Netdata is a tool that helps you monitor your server in real-time. It has an easy-to-use web interface and shows live data about CPU, RAM, disk usage, and network bandwidth.

This guide will show you how to install Netdata on CentOS 7.04 servers.

Requirements

1. A CentOS 7.04 server.

2. A non-root user with sudo permissions.

Steps to Install Netdata

Step 1: Update Your System

Start by updating your server to the latest version for security and stability.

 
sudo yum update -y && sudo reboot 
                                    

Step 2: Install Required Tools (Dependencies)

Netdata needs some tools to work. Install them by running:

 
sudo yum install zlib-devel libuuid-devel libmnl-devel gcc make git autoconf autogen automake pkgconfig
sudo yum install curl jq nodejs
                                    

Step 3: Install Netdata

Now, use the official script to install Netdata:

 
cd ~
git clone https://github.com/firehol/netdata.git --depth=1
cd netdata
sudo ./netdata-installer.sh
                                    

During the process, press ENTER when asked.

Step 4: Open Netdata in Your Firewall

Allow traffic on port 19999 so you can access Netdata's web interface:

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

Step 5: Access the Monitoring Interface

After installation, you can check Netdata by opening your browser and visiting:

 
http://<your-server-IP>:19999
                                    

Replace <your-server-IP> with your server's IP address.

Step 6: Set Up a Systemd Service for Netdata

To make managing Netdata easier, configure it to work with systemd:

1. Install a needed package:

   bash Copy

    
   sudo yum install psmisc
                                       

2. Restart Netdata:

   bash Copy

    
   sudo killall netdata
                                       

3. Move the service file:

   bash Copy

    
   sudo cp ~/netdata/system/netdata.service /etc/systemd/system/
                                       

4. Reload and start the service:

   bash Copy

    
   sudo systemctl daemon-reload
   sudo systemctl start netdata.service
   sudo systemctl enable netdata.service
                                       

Edit Netdata Settings

If you need to change Netdata's settings, edit its configuration file:

 
sudo vi /etc/netdata/netdata.conf
                                    

You can view the current settings by visiting this link in your browser:

 
http://<your-server-IP>:19999/netdata.conf
