Easily Install Netdata on Rocky Linux 9 – OrcaCore

In this tutorial, we will guide you on How To Install Netdata on Rocky Linux 9. Netdata is a distributed, real-time, performance and health monitoring tool for systems and applications. It functions as a highly optimized monitoring agent that you install on all your systems and containers.

Netdata offers unparalleled insights, in real-time, into everything happening on the systems it monitors (including web servers, databases, and applications), presenting this information through highly interactive web dashboards. It can operate autonomously, without relying on any third-party components, or it can be seamlessly integrated into existing monitoring toolchains.

Netdata is designed for speed and efficiency, allowing it to run continuously on all systems (physical & virtual servers, containers, IoT devices) without disrupting their core functionality.

Netdata is free, open-source software, and it currently supports Linux, FreeBSD, and macOS.

Now, let’s follow the steps below, as provided by Orcacore, to Install Netdata on Rocky Linux 9.

Alternative Installation Methods for Netdata on Rocky Linux 9

While the previous method details installing Netdata from the GitHub repository, here are two alternative approaches you can use to achieve the same result on Rocky Linux 9.

1. Using the Netdata Static Binary Installer

This method uses a pre-compiled binary installer, simplifying the installation process. It’s a faster method than compiling from source.

Explanation:

Netdata provides a script that automatically downloads and installs the latest stable version of Netdata using a pre-built binary. This eliminates the need to clone the repository, install dependencies, and compile the source code. This method is suitable for users who prefer a simpler and faster installation process.

Steps:

1. Download and Run the Installer:

   curl -Ss 'https://install-netdata.sh' | sudo bash

   This command downloads the install-netdata.sh script and executes it with root privileges using sudo bash. The script will handle downloading the binary, installing Netdata, and configuring the systemd service.

2. Follow the Prompts:

   The script will prompt you for confirmation before proceeding. Answer ‘yes’ to the prompts to continue the installation.

3. Verify Installation:

   After the installation is complete, verify that Netdata is running:

   sudo systemctl status netdata

4. Configure the Firewall:

   As with the original method, you’ll need to open port 19999 in your firewall:

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

5. Access the Dashboard:

   Access the Netdata dashboard in your web browser using your server’s IP address and port 19999.

Pros:

• Simpler and faster than compiling from source.
• No need to install dependencies manually.
• Automatic updates (if configured).

Cons:

• Less control over the build process.
• Relies on the availability of the binary on Netdata’s servers.

2. Using a Container (Docker/Podman)

This method involves running Netdata within a container. It’s a good option for isolating Netdata from the host system and simplifying deployment.

Explanation:

Containers provide an isolated environment for running applications. Running Netdata in a container ensures that its dependencies do not conflict with other software installed on the host system. This method also simplifies deployment and management, as you can easily deploy and update Netdata using container orchestration tools.

Steps (using Docker – the process is similar for Podman):

1. Install Docker:

   If you don’t have Docker installed, install it using the following command:

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

2. Pull the Netdata Image:

   Download the official Netdata Docker image from Docker Hub:

   sudo docker pull netdata/netdata

3. Run the Netdata Container:

   Run the Netdata container with the necessary volumes and ports:

   sudo docker run -d --name=netdata 
       --cap-add SYS_PTRACE 
       --security-opt apparmor=unconfined 
       -v netdataconfig:/etc/netdata 
       -v netdatalib:/var/lib/netdata 
       -v netdatacache:/var/cache/netdata 
       -v /:/host:ro,rslave 
       -p 19999:19999 
       --restart unless-stopped 
       netdata/netdata

   Explanation of the parameters:

   • -d: Runs the container in detached mode (background).
   • --name=netdata: Assigns the name "netdata" to 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, which may be necessary for some systems.
   • -v netdataconfig:/etc/netdata: Mounts a Docker volume named netdataconfig to the container’s /etc/netdata directory for persistent configuration.
   • -v netdatalib:/var/lib/netdata: Mounts a Docker volume named netdatalib to the container’s /var/lib/netdata directory for persistent data.
   • -v netdatacache:/var/cache/netdata: Mounts a Docker volume named netdatacache to the container’s /var/cache/netdata directory for persistent cache.
   • -v /:/host:ro,rslave: Mounts the host’s root filesystem to the container’s /host directory in read-only mode. This allows Netdata to collect metrics from the host system. rslave ensures propagation of mount and unmount events.
   • -p 19999:19999: Maps port 19999 on the host to port 19999 in the container.
   • --restart unless-stopped: Restarts the container automatically unless it is explicitly stopped.
   • netdata/netdata: Specifies the Docker image to use.

4. Verify Container is Running:

   sudo docker ps

   This command will list running Docker containers. You should see the netdata/netdata container in the list.

5. Configure the Firewall:

   As with the original method, you’ll need to open port 19999 in your firewall:

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

6. Access the Dashboard:

   Access the Netdata dashboard in your web browser using your server’s IP address and port 19999.

Pros:

• Isolation from the host system.
• Simplified deployment and management.
• Consistent environment across different systems.

Cons:

• Requires Docker or Podman to be installed.
• Slightly more complex configuration than the binary installer.
• Increased resource usage compared to running Netdata directly on the host.

These alternative methods offer different approaches to Install Netdata on Rocky Linux 9, allowing you to choose the method that best suits your needs and environment. Regardless of the chosen method, Netdata provides invaluable real-time insights into your system’s performance and health.
