Docker搭建Redis集群

1.执行脚本建立配置文件

for port in $(seq 1 6); \
do \
mkdir -p /home/redis/node-${port}/conf
touch /home/redis/node-${port}/conf/redis.conf
cat << EOF >>/home/redis/node-${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 10.12.18.235
cluster-announce-port 637${port}
cluster-announce-bus-port 1637${port}
appendonly yes
EOF

2.运行容器

docker run -p 6371:6379 -p 16371:16379 --name redis-1 -v /home/redis/node-1/data:/data -v /home/redis/node-1/conf/redis.conf:/etc/redis/redis.conf -d redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
docker run -p 6372:6379 -p 16372:16379 --name redis-2 -v /home/redis/node-2/data:/data -v /home/redis/node-2/conf/redis.conf:/etc/redis/redis.conf -d redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
docker run -p 6373:6379 -p 16373:16379 --name redis-3 -v /home/redis/node-3/data:/data -v /home/redis/node-3/conf/redis.conf:/etc/redis/redis.conf -d redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
docker run -p 6374:6379 -p 16374:16379 --name redis-4 -v /home/redis/node-4/data:/data -v /home/redis/node-4/conf/redis.conf:/etc/redis/redis.conf -d redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
docker run -p 6375:6379 -p 16375:16379 --name redis-5 -v /home/redis/node-5/data:/data -v /home/redis/node-5/conf/redis.conf:/etc/redis/redis.conf -d redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
docker run -p 6376:6379 -p 16376:16379 --name redis-6 -v /home/redis/node-6/data:/data -v /home/redis/node-6/conf/redis.conf:/etc/redis/redis.conf -d redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

3.进入容器执行Cluster创建命令，建立容器

##进入容器
docker exec -it redis-1 sh
##创建Redis集群
redis-cli --cluster create 10.12.18.235:6371 10.12.18.235:6372 10.12.18.235:6373 10.12.18.235:6374 10.12.18.235:6375 10.12.18.235:6376 --cluster-replicas 1
##查询集群状态
redis-cli -c
cluster info
