Associating Instance with Security Group

Last updated: 2022-06-07 15:57:19

    A security group is an instance-level firewall provided by Tencent Cloud for controlling inbound traffic of TencentDB. You can associate a security group with a cluster when purchasing it or later in the console.
    TDSQL-C for MySQL allows you to configure different security groups for the read-write and read-only addresses respectively, which don't affect each other.

    Note:

    • A TDSQL-C for MySQL instance can be associated with up to five security groups.
    • You can configure different access addresses with different security groups, which will control only sources that access the current address.

    Prerequisites

    You have created security groups for TencentDB instances in the security group console. For more information, see Configuring Security Group.

    Associating Read-Write Address/Read-Only Address with Security Group

    1. Log in to the TDSQL-C for MySQL console and click a cluster ID in the cluster list to enter the cluster management page.
    2. On the cluster management page, select the Security Group tab and select the target address. Here:
    • Private Read-Write Address for Cluster Connection: read-write access address of the database.
    • Private Read-Only Address for Cluster Connection: read-only address of the database.
    1. Click Configure Security Group. In the pop-up window, select the target security group and click OK.
