简介

Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions, and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster.

# 安装基础包
yum install gcc make -y

# 下载资源包
cd /usr/local/src && wget https://download.redis.io/releases/redis-6.2.6.tar.gz

# 解压
tar xzf redis-6.2.6.tar.gz && cd redis-6.2.6

# 编译安装
make && make install
# PS：
# 问题：由于未安装gcc，导致第一次make失败，在安装gcc安装后，再次make报错fatal error: jemalloc/jemalloc.h: No such file or directory
# 解决：该问题是由于第一轮make失败有残留导致，需清理后再编译，命令：make distclean && make && make install

# 生成配置文件
mkdir /etc/redis && cp redis.conf /etc/redis/

# 创建数据持久化目录
mkdir /var/lib/redis
