使用 Docker Compose 在 CentOS 7 单机服务器上部署多实例 MinIO 集群
1. 准备工作
1.1 主机列表
| IP | 主机名 | 内存（GB） | CPU核数 | 磁盘 | 操作系统 | CPU 架构 |
|---|---|---|---|---|---|---|
| 10.0.0.12 | sdp | 64 | 12 | 500GB | CentOS 7.9.2009 | x86_64 |
说明：
- 每个服务器的 IP 均是静态的；
- 每个服务器的防火墙都已关闭；
- 每个服务器的 SELINUX 已经禁用；
- 每个服务器均存在一个管理员用户 admin，该用户可以免密码执行 sudo 命令；
- 所有操作均使用 admin 用户完成。
1.2 已安装组件
- Docker version 26.1.4
- Docker Compose version v2.27.1
2. 安装步骤
2.1 目录结构
$ tree /opt/app/minio
/opt/app/minio
├── config
│ └── nginx.conf
├── data
│ ├── data1
│ ├── data2
│ ├── data3
│ └── data4
└── docker-compose.yaml
2.2 docker-compose.yaml
说明：使用版本为：RELEASE.2025-04-22T22-12-26Z，此版本之后页面的很多功能需要企业版才可以使用
