- 下载 Redis 镜像
docker pull redis
- 创建存储目录和配置文件
mkdir -p /docker/redis/{7000,7001,7002,7003,7004,7005}/data
- 编辑配置文件redis.conf，使用时去除注释
vim redis.conf
port 7000 ##节点端口
cluster-enabled yes ##cluster 集群模式
cluster-config-file nodes.conf ##集群配置名
cluster-node-timeout 5000 ##超时时间
cluster-announce-ip 10.168.1.229 ##物理机ip
cluster-announce-port 7000 ##节点映射端口
cluster-announce-bus-port 17000 ##节点总线端
masterauth password@123 ##集群密码
requirepass password@123 ##登录密码
appendonly yes ##持久化模式
protected-mode no
- 复制配置文件到各个文件夹/700,/7001/7002...，修改端口和ip
port 7001
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 10.168.1.229
cluster-announce-port 7001
cluster-announce-bus-port 17001
masterauth password@123
requirepass password@123
appendonly yes
protected-mode no
- docker创建6个redis容器
docker run -p 7000:7000 -p 17000:17000 --restart always --name redis-7000 --privileged=true -v /tools/redis/7000/redis7000.conf:/etc/redis/redis.conf -v /tools/redis/7000/data:/data -d redis redis-server /etc/redis/redis.conf
docker run -p 7001:7001 -p 17001:17001 --restart always --name redis-7001 --privileged=true -v /tools/redis/7001/redis7001.conf:/etc/redis/redis.conf -v /tools/redis/7001/data:/data -d redis redis-server /etc/redis/redis.conf
- 进入任意一个容器，创建集群(三主三从，允许挂掉2台)
docker exec -it redis-7000 /bin/bash
redis-cli --cluster create 10.168.1.229:7000 10.168.1.229:7001 10.168.1.229:7002 10.168.1.229:7003 10.168.1.229:7004 10.168.1.229:7005 -a password@123 --cluster-replicas 1
- 进入任意一个容器，查看集群状态
redis-cli --cluster check 10.168.1.229:7000 -a password@123
- 进入任意一个容器，测试集群效果
redis-cli -p 7000 -a password@123 -c
