Learn How to Install and Run Netdata on AlmaLinux VPS! This article provides a step-by-step guide detailing how to install and run Netdata on AlmaLinux VPS—a powerful, real-time performance monitoring tool for systems and applications. ✅ What is Netdata? Netdata is an open-source monitoring agent that provides real-time performance metrics for systems, applications, containers, and more—displayed through an interactive web dashboard. It’s lightweight, highly efficient, and ideal for resource monitoring on servers like VPSes. 🛠️ Prerequisites AlmaLinux 8 or AlmaLinux 9 VPS Root or sudo access Internet access Optional: Firewall access if remote monitoring is required How to Install and Run Netdata on AlmaLinux VPS To install and run Netdata on AlmaLinux VPS, follow the steps below: Step-by-Step Installation Guide Update Your System sudo dnf update -y sudo dnf install epel-release -y Install Required Dependencies sudo dnf install git curl gcc make autoconf autogen automake pkgconfig zlib-devel libuuid-devel libmnl-devel cmake libuv-devel libyaml-devel openssl-devel -y Add the Netdata User (Optional but Recommended) sudo useradd -r -U netdata Clone Netdata Installer from GitHub curl https://get.netdata.cloud/kickstart.sh > /tmp/netdata-kickstart.sh && sh /tmp/netdata-kickstart.sh --no-updates --stable-channel --disable-telemetry sudo systemctl enable --now netdata This script installs Netdata and its dependencies automatically. It's safe and the recommended method from the Netdata team. Verify Installation After installation, check that the Netdata service is running: sudo systemctl status netdata Expected output: Active: active (running) If not running, start and enable Netdata: sudo systemctl enable --now netdata Install SSL via Certbot and Nginx Install Nginx and Certbot sudo dnf install nginx -y sudo systemctl enable --now nginx Install Certbot and its Nginx plugin: sudo dnf install epel-release -y sudo dnf install certbot python3-certbot-nginx -y Configure Nginx as Reverse Proxy for Netdata Create Nginx site config for your domain: sudo nano /etc/nginx/conf.d/netdata.conf Paste this (replace monitor.yourdomain.com): server { listen 80; server_name monitor.yourdomain.com; location / { proxy_pass http://127.0.0.1:19999/; proxy_set_header Host $host; proxy_http_version 1.1; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } } Then reload Nginx: sudo nginx -t && sudo systemctl reload nginx Verify by visiting: http://monitor.yourdomain.com Obtain SSL Certificate via Certbot Run Certbot to secure your domain: sudo certbot --nginx -d monitor.yourdomain.com Follow the prompts Certbot will configure SSL and reload Nginx Once complete, visit: https://monitor.yourdomain.com Auto-Renewal (Recommended) Certbot adds automatic renewal via cron or systemd, but you can test it: sudo certbot renew --dry-run Force HTTP to HTTPS Redirection Redirect HTTP to HTTPS Edit the Nginx Netdata config: sudo nano /etc/nginx/conf.d/netdata.conf Update it to include a redirect block: # Redirect all HTTP traffic to HTTPS server { listen 80; server_name monitor.yourdomain.com; return 301 https://$host$request_uri; } # HTTPS block (created by Certbot or manually) server { listen 443 ssl http2; server_name monitor.yourdomain.com; ssl_certificate /etc/letsencrypt/live/monitor.yourdomain.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/monitor.yourdomain.com/privkey.pem; include /etc/letsencrypt/options-ssl-nginx.conf; ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; location / { proxy_pass http://127.0.0.1:19999/; proxy_set_header Host $host; proxy_http_version 1.1; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } } Save and reload Nginx: sudo nginx -t && sudo systemctl reload nginx Update Firewall Rules (Firewalld) Allow HTTP (80) and HTTPS (443): sudo firewall-cmd --permanent --add-servicehttp sudo firewall-cmd --permanent --add-servicehttps sudo firewall-cmd --reload Access Netdata Dashboard By default, Netdata serves on port 19999. To access: http://your-server-ip:19999 Configure Firewall (If Running Firewalld) If firewalld is active, allow port 19999: sudo firewall-cmd --permanent --add-port19999/tcp sudo firewall-cmd --reload Configuring Netdata Edit Main Configuration sudo nano /etc/netdata/netdata.conf Change the bind to directive if you want to expose Netdata to external IPs: bind to 0.0.0.0 After changes, restart Netdata: sudo systemctl restart netdata Enable Basic Authentication (Nginx Proxy) If exposing Netdata publicly, it’s strongly recommended to set up authentication behind a reverse proxy like Nginx or Apache. 📦 Uninstall Netdata sudo /usr/libexec/netdata/netdata-uninstaller.sh --yes 📈 What You Can Monitor with Netdata CPU, memory, disk I/O Network traffic and errors Running processes and resource usage MySQL, Nginx, Apache, Docker, and more via plugins 🧠 Troubleshooting Logs are located at /var/log/netdata/ Configs: /etc/netdata/ Web files: /usr/share/netdata/web/ Now that you know how to install and run Netdata on AlmaLinux VPS, let's learn how to integrate Netdata with Prometheus and Grafana on your AlmaLinux VPS: 🔗 Overview of the Integration Netdata → collects real-time metrics Prometheus → scrapes metrics from Netdata for storage and querying Grafana → visualizes those metrics using queries from Prometheus SEE ALSO: Top 10 Best Grafana Dashboards for Service Monitoring Enable Netdata's Prometheus Exporter Open Netdata's stream.conf and health.d/prometheus.conf: sudo nano /etc/netdata/netdata.conf Find or add the following in the section: enable_prometheus yes prometheus_port 19999 Prometheus can scrape metrics from: http:// :19999/api/v1/allmetrics?formatprometheus Restart Netdata: sudo systemctl restart netdata Install Prometheus on AlmaLinux Create Prometheus User & Directories sudo useradd --no-create-home --shell /bin/false prometheus sudo mkdir /etc/prometheus /var/lib/prometheus Download and Install Prometheus curl -LO https://github.com/prometheus/prometheus/releases/download/v2.52.0/prometheus-2.52.0.linux-amd64.tar.gz tar xvf prometheus-2.52.0.linux-amd64.tar.gz cd prometheus-2.52.0.linux-amd64 sudo cp prometheus promtool /usr/local/bin/ sudo cp -r consoles console_libraries /etc/prometheus/ Configure Prometheus Create or edit /etc/prometheus/prometheus.yml: global: scrape_interval: 15s scrape_configs: - job_name: 'netdata' static_configs: - targets: Create Systemd Service File sudo nano /etc/systemd/system/prometheus.service Paste: DescriptionPrometheus Wantsnetwork-online.target Afternetwork-online.target Userprometheus ExecStart/usr/local/bin/prometheus \ --config.file/etc/prometheus/prometheus.yml \ --storage.tsdb.path/var/lib/prometheus/ \ --web.console.templates/etc/prometheus/consoles \ --web.console.libraries/etc/prometheus/console_libraries WantedBydefault.target Start Prometheus sudo systemctl daemon-reexec sudo systemctl daemon-reload sudo systemctl enable --now prometheus Test it: http:// :9090 Install Grafana on AlmaLinux Add Grafana Repo sudo tee /etc/yum.repos.d/grafana.repo :3000 Default login: Username: admin Password: admin Connect Grafana to Prometheus Log into Grafana Go to Settings > Data Sources > Add data source Choose Prometheus Set URL: http://localhost:9090 Click Save & Test Import Netdata Dashboard Go to Dashboards > Import Use dashboard ID: 1860 (Community Netdata Dashboard) Select Prometheus as data source ✅ Done! You’ve now: Installed and configured Netdata Set up Prometheus to scrape Netdata Connected Grafana to Prometheus Imported Netdata dashboards Conclusion You now know how to install and run Netdata on AlmaLinux VPS. You also know how to integrate Netdata with Prometheus and Grafana.
