docker 部署redis集群

1、创建redis网卡

docker network create redis –subnet 172.38.0.0/16 查看网卡信息 docker network ls docker network inspect redis

2、创建redis配置

#使用脚本创建6个redis配置 for port in $(seq 1 6); do mkdir -p /Users/nlsg/sinan/workCode/docker/redis/node-${port}/conf touch /Users/nlsg/sinan/workCode/docker/redis/node-${port}/conf/redis.conf cat << EOF >>/Users/nlsg/sinan/workCode/docker/redis/node-${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-port 6379 cluster-announce-bus-port 16379 appendonly yes EOF done

启动redis

docker run -p 6371:6379 -p 16371:16379 –name redis-1 -v /Users/nlsg/sinan/workCode/docker/redis/node-1/data:/data -v /Users/nlsg/sinan/workCode/docker/redis/node-1/conf/redis.conf:/etc/redis/redis.conf -d –net redis –ip 172.38.0.11 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf #使用命令启动六个 for port in $(seq 1 6); do docker run -p 637${port}:6379 -p 1637${port}:16379 –name redis-${port} -v /Users/nlsg/sinan/workCode/docker/redis/node-${port}/data:/data -v /Users/nlsg/sinan/workCode/docker/redis/node-${port}/conf/redis.conf:/etc/redis/redis.conf -d –net redis –ip 172.38.0.1${port} redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf done

3、创建redis集群

使用cluster 集群配置 #进入某一个redis容器后执行 docker exec -it redis-1 /bin/sh #/bin/bash 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

测试

redis-cli -c #连接redis集群 cluster info #查看集群信息 cluster nodes #查看主从信息 set a 11 #查看存入到那个ip中 停掉服务后 在get get a
