一、基礎環境
操作系統：CentOS 7.3
將下載好的minio移動到 /opt/minio/文件夾下 或 者進入到/opt/minio/文件夾下使用下面的命令下載：
wget https://dl.minio.io/server/minio/release/linux-amd64/minio
二、準備工作
2.1、機器資源
192.168.129.133 掛載磁盤路徑：/data/minio_data
192.168.129.135 掛載磁盤路徑：/data/minio_data
192.168.129.136 掛載磁盤路徑：/data/minio_data
192.168.129.137 掛載磁盤路徑：/data/minio_data
生成環境強烈建議最少四臺機器，這也是官方的建議要求，這樣的話就可以做到掛掉一臺機器集羣依然可以讀寫，掛掉兩臺機器集羣依然可讀，本文僅以兩臺機器爲例子說明如何搭建集羣
2.2、創建相關目錄（所有節點，上面四臺機器都創建相同路徑的文件夾）
[root@localhost /]# mkdir /data/minio_data/
注意：需要將新建的目錄掛在到對應的磁盤下,磁盤不掛在好，集羣啓動會報錯：找不到磁盤,如下：
[root@localhost /]# df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 475M 0 475M 0% /dev
tmpfs 487M 0 487M 0% /dev/shm
tmpfs 487M 7.7M 479M 2% /run
tmpfs 487M 0 487M 0% /sys/fs/cgroup
/dev/mapper/centos-root 17G 7.4G 9.6G 44% /
/dev/sda1 1014M 137M 878M 14% /boot
tmpfs 98M 0 98M 0% /run/user/0
[root@localhost /]# mount /dev/sda1 /data/minio_data/
mount: /dev/sda1 is already mounted or /data/minio_data busy
/dev/sda1 is already mounted on /boot
/dev/sda1 is already mounted on /data/minio_data
[root@localhost /]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 20G 0 disk
├─sda1 8:1 0 1G 0 part /data/minio_data
└─sda2 8:2 0 19G 0 part
├─centos-root 253:0 0 17G 0 lvm /
└─centos-swap 253:1 0 2G 0 lvm [SWAP]
sr0 11:0 1 4.4G 0 rom
[root@localhost /]#
創建啓動腳本目錄
[root@localhost /]# mkdir /opt/minio/
三、編寫集羣啓動腳本（所有節點配置文件相同）
腳本如下：
[root@localhost /]# vim /opt/minio/run.sh
#!/bin/bash
export MINIO_ACCESS_KEY=Xxyminio
export MINIO_SECRET_KEY=Test123456
/opt/minio/minio server \
http://192.168.129.133/data/minio_data/data1 http://192.168.129.135/data/minio_data/data1 \
http://192.168.129.136/data/minio_data/data1 http://192.168.129.137/data/minio_data/data1
其中，“MINIO_ACCESS_KEY”爲用戶名，“MINIO_SECRET_KEY”爲密碼，密碼不能設置過於簡單，不然minio會啓動失敗
創建好的/opt/minio/目錄下的結構如下圖：
四、編寫服務腳本（所有節點）
[root@localhost minio]# vim /usr/lib/systemd/system/minio.service
[Unit]
Description=Minio service
Documentation=https://docs.minio.io/
[Service]
WorkingDirectory=/opt/minio/
ExecStart=/opt/minio/run.sh
Restart=on-failure
RestartSec=5
[Install]
WantedBy=multi-user.target
其中，“WorkingDirectory”爲啓動腳本目錄，“ExecStart”爲指定集羣啓動腳本
五、啓動測試
5.1、將下載好的minio文件賦予權限
[root@localhost minio]# chmod +x /opt/minio/minio
5.2、賦予啓動文件權限
[root@localhost minio]# chmod +x /opt/minio/run.sh
5.3、依次啓動每個服務器的minio
[root@localhost minio]# systemctl daemon-reload
[root@localhost minio]#
[root@localhost minio]# systemctl start minio
[root@localhost minio]#
[root@localhost minio]# systemctl status minio

[root@localhost minio]#
5.4、測試
瀏覽器輸入集羣任意節點地址+9000端口，即可訪問minio，用戶名密碼爲前面設置的“MINIO_ACCESS_KEY”和“MINIO_SECRET_KEY”，可創建“bucket”並上傳文件測試
