Docker部署minio集群

1.基本定义

由于是非常轻量级的软件，所以架构上也没有这么复杂，他使用操作系统的文件系统作为存储介质，我们在向任意节点写数据的时候，minio会自动同步数据到另外的节点，而机制叫做erasure code（纠删码）来保证集群的稳定，保证数据可用，所以我们建议至少使用4个节点来构建集群。

如果一个N节点的分布式minio，只要有N/2节点在线，数据就是安全的。但是要保证至少有N/2+1个节点来创建新的对象。比如：我们的集群有4个节点，每个节点上一块盘，就算有2两个节点宕机，这个集群仍然是可读的，但是，我们需要3个节点才能让集群写数据。这就是为什么我们要有4个节点来构建集群。

2.机器列表

机器资源	挂载磁盘路径
172.30.0.2	/home/minio/data1
172.30.0.3	/home/minio/data2
172.30.0.4	/home/minio/data3
172.30.0.5	/home/minio/data4

3.网络

# 创建bridge
docker network create -d bridge --subnet 172.30.0.0/16 --gateway 172.30.0.1 minio-network
# 查看信息
docker network ls
docker network inspect minio-network
# 删除
docker network rm networkId

4.mioio安装

# 拉去镜像：指定版本
docker pull minio:RELEASE.2023-02-27T18-10-45Z
