一、Redis数据库介绍
1.Redis简介
Redis 是完全开源的，遵守 BSD 协议，是一个高性能的 key-value 数据库。
2.Redis特点
- Redis支持数据的持久化，可以将内存中的数据保存在磁盘中，重启的时候可以再次加载进行使用。
- Redis不仅仅支持简单的key-value类型的数据，同时还提供list，set，zset，hash等数据结构的存储。
- Redis支持数据的备份，即master-slave模式的数据备份。
二、检查本地系统版本
代码语言：shell复制[root@node data]# cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"
CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"三、下载Redis软件包
1.下载软件
代码语言：shell复制[root@node redis]# wget https://download.redis.io/releases/redis-6.2.6.tar.gz

代码语言：shell复制[root@node redis]# ls
redis-6.2.6.tar.gz四、安装redis前环境准备工作
1.解压redis压缩包
代码语言：shell复制[root@node redis]# tar -xzf redis-6.2.6.tar.gz
[root@node redis]# ls
redis-6.2.6 redis-6.2.6.tar.gz2.安装gcc模块
代码语言：shell复制[root@node redis]# yum -y install gcc automake autoconf libtool make
