1.關(guān)閉防火墻+啟動docker后臺服務(wù)

?systemctl start docker

2.新建6個docker容器redis實例

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

命令分步解釋

docker run ? ? ? ? ?創(chuàng)建并運行docker容器實例
--name redis-node-6 容器名字
--net host ? ? ? ? ? ?使用宿主機的IP和端口，默認
--privileged=true ? ?獲取宿主機root用戶權(quán)限
-v /data/redis/share/redis-node-6:/data 容器卷，宿主機地址:docker內(nèi)部地址
redis:6.0.8 ? ? ? ? ? ?redis鏡像和版本號
--cluster-enabled yes ? ?開啟redis集群
--appendonly yes ? ?開啟持久化
--port 6386 ? ? ? ? ? ?redis端口號
