復(fù)正常是偷。
