新版MinIO安装，附带问题处理和SSL设置（巨详细）

前些天发现了一个人工智能学习网站，通俗易懂，风趣幽默，最重要的屌图甚多，忍不住分享一下给大家。点击跳转到网站。

下面开始：

前往官网下载需要的二进制文件

wget https://dl.min.io/server/minio/release/linux-amd64/minio -O /usr/local/bin/minio

不清楚系统是amd64、arm64、ppc64le、s390x中的一个可以使用：

uname-m

返回值举例：x86_64，则说明系统为amd64。

[bash: wget: command not found]: 表示系统中没有安装 wget 命令。Debian/Ubuntu 的系统：sudo apt-get update， sudo apt-get install wget；Red Hat/CentOS 的系统：sudo yum install wget；Arch Linux 的系统：sudo pacman -S wget。

为下载的minio文件赋予权限：

chmod +x /usr/local/bin/minio

创建一个存放数据的文件夹(注意，我这里没有且文件夹，所以这个data是创建在了root下面，你们可以根据需求自己调整)：

mkdir data

运行minio（在本地主机的端口号9001上启动MinIO服务器，并将数据存储在

data

目录中，生产环境不建议将data放在根目录，且名字叫data）：

cd /usr/local/bin/minio
./minio server /data --console-address ":9001"

将会看到类似下面的输出：

Formatting 1st pool, 1 set(s), 1 drives per set.
WARNING: Host local has more than 0 drives of set. A host failure will result in data becoming unavailable.

STARTUP WARNINGS:
- Detected Linux kernel version older than 4.0.0 release, there are some known potential performance problems with this kernel version. MinIO recommends a minimum of 4.x.x linux kernel version for best performance
- Detected default credentials 'minioadmin:minioadmin', we recommend that you change these values with 'MINIO_ROOT_USER' and 'MINIO_ROOT_PASSWORD' environment variables
- The standard parity is set to 0. This can lead to data loss.

判断一下是否可以打开控制台（注意防火墙设置）：

curl -I http://你的ip:9001

可以看到返回值第一行是：HTTP/1.1 200 OK ，则说明连接成功。

但这种只是一个简陋的安装过程，实际上我们可能要用systemd 服务单元文件来管理 MinIO 服务。

接着往下走，在目前文件夹中创建一个minio.service文件：

vi minio.service

写入内容：

[Unit]Description=MinIO
Documentation=https://docs.minio.io/
After=network-online.target

[Service]WorkingDirectory=/path/to/data
User=root
#注意--address :9000这里的空格ExecStart=/path/to/minio server --address :9000 --console-address 0.0.0.0:38555 /path/to/data
TimeoutStopSec=600Restart=always
LimitNOFILE=4096LimitNPROC=8192Environment="MINIO_ACCESS_KEY=your_root_username"Environment="MINIO_SECRET_KEY=your_root_password"[Install]WantedBy=multi-user.target

在上面的内容中，将

/path/to/minio

替换为MinIO二进制文件的实际路径（本文中为/usr/local/bin/minio），将

/path/to/data

替换为希望存储数据的目录路径（本文中为 /data）。另外，将

your_root_username

和

your_root_password

替换为你的MinIO根用户的用户名和密码。

保存该文件，并将文件复制到

/etc/systemd/system

目录：

sudo cp minio.service /etc/systemd/system/minio.service

为之前创建的文件赋权：

sudochown-R root:root /usr/local/bin/minio
sudochmod-R755 /usr/local/bin
sudochown-R root:root /data
sudochmod-R755 /data

重新加载配置：

sudo systemctl daemon-reload

使用下面的命令管理minio服务：

# 启动MinIO服务sudo systemctl start minio.service

# 查看MinIo服务状态sudo systemctl status minio.service

# 停止MinIO服务sudo systemctl stop minio.service

# 重启MinIO服务（如果已启动）sudo systemctl restart minio.service

# 设置开机启动sudo systemctl enable minio

# 验证开机启动(输出为 enabled)sudo systemctl is-enabled minio

设置SSL证书（自 2018 年 6 月 30 日起， SSL 已经被MinIO完全弃用，所以我们只能搞点小动作将TLS改为SSL）：

# 可以看到minio默认的隐藏文件夹 .miniols-a#将SSL证书改为：private.key 和 public.crt 放到这里即可cd .minio/certs/

或者在配置文件指定文件夹（指定的文件夹必须实现创建，且有对应权限）：

ExecStart=/path/to/minio server --address :9000 --certs-dir /etc/minio/certs --console-address 0.0.0.0:38555 /path/to/data

遇到问题？

sudo systemctl start minio.service 命令报错：Assertion failed on job for minio.service.

解决方案：1、检查各个文件权限(特别是配置文件)是否赋予。2、检查 /etc/systemd/system/minio.service 配置文件内容是否出错。

检查无误后仍然出错？

运行 以下代码查看日志：

sudo journalctl -u minio.service -b

将会看到类似这样报错信息（问题不一样，打印出的日志也会不一样。切勿硬套！！！）

Jul 01 10:12:23 app systemd[41619]: Failed at step CHDIR spawning /home/minio: No such file or directory
Jul 01 10:12:23 app systemd[1]: minio.service: main process exited, code=exited, status=200/CHDIR
Jul 01 10:12:23 app systemd[1]: Unit minio.service entered failed state.
Jul 01 10:12:23 app systemd[1]: minio.service failed.

Jul 01 10:12:29 app systemd[1]: minio.service: main process exited, code=exited, status=200/CHDIR

可以看出我的问题是：Failed at step CHDIR spawning /home/minio: No such file or directory。

以上都没解决问题?

尝试手动启动

#注意路径换成自己的sudo /path/to/minio server --address :9000 --console-address 0.0.0.0:38555 /path/to/data

如果手动启动可以正常启动，通过systemd 启动失败，则问题可能出在 systemd 服务单元配置上。

如果一切都检查了，什么都没问题。请运行

sudo journalctl -xe-u minio.service

会看到更加详细的日志报告

还有问题？

重装吧，重装可以解决99%的问题。
