Question

尝试使用TypeOrm连接到AWS RDS Aurora DB MySQL，这会给我Handshake inactivity timeout错误。

code: 'PROTOCOL_SEQUENCE_TIMEOUT',
fatal: true,
timeout: 10000

尝试使用默认的10秒和我自己的15秒超时。

ormconfig.json文件：

{
    "type": "mysql",
    "host": "host connection string",
    "port": 3306,
    "username": "xxxx",
    "password": "xxxx",
    "database": "xxxx",
    "synchronize": true,
    "logging": true,
    "connectTimeout": 15000,
    "entities": [
       "src/entity/**/*.ts"
    ],
    "migrations": [
       "src/migration/**/*.ts"
    ],
    "subscribers": [
       "src/subscriber/**/*.ts"
    ],
    "cli": {
       "entitiesDir": "src/entity",
       "migrationsDir": "src/migration",
       "subscribersDir": "src/subscriber"
    }
}

能够使用Linux MySQL客户端CLI连接到实例，甚至尝试在同一VPC中使用ECS连接到数据库，但出现相同的错误。

此问题最常见的过程-您的vpc和安全组规则设置错误。尝试为其编写出入规则。

使用TypeOrm和AWS RDS Aurora MySQL实例的``握手不活动超时''
