Question

我正在尝试创建一个新的AWS胶合连接。我正在使用下面的boto3脚本。我可以连接类似的脚本并检索数据目录数据库中表的结构。所以我知道客户在工作。我知道可用区也是us-west-2。我从已经创建的粘合连接中复制了其余信息。我只是尝试测试boto3脚本，以查看是否可以通过该脚本创建连接。有人知道这个问题可能是什么吗？我正在尝试连接到ec2实例上的mysql数据库。

代码：

# create new connection

response = client.create_connection(
    ConnectionInput={
        'Name': 'tst_scrpt',
        'ConnectionType': 'JDBC',
        'MatchCriteria': [
            'string',
        ],
        'ConnectionProperties': {
            'string': 'jdbc:mysql://xxxxx:3306/disxxx',
            'username':'root',
            'password':'ipxxxxx'
        },
        'PhysicalConnectionRequirements': {
            'SubnetId': 'subnet-04xxxxx',
            'SecurityGroupIdList': [
                'sg-xxxxx'
            ],
            'AvailabilityZone': 'us-west-2'
        }
    }
)

错误：

Boto3定义的create_connection Glue API没有提及要为“ ConnectionProperties”字段传递哪些参数。它只提到要提供键值对。要传递的值如下。


client = boto3.client('glue', region_name='<region-to-use>')

response = client.create_connection(
    CatalogId='<account-id>',
    ConnectionInput={
        'Name': '<name-of-the-connection>',
        'Description': 'Test connection',
        'ConnectionType':'JDBC',
        'ConnectionProperties': {
            'USERNAME': '<db-username>',
            'JDBC_ENFORCE_SSL': 'false',
            'PASSWORD': '<db-password>',
            'JDBC_CONNECTION_URL': 'jdbc:protocol://host:port/db_name'
        },
        
        'PhysicalConnectionRequirements': {
            'SubnetId': '<subnet-to-use>', 
            'AvailabilityZone': '<availability-zone-to-use>', 
            'SecurityGroupIdList': ['<security-group(s)-to-use>']
    }
    }
)

Answer 2

我的ConnectionProperties错误。将“字符串”替换为“ JDBC_CONNECTION_URL”。更正如下。

 'ConnectionProperties': {
                'JDBC_CONNECTION_URL': 'jdbc:mysql://dataxxx:3306/disxxx',
                'username':'root',
                'password':'ip1k5PNCxxxxx'
            }

使用boto3创建与mysql的粘合连接
