Docker搭建Redis Cluster集群

作者：微技術(shù)
數(shù)據(jù)庫(kù) Redis
Redis Cluster采用無(wú)中心結(jié)構(gòu)，每個(gè)節(jié)點(diǎn)保存數(shù)據(jù)和整個(gè)集群狀態(tài),每個(gè)節(jié)點(diǎn)都和其他所有節(jié)點(diǎn)連接。

Redis Cluster采用無(wú)中心結(jié)構(gòu)，每個(gè)節(jié)點(diǎn)保存數(shù)據(jù)和整個(gè)集群狀態(tài),每個(gè)節(jié)點(diǎn)都和其他所有節(jié)點(diǎn)連接。

Redis Cluster提供了一種運(yùn)行Redis安裝的方法，在該安裝中，數(shù)據(jù)會(huì) 在多個(gè)Redis節(jié)點(diǎn)之間自動(dòng)分片。Redis Cluster 在分區(qū)期間還提供了一定程度的可用性，這實(shí)際上是在某些節(jié)點(diǎn)出現(xiàn)故障或無(wú)法通信時(shí)繼續(xù)操作的能力。但是，如果發(fā)生較大故障（例如，大多數(shù)主服務(wù)器不可用時(shí)），集群將停止運(yùn)行。Redis Cluster自動(dòng)分割在多個(gè)節(jié)點(diǎn)之間的數(shù)據(jù)集，一部分節(jié)點(diǎn)出現(xiàn)故障或無(wú)法與集群的其余部分通信時(shí)，繼續(xù)運(yùn)行的能力。

創(chuàng)建網(wǎng)卡

docker network create redis --subnet 172.28.0.0/16

Redis配置

通過(guò)腳本創(chuàng)建6個(gè) 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(yùn)行測(cè)試

添加Redis緩存

會(huì)返回所添加的對(duì)應(yīng)的節(jié)點(diǎn)，如這里返回的是12的節(jié)點(diǎn)

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(duì)應(yīng)的redis節(jié)點(diǎn)

docker stop redis-2

當(dāng)主節(jié)點(diǎn)斷開(kāi)之后，會(huì)自動(dòng)將從節(jié)點(diǎn)切換為主節(jié)點(diǎn)，比如這里將16切換為了主節(jié)點(diǎn)

獲取緩存

如果能取到值，表示集群搭建成功，如下，從16這個(gè)節(jié)點(diǎn)中取到了值
