RebootDBInstance 搭配 AWS SDK或 使用 CLI

若要重新啟動資料庫執行個體

下列reboot-db-instance範例會啟動指定資料庫執行個體的重新啟動。

aws rds reboot-db-instance \
    --db-instance-identifier test-mysql-instance

輸出：

{
    "DBInstance": {
        "DBInstanceIdentifier": "test-mysql-instance",
        "DBInstanceClass": "db.t3.micro",
        "Engine": "mysql",
        "DBInstanceStatus": "rebooting",
        "MasterUsername": "admin",
        "Endpoint": {
            "Address": "test-mysql-instance.############.us-west-2.rds.amazonaws.com",
            "Port": 3306,
            "HostedZoneId": "Z1PVIF0EXAMPLE"
        },

    ... output omitted...

    }
}
