Overview

VictoriaMetrics is an open-source and fast Prometheus compatible distributed TSDB and query engine. This tutorial will guide you through the installation process of VictoriaMetrics on Debian Linux.

Prerequisites

Before proceeding with the installation, ensure that you have the following prerequisites:

A Debian Linux system
A user account with sudo privileges
A stable internet connection

Step 1: Update your Debian System

Before installing VictoriaMetrics on your system, it is recommended to update your Debian Linux system to the latest version. To update your Debian system, use the following commands:

sudo apt update

Step 2: Install Go

VictoriaMetrics requires Go to be installed on the system. To install Go, follow the below steps:

Download the latest version of Go from the official website. You can download the tar file from the following link:
```
https://golang.org/dl/
```
Extract the downloaded file to the /usr/local directory:
```
sudo tar -C /usr/local -xzf go*.tar.gz
```

Set the environment variables for Go:

echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc
echo 'export GOPATH=$HOME/go' >> ~/.bashrc
echo 'export PATH=$PATH:$GOPATH/bin' >> ~/.bashrc
source ~/.bashrc

Verify the Go installation by running the following command:
```
go version
```
If Go is installed properly, the output should be similar to the following:
```
go version go1.17.2 linux/amd64
```

```
Ensure that you have downloaded the latest release version from the repository.

Extract the downloaded file to the installation directory:

tar -xvf victoria-metrics-*.tar.gz
cd victoria-metrics-*

Run the following command to build VictoriaMetrics:
