参考：https://www.cnblogs.com/heqiuyong/p/10463334.html
一、安装gcc依赖
由于 redis 是用 C 语言开发，安装之前必先确认是否安装 gcc 环境（gcc -v），如果没有安装，执行以下命令进行安装
[root@localhost local]# yum install -y gcc
二、下载并解压安装包
[root@localhost local]# wget http://download.redis.io/releases/redis-5.0.3.tar.gz
[root@localhost local]# tar -zxvf redis-5.0.3.tar.gz
三、cd切换到redis解压目录下，执行编译
[root@localhost local]# cd redis-5.0.3
[root@localhost redis-5.0.3]# make
四、安装并指定安装目录
[root@localhost redis-5.0.3]# make install PREFIX=/usr/local/redis
五、启动服务
5.1前台启动
[root@localhost redis-5.0.3]# cd /usr/local/redis/bin/
[root@localhost bin]# ./redis-server
5.2后台启动
从 redis 的源码目录中复制 redis.conf 到 redis 的安装目录
[root@localhost bin]# cp /usr/local/redis-5.0.3/redis.conf /usr/local/redis/bin/
修改 redis.conf 文件，把 daemonize no 改为 daemonize yes
[root@localhost bin]# vi redis.conf
后台启动
[root@localhost bin]# ./redis-server redis.conf
六、设置开机启动
添加开机启动服务
[root@localhost bin]# vi /etc/systemd/system/redis.service
复制粘贴以下内容：
复制代码
[Unit]
Description=redis-server
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis.conf
PrivateTmp=true
[Install]
WantedBy=multi-user.target
复制代码
注意：ExecStart配置成自己的路径
设置开机启动
[root@localhost bin]# systemctl daemon-reload
[root@localhost bin]# systemctl start redis.service
[root@localhost bin]# systemctl enable redis.service
创建 redis 命令软链接
[root@localhost ~]# ln -s /usr/local/redis/bin/redis-cli /usr/bin/redis
测试 redis
服务操作命令
systemctl start redis.service #启动redis服务
systemctl stop redis.service #停止redis服务
systemctl restart redis.service #重新启动服务
systemctl status redis.service #查看服务当前状态
systemctl enable redis.service #设置开机自启动
systemctl disable redis.service #停止开机自启动
官方安装，但是一般我们的系统需要先安装依赖比如gcc
Installation
From source code
Download, extract and compile Redis with:
$ wget https://download.redis.io/releases/redis-6.2.5.tar.gz
$ tar xzf redis-6.2.5.tar.gz
$ cd redis-6.2.5
$ make
The binaries that are now compiled are available in the src directory. Run Redis with:
$ src/redis-server
You can interact with Redis using the built-in client:
$ src/redis-cli
redis> set foo bar
OK
redis> get foo
"bar"
