本文详细介绍如何使用Docker搭建Redis集群，包括拉取Redis镜像、创建配置文件、启动容器及网络设置。通过脚本自动化生成配置文件和启动容器，实现六个节点的集群部署。

docker pull redis 拉redis镜像

mkdir -p /home/redis-cluster

vim redis-cluster.tmpl

port ${PORT}
protected-mode no
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 192.168.2.88
cluster-announce-port ${PORT}
cluster-announce-bus-port 1${PORT}
appendonly yes

vim test.sh

for port in `seq 7001 7006`; do \
mkdir -p ./${port}/conf \
&& PORT=${port} envsubst < ./redis-cluster.tmpl > ./${port}/conf/redis.conf \
&& mkdir -p ./${port}/data; \
done

如果出现envsubst: command not found

 yum install gettext

chmod +x test.sh && ./test.sh

生成六个redis所用的文件..包括配置和数据存放点

vim test1.sh

for port in `seq 7001 7006`; do \
docker run -d -ti -p ${port}:${port} -p 1${port}:1${port}\
-v /home/redis-cluster/${port}/conf/redis.conf:/usr/local/etc/redis/redis.conf \
-v /home/redis-cluster/${port}/data:/data \
--restart always --name redis-${port} \
--sysctl net.core.somaxconn=1024 redis redis-server /usr/local/etc/redis/redis.conf; \
done
生成六个容器

iptables -I INPUT -p tcp --dport 7001-7006 -j ACCEPT开放端口

iptables -I INPUT -p tcp --dport 17001-17006 -j ACCEPT 开放集群连接端口

进入单个容器

docker exec -it redis-7001 /bin/sh

redis-cli --cluster create 192.168.2.88:7001 192.168.2.88:7002 192.168.2.88:7003 192.168.2.88:7004 192.168.2.88:7005 192.168.2.88:7006
