原因：权限问题

方案一：修改minio.service下的用户组，用户即可

• 修改用户组，用户

[Unit]

[Service]

EnvironmentFile=-/etc/default/minio

ExecStart=/usr/local/bin/minio server $MINIO_OPTS $MINIO_VOLUMES

# 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

# Disable timeout logic and wait until process is stopped
TimeoutStopSec=infinity

[Install]
WantedBy=multi-user.target

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

• 重载配置

systemctl daemon-reload
systemctl enable minio
service minio start

方案二：赋予对应文件夹读写权限755

• 查看minio存储路径

service minio status
cat /etc/default/minio

• 设置权限 chmod -R 755 [文件夹]
• 重载配置

systemctl daemon-reload
systemctl enable minio
service minio start
