Redis 的安装

Redis 是一种支持多种数据结构的缓存，也是一种存储。具体看 Redis 的官网

Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries 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.

它的安装比较容易，具体如下：

• 下载源码
  将源码下载到 /usr/src 目录下：

cd /usr/src
wget http://download.redis.io/releases/redis-5.0.8.tar.gz

• 解压源码

tar xf redis-5.0.8.tar.gz

• 编译
  进入 redis 目录，进行编译

cd redis-5.0.8
make

• 安装
  将 Redis 安装到 /usr/local/redis 目录下

make PREFIX=/usr/local/redis install

• 拷贝配置文件
  从 /usr/local/redis-5.0.8 目录下拷贝 redis.conf 文件到 /usr/local/redis 目录下

cd /usr/local/redis
cp /usr/src/redis-5.0.8/redis.conf ./

• 启动 Redis
  启动 /usr/local/redis/bin 目录下的 redis-server 文件，启动的配置文件是 /usr/local/redis 目录下的 redis.conf 文件

cd /usr/local/redis
./bin/redis-server redis.conf
