Installing Netdata on CentOS 7

Netdata is a distributed, real-time performance and health monitoring system. This guide demonstrates how to install Netdata on a Vultr CentOS 7 server instance.

Prerequisites

Before proceeding with this guide, make sure:

• You have a freshly deployed CentOS 7 server instance.

• The software packages are up-to-date.

• You are connected via SSH as a non-root user with sudo privileges.

The IP address 192.0.2.123 is an example.

1. Install Dependencies

To install Netdata, you need to install the dependencies below:

$ sudo yum install zlib-devel libuuid-devel libmnl-devel gcc make git autoconf autogen automake pkgconfig

$ sudo yum install curl jq nodejs

2. Install Netdata

Install Netdata with the official installation script:

1. Make sure you run bash for your shell

   $ bash
   

2. Install Netdata directly from GitHub source

   $ bash <(curl -Ss https://my-netdata.io/kickstart.sh)
   

If no errors occur during installation, the Netdata daemon will start.

3. Modify Firewall Rules

Before you can access Netdata's web interface, you need to modify firewall rules to allow traffic on port 19999, the default communication port of Netdata:

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

$ sudo firewall-cmd --reload

4. View the monitoring interface

Confirm the installation by opening your web browser and visiting the monitoring interface of Netdata at http://192.0.2.123:19999

5. Setup Systemd Service Unit

For convenience, put Netdata under the control of systemd:

$ sudo yum install psmisc

$ sudo killall netdata

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

$ sudo systemctl daemon-reload

$ sudo systemctl start netdata.service

$ sudo systemctl enable netdata.service

To further configure Netdata, edit the configuration file:

$ sudo vi /etc/netdata/netdata.conf

You can also view the current configuration at http://192.0.2.123:19999/netdata.conf
