22.Docker实战，部署Redis集群

分片+高可用+负载均衡

创建redis的网络

docker network create redis --subnet 172.38.0.0/16

通过脚本创建六个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

启动

docker run -p 6371:6379 -p 16371:16379 --name redis-1 \
-v /mydata/redis/node-1/data:/data\
-v /mydate/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

创建集群

redis-cli --cluster create 172.38.0.11:6379 172.38.0.12:6379 .... --cluster-replicas 1

# 连接集群
redis-cli -c
# 查看集群信息
cluster info
