Connecting to a DB Instance from a Windows ECS

Step 1: Buy an ECS

1. Log in to the management console and check whether there is an ECS available.
   • If there is a Linux ECS, see Connecting to a DB Instance from a Linux ECS.
   • If there is a Windows ECS, go to 3.
   • If no ECS is available, go to 2.
   Figure 1 ECS
   
2. Buy an ECS and select Windows as its OS.

   To download a MySQL client to the ECS, bind an EIP to the ECS. The ECS must be in the same region, VPC, and security group as the RDS for MySQL DB instance for mutual communications.

   For details about how to purchase a Windows ECS, see "Purchasing an ECS" in Elastic Cloud Server Getting Started.

3. On the ECS Information page, view the region and VPC of the ECS.
   Figure 2 ECS information
   

4. On the Basic Information page of the RDS for MySQL instance, view the region and VPC of the DB instance.
   Figure 3 DB instance information
   
5. Check whether the ECS and RDS for MySQL instance are in the same region and VPC.
   • If yes, go to Step 2: Test Connectivity and Install MySQL-Front.
   • If they are not in the same region, purchase another ECS or DB instance. The ECS and DB instance in different regions cannot communicate with each other. To reduce network latency, deploy your DB instance in the region nearest to your workloads.
   • If the ECS and DB instance are in different VPCs, change the VPC of the ECS to that of the DB instance. For details, see Changing a VPC.

Step 2: Test Connectivity and Install MySQL-Front

1. Log in to the ECS. For details, see Login Using VNC in the Elastic Cloud Server User Guide.
2. On the Instances page, click the DB instance name.
3. Choose Connectivity & Security from the navigation pane. In the Connection Information area, obtain the floating IP address and database port of the DB instance.
   Figure 4 Connection information
   
4. Open the cmd window on the ECS and check whether the floating IP address and database port of the DB instance can be connected.

   telnet 192.168.6.144 3306

   • If yes, network connectivity is available.
   • 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 an outbound rule for the floating IP address and port of the DB instance.
       Figure 5 ECS security group
       
     • If in the security group of the DB instance, there is no inbound rule allowing the access from the private IP address and port of the ECS, add an inbound rule for the private IP address and port of the ECS. For details, see Configuring Security Group Rules.
5. Open a browser, and download and install the MySQL-Front tool on the ECS (version 5.4 is used as an example).

Step 3: Connect to the DB Instance Using MySQL-Front

1. Start MySQL-Front.
2. In the displayed dialog box, click New.
   Figure 6 Connection management
   
3. Enter the information of the DB instance to be connected and click Ok.

   Table 1 Parameter description

   Parameter	Description
   Name	Name of the database connection task. If you do not specify this parameter, it will be the same as that configured for Host by default.
   Host	Floating IP address obtained in 3.
   Port	Database port obtained in 3. The default value is 3306.
   User	Name of the user who will access the DB instance. The default user is root.
   Password	Password of the account for accessing the DB instance.

4. In the displayed window, select the connection that you have created in 3 and click Open. If the connection information is correct, the DB instance will be connected.
