分布式纠删码部署MinIO（二进制Systemd托管+Nginx负载均衡）以及客户端命令的使用

前言

上集说到，MinIO的基本情况，详情请戳：

开源对象存储工具：MinIO

4年前 (2020-08-05) 1

环境准备

• 前四个节点，安装MinIO，四个数据盘分别挂载至/data1、/data2、/data3、/data4
• 第五个节点安装Nginx，做负载均衡
• 五个节点均关闭防火墙：

systemctl stop firewalld
systemctl disable firewalld

部署

准备配置文件（四个节点均添加）

• 准备minio配置文件至/etc/default/minio，内容如下

# AK/SK自定义即可
MINIO_ACCESS_KEY="xxx"
MINIO_SECRET_KEY="xxx"
MINIO_VOLUMES=http://host{1...4}/data{1...4}
MINIO_OPTS="--address :9000"

准备minio二进制文件（四个节点均执行）

• 下载minio的二进制文件，移动至节点的/usr/local/bin/目录下

http://dl.minio.org.cn/server/minio/release/linux-amd64/minio

• 准备systemd托管services文件，内容如下

[Unit]
Description=MinIO
Documentation=https://docs.min.io
Wants=network-online.target
After=network-online.target
AssertFileIsExecutable=/usr/local/bin/minio

[Service]
WorkingDirectory=/usr/local/

User=root
Group=root

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

# Let systemd restart this service always
Restart=always

# Specifies the maximum file descriptor number that can be opened by this process
LimitNOFILE=65536

# 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})

执行启动程序（四个节点均执行）

systemctl daemon-load
systemctl start minio
systemctl enable minio

验证启动是否成功

• 四个节点查看是否监听9000端口（或者修改过启动端口，可以看相应的端口）

ss -anlp | grep 9000
---
tcp    LISTEN     0      128      :::9000                 :::*                   users:(("minio",pid=15697,fd=7))

• 浏览器访问http://IP:9000，IP分别使用四个节点的IP都访问一下，Access Key以及Secret Key为配置文件中设置的

Nginx负载均衡

安装Nginx

rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
yum install -y nginx
systemctl start nginx
systemctl enable nginx

services配置文件（minio.conf）准备

• 将配置文件放置/etc/nginx/conf.d/目录下

upstream minio {
       server 192.168.2.10:9000 weight=10 max_fails=2 fail_timeout=30s;
       server 192.168.2.11:9000 weight=10 max_fails=2 fail_timeout=30s;
       server 192.168.2.12:9000 weight=10 max_fails=2 fail_timeout=30s;
       server 192.168.2.13:9000 weight=10 max_fails=2 fail_timeout=30s;
    }
server {
    listen 9000;
        server_name 192.168.2.14;
        charset utf-8;
        default_type text/html;
        location / {
            proxy_set_header Host $http_host;
            proxy_set_header X-Forwarded-For $remote_addr;
            client_body_buffer_size 10M;
            client_max_body_size 100G;
            proxy_buffers 1024 4k;
            proxy_read_timeout 300;
            proxy_next_upstream error timeout http_404;
            proxy_pass http://minio;
        }
}

生效负载均衡配置

systemctl daemon-reload
systemctl restart nginx

访问

• 使用http://lvs-ip:9000来访问即可

客户端工具

• 下载：http://dl.minio.org.cn/client/mc/release/linux-amd64/mc，赋予执行权限
• 与服务端关联

mc config host add minio http://192.168.2.14:90000 <AK> <SK>
