1、安装redis

首先，访问Redis官网，点击首页的【Get Started】，然后点击Install Redis on Linux

安装

终端依次输入以下命令，如果过程中没有错误提示，则redis安装完成。

sudo apt install lsb-release curl gpg

curl -fsSL https://packages.redis.io/gpg | sudo gpg --dearmor -o /usr/share/keyrings/redis-archive-keyring.gpg

echo "deb [signed-by=/usr/share/keyrings/redis-archive-keyring.gpg] https://packages.redis.io/deb $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/redis.list

sudo apt-get update

sudo apt-get install redis
