可以通过官方网站：https://redis.io/download/#redis-downloads 下载想要版本的Redis，或者从GitHub上面下载想要版本的Redis。本文以GitHub方式为例(操作系统以debian为例)：

```bash
sudo apt install libssl-dev
git clone git@github.com:redis/redis.git
cd redis
git checkout 7.0
make BUILD_TLS=yes -j8
make install 
```

安装好之后可以看到可执行文件在/usr/local/bin文件夹下面:

```bash
redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server 
```

- redis-benchmark：官方提供的性能测试工具。
- redis-check-aof：可以用来检查AOF文件是否损坏。
- redis-check-rdb：可以用来检查RDB文件是否损坏。
- redis-cli:官方提供的客户端，用来连接Redis服务，支持集群模式和单实例模式；使用-p指定端口，-h指定ip，-c使用集群模式连接，--tls使用通道加密模式连接。
- redis-sentinel:哨兵模式的启动程序。
- redis-server:Redis服务启动程序，可以直接运行redis-server启动Redis服务，如下

```bash
