introduce
Redis is an open source in-memory key-value data store. It can be used as a database, cache and message broker and supports various data structures such as strings, hashes, lists, sets, etc. Redis provides high availability via Redis Sentinel including monitoring, notifications, automatic failover. It also provides automatic partitioning among multiple Redis nodes using Redis Cluster.
Install
First update the apt package list:
sudo apt update
Install Redis:
sudo apt install redis-server
After the installation is complete, the Redis service will start automatically. You can check the status of the service by typing:
sudo systemctl status redis-server
Configure Redis Remote Access
Open the Redis configuration file with the vim text editor:
vim /etc/redis/redis.conf
Find the line starting with bind 127.0.0.1 and replace 127.0.0.1 with 0.0.0.0.
Configure the number of databases
Generally not recommended to set! ! !
The default number of databases is 16. If there are too many projects, it may not be enough. For example, a company's server may have dozens or hundreds of projects, all of which require separate db, so you need to modify this here.
Configure password
You can set requirepass in the security module of the configuration file.
restart Redis
sudo systemctl restart redis-server

- Press Backspace to delete characters
- Press the Insert key to insert characters
