Here you can access the Netdata dashboard on AlmaLinux by typing your server’s IP address in your web browser followed by 19999:

http://server-ip-address:19999/

You will your system overview on the Netdata dashboard:

That’s it, you are done.

For more information, you can visit the Netdata Documentation page.

Alternative Installation Methods for Netdata on AlmaLinux 9

While the above method of installing Netdata from the GitHub repository is functional, it requires a bit more manual configuration and dependency management. Let’s explore two alternative approaches to Install Netdata on AlmaLinux 9: using the Netdata package repository and using Docker.

1. Installing Netdata using the Netdata Package Repository

Netdata provides its own package repository, which simplifies the installation and update process. This method is generally recommended as it ensures you’re getting the latest stable version of Netdata and handles dependency management automatically.

Steps:

1. Add the Netdata Repository:

   Create a new repository file for Netdata.

   sudo nano /etc/yum.repos.d/netdata.repo

   Add the following content to the file:

   [netdata]
   name=Netdata
   baseurl=https://packagecloud.io/netdata/netdata/el/9/$basearch
   repo_gpgcheck=1
   gpgcheck=0
   enabled=1
   gpgkey=https://packagecloud.io/netdata/netdata/gpgkey
   sslverify=1
   sslcacert=/etc/pki/tls/certs/ca-bundle.crt
   metadata_expire=300

   Note: The el/9 part of the baseurl is crucial for AlmaLinux 9.

2. Install Netdata:

   Now that the repository is configured, you can install Netdata using dnf:

   sudo dnf install netdata -y

3. Start and Enable Netdata:

   Similar to the previous method, start and enable the Netdata service:

   sudo systemctl start netdata
   sudo systemctl enable netdata

4. Verify Netdata Status:

   Confirm that Netdata is running:

   sudo systemctl status netdata

5. Configure Firewall:

   Allow traffic to port 19999:

   sudo firewall-cmd --permanent --add-port=19999/tcp
   sudo firewall-cmd --reload

This approach automates dependency resolution and provides a more streamlined installation experience for Install Netdata on AlmaLinux 9. Updates can be managed through dnf update along with the rest of your system packages.

2. Installing Netdata using Docker

Docker provides a containerized environment, isolating Netdata from the host system and simplifying deployment. This method is especially useful for managing multiple Netdata instances or when you want to avoid conflicts with existing system packages.

Prerequisites:

• Docker and Docker Compose must be installed on your AlmaLinux 9 system. If not, install them:

  sudo dnf install docker -y
  sudo systemctl start docker
  sudo systemctl enable docker
  sudo dnf install docker-compose -y

Steps:

1. Create a docker-compose.yml file:

   Create a directory for your Docker Compose configuration:

   mkdir netdata-docker
   cd netdata-docker
   nano docker-compose.yml

   Add the following content to the docker-compose.yml file:

   version: '3.8'
   services:
     netdata:
       image: netdata/netdata
       container_name: netdata
       ports:
         - "19999:19999"
       cap_add:
         - SYS_PTRACE
       security_opt:
         - apparmor=unconfined
       volumes:
         - netdataconfig:/etc/netdata
         - netdatalib:/var/lib/netdata
         - /proc:/host/proc:ro
         - /sys:/host/sys:ro
         - /etc/passwd:/host/etc/passwd:ro
         - /etc/group:/host/etc/group:ro
       restart: unless-stopped
   
   volumes:
     netdataconfig:
     netdatalib:

   Explanation:

   • image: netdata/netdata: Specifies the official Netdata Docker image.
   • ports: - "19999:19999": Maps port 19999 on the host to port 19999 in the container.
   • cap_add: - SYS_PTRACE: Grants the container the SYS_PTRACE capability, which is required for some Netdata collectors.
   • security_opt: - apparmor=unconfined: Disables AppArmor confinement for the container (may be necessary depending on your AppArmor configuration). Use with caution and consider creating a custom AppArmor profile for more security.
   • volumes: Mounts several host directories into the container for Netdata to collect metrics. The ro flag makes the /proc, /sys, /etc/passwd and /etc/group volumes read-only.
   • restart: unless-stopped: Automatically restarts the container unless it’s explicitly stopped.

2. Start the Netdata Container:

   Run the following command in the netdata-docker directory:

   docker-compose up -d

   This will download the Netdata image (if it’s not already present) and start the container in detached mode.

3. Access the Netdata Dashboard:

   Open your web browser and navigate to http://server-ip-address:19999/.

The Docker method offers a portable and isolated way to run Netdata. It simplifies updates (by pulling a new image) and allows you to easily deploy Netdata on different systems without worrying about compatibility issues. To Install Netdata on AlmaLinux 9 using Docker is a robust choice.

By exploring these alternative installation methods, you can choose the approach that best suits your specific needs and environment for Install Netdata on AlmaLinux 9. The package repository method offers a streamlined experience with automatic dependency management, while the Docker method provides isolation and portability.
