Tutorial: Deploy Grafana on VPS

In this tutorial, we will guide you through the process of deploying Grafana on a VPS (Virtual Private Server). Grafana is an open-source platform used for data visualization and monitoring. By following these steps, you'll have Grafana up and running in no time.

Step 1: Set up a VPS Firstly, you need to acquire a VPS. You can choose any VPS provider of your preference. Ensure that the VPS meets the system requirements for running Grafana. This typically involves a Linux-based operating system such as Ubuntu, CentOS, or Debian.

Step 2: Connect to the VPS Once you have set up the VPS, connect to it using a secure shell (SSH) client like PuTTY (for Windows) or the Terminal (for macOS or Linux). Use the provided IP address, username, and password to establish the SSH connection.

Step 3: Update and Install Dependencies To begin, update your VPS by running the command:

1

sudo apt update && sudo apt upgrade

Next, install the necessary dependencies such as the NGINX web server, a database (MySQL or PostgreSQL), and other required packages. Each package can be installed using the package manager for your Linux distribution.

Step 4: Download and Install Grafana Visit the official Grafana website and navigate to the downloads section. Obtain the link to the latest stable version of Grafana for your operating system. On the VPS, use the wget command to download Grafana using the obtained link.

Once downloaded, extract the Grafana archive with the command:

1

tar -zxvf <grafana_archive_name.tar.gz>

Step 5: Configure Grafana Navigate into the extracted Grafana directory using the command:

1

cd <grafana_directory>

Inside this directory, locate the conf folder that contains the configuration files. Modify the defaults.ini file to customize Grafana according to your preferences. For instance, you can change the default HTTP port, enable authentication, or define data sources.

Step 6: Start Grafana You can now start Grafana using the command:

1

./bin/grafana-server -homepath .

This will start Grafana on the default port (usually 3000). If you have modified the port in the configuration file, use that port instead.

Step 7: Access Grafana Open a web browser and enter the IP address of your VPS followed by the Grafana port number. For example, http://your-ip-address:3000. You should now see the Grafana login page.

Step 8: Log in to Grafana Use the default username and password (admin/admin) to log in to Grafana for the first time. It is highly recommended to change the default password after logging in.

Congratulations! You have successfully deployed Grafana on your VPS. You can now explore Grafana's features, create dashboards, and connect it to various data sources to visualize and monitor your data.

How to configure data sources in Grafana for monitoring?

To configure data sources in Grafana for monitoring, follow these steps:

1. Open the Grafana web interface by accessing the URL of your Grafana server in a web browser.
2. Login to Grafana using your admin account credentials.
3. Once logged in, click on the "Configuration" button on the left-hand sidebar.
4. In the Configuration menu, click on "Data Sources" under the "Settings" section.
5. On the Data Sources page, click on the green "Add data source" button.
6. Choose the type of data source you want to configure. Grafana supports various types of data sources such as Prometheus, MySQL, InfluxDB, Elasticsearch, etc. Select the appropriate data source based on your monitoring setup.
7. Fill in the required fields for the selected data source type. These fields may vary depending on the type of data source selected. For example, if you are configuring Prometheus, you will need to provide the URL of your Prometheus server.
8. Configure additional optional settings based on your requirements. These settings may include options like basic authentication or TLS/SSL settings.
9. Once you have filled in all the necessary information, click on the "Save & Test" button to test the connection to the data source. If the test is successful, you will see a confirmation message.
10. After saving the data source, you can navigate to the Grafana dashboards and start creating visualizations and panels using the data from your configured data source.

Remember to ensure that your data source is properly configured and accessible before using it for monitoring in Grafana.

How to deploy Grafana on a VPS?

To deploy Grafana on a VPS (Virtual Private Server), you can follow these steps:

1. Choose a VPS provider: Select a VPS provider (such as AWS, DigitalOcean, or Google Cloud) and set up an account.
2. Create a VPS instance: Create a new VPS instance by selecting the desired specifications (CPU, RAM, storage, etc.) and choosing an appropriate operating system (Ubuntu, CentOS, etc.).
3. SSH into your VPS: Connect to your VPS instance using SSH. On a terminal or command prompt, run the following command: ssh username@your_vps_ip_address
4. Update the system: Once connected to the VPS, update the system packages by running these commands: sudo apt update sudo apt upgrade -y
5. Install necessary dependencies: Install dependencies required for running Grafana by running the following command: sudo apt install -y apt-transport-https software-properties-common wget
6. Add the Grafana repository: Add the Grafana repository to the system by running the following command: wget -q -O - https://packages.grafana.com/gpg.key | sudo apt-key add -
7. Add Grafana repository to APT sources list: sudo add-apt-repository "deb https://packages.grafana.com/oss/deb stable main"
8. Update the system again: sudo apt update
9. Install Grafana: Install Grafana by running this command: sudo apt install -y grafana
10. Start and enable Grafana service: sudo systemctl start grafana-server sudo systemctl enable grafana-server
11. Configure firewall rules: Add firewall rules to allow incoming traffic on the Grafana port (default is port 3000). For example, using ufw: sudo ufw allow 3000 sudo ufw enable
12. Access Grafana: Open a web browser and navigate to http://your_vps_ip_address:3000. You should see the Grafana login page.
13. Log in and configure Grafana: Log in with the default username (admin) and password (admin), and follow the on-screen instructions to configure Grafana.
