Docker搭建Redis Cluster集群

作者：微技術
數據庫 Redis
Redis Cluster采用無中心結構，每個節點保存數據和整個集群狀態,每個節點都和其他所有節點連接。

Redis Cluster采用無中心結構，每個節點保存數據和整個集群狀態,每個節點都和其他所有節點連接。

Redis Cluster提供了一種運行Redis安裝的方法，在該安裝中，數據會 在多個Redis節點之間自動分片。Redis Cluster 在分區期間還提供了一定程度的可用性，這實際上是在某些節點出現故障或無法通信時繼續操作的能力。但是，如果發生較大故障（例如，大多數主服務器不可用時），集群將停止運行。Redis Cluster自動分割在多個節點之間的數據集，一部分節點出現故障或無法與集群的其余部分通信時，繼續運行的能力。

創建網卡

docker network create redis --subnet 172.28.0.0/16

Redis配置

通過腳本創建6個 redis 配置

for port in $(seq 1 6); \
do \
mkdir -p ~/redis/node-${port}/conf
touch ~/redis/node-${port}/conf/redis.conf
cat << EOF > ~/redis/node-${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 172.28.0.1${port}
cluster-announce-port 6379
cluster-announce-bus-port 16379
appendonly yes
EOF
done

運行容器

-v ~/redis/node-1/data:/data \
-v ~/redis/node-1/conf/redis.conf:/etc/redis/redis.conf \
-d --net redis --ip 172.28.0.11 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

運行測試

添加Redis緩存

會返回所添加的對應的節點，如這里返回的是12的節點

set name weijishu
-> Redirected to slot [5798] located at 172.28.0.12:6379
OK

停止容器

停止剛添加緩存的對應的redis節點

docker stop redis-2

當主節點斷開之后，會自動將從節點切換為主節點，比如這里將16切換為了主節點

cluster nodes

獲取緩存

如果能取到值，表示集群搭建成功，如下，從16這個節點中取到了值

get name
-> Redirected to slot [5798] located at 172.28.0.16:6379
"weijishu"
