Changing a Database Port

Scenarios

After Babelfish is enabled, TaurusDB for PostgreSQL listens on two ports. The default port of a PostgreSQL database is 5432, and that of a Babelfish database is 1433.

This section describes how to change the database port of a primary DB instance. For primary/standby DB instances, changing the database port of the primary DB instance will cause the database port of the standby DB instance to also be changed.

If specific security group rules have been configured for a DB instance, you need to change the inbound rules of the security group to which the DB instance belongs after changing the database port.

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select a region.
3. Click in the upper left corner of the page and choose Databases > TaurusDB.
4. On the Instances page, click the primary instance name.
5. On the Basic Information page, find Database Port and click Configure under it.

   TaurusDB for PostgreSQL instances can use database ports 1433 and 2100 to 9500.

6. In the displayed dialog box, enter a new port and click OK.
   • Changing the primary DB instance's port updates the standby DB instance's port as well and causes both of them to reboot.
   • This process takes 1 to 5 minutes.

7. If you have enabled operation protection, click Send Code in the displayed Identity Verification dialog box and enter the obtained verification code. Then, click OK.

   Two-factor authentication improves the security of your account and cloud product. For details about how to enable operation protection, see the Identity and Access Management User Guide.
