Getting started with Cloud DB for Redis

Available in Classic and VPC

The Getting started with Cloud DB for Redis guide describes what you need to do to properly use Cloud DB for Redis after checking the Cloud DB for Redis use environment and supported specifications and fully understanding the overall Usage scenario and Glossary. The items described in Getting started with Cloud DB for Redis are as follows.

• How to create an application server (app server) from the NAVER Cloud Platform console.
• How to test application server connection
• How to create a Redis server from the NAVER Cloud Platform console.
• How to test Redis server connection

If you completed the above, then you've completed the basic procedure for using Cloud DB for Redis. Afterward, you have the option of proceeding with the following tasks for more efficient server management and operation.

• Event and notification settings using NAVER Cloud Platform's Cloud Insight
• Management of administration permissions using NAVER Cloud Platform's Sub Account

The above tasks can be done from Cloud Insight or Sub Account after requesting subscription, rather than in Cloud DB for PostgreSQL. They are not explained in detail in this guide. For detailed instructions, please refer to the Cloud Insight Guide, Sub Account Guide.

7. Click the [Add] button.
8. Click the [Apply] button.

Test Redis server connection

The following describes how to test if you can connect properly to the created Redis server by installing the Redis client.

1. Check the host IP address and port number information for the Redis server connection.

• Click Services > Database > Cloud DB for Redis > Redis Server menus in this order.
  • Host IP address
    • VPC: Click on service name of the Redis server to connect to and check Dns
    • Classic: Check the DNS name.
  • Port number: Check the Port.

2. Connect to the Official Redis website and check the stable version.
3. Access the application server.
4. Please download the stable version of Redis identified in Step 2

//Based on version 6.2.6 
[root@redis-web ~]# wget https://download.redis.io/releases/redis-6.2.6.tar.gz
[root@redis-web ~]# tar xvfz redis-6.2.6.tar.gz
[root@redis-web ~]# cd redis-6.2.6
[root@redis-web redis-6.2.6]# make

5. Go to the redis-6.2.6/src directory and use the information you checked in step 1 to connect to the Redis Server.

[root@redis-web redis-6.2.6]# cd src
[root@redis-web src]# ./redis-cli -h [DNS name] -p [Redis access port] -c
