Install NGINX and Configure for MLflow

Set up NGINX as a reverse proxy to route secure external traffic to your MLflow server.

Prerequisites

Linux-based server (RHEL/CentOS or Ubuntu/Debian)
Root or sudo privileges
MLflow server running on port 5000
SSL certificate and private key files (e.g., cert.pem and key.pem)

Steps to install

Install Nginx: Choose the appropriate command based on your Linux distribution.

For RHEL/CentOS:

sudo yum install -y nginx

For Ubuntu/Debian:

sudo apt install -y nginx

Configure the NGINX main file (/etc/nginx/nginx.conf)

Info

Use the following NGINX configuration to set up a reverse proxy with performance optimizations:

cat _etc_nginx_nginx.conf # For more information on configuration, see: # * Official English Documentation: http:__nginx.org_en_docs_ # * Official Russian Documentation: http:__nginx.org_ru_docs_ user nginx; worker_processes auto; error_log _var_log_nginx_error.log; pid _run_nginx.pid; # Load dynamic modules.

Configure reverse proxy for MLflow (/etc/nginx/conf.d/mlflow.conf)

This configuration:

Redirects all HTTP traffic to HTTPS
Proxies HTTPS requests securely to the MLflow server

cat _etc_nginx_conf.d_mlflow.conf # Redirect all HTTP requests to HTTPS server { listen 80; server_name 10.100.11.26; location _ { return 301 https:__$host$request_uri; } } # Main SSL-secured MLflow server block server { listen 443 ssl; server_name mlflow.yourdomain.com; ssl_certificate _usr_odp_3.3.6.2-1006_mlflow_cert.pem; ssl_certificate_key _usr_odp_3.3.6.2-1006_mlflow_key.pem; ssl_session_cache shared:SSL:10m; ssl_session_timeout 10m; ssl_protocols TLSv1.2 TLSv1.3; ssl_ciphers HIGH:!aNULL:!MD5; location _ { proxy_pass http:__10.100.11.26:5000; proxy_set_header Host $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; } }

Note:

Replace mlflow.yourdomain.com with your actual domain or public IP.
Update SSL certificate paths to match your environment.
Replace 10.100.11.26:5000 with your MLflow backend server address and port.

Start and enable Nginx.

sudo systemctl start nginx sudo systemctl enable nginx

To verify Nginx is running:

sudo systemctl status nginx

Reload the configuration after any change.

sudo nginx -t # Validate config sudo systemctl reload nginx
