该文描述了如何创建Redis集群的文件目录结构，包括使用Bash脚本生成配置文件，并利用模板文件`redis-cluster.tmpl`定制配置。然后，它展示了如何用DockerCompose来启动和配置多个Redis服务，每个服务都有特定的端口映射和数据卷挂载，以实现集群和持久化。最后，`docker-compose.yml`文件定义了所有必要的服务及其依赖关系。

1.创建文件目录

#!/usr/bin/env bash
for port in `seq 6371 6376`; do \
  mkdir -p ${port}/conf \
  && PORT=${port} envsubst < redis-cluster.tmpl > ${port}/conf/redis.conf \
  && mkdir -p ${port}/data;\
done

sh文件增加可执行权限 chmod +x a.sh

文件结构
在这里插入图片描述

2.编写`redis-cluster.tmpl`

port 6379
requirepass 1234
masterauth 1234
protected-mode no
daemonize no
appendonly yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 15000
cluster-announce-ip 192.168.121.135
cluster-announce-port 6379
cluster-announce-bus-port 16379

注释
port 6379                             # 容器内端口
requirepass 1234                      # 密码
masterauth 1234                       # 认证密码
protected-mode no                     # 关闭保护模式
daemonize no                          # 开启后台模式
appendonly yes                        # 开启持久化
cluster-enabled yes                   # 开启集群模式
cluster-config-file nodes.conf        # 集群配置文件
cluster-node-timeout 15000            # 节点超时时间
cluster-announce-ip 192.168.121.135   # 主机IP地址
cluster-announce-port 6379            # 外部映射端口
cluster-announce-bus-port 16379       # 开启集群总线端口,值=cluster-announce-port +10000

3.`docker compose` 文件撰写

# 描述 Compose 文件的版本信息
version: "3.8"

# 定义服务，可以多个
