第一步创建Redis网卡

docker network create redis --subnet 192.168.1.0/24

通过脚本创建6个Redis配置

for port in $(seq 1 6); \ do \ mkdir -p /mydata/redis/node-${port}/conf touch /mydata/redis/node-${port}/conf/redis.conf cat << EOF >>/mydata/redis/node-${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 192.168.1.1${port} cluster-announce-port 6379 cluster-announce-bus-port 16379 appendonly yes EOF done

创建完毕后检查是否成功

[root@D mydata]# cd /mydata/ [root@D mydata]# ls redis [root@D mydata]# cd redis/ [root@D redis]# ls node-1  node-2  node-3  node-4  node-5  node-6 [root@D redis]# cd node-1 [root@D node-1]# ls conf [root@D node-1]# cd conf/ [root@D conf]# ls redis.conf [root@D conf]# cat redis.conf  port 6379 bind 0.0.0.0 cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 cluster-announce-ip 192.168.1.11 cluster-announce-port 6379 cluster-announce-bus-port 16379 appendonly yes [root@D conf]#  docker run -p 637${port}:6379 -p 1637${port}:16379 --name redis-${port} \ -v /mydata/redis/node-${port}/data:/data \ -v /mydata/redis/node-${port}/conf/redis.conf:/etc/redis/redis.conf \ -d --net redis --ip 192.168.1.1${port} redis:5.0 redis-server /etc/redis/redis.conf

创建六台redis

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 192.168.1.11 redis:5.0 redis-server /etc/redis/redis.conf  docker 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 192.168.1.12 redis:5.0 redis-server /etc/redis/redis.conf  docker 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 192.168.1.13 redis:5.0 redis-server /etc/redis/redis.conf  docker 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 192.168.1.14 redis:5.0 redis-server /etc/redis/redis.conf  docker 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 192.168.1.15 redis:5.0 redis-server /etc/redis/redis.conf  docker 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 192.168.1.16 redis:5.0 redis-server /etc/redis/redis.conf

然后进入redis创建集群

docker exec -it redis-1 /bin/sh redis-cli --cluster create 192.168.1.11:6379 192.168.1.12:6379 192.168.1.13:6379 192.168.1.14:6379 192.168.1.15:6379 192.168.1.16:6379 --cluster-replicas 1 # redis-cli --cluster create 192.168.1.11:6379 192.168.1.12:6379 192.168.1.13:6379 192.168.1.14:6379 192.168.1.15:6379 192.168.1.16:6379 --cluster-replicas 1 >>> Performing hash slots allocation on 6 nodes... Master[0] -> Slots 0 - 5460 Master[1] -> Slots 5461 - 10922 Master[2] -> Slots 10923 - 16383 Adding replica 192.168.1.15:6379 to 192.168.1.11:6379 Adding replica 192.168.1.16:6379 to 192.168.1.12:6379 Adding replica 192.168.1.14:6379 to 192.168.1.13:6379 M: a7f6ab5c0d726d45099b63593b12676172b3f86b 192.168.1.11:6379    slots:[0-5460] (5461 slots) master M: 38d476004e54dcb651471fb46f40567f0ee72c89 192.168.1.12:6379    slots:[5461-10922] (5462 slots) master M: 4a260ed09fdc1eaee4896c6acf8185a5ff408faa 192.168.1.13:6379    slots:[10923-16383] (5461 slots) master S: 7cc614aa214debdef74984e5e42becfbc60f4885 192.168.1.14:6379    replicates 4a260ed09fdc1eaee4896c6acf8185a5ff408faa S: b2ec6c8a0ba9c7e8a2773d8f50fd99ef2d6a1de7 192.168.1.15:6379    replicates a7f6ab5c0d726d45099b63593b12676172b3f86b S: 08accdc50545573fd75262bf1d304a0056fd2c6d 192.168.1.16:6379    replicates 38d476004e54dcb651471fb46f40567f0ee72c89 Can I set the above configuration?
