docker搭建redis集群

搭建三主三从redis集群。分片+高可用+负载均衡

1 创建redis网络
[root@iZuf65o9ovhniso4w0oji5Z ~]# docker network create redis --subnet 172.38.0.0/16
[root@iZuf65o9ovhniso4w0oji5Z ~]# docker network ls
NETWORK ID     NAME          DRIVER    SCOPE
ebab00407ee4   bridge        bridge    local
f5ddb2cf2442   host          host      local
9167bc2bd975   mynet         bridge    local
ffecf7ecf421   none          null      local
4ded758c3600   redis         bridge    local
2f62a5163aa1   somenetwork   bridge    local
2 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
3 shell执行
[root@iZuf65o9ovhniso4w0oji5Z ~]# 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
[root@iZuf65o9ovhniso4w0oji5Z ~]# cd /mydata
[root@iZuf65o9ovhniso4w0oji5Z mydata]# ls
