docker-compose搭建多主机分布式minio

minio介绍

Minio 是个基于 Golang 编写的开源对象存储套件，虽然轻量，却拥有着不错的性能。

官网地址：MinIO | High Performance, Kubernetes Native Object Storage

何为对象存储？我们来看下阿里云 OSS （Object Storage Service）的介绍：

对象存储服务（Object Storage Service，OSS）是一种海量、安全、低成本、高可靠的云存储服务，适合存放任意类型的文件。容量和处理能力弹性扩展，多种存储类型供选择，全面优化存储成本。

对于中小型企业，如果不选择存储上云，那么 Minio 是个不错的选择，麻雀虽小，五脏俱全。当然 Minio 除了直接作为对象存储使用，还可以作为云上对象存储服务的网关层，无缝对接到 Amazon S3、MicroSoft Azure。

一、准备工作

1.在所有机器上 配置主机名解析
cat >> /etc/hosts << EOF
192.168.188.40 minio1
192.168.188.41 minio2
EOF
2.配置时间同步、关闭防火墙和selinux

3.确保主机都安装了docker 以及docker compose

 docker-compose.yml          

version: '3.7'

# Settings and configurations that are common for all containers
# minio节点之间默认使用9000来连通，所以容器把9000暴露出来，9001是console端口，每个节点设置两块磁盘

4.将以上两个文件放在每台机器的同一目录下，去分别启动

#拉镜像
./docker compose  pull

#后台启动容器，三台机器分别对应各自节点 mini01 /minio2 (切勿单台启动多个)

在188-40上执行
./docker compose up -d   minio1  

在188-41上执行
./docker compose up -d   minio2  

5.验证 ，登录 http://192.168.188.40:19001   账号密码  minio  /  minio123
