MinIO前期部署（三）

Nginx负载均衡设定(适合集群部署)

参考资料（英文）：https://min.io/docs/minio/linux/integrations/setup-nginx-proxy-with-minio.html#integrations-nginx-proxy

NGINX官方网站：https://nginx.org/

安装nginx（nginx服务器地址：192.168.182.134）

apt install nginx

修改nginx配置文件

nano /etc/nginx/nginx.conf

在http块中添加如下配置：

upstream minio_api {
   least_conn; #采用最小连接数负载均衡算法，除此以外还有轮询、ip_hash、url_hash等
   server minio-01.example.com:9000;
   server minio-02.example.com:9000;
}

upstream minio_web {
   least_conn;
   server minio-01.example.com:9001;
   server minio-02.example.com:9001;
}

server {
   listen       80;
   listen  [::]:80;
   server_name  192.168.182.134;

   # Allow special characters in headers
   ignore_invalid_headers off;
   # Allow any size file to be uploaded.
   # Set to a value such as 1000m; to restrict file size to a specific value
   client_max_body_size 0;
   # Disable buffering
   proxy_buffering off;
   proxy_request_buffering off;

   location / {
      proxy_set_header Host $http_host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $scheme;

      proxy_connect_timeout 300;
      # Default is HTTP/1, keepalive is only enabled in HTTP/1.1
      proxy_http_version 1.1;
      proxy_set_header Connection "";
      chunked_transfer_encoding off;

      proxy_pass http://minio_api; # 用于反向代理
   }

   location /minio/ui/ {
      rewrite ^/minio/ui/(.*) /$1 break;
      proxy_set_header Host $http_host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $scheme;
      proxy_set_header X-NginX-Proxy true;

      # This is necessary to pass the correct IP to be hashed
      real_ip_header X-Real-IP;

      proxy_connect_timeout 300;

      # To support websockets in MinIO versions released after January 2023
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
      # Some environments may encounter CORS errors (Kubernetes + Nginx Ingress)
      # Uncomment the following line to set the Origin request to an empty string
      # proxy_set_header Origin '';

      chunked_transfer_encoding off;

      proxy_pass http://minio_web; # 用于反向代理
   }
}

检查nginx配置文件是否配置正确

nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

重新加载nginx配置文件

nginx -s reload

配置minio环境变量

nano /etc/default/minio

在环境变量中添加MINIO_BROWSER_REDIRECT_URL关键字，用于浏览器重定向

...此处省略...
MINIO_BROWSER_REDIRECT_URL="http://192.168.182.134/minio/ui"

192.168.182.134，属于nginx所在地址

/minio/ui与nginx配置文件中的location /minio/ui/命名方式保持一致

采用http://192.168.182.134/minio/ui地址登录Google Chrome浏览器
