阿里云服务器 CentOS 7.5 64位 docker安装redis集群

https://www.cnblogs.com/hbbbs/articles/10028771.html

阿里云安全组规则添加7000-7005和17000-17005二条（tcp、0.0.0.0/0）。

 

1、拉取redis镜像

docker pull redis
docker images

创建自定义网络

docker network create redis-net

2、在 /usr/local/下建立 redis-cluster文件夹，存放集群配置内容

mkdir /usr/local/redis-cluster
cd /usr/local/redis-cluster

3、建立模版

vim redis-cluster.tmpl

#内容如下
port ${PORT}
protected-mode no
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 192.168.1.210
cluster-announce-port ${PORT}
cluster-announce-bus-port 1${PORT}
appendonly yes

红色部分根据自己的服务器外网IP进行修改

4、创建集群文件

for port in `seq 7000 7005`; do \
  mkdir -p ./${port}/conf \
  && PORT=${port} envsubst < ./redis-cluster.tmpl > ./${port}/conf/redis.conf \
  && mkdir -p ./${port}/data; \
done

5、启动Redis集群

for port in `seq 7000 7005`; do \
 docker run -d -ti -p ${port}:${port} -p 1${port}:1${port} \
 -v /usr/local/redis-cluster/${port}/conf/redis.conf:/usr/local/etc/redis/redis.conf \
 -v /usr/local/redis-cluster/${port}/data:/data \
 --restart always --name redis-${port} --net redis-net \
 --sysctl net.core.somaxconn=1024 redis redis-server /usr/local/etc/redis/redis.conf; \
 done

6、查看docker的IP

#打印 IP
for port in `seq 7000 7005`; do \
 echo -n "$(docker inspect --format '{{ (index .NetworkSettings.Networks "redis-net").IPAddress }}' "redis-${port}")":${port}"  "  ; \
done

7、进入任意一个Docker，启动集群

docker exec -it redis-7000 bash

#在docker中执行   红色部分根据第6步返回的ip信息修改
redis-cli --cluster create

192.168.1.210:7000 192.168.1.210:7001 192.168.1.210:7002 192.168.1.210:7003 192.168.1.210:7004 192.168.1.210:7005 --cluster-replicas 1

8、OK，集群启动完成。最后看看端口映射地址：

docker  ps
