Redis for infrastructure

In the process of project development, some information has a very low frequency of change but is frequently accessed. We often store this information in the cache. Currently, Redis is definitely worth your use plan in the cache component.For more details, please refer to the official website https://redis.io/.This article is mainly about quick setup and easy use.

(1) Environmental requirements

1. Centos 7.5.1804
2. Docker 18.06.1-ce
3. Redis: latest

Mainly share low code, microservices, containersa>The content of the content, SAAS, and system architecture, I hope everyone likes, comments, and pays attention.

(2) Installation settings

1. Image acquisition

a) First execute docker pull redis to obtain the redis image file. Depending on your network environment, it will take a while to download it. Then you can use docker images | grep redis to view the downloaded redis image.

1. Service Installation

a) The default port of Redis is 6379. If you want to modify the default port, you can specify the port number you want to modify in the command to create the container and execute

docker run -p 6379:6379 -v $PWD/data:/data -d redis redis-server --appendonly yes

Command to create a redis service. If 6379 is already occupied by other programs, change it to an unoccupied port number and execute

docker ps|grep redis

You can see the following information, indicating that the service has been started.

1. Client Link and Test

a) Install the client

We use the Redis client link test, if the client is not installed, click to downloadhttps://pan.baidu.com/s/1Fls2eI_uf6sXYkr4jsFFyA, install.Then open the effect as follows

b) Links

The name can be entered as you like, the address is the ip installed by our redis service or domain name, the port is generally the default port 6379. If you have modified the default port, fill in your modified port interface. I have not enabled the security policy here. If it is enabled, please fill in the actual setting information. Finally, click Test Connection, if the information is verifiedIf passed, a message indicating that the connection to the Redis server is successful will pop up.

c) Test

Click the link we just created to see the list of DBs as shown below. Feel free to click the plus sign near one of the DBs.

The Key-Value window pops up as follows, enter the key name, Value type and Value, and then click Save, so that we have created a simple KV cache item.

Mainly share low-code, microservices, containerization, SAAS, and system architecture.
