Before you connect to a host in an ApsaraDB MyBase for MySQL dedicated cluster, you must create a host account. The process covers three steps: enabling the bastion host, associating the cluster host with it, and creating the account.
Prerequisites
Before you begin, ensure that you have:
The Grant OS Permissions parameter set to Enabled when the dedicated cluster was created. For more information, see Create an ApsaraDB MyBase for MySQL dedicated cluster.
A bastion host created. For more information, see Create a bastion host.
Step 1: Enable the bastion host
Log on to the Bastionhost console.
Find the bastion host and click Run on the right side. For more information, see Enable a bastion host.
Step 2: Associate the host with the bastion host
Log on to the ApsaraDB for MyBase console.
In the upper-left corner, select a region.
Find the dedicated cluster and click Details in the Actions column.
In the left-side navigation pane, click Bastion Hosts. Find the bastion host and click Associate with Bastion Host in the Actions column.
Click Import Host. In the dialog box, select the host and click Import.
Step 3: Create a host account
Find the host and click Add an account in the Host Account column.
In the Create Host Account dialog box, configure the following parameters.
