docker desktop for windows 4.23.0redis 7.2
一、前提准备
1. redis配置文件
因为Redis 7.2 docker镜像里面没有配置文件所以需要去redis官网下载一个复制里面的redis.conf 博主这里用的是7.2.3版本的redis.conf这个文件就在解压后第一层文件夹里。
2. 下载redis镜像
docker pull redis:7.23. 文件夹结构
如下建立cluster文件夹并复制出三份conf文件到如图位置。
二、docker-compose
docker-compose文件具体内容如下。
version: 3.8networks:redis-network:driver: bridgeipam:driver: defaultconfig:- subnet: 172.30.1.0/24services:redis-master:container_name: redis-masterimage: redis:7.2volumes:- ./master/redis.conf:/usr/local/etc/redis/redis.conf
# - ./master/data:/dataports:- 7001:6379command: [redis-server, /usr/local/etc/redis/redis.conf]networks:redis-network:ipv4_address: 172.30.1.2redis-replica1:container_name: redis-replica1image: redis:7.2volumes:- ./replica1/redis.conf:/usr/local/etc/redis/redis.conf
# - ./replica1/data:/dataports:- 7002:6379command: [redis-server, /usr/local/etc/redis/redis.conf]depends_on:- redis-masternetworks:redis-network:ipv4_address: 172.30.1.3redis-replica2:container_name: redis-replica2image: redis:7.2volumes:- ./replica2/redis.conf:/usr/local/etc/redis/redis.conf
# - ./replica2/data:/dataports:- 7003:6379command: [redis-server, /usr/local/etc/redis/redis.conf]depends_on:- redis-masternetworks:redis-network:ipv4_address: 172.30.1.4需要注意以下几点
这里自定义了bridge子网并限定了范围如果该范围已经被使用请更换。这里没有对data进行-v挂载如果要挂载请注意宿主机对应文件夹权限问题。
三、主从配置
1.主节点配置文件
主节点对应的配置文件是master/redis.conf需要做以下修改 bind 将bind 127.0.0.1 -::1修改为bind 0.0.0.0监听来自任意网络接口的连接。 protected-mode 将protected-mode设置为no关闭保护模式接收远程连接。 masterauth 将masterauth设置为1009这是从节点连接到主节点的认证密码你可以指定为其他的。 requirepass 将requirepass设置为1009这是客户端连接到本节点的认证密码你可以指定为其他的。
2.从节点配置文件
把上面主节点的配置文件复制粘贴然后继续做以下更改就可以作为从节点配置文件了
replicaof 旧版本添加一行replicaof redis-master 6379表示本节点为从节点并且主节点ip为redis-master端口为6379。这里你也可以把ip填成172.30.1.2因为在docker-compose中我们为各节点分配了固定的ip以及端口是6379而不是映射的700x这些都是docker的知识这里不再赘述。 redis在5.0引入了replica的概念来替换slave所以后续的新版本推荐使用replicaof即便slaveof目前仍然支持。 四、运行
配置好三个节点的配置文件后用以下命令运行整个服务
docker-compose -p redis-cluster up -d查看主节点日志可以看到主节点向172.30.1.3和172.30.1.4两个从节点同步数据并且连接正常以及一系列success。

用你喜欢的docker容器连接工具或者redis连接工具来连接主节点redis服务只要能进入redis-cli就行。这里以docker容器连接为例。
主节点设置一个字段并查看从节点信息
rootac1ecfc4e3a5:/data# redis-cli

127.0.0.1:6379 set num 67899
