docker 创建redis 集群 部署

1. 创建 网卡

docker network create redis --subnet 172.110.110.0/16

2. 使用脚本创建redis配置文件

for port in $(seq 1 6); \

do \

mkdir -p /root/redis/node-${port}/conf

touch /root/redis/node-${port}/conf/redis.conf

cat << EOF >/root/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 172.110.110.1${port}

cluster-announce-port 6379

cluster-announce-bus-port 16379

appendonly yes

EOF

done

 

 

3. 启动redis

docker run -p 6371:6379 -p 16371:16379 --name redis-1  -v /root/redis/node-1/data:/data  -v /root/redis/node-1/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.110.110.11 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

 

docker run -p 6372:6379 -p 16372:16379 --name redis-2  -v /root/redis/node-2/data:/data  -v /root/redis/node-2/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.110.110.12 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

docker run -p 6373:6379 -p 16373:16379 --name redis-3  -v /root/redis/node-3/data:/data  -v /root/redis/node-3/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.110.110.13 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

docker run -p 6374:6379 -p 16374:16379 --name redis-4  -v /root/redis/node-4/data:/data  -v /root/redis/node-4/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.110.110.14 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

docker run -p 6375:6379 -p 16375:16379 --name redis-5  -v /root/redis/node-5/data:/data  -v /root/redis/node-5/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.110.110.15 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

docker run -p 6376:6379 -p 16376:16379 --name redis-6  -v /root/redis/node-6/data:/data  -v /root/redis/node-6/conf/redis.conf:/etc/redis/redis.conf -d --net redis --ip 172.110.110.16 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

4. 进入redis 

docker exec -it redis-1 /bin/sh

4. 创建集群

redis-cli --cluster create 172.110.110.11:6379 172.110.110.12:6379 172.110.110.13:6379 172.110.110.14:6379 172.110.110.15:6379 172.110.110.16:6379 --cluster-replicas 1
