启动6个Redis容器，上面三个是主，后面三个是备！
2.搭建步骤 2.1 创建Redis网络

docker network create redis --subnet 172.38.0.0/16

2.2 创建6个Redis配置

for port in $(seq 1 6); \ do \ mkdir -p /mydata/redis/node-${port}/conf touch /mydata/redis/node-${port}/conf/redis.conf cat <>/mydata/redis/node-${port}/conf/redis.conf port 6379 bind 0.0.0.0 cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 cluster-announce-ip 172.38.0.1${port} cluster-announce-port 6379 cluster-announce-bus-port 16379 appendonly yes EOF done

2.3 启动容器

docker run -p 6371:6379 -p 16371:16379 --name redis-1 -v /mydata/redis/node-1/data:/data -v /mydata/redis/node-1/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.38.0.11 redis redis-server /etc/redis/redis.confdocker run -p 6372:6379 -p 16372:16379 --name redis-2 -v /mydata/redis/node-2/data:/data -v /mydata/redis/node-2/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.38.0.12 redis redis-server /etc/redis/redis.confdocker run -p 6373:6379 -p 16373:16379 --name redis-3 -v /mydata/redis/node-3/data:/data -v /mydata/redis/node-3/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.38.0.13 redis redis-server /etc/redis/redis.confdocker run -p 6374:6379 -p 16374:16379 --name redis-4 -v /mydata/redis/node-4/data:/data -v /mydata/redis/node-4/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.38.0.14 redis redis-server /etc/redis/redis.confdocker run -p 6375:6379 -p 16375:16379 --name redis-5 -v /mydata/redis/node-5/data:/data -v /mydata/redis/node-5/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.38.0.15 redis redis-server /etc/redis/redis.confdocker run -p 6376:6379 -p 16376:16379 --name redis-6 -v /mydata/redis/node-6/data:/data -v /mydata/redis/node-6/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.38.0.16 redis redis-server /etc/redis/redis.conf
