172.17.60.128 minio1
172.17.60.129 minio2
172.17.60.130 minio3
172.17.60.131 minio4

获取Minio

wget https://dl.min.io/server/minio/release/linux-amd64/minio 
chmod +x minio 
sudo mv minio /usr/local/bin/

创建 systemd 系统启动服务文件

vim /usr/lib/systemd/system/minio.service

[Unit]
Description=MinIO
Documentation=https://minio.org.cn/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

EnvironmentFile=-/etc/default/minio
ExecStartPre=/bin/bash -c "if [ -z \"${MINIO_VOLUMES}\" ]; then echo \"Variable MINIO_VOLUMES not set in /etc/default/minio\"; exit 1; fi"
ExecStart=/usr/local/bin/minio server $MINIO_OPTS $MINIO_VOLUMES

# 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})

 修改hosts

# 在所有主机执行
cat >> /etc/hosts <

系统最大文件数修改

# 所有主机执行
echo "*   soft    nofile  65535" >> /etc/security/limits.conf
echo "*   hard    nofile  65535" >> /etc/security/limits.conf

目录创建

数据存储目录 /home/disk{1...4}/minio

groupadd -r minio-user
useradd -M -r -g minio-user minio-user
mkdir /home/disk1 /home/disk2 /home/disk3 /home/disk4
chown minio-user:minio-user /home/disk1 /home/disk2 /home/disk3 /home/disk4

配置文件目录/etc/default/minio

生成用户账户和规定以控制对部署的访问：

MINIO_VOLUMES="http://minio{1...4}:9000/home/disk{1...4}/minio"
MINIO_OPTS="--console-address :9001"
MINIO_ROOT_USER=root
MINIO_ROOT_PASSWORD=BThA9Cop

运行和启动MinIO服务器进程

systemctl enable minio
systemctl start minio

使用以下命令确认服务是否在线和功能正常：

systemctl status minio.service
journalctl -f -u minio.service

打开MinIO控制台

打开浏览器并访问端口 :9001 处的任何 MinIO 主机名 打开 MinIO控制台 登录页面。

例如， http://minio1:9001或者http://172.17.60.128:9001

使用 minio_root_user 和 minio_root_password 登录。

代理集群

生产环境需要使用Nginx将集群地址进行代理，对外统一入口。增加两台nginx上的配置，默认采用负载均衡轮巡机制，对4个地址平均转发。

[root@minio1 conf.d]# vim minio.conf
[root@minio1 conf.d]# cat minio.conf 
# 配置nginx将集群代理端口映射到19000
upstream minio{
    server 172.17.60.128:9000;
    server 172.17.60.129:9000;
    server 172.17.60.130:9000;
    server 172.17.60.131:9000;
}
server {
    listen 19000;
    server_name minio;
    location / {
        proxy_pass http://minio;
        proxy_set_header Host $http_host;
        client_max_body_size 1000m;
        }
}
