![SHOW ENGINES;不列出 InnoDB](https://linux22.com/image/531651/SHOW%20ENGINES%EF%BC%9B%E4%B8%8D%E5%88%97%E5%87%BA%20InnoDB.png)
从昨天开始,我在 Ubuntu 上安装的 Mysql 中的 InnoDB 表不再起作用,我尝试使用 Navicat 打开它们,但出现“未知表引擎‘InnoDB’”错误。
当我尝试列出所有使用Show Engines;
它的引擎时返回;
+------------+---------+----------------------------------------------------------------+--------------+------+------------+
| Engine | Support | Comment | Transactions | XA | Savepoints |
+------------+---------+----------------------------------------------------------------+--------------+------+------------+
| MyISAM | DEFAULT | Default engine as of MySQL 3.23 with great performance | NO | NO | NO |
| MRG_MYISAM | YES | Collection of identical MyISAM tables | NO | NO | NO |
| BLACKHOLE | YES | /dev/null storage engine (anything you write to it disappears) | NO | NO | NO |
| CSV | YES | CSV storage engine | NO | NO | NO |
| MEMORY | YES | Hash based, stored in memory, useful for temporary tables | NO | NO | NO |
| FEDERATED | NO | Federated MySQL storage engine | NULL | NULL | NULL |
| ARCHIVE | YES | Archive storage engine | NO | NO | NO |

如您所见,InnoDB 未列出,有什么建议可以解决此问题吗?或者甚至可以更改表的引擎,而不需要旧引擎?
检查日志后,我发现了这一点;
/usr/sbin/mysqld: Can't create/write to file '/tmp/ibnGBtbE' (Errcode: 13)
101129 21:03:17 InnoDB: Error: unable to create temporary file; errno: 13
101129 21:03:17 [ERROR] Plugin 'InnoDB' init function returned error.
101129 21:03:17 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
知道如何解决这个问题吗?
答案1
那么听起来 /tmp 上的权限就乱了。
chmod 1777 /tmp
然后尝试重启mysql
答案2
检查您的 mysql 错误日志..您可能对 my.cnf 文件进行了更改,并且由于 ibdata 文件大小不正确导致 innodb 无法初始化。
