docker-redis集群

此文只作为学习记录

1、创建6个节点
3主3从方式，从为了同步备份，主进行slot数据分片 

for port in $(seq 7001 7006); \
do \
mkdir -p /mydata/redis/node-${port}/conf
touch /mydata/redis/node-${port}/conf/redis.conf
cat </mydata/redis/node-${port}/conf/redis.conf
port ${port}
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 192.168.56.10
cluster-announce-port ${port}
cluster-announce-bus-port 1${port}
appendonly yes
EOF
docker run -p ${port}:${port} -p 1${port}:1${port} --name redis-${port} \
   -v /mydata/redis/node-${port}/data:/data \
   -v /mydata/redis/node-${port}/conf/redis.conf:/etc/redis/redis.conf \
   -d redis:5.0.7 redis-server /etc/redis/redis.conf; \
done 

#停用或删除所有节点

docker stop $(docker ps -a |grep redis-700 |awk '{print $1}')
docker rm $(docker ps -a |grep redis-700 |awk '{print $1}')

2、创建集群
2.1进入上一步已创建的任一容器中

docker exec -it redis-7001 /bin/bash

2.2 创建集群 

redis-cli --cluster create 192.168.56.10:7001 192.168.56.10:7002 192.168.56.10:7003
192.168.56.10:7004 192.168.56.10:7005 192.168.56.10:7006 --cluster-replicas 1

set一些数据，可以看到具体存储到那个节点
