主3从redis集群配置

1.关闭防火墙+启动docker后台服务

 systemctl start docker

2.新建6个docker容器redis实例

docker run -d –name redis-node-1 –net host –privileged=true -v /home/redis/share/redis-node-1:/data redis:6.0.8 –cluster-enabled yes –appendonly yes –port 6381
 
docker run -d –name redis-node-2 –net host –privileged=true -v /home/redis/share/redis-node-2:/data redis:6.0.8 –cluster-enabled yes –appendonly yes –port 6382
 
docker run -d –name redis-node-3 –net host –privileged=true -v /home/redis/share/redis-node-3:/data redis:6.0.8 –cluster-enabled yes –appendonly yes –port 6383
 
docker run -d –name redis-node-4 –net host –privileged=true -v /home/redis/share/redis-node-4:/data redis:6.0.8 –cluster-enabled yes –appendonly yes –port 6384
 
docker run -d –name redis-node-5 –net host –privileged=true -v /home/redis/share/redis-node-5:/data redis:6.0.8 –cluster-enabled yes –appendonly yes –port 6385
 
docker run -d –name redis-node-6 –net host –privileged=true -v /home/redis/share/redis-node-6:/data redis:6.0.8 –cluster-enabled yes –appendonly yes –port 6386

命令分步解释

docker run          创建并运行docker容器实例
–name redis-node-6 容器名字
–net host            使用宿主机的IP和端口，默认
–privileged=true    获取宿主机root用户权限
-v /data/redis/share/redis-node-6:/data 容器卷，宿主机地址:docker内部地址
redis:6.0.8            redis镜像和版本号
–cluster-enabled yes    开启redis集群
–appendonly yes    开启持久化
–port 6386            redis端口号

运行结果
