Minio 是一个基于Apache License v2.0开源协议的对象存储服务。它可以运行在多种操作系统上,包括 Linux 和 Windows 等。
它兼容亚马逊S3云存储服务接口,非常适合于存储大容量非结构化的数据,例如图片、视频、日志文件、备份数据和容器/虚拟机镜像等,而一个对象文件可以是任意大小,从几kb到最大5TB不等。

MinIO Linux 安装

单节点部署

Download:
https://www.minio.org.cn/download.shtml#/linux
使用以下命令下载安装最新版本的稳定 MinIO二进制包, 并设置 $PATH :

[root@localhost ~]# wget https://dl.minio.org.cn/server/minio/release/linux-amd64/minio
[root@localhost ~]# chmod +x minio
[root@localhost ~]# sudo mv minio /usr/local/bin/

image

创建 systemd 系统启动服务文件

创建 minio.service 启动文件,确保文件在
/usr/lib/systemd/system/minio.service

[root@localhost ~]# vi /usr/lib/systemd/system/minio.service

minio.service

[Unit]
Description=MinIO
Documentation=https://min.io/docs/minio/linux/index.html
Wants=network-online.target
After=network-online.target
AssertFileIsExecutable=/usr/local/bin/minio

[Service]
WorkingDirectory=/usr/local

User=minio-user
Group=minio-user
ProtectProc=invisible

# MinIO RELEASE.2023-05-04T21-44-30Z adds support for Type=notify (https://www.freedesktop.org/software/systemd/man/systemd.service.html#Type=)
# This may improve systemctl setups where other services use `After=minio.server`
# Uncomment the line to enable the functionality
# Type=notify

# Let systemd restart this service always
Restart=always

# Specifies the maximum file descriptor number that can be opened by this process
LimitNOFILE=65536

# Specifies the maximum number of threads this process can create
TasksMax=infinity

# Disable timeout logic and wait until process is stopped
TimeoutStopSec=infinity
SendSIGKILL=no

[Install]
WantedBy=multi-user.target

# Built for ${project.name}-${project.version} (${project.name})

默认情况下,
minio.service
文件以
minio-user
用户和组的身份运行。 您可以使用
groupadd

useradd
创建用户和组。 命令。下面的示例创建了用户和组,并设置了权限 来访问供 MinIO 使用的文件夹路径。这些命令通常 需要 root ( sudo ) 权限。

[root@localhost ~]# groupadd -r minio-user
[root@localhost ~]# useradd -M -r -g minio-user minio-user
# 存储路径
[root@localhost ~]# chown minio-user:minio-user /mnt/data
chown: 无法访问"/mnt/data": 没有那个文件或目录
[root@localhost ~]# mkdir /mnt/data
[root@localhost ~]# chown minio-user:minio-user /mnt/data

本例中的驱动器路径由 MINIO_VOLUMES 环境变量指定。更改此处和环境变量文件中的值,使其与 MinIO 打算使用的驱动器路径相匹配。

创建环境变量文件


/etc/default/minio
创建环境变量文件。 MinIO 服务器容器可以将此文件作为所有
environment variables
下面的示例提供了一个起始环境文件:
密码不能小于8个字符, 否则无法启动

[root@localhost ~]# vi /etc/default/minio
# MINIO_ROOT_USER and MINIO_ROOT_PASSWORD sets the root account for the MinIO server.
# This user has unrestricted permissions to perform S3 and administrative API operations on any resource in the deployment.
# Omit to use the default values 'minioadmin:minioadmin'.
# MinIO recommends setting non-default values as a best practice, regardless of environment
# 用户名长度不能小于3个字符
MINIO_ROOT_USER=admin
# 密码不能小于8个字符, 否则无法启动
MINIO_ROOT_PASSWORD=minioadmin

# MINIO_VOLUMES sets the storage volume or path to use for the MinIO server.

MINIO_VOLUMES="/mnt/data"

# MINIO_OPTS sets any additional commandline options to pass to the MinIO server.
# For example, `--console-address :9001` sets the MinIO Console listen port
MINIO_OPTS="--console-address :9001"

启动MinIO服务

启动 MinIO SNSD 部署即服务:

[root@localhost ~]# sudo systemctl start minio.service

使用以下命令确认服务是否在线和功能正常:

[root@localhost ~]# sudo systemctl status minio.service
[root@localhost ~]# journalctl -f -u minio.service

自启动,将进程作为主机引导的一部分,在服务器重启的过程中该进程会自动重启,而不用再进行手动管理。

[root@localhost ~]# sudo systemctl enable minio.service

image

连接到MinIO服务

浏览器中输入:
http://localhost:9001
登录MinIO的用户名和密码配置参数为
MINIO_ROOT_USER

MINIO_ROOT_PASSWORD
这些配置可以在在容器指定的环境文件中进行修改。
image
image
您可以使用MinIO控制台进行一般管理任务,如身份和访问管理、指标和日志监控或服务器配置。每个MinIO服务器都包含其自己的嵌入式MinIO控制台。 如果您的本地主机防火墙允许外部访问控制台端口,则同一网络上的其他主机可以使用您的本地主机的IP地址或主机名访问控制台。
