Install Netdata on CentOS 8
Step 1. The first command will update the package lists to ensure you get the latest version and dependencies.
sudo dnf install epel-release sudo dnf update
Step 2. Installing necessary packages for Netdata.
Now install the requisite software packages as shown:
sudo dnf install git zlib-devel libuuid-devel libmnl gcc make git autoconf automake pkgconfig curl findutils
Step 3. Install Netdata on the CentOS system.
Clone the Netdata script installer from the Git repository:
git clone https://github.com/netdata/netdata.git --depth=100
After that, switch to the Netdata directory and execute the below commands so all necessary packages will automatically install on your system:
cd netdata/ ./packaging/installer/install-required-packages.sh --dont-wait --non-interactive netdata
Once done, run the Netdata automated script:
sudo ./netdata-installer.sh
Finally, we need to start and enable Netdata services:
sudo systemctl start netdata sudo systemctl enable netdata sudo systemctl status netdata
Step 4. Configure Firewall.
We need to open this port on the firewall to have access to Netdata via a browser. Now run the commands below:
sudo firewall-cmd --add-port=19999/tcp --permanent sudo firewall-cmd --reload
Step 5. Accessing Netdata Web UI.
Now open the browser http://your_server_ip:19999/ to access the Netdata web interface.
