Docker搭建redis集群

1.创建虚拟网卡2.通过脚本创建6个redis配置3.进入容器创建集群4.连接集群查看集群

1.创建虚拟网卡

docker network create redis --subnet 172.38.0.0/16 8b1d0469809421a821079f74e9de5e3bb37257e81b03e7276156564f9add1122 docker network ls NETWORK ID NAME DRIVER SCOPE b5dc3b970355 bridge bridge local 8f2cd56d3d7a host host local 6cf585b80b32 none null local 8b1d04698094 redis bridge local

2.通过脚本创建6个redis配置

for port in `seq 1 6`;\ do \ mkdir -p /redisdata/redis/node-${port}/conf touch /redisdata/redis/node-${port}/conf/redis.conf cat << EOF >/redisdata/redis/node-${port}/conf/redis.conf port 6379 bind 0.0.0.0 cluster-enabled yes cluster-config-file nodes.conf cluster-announce-ip 172.38.0.1${port} cluster-announce-port 6379 cluster-announce-bus-port 16379 appendonly yes EOF docker run -p 637${port}:6379 -p 1637${port}:16379 --name redis-${port} \ -v /redisdata/redis/node-${port}/data:/data \ -v /redisdata/redis/node-${port}/conf/redis.conf:/etc/redis/redis.conf \ -d --network redis --ip 172.38.0.1${port} redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf; \ done

3.进入容器创建集群

redis-cli --cluster create 172.38.0.11:6379 172.38.0.12:6379 172.38.0.13:6379 172.38.0.14:6379 172.38.0.15:6379 172.38.0.16:6379 --cluster-replicas 1

4.连接集群查看集群

/data # redis-cli -c 127.0.0.1:6379> CLUSTER NODES 7fecd5c591884301d46baa2ae6ecf103d4a9e7d2 172.38.0.16:6379@16379 slave cd0bf96ccdfa3e876081ec0d3d1a8e285bb78dc4 0 1599099113348 6 connected 16bd9e562436f149926470e1f862e33dd4f0be70 172.38.0.15:6379@16379 slave 1fe38e4dcd5e85b7d9a1b62135f1dd64db9bf7c2 0 1599099115357 5 connected 1fe38e4dcd5e85b7d9a1b62135f1dd64db9bf7c2 172.38.0.11:6379@16379 myself,master - 0 1599099113000 1 connected 0-5460 cd0bf96ccdfa3e876081ec0d3d1a8e285bb78dc4 172.38.0.12:6379@16379 master - 0 1599099114352 2 connected 5461-10922 eb94ef7939631fd561cd0e4dd2c8e44b3693ea80 172.38.0.14:6379@16379 slave aba1c566bdfe413be0cf5e855abeda62b0c8b2d3 0 1599099112000 4 connected aba1c566bdfe413be0cf5e855abeda62b0c8b2d3 172.38.0.13:6379@16379 master - 0 1599099112344 3 connected 10923-16383
