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) from NAVER Cloud Platform console
• How to test application server connection
• How to create DB servers from NAVER Cloud Platform console
• How to test DB server connection

If you complete the above, then you've completed the basic procedure for using Cloud DB for Cache. Afterward, you have the option of proceeding with 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. For more information, see Cloud Insight user guides and Sub Account user guides.

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. In the Classic environment of the NAVER Cloud Platform console, navigate to > Services > Compute > Server.
2. Click [Manage servers and change settings], and then click the Check admin 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 ACG of DB Server
3. Check access information of DB Server

1. Create SSL VPN

To create an SSL VPN, follow these steps:

1. In the Classic environment of the NAVER Cloud Platform console, navigate to > Services > Compute > Server.
2. Click [Request for an SSL VPN].
3. When the Create SSL VPN popup window 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 page of the console.

2. Set ACG of DB Server

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

1. In the Classic environment of the NAVER Cloud Platform console, navigate to > Services > Compute > Server.
2. Click the DB Server menu.
3. From the details page of the server to be configured, click the button of the ACG.
4. Click the [Set ACG] button.
5. Add settings to allow SSL VPN access.
   • Access source: the IP address bandwidth of SSL VPN
   • Allowed port: DB Server port
6. Click the [Apply] button.

3. Check access information of DB Server

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

   • DB access port

Test application server connection

You can use the terminal program, PuTTY, to test if you can properly connect to the application server, follow these steps:

1. Run PuTTY.
2. Enter the IP address from your public IP or port forwarding settings in Host Name (or IP address), and enter the port number from your public IP or port forwarding settings in Port.
   
3. Click [Open].
4. When the PuTTY Security Alert popup window appears, click [Accept].
   
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 from NAVER Cloud Platform console, follow these steps:

Test DB server connection

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

1. Confirm the host IP address and port number to access the DB Server.

• Click Services > Database > Cloud DB for Cache > DB Server.

  • Port number: click the service name of the DB Server to access and view access port

2. Go to Redis official website to check the stable version.
3. Access the application server.
4. Download the stable version of Redis confirmed in step 2.

//As of 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 access port] -c
