无法重新启动 MySQL Docker 容器，出现“无法打开 mysql.plugin 表”和“表 'mysql.user' 不存在”等错误

Question

服务器空间不足后，Docker MySQL 的文件似乎已损坏。

当尝试重新启动mysql:5.6容器时，我收到错误[ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.user' doesn't exist。

我无法找到损坏的文件，可能会删除它或修复权限。

这是完整的错误输出：

Answer 1

因此docker-compose rm mysql需要删除断开的连接，然后再次启动容器。
