Connecting to an Instance Using a Private IP Address
You can use the private IP address to connect to the GeminiDB Redis instance.
This section uses the Linux OS as an example to describe how to connect to a GeminiDB Redis instance using the Redis-cli client. This section describes how to connect to a GeminiDB Redis instance in non-SSL mode.
Precautions
- The target instance must be in the same VPC and subnet as the ECS.
- The ECS must be in a security group that has access to the instances. For details, see Configuring Security Group Rules for Nodes.
- To connect to a DB instance over a non-SSL connection, SSL must be disabled. For details about how to disable SSL, see Configuring an SSL Connection.
Prerequisites
An ECS has been created. The following uses a Linux ECS as an example. For details, see Purchasing an ECS in Getting Started with Elastic Cloud Server.
Procedure
- Log in to the ECS. For details, see Logging In to an ECS in Getting Started with Elastic Cloud Server.
- Obtain the Redis client.
Method 1
Run the following command to download the Redis client.
wget http://download.redis.io/releases/redis-6.2.0.tar.gz
Method 2
Download the Redis client and upload it to the ECS.
- Decompress the client tool package.
tar -xzf redis-6.2.0.tar.gz
- Connect to the DB instance in the src directory.
cd redis-6.2.0 make cd src ./redis-cli -h <DB_HOST> -p <DB_PORT> -a <DB_PWD>
Example:
./redis-cli -h 192.xx.xx.xx -p 8635 -a <DB_PWD>
Table 1 Parameter description Parameter
Description
<DB_HOST>
The private IP address of the instance to be connected.
To obtain this IP address, go to the Instance Management page and click the target DB instance name. The IP address can be found in the Private IP Address field under Node Information on the Basic Information page.
If the instance you purchased has multiple nodes, select the private IP address of any node.
<DB_PORT>
Port for accessing the target instance. Configure this parameter based on service requirements.
To obtain the instance port number, perform the following steps:
Click the target instance to go to the Basic Information page. In the Network Information area, you can find the database port.
<DB_PWD>
Administrator password set when you buy a GeminiDB Redis instance
- Check the results. If the following information is displayed, the connection is successful.
