The version of redis on window is up to 3.2
Download address:
You will see after entering Go to such a page, click Download
# and then unzip the downloaded file and put it under your own drive letter
Click redis-server to start the redis service, and then open a terminal to use redis
window installation of redis is very simple, you can do it during the learning process Use window to learn, but the actual work is still based on Linux.
linux installation Redis
On Linux, you can use yum to install, or you can use source code to install. Here Kaka uses compiled installation. The installation version is 4.0
Download the redis installation package
wgethttp://download.redis.io/releases/redis-4.0.8.tar.gz
Unzip the installation package
cd redis-4.0.8Execute make
Then Move redis-4.0.8 to /usr/local
mv redis-4.0.8 /usr/local
Modify redis.conf configuration
Set password
##Comment bind 127.0.0.1 (this can only be connected using the local machine, so it needs to be commented out)
The default is non-daemon mode
Exit after completing the above operations
When using redis, remember to enter a password. If you don’t want to enter a password, you can do the above operation without setting a password
The above is the installation of redis on linux
Here I’ll talk about turning off the redis service. This is not turned off because the password is set, so we need to add the password to turn off the redis service
You can see that there is a redis process running now
The correct shutdown method redis-cli -a fang1996 shutdown
Docker installation redis
Prerequisite: You have docker on centos
First pull the redis4.0 image
docker pull redis:4.0
View the image docker image ls
At this time the redis image has been pulled down
I have defined a network here 172.10.0.0/16
Create redis container: docker run -itd --name redis --net mynetwork -p 6380:6379 --ip 172.10.0.2 redis:4.0
Enter docker in the redis container exec -it redis /bin/bash
There is no redis.conf configuration file in the container at this time. Exit the container and copy a copy to the redis container
The above is the detailed content of Redis installation guide covers Windows, Linux, Docker. For more information, please follow other related articles on the PHP Chinese website!

Redis is a powerful database solution because it provides fast performance, rich data structures, high availability and scalability, persistence capabilities, and a wide range of ecosystem support. 1) Extremely fast performance: Redis's data is stored in memory and has extremely fast read and write speeds, suitable for high concurrency and low latency applications. 2) Rich data structure: supports multiple data types, such as lists, collections, etc., which are suitable for a variety of scenarios. 3) High availability and scalability: supports master-slave replication and cluster mode to achieve high availability and horizontal scalability. 4) Persistence and data security: Data persistence is achieved through RDB and AOF to ensure data integrity and reliability. 5) Wide ecosystem and community support: with a huge ecosystem and active community,

Key features of Redis include speed, flexibility and rich data structure support. 1) Speed: Redis is an in-memory database, and read and write operations are almost instantaneous, suitable for cache and session management. 2) Flexibility: Supports multiple data structures, such as strings, lists, collections, etc., which are suitable for complex data processing. 3) Data structure support: provides strings, lists, collections, hash tables, etc., which are suitable for different business needs.

The core function of Redis is a high-performance in-memory data storage and processing system. 1) High-speed data access: Redis stores data in memory and provides microsecond-level read and write speed. 2) Rich data structure: supports strings, lists, collections, etc., and adapts to a variety of application scenarios. 3) Persistence: Persist data to disk through RDB and AOF. 4) Publish subscription: Can be used in message queues or real-time communication systems.

Redis supports a variety of data structures, including: 1. String, suitable for storing single-value data; 2. List, suitable for queues and stacks; 3. Set, used for storing non-duplicate data; 4. Ordered Set, suitable for ranking lists and priority queues; 5. Hash table, suitable for storing object or structured data.

Redis counter is a mechanism that uses Redis key-value pair storage to implement counting operations, including the following steps: creating counter keys, increasing counts, decreasing counts, resetting counts, and obtaining counts. The advantages of Redis counters include fast speed, high concurrency, durability and simplicity and ease of use. It can be used in scenarios such as user access counting, real-time metric tracking, game scores and rankings, and order processing counting.

Use the Redis command line tool (redis-cli) to manage and operate Redis through the following steps: Connect to the server, specify the address and port. Send commands to the server using the command name and parameters. Use the HELP command to view help information for a specific command. Use the QUIT command to exit the command line tool.

Redis cluster mode deploys Redis instances to multiple servers through sharding, improving scalability and availability. The construction steps are as follows: Create odd Redis instances with different ports; Create 3 sentinel instances, monitor Redis instances and failover; configure sentinel configuration files, add monitoring Redis instance information and failover settings; configure Redis instance configuration files, enable cluster mode and specify the cluster information file path; create nodes.conf file, containing information of each Redis instance; start the cluster, execute the create command to create a cluster and specify the number of replicas; log in to the cluster to execute the CLUSTER INFO command to verify the cluster status; make

To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.
