"Icinga Mysql migration error: missing table in engine"

Question

我尝试将icinga更新到2.9.1版本，并且为此需要在sql数据库上应用迁移。

迁移使用以下sql查询：

2.9.0迁移

CREATE TABLE `icingaweb_rememberme`(
    ->   id                int(10) unsigned NOT NULL AUTO_INCREMENT,
    ->   username          varchar(254) COLLATE utf8mb4_unicode_ci NOT NULL,
    ->   passphrase        varchar(256) NOT NULL,
    ->   random_iv         varchar(24) NOT NULL,
    ->   http_user_agent   text NOT NULL,
    ->   expires_at        timestamp NULL DEFAULT NULL,
    ->   ctime             timestamp NULL DEFAULT NULL,
    ->   mtime             timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP,
    ->   PRIMARY KEY (id)
    -> ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin;

2.9.1迁移

ALTER TABLE `icingaweb_rememberme`
    ->     MODIFY random_iv varchar(32)  NOT NULL;

问题是，当我尝试执行时，我得到了冲突的错误消息

完整的迁移日志

MariaDB [(none)]> use icingaweb2

MariaDB [icingaweb2]> CREATE TABLE `icingaweb_rememberme`(
    ->   id                int(10) unsigned NOT NULL AUTO_INCREMENT,
    ->   username          varchar(254) COLLATE utf8mb4_unicode_ci NOT NULL,
    ->   passphrase        varchar(256) NOT NULL,
    ->   random_iv         varchar(24) NOT NULL,
    ->   http_user_agent   text NOT NULL,
    ->   expires_at        timestamp NULL DEFAULT NULL,
    ->   ctime             timestamp NULL DEFAULT NULL,
    ->   mtime             timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP,
    ->   PRIMARY KEY (id)
    -> ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin;
ERROR 1050 (42S01): 表'icingaweb_rememberme'已经存在
MariaDB [icingaweb2]> ALTER TABLE `icingaweb_rememberme`
    ->     MODIFY random_iv varchar(32)  NOT NULL;
ERROR 1932 (42S02): 表'icingaweb2.icingaweb_rememberme'在引擎中不存在

Icinga当前显示此错误（类似于第二个迁移错误）

SQLSTATE[42S02]: 基表或视图不存在：1932 表'icingaweb2.icingaweb_rememberme'在引擎中不存在

问题

我如何应用迁移，以便集合icingaweb2具有表icingaweb_rememberme

Answer 1

I found the anwser.

MySQL database created a file named icingaweb_rememberme.idb, but there is no corresponding frm file.

I have deleted the icingaweb_rememberme table, removed the remaining .idb files in the MySQL directory, and re-created the table with a single command (having applied the secondary migration).

This may not be the complete answer, or there may be a simpler solution, but for me this worked.

If you plan to delete or remove files and tables, remember to back them up
