Connecting to a DB Instance Through MySQL-Front

You can bind an EIP to a DB instance for public access and unbind it as required.

If an EIP has been bound to the DB instance, skip this step.

1. Log in to the management console.
2. Click in the upper left corner and select a region and project.
3. Click in the upper left corner of the page, choose Databases > TaurusDB.
4. On the Instances page, click the instance name to go to the Basic Information page.
5. In the Network Information area, click Bind under Public IP Address (EIP).
6. In the displayed dialog box, select an EIP and click OK.
   If no EIPs are available, click View EIP to create an EIP on the network console. After the EIP is created, go back to the Basic Information page and bind the newly created EIP to the instance.

   

   You need to configure security group rules and enable specific IP addresses and ports to access the DB instance. For details, see Configuring Security Group Rules.

7. In the Network Information area, locate Public IP Address (EIP) and view the bound EIP.

1. Log in to the management console.
2. Click in the upper left corner and select a region and project.
3. Click in the upper left corner of the page, choose Databases > TaurusDB.
4. On the Instances page, click the instance name to go to the Basic Information page.
5. In the Network Information area, obtain the EIP and database port.

1. Open the cmd window on your local server and check whether the EIP and database port of the DB instance can be connected.

   telnet EIP port

   Example:

   telnet 192.168.0.16 3306

   

   If the message "command not found" is displayed, install the Telnet tool based on the OS used by the ECS.

   • If yes, network connectivity is normal.
   • If no, check the security group rules.
     • If in the security group of the ECS, there is no outbound rule with Destination set to 0.0.0.0/0 and Protocol & Port set to All, add the EIP and port of the DB instance to the outbound rules.

     • If in the security group of the DB instance, there is no inbound rule allowing the access from the EIP and port of the ECS, add the EIP and port of the ECS to the inbound rules. For details, see Configuring Security Group Rules.

2. Open a browser, and download and install the MySQL-Front tool locally (version 5.4 is used as an example).

1. Start MySQL-Front.
2. In the displayed dialog box, click New.
