Getting started

Available in Classic

Getting started with Cloud DB for Cache describes what you need to do to properly use Cloud DB for Cache after checking the Cloud DB for Cache user environment and supported specifications and fully understanding the quickstart and glossary The following is the content dealt with in getting started with Cloud DB for Cache:

• How to create an application server (App server) in the NAVER Cloud Platform console.
• How to test application server connection.
• How to create a DB Server in the NAVER Cloud Platform console.
• How to test access to the DB Server.

If you complete the above, then you've completed the basic procedure for using Cloud DB for Cache. Afterward, you can perform the following tasks for more efficient server management and operation:

• Event and notification (alarm) settings using NAVER Cloud Platform's Cloud Insight.
• Permissions management for using NAVER Cloud Platform's Sub Account.

The above tasks can be done from Cloud Insight or Sub Account after subscribing, rather than in Cloud DB for Cache, which are not explained in detail in this guide. Learn more in the Cloud Insight user guide and Sub Account user guide.

Create an application server

To create an application server from the NAVER Cloud Platform console:

1. In the Classic environment of the NAVER Cloud Platform console, navigate to Menu > All services > Compute > Server.
2. Click [Create server].
3. Select the server image and click [Next].
4. Enter the required information and click [Next].
5. If you do not have an existing authentication key, then create a new authentication key and click [Next].
6. If you do not have any ACG, create a new one.
7. For a simple setup, set the access range to 0.0.0.0/0 to allow access from all locations.
8. After the final confirmation, click [Create server].

Configure the connection environment

From NAVER Cloud Platform console, you can set up the access environment for application servers by using port forwarding and a public IP, or SSL and VPN.

Configure port forwarding

To configure port forwarding:

1. In the Classic environment of the NAVER Cloud Platform console, navigate to Menu > All services > Compute > Server.
2. Click the server you want to set up port forwarding, and then click [Set port forwarding].
3. Enter the port number you want to access from the outside, and then click [Add].
4. Click [Apply].

Set public IP

To set up a public IP:

1. In the Classic environment of the NAVER Cloud Platform console, navigate to Menu > All services > Compute > Server.
2. Click Public IP.
3. Click [Request public IP].
4. Select the target server, enter a memo, and click [Next].
5. Click [Create].

Check admin password

To get the admin (root) password required for accessing the application server after setting up the port forwarding or the public IP, follow these steps:

1. 1. In the Classic environment of the NAVER Cloud Platform console, navigate to Menu > All services > Compute > Server.
2. Click [Server management and settings] and click the Check Administrator Password menu.
3. Enter the authentication key generated while creating the server.
4. Click [Check password].
5. Check the password.

Set SSL VPN

To allow external access to the DB Server to be created by using SSL VPN, follow these steps:

1. Create SSL VPN
2. Set the DB Server's ACG
3. Check the access information of the DB Server

1. Create SSL VPN

To create an SSL VPN:

1. In the Classic environment of the NAVER Cloud Platform console, navigate to Menu > All services > Security > SSL VPN.
2. Click [Request for an SSL VPN].
3. When the Create SSL VPN popup appears, enter the required information, and then click [Create].
4. After creation, check the SSL VPN IP address range from the delivered email or the SSL VPN interface of the console.

2. Set the DB Server's ACG

To set up a DB Server's ACG, follow these steps:

1. In the Classic environment of the NAVER Cloud Platform console, navigate to Menu > All services > Database > Cloud DB for Cache.
2. Click the DB Server menu.
3. From the details interface of the server to be configured, click of the ACG.
4. Click [Set ACG].
5. Add settings to allow SSL VPN access.
   • Access source: IP address range of the SSL VPN
   • Allowed port: DB Server port.
6. Click [Apply].

3. Check the access information of the DB Server

After completing the external access settings using SSL VPN, check the access information of the DB Server. To view the information:

1. In the Classic environment of the NAVER Cloud Platform console, navigate to Menu > All services > Database > Cloud DB for Cache.
2. Click the DB Server menu.
3. Click to select the server you want to check, and check the necessary information from the view details interface.
   • DNS name: Used similarly to DB server host name
   • DB access port

Test the application server connection

To test connectivity to the application server using the PuTTY terminal program:

1. Run PuTTY.
2. In Host Name (or IP address) enter the public IP or the IP address obtained through port forwarding, and in Port, enter the port number obtained through the public IP or port forwarding configuration.
   
3. Click [Open].
4. When the PuTTY security alert popup appears, click [Yes].
   
5. When the cmd window for server access appears, enter the password you got from get admin password.
   

Create DB Server

Some of the services provided by NAVER Cloud Platform require you to go through the subscription procedure from the console before the start of actual usage. However, for Cloud DB for Cache, you can start using it upon creation of a DB Server without a separate subscription step. To create a DB Server in the NAVER Cloud Platform console:

1. In the Classic environment of the NAVER Cloud Platform console, navigate to Menu > All services > Database > Cloud DB for Cache.
2. Click the DB Server menu.
3. Click [Create DB Server].
4. When the subscribe interface appears, enter the required information and click [Next].
5. Click [Create].

ACG settings

To set up Access Control Group (ACG) for DB servers from NAVER Cloud Platform console:

1. In the Classic environment of the NAVER Cloud Platform console, navigate to Menu > All services > Database > Cloud DB for Cache.
2. Click the ACG menu.
   
3. Click and select the ACG to set up, and then click [Set ACG].
   • Select the automatically created DB Server ACG.
4. Enter the ACG name of the application server in Access source.
5. Enter the port number in Allowed port.
6. Click [Add].
7. Click [Apply].

Test DB Server connection

To test if you can connect properly to the created DB server by installing the DB client:

1. Check the host IP address and port number required to connect to the DB server.

• Click Menu > All services > Database > Cloud DB for Cache > DB Server.
  • Host IP address: Click the Service name of the DB server you want to connect to and check the DNS name.
  • Port number: Click the Service name of the DB server you want to connect to and check the Access port.

2. Go to the Official Redis website and check the Stable version.
3. Access the application server.
4. Download the stable version of Redis confirmed 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 access the Redis Server using the information confirmed in step 1.

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