将 RebootDBInstance 与 Amazon SDK 或 CLI 配合使用

重启数据库实例

以下 reboot-db-instance 示例开始重启指定的数据库实例。

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

输出：

{
    "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...

    }
}
