笔者使用ubuntu操作系统

下载redis地址：

Index of /releases/， 选择最新的版本下载。

解压后进入目录， 直接make就可以编译。编译成功后在src目录下会生成redis-server和redis-cli可执行文件。

进入redis目录下的utils/create-cluster目录，执行./create-cluster start, 快速启动6个实例

zy@zy-VirtualBox:~/software/redis-7.4.2/utils/create-cluster$ ./create-cluster start
Starting 30001
Starting 30002
Starting 30003
Starting 30004
Starting 30005
Starting 30006
 

运行 ./create-cluster create  把以上创建的6个实例组成一个集群

zy@zy-VirtualBox:~/software/redis-7.4.2/utils/create-cluster$ ./create-cluster create

再返回redis目录，进入src目录，运行./redis-cli -c -p 30001，成功后redis客户端连上了刚才创建的redis集群。

zy@zy-VirtualBox:~/software/redis-7.4.2/src$ ./redis-cli -c -p 30001
