To deploy Grafana on OVHcloud, you can follow these steps:
- Select and provision a suitable OVHcloud instance to host Grafana. Ensure that you fulfill the system requirements for Grafana installation.
- Connect to your OVHcloud instance using SSH or any remote access method provided by OVHcloud.
- Update the system packages using the package manager. For Ubuntu, use the command: sudo apt update sudo apt upgrade
- Install required dependencies like Git and Node.js. For Ubuntu, use the command: sudo apt install git nodejs
- Clone the Grafana repository from GitHub using the following command: git clone https://github.com/grafana/grafana.git
- Change the directory to the Grafana repository: cd grafana
- Build Grafana using Node.js package manager (npm) by running: npm install
- Once the installation is complete, build the frontend assets using Grunt: npm run build
- Configure Grafana by copying the sample configuration file and making necessary changes: cp conf/sample.ini conf/custom.ini nano conf/custom.ini
- Start the Grafana server using the following command: ./bin/grafana-server
- By default, Grafana listens on port 3000. Access the Grafana web interface by opening a web browser and navigating to your OVHcloud instance's public IP address followed by port 3000 (e.g., http://your_instance_ip:3000).
- Log in to Grafana using the default username and password (admin/admin). It is recommended to change the password and create a new admin user after logging in for the first time.
That's it! You have successfully deployed Grafana on OVHcloud and can now start using it for monitoring and visualizing your data.
