Docker中redis集群部署

Docker中redis集群部署

1.创建网卡

docker network create redis --subnet 172.38.0.0/16   #16有255*255设置24的话就255

2.通过shell脚本创建6个redis配置

for port in $(seq 1 6); \\
do \\
mkdir -p /mydata/redis/node-${port}/conf
touch /mydata/redis/node-${port}/conf/redis.conf
cat << EOF >/mydata/redis/node-${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 172.38.0.1${port}
cluster-announce-port 6379
cluster-announce-bus-port 16379
appendonly yes
EOF
done


docker run -p 6371:6379 -p 16371:16379 --name redis-1 \\
    -v /mydata/redis/node-1/data:/data \\
    -v /mydata/redis/node-1/conf/redis.conf:/etc/redis/redis.conf \\
    -d --net redis --ip 172.38.0.11 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
    
docker run -p 6372:6379 -p 16372:16379 --name redis-2 \\
    -v /mydata/redis/node-2/data:/data \\
    -v /mydata/redis/node-2/conf/redis.conf:/etc/redis/redis.conf \\
    -d --net redis --ip 172.38.0.12 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
   
docker run -p 6373:6379 -p 16373:16379 --name redis-3 \\
    -v /mydata/redis/node-3/data:/data \\
    -v /mydata/redis/node-3/conf/redis.conf:/etc/redis/redis.conf \\
    -d --net redis --ip 172.38.0.13 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
    
docker run -p 6374:6379 -p 16374:16379 --name redis-4 \\
    -v /mydata/redis/node-4/data:/data \\
    -v /mydata/redis/node-4/conf/redis.conf:/etc/redis/redis.conf \\
    -d --net redis --ip 172.38.0.14 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
    
docker run -p 6375:6379 -p 16375:16379 --name redis-5 \\
    -v /mydata/redis/node-5/data:/data \\
    -v /mydata/redis/node-5/conf/redis.conf:/etc/redis/redis.conf \\
    -d --net redis --ip 172.38.0.15 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
    
docker run -p 6376:6379 -p 16376:16379 --name redis-6 \\
    -v /mydata/redis/node-6/data:/data \\
    -v /mydata/redis/node-6/conf/redis.conf:/etc/redis/redis.conf \\
    -d --net redis --ip 172.38.0.16 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

3.创建集群

redis-cli --cluster create 172.38.0.11:6379 172.38.0.12:6379 172.38.0.13:6379 1
72.38.0.14:6379 172.38.0.15:6379 172.38.0.16:6379 --cluster-replicas 1

4.查看集群信息
