访问 https://redis.io/download/#redis-downloads 地址，根据需要选择合适版本下载。
本教程以 5.0.14 版本为例，下面将使用 wget 下载 Redis，如下：
hxstrive@hxstrive:~$ wget https://download.redis.io/releases/redis-5.0.14.tar.gz --2023-02-01 13:08:16-- https://download.redis.io/releases/redis-5.0.14.tar.gz Resolving download.redis.io (download.redis.io)... 45.60.125.1 Connecting to download.redis.io (download.redis.io)|45.60.125.1|:443... connected.

使用 tar -xvzf 命令解压安装包，如下：
hxstrive@hxstrive:~$ tar -xvzf redis-5.0.14.tar.gz redis-5.0.14/ redis-5.0.14/.gitignore redis-5.0.14/00-RELEASENOTES redis-5.0.14/BUGS redis-5.0.14/CONTRIBUTING redis-5.0.14/COPYING redis-5.0.14/INSTALL redis-5.0.14/MANIFESTO ...
使用 make 命令编译 Redis 源码，如下：
hxstrive@hxstrive:~$ cd redis-5.0.14/ hxstrive@hxstrive:~/redis-5.0.14$ make cd src && make all make[1]: Entering directory '/home/hxstrive/redis-5.0.14/src' CC Makefile.dep rm -rf redis-server redis-sentinel redis-cli redis-benchmark redis-check-rdb redis-check-aof *.o *.gcda *.gcno *.gcov redis.info lcov-html Makefile.dep dict-benchmark (cd ../deps && make distclean) make[2]: Entering directory '/home/hxstrive/redis-5.0.14/deps' (cd hiredis && make clean) > /dev/null || true (cd linenoise && make clean) > /dev/null || true ... INSTALL redis-check-aof Hint: It's a good idea to run 'make test' ;) make[1]: Leaving directory '/home/hxstrive/redis-5.0.14/src'
注意：在 Ubuntu 中，如果 gcc 使用国内软件源安装会报错，需要切换成国外软件源（Ubuntu默认软件源）。如下：
# 卸载gcc sudo apt remove gcc # 修改和更新软件源 sudo vi sources.list sudo apt-get update sudo apt-get upgrade # 重新安装gcc sudo apt install gcc
最后，进入到 src 目录，此时生成了 redis-server 和 redis-cli 可执行文件。
启动 redis 服务，如下：
$ ./redis-server
注意这种方式启动 redis 使用的是默认配置。如下：
hxstrive@hxstrive:~/redis-5.0.14$ ./redis-server 12257:C 01 Feb 2023 13:37:14.094 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 12257:C 01 Feb 2023 13:37:14.094 # Redis version=5.0.14, bits=64, commit=00000000, modified=0, pid=12257, just started 12257:C 01 Feb 2023 13:37:14.094 # Warning: no config file specified, using the default config.

也可以通过启动参数告诉 redis 使用指定配置文件使用下面命令启动，如下：
$ ./redis-server redis.conf
redis.conf 是一个默认的配置文件，我们可以根据需要使用自己的配置文件。
启动 redis 服务进程后，就可以使用测试客户端程序 redis-cli 和 redis 服务交互了。例如：
hxstrive@hxstrive:~/redis-5.0.14$ ./redis-cli 127.0.0.1:6379> set url www.hxstrive.com OK 127.0.0.1:6379> get url "www.hxstrive.com" 127.0.0.1:6379>
上面输出可知，成功链接到 Redis 服务，并且写入和读取键 url。
注意
在 Ubuntu 中可以使用如下命令安装 redis 服务，如下：
（1）更新软件源
sudo apt-get update（2）安装 redis 服务
sudo apt-get install redis-server（3）启动 redis 服务
redis-server（4）查看 redis 是否启动？
redis-cli以上命令将打开以下终端：
redis 127.0.0.1:6379> redis 127.0.0.1:6379> ping PONG以上说明我们已经成功安装了redis。
