MINIO分布式集群的详细搭建
一、基础环境
操作系统：CentOS 7.3
Minio下载
将下载好的minio移动到 /opt/minio/文件夹下 或 者进入到/opt/minio/文件夹下使用下面的命令下载：
wget https://dl.minio.io/server/minio/release/linux-amd64/minio
二、准备工作
2.1、机器资源
192.168.129.133 挂载磁盘路径：/data/minio_data
192.168.129.135 挂载磁盘路径：/data/minio_data
192.168.129.136 挂载磁盘路径：/data/minio_data
192.168.129.137 挂载磁盘路径：/data/minio_data
生成环境强烈建议最少四台机器，这也是官方的建议要求，这样的话就可以做到挂掉一台机器集群依然可以读写，挂掉两台机器集群依然可读，本文仅以两台机器为例子说明如何搭建集群
2.2、创建相关目录（所有节点，上面四台机器都创建相同路径的文件夹）
[root@localhost /]# mkdir /data/minio_data/注意：需要将新建的目录挂在到对应的磁盘下,磁盘不挂在好，集群启动会报错：找不到磁盘,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 /]#创建启动脚本目录
[root@localhost /]# mkdir /opt/minio/三、编写集群启动脚本（所有节点配置文件相同）
脚本如下：
[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”为用户名，“MINIO_SECRET_KEY”为密码，密码不能设置过于简单，不然minio会启动失败
创建好的/opt/minio/目录下的结构如下图：
四、编写服务脚本（所有节点）
[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”为启动脚本目录，“ExecStart”为指定集群启动脚本
五、启动测试
5.1、将下载好的minio文件赋予权限
[root@localhost minio]# chmod +x /opt/minio/minio5.2、赋予启动文件权限
[root@localhost minio]# chmod +x /opt/minio/run.sh5.3、依次启动每个服务器的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、测试
浏览器输入集群任意节点地址+9000端口，即可访问minio，用户名密码为前面设置的“MINIO_ACCESS_KEY”和“MINIO_SECRET_KEY”，可创建“bucket”并上传文件测试
