      1. API Description

      Domain name for API request: dcdb.tencentcloudapi.com.

      This API is used to create a TencentDB account. Multiple accounts can be created for one instance. Accounts with the same username but different hosts are different accounts.

      A maximum of 20 requests can be initiated per second for this API.

      We recommend you to use API Explorer
      Try it
      API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

      2. Input Parameters

      The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

      Parameter Name Required Type Description
      Action Yes String Common Params. The value used for this API: CreateAccount.
      Version Yes String Common Params. The value used for this API: 2018-04-11.
      Region No String Common Params. This parameter is not required for this API.
      InstanceId Yes String Instance ID in the format of dcdbt-ow728lmc, which can be obtained through the DescribeDCDBInstances API.
      UserName Yes String AccountName
      Host Yes String Host that can be logged in to, which is in the same format as the host of the MySQL account and supports wildcards, such as %, 10.%, and 10.20.%.
      Password Yes String Account password. It must contain 8-32 characters in all of the following four types: lowercase letters, uppercase letters, digits, and symbols (()~!@#$%^&*-+=_|{}[]:<>,.?/), and cannot start with a slash (/).
      ReadOnly No Integer Whether to create a read-only account. 0: no; 1: for the account's SQL requests, the secondary will be used first, and if it is unavailable, the primary will be used; 2: the secondary will be used first, and if it is unavailable, the operation will fail; 3: only the secondary will be read from.
      Description No String Account remarks, which can contain 0-256 letters, digits, and common symbols.
      DelayThresh No Integer If the secondary delay exceeds the set value of this parameter, the secondary will be deemed to have failed.
      It is recommended that this parameter be set to a value greater than 10. This parameter takes effect when ReadOnly is 1 or 2.
      SlaveConst No Integer Whether to specify a replica server for read-only account. Valid values: 0 (No replica server is specified, which means that the proxy will select another available replica server to keep connection with the client if the current replica server doesn’t meet the requirement). 1 (The replica server is specified, which means that the connection will be disconnected if the specified replica server doesn’t meet the requirement.)
      MaxUserConnections No Integer Maximum number of connections. If left empty or 0 is passed in, the connections will be unlimited. This parameter configuration is not supported for kernel version 10.1.
