Setup minio storage in Ubuntu with Nginx

Minio Storage :

Minio is an open source object storage server that stores unstructured data such as photos, videos, log files, backups, and container/VM images. It is a lightweight, reliable, and secure alternative to hosting large amounts of data on distributed network drives or in the cloud. Minio is a cloud storage service that offers a simple and cost-effective way to store and serve large amounts of data. It is compatible with Amazon S3 and is ideal for storing and serving large amounts of data for applications such as data lakes, machine learning, analytics, video and audio streaming, web and mobile applications, and more. Minio has features such as server-side encryption, versioning, and secure access control.
Follow the below-mentioned steps to set up MinIO server in Ubuntu machine : 

  1. Download MinIO server and install it.
    wget -O minio.deb

sudo dpkg -i minio.deb

  1. Create the MinIO User, Group, Data Directory, and Environment File.

sudo groupadd -r <minio-user>
Note : Please change minio-user with the username which you want to set for the MinIO console and use the same username at point no.6.

  1. Create the user that the MinIO server will run as.
    sudo useradd -M -r -g <minio-user> <minio-user>
  2. Create the data directory where MinIO will store all its files with the following command:
    sudo mkdir /mnt/data
  3. Give ownership of the data directory to the MinIO user and group:
    sudo chown <minio-user>:<minio-user> /mnt/data
  4. Use the following command to create and open MinIO’s environment file:

sudo nano /etc/default/minio
Provide the below-mentioned details in the MinIO environment file and save it.

MINIO_OPTS=”–certs-dir /home/<user>/.minio/certs –console-address :9001″



Note : Please enter valid machine’s username, MinIO root user and MinIO root password to access MinIO console.

  1. Start the MinIO service :

    Start the MinIO service by running the following command:
    sudo systemctl start minio.service

Check the status of the MinIO service by running the following command:
sudo systemctl status minio.service

Once the MinIO service is in the running state, access the MinIO console with the private IP of the machine <private ip:9001>.

Set up NGINX for the MinIO server :
Nginx (pronounced “engine-x”) is a web server that is used to serve web pages and other content on the World Wide Web. It is an open source web server software that is used to handle high traffic websites due to its scalability and performance. Nginx is noted for its ability to handle multiple simultaneous requests, as well as its speed and low memory usage. It is often used as a reverse proxy, load balancer, and HTTP cache. It can also be used to serve static content such as images, CSS and Javascript files.

To install Nginx, use the following command:
sudo apt update

sudo apt install nginx

Create a directory to place SSL certificates at /etc/nginx:
sudo mkdir certs

Please SSL certificates at /etc/nginx/certs

Configure NGINX file with port 81.

Navigate to /etc/nginx and edit nginx.conf file as mentioned below:

user www-data;
worker_processes auto;
pid /run/;
include /etc/nginx/modules-enabled/*.conf;

events {
        worker_connections 768;
        # multi_accept on;

http {

        # Basic Settings

        sendfile on;

        tcp_nodelay on;

        # server_tokens off;

        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;

        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        # SSL Settings

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
        ssl_prefer_server_ciphers on;

        # Logging Settings

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        # Gzip Settings

        gzip on;

        # gzip_vary on;
        # gzip_proxied any;
        # gzip_comp_level 6;
        # gzip_buffers 16 8k;

        # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

        # Virtual Host Configs

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;
        server {
                listen <PORT> ssl;
                server_name  <MinIO server URL>;
                ssl_certificate      <Path to ssl certificate file>
                ssl_certificate_key  <Path to ssl certificate key>
                ssl_protocols TLSv1.2 TLSv1.3;

         ssl_prefer_server_ciphers on;
        charset utf-8;
                 # To 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;
         # To disable buffering
        proxy_buffering off;

                location / {
                        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 Host $http_host;

                        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://localhost:9000;


#mail {
#       # See sample authentication script at:
#       #
#       # auth_http localhost/auth.php;
#       # pop3_capabilities "TOP" "USER";
#       # imap_capabilities "IMAP4rev1" "UIDPLUS";
#       server {
#               listen     localhost:110;
#               protocol   pop3;
#               proxy      on;
#       }
#       server {
#               listen     localhost:143;
#               protocol   imap;
#               proxy      on;
#       }

Save the changes and restart NGINX.
Now users can use https://server_url:81 as a MinIO server URL.
