Grafana provides powerful visualization tools for monitoring metrics. In this guide, I\u2019ll show you how to set up Grafana on a Linux server without Docker, using a lightweight configuration with SQLite as the default database.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\n\n\n\n

1. Add the Grafana Repository<\/h2>\n\n\n\n

To install Grafana from its official repository, start by adding it to your APT sources.<\/p>\n\n\n\n

Create a new APT source file for Grafana<\/strong>:<\/p>\n\n\n\n

sudo vi \/etc\/apt\/sources.list.d\/grafana.list<\/pre>\n\n\n\n
Add the following line and save the file<\/strong>:<\/p>\n\n\n\n
deb [signed-by=\/usr\/share\/keyrings\/grafana-archive-keyring.gpg] https:\/\/packages.grafana.com\/oss\/deb stable main<\/pre>\n\n\n\n
Add Grafana\u2019s GPG Key:<\/strong> <\/p>\n\n\n\n
Import the GPG key to ensure that the repository is trusted.<\/p>\n\n\n\n
curl https:\/\/packages.grafana.com\/gpg.key | sudo gpg --dearmor -o \/usr\/share\/keyrings\/grafana-archive-keyring.gpg<\/pre>\n\n\n\n
Update the package list:<\/strong> <\/p>\n\n\n\n
Refresh APT to include the new Grafana repository.<\/p>\n\n\n\n
sudo apt-get update<\/pre>\n\n\n\n
2. Install SQLite (If Not Installed)<\/h2>\n\n\n\n
Grafana uses SQLite by default for data storage on single-server setups. Let\u2019s ensure SQLite is installed.<\/p>\n\n\n\n
Check if SQLite is installed:<\/strong><\/p>\n\n\n\n
sqlite3 --version<\/pre>\n\n\n\n
If you see a version number, you can skip to the next step. <\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
If not, install SQLite with the command below.<\/p>\n\n\n\n
Install SQLite:<\/strong><\/p>\n\n\n\n
sudo apt-get install sqlite3 -y<\/pre>\n\n\n\n
3. Install Grafana<\/h2>\n\n\n\n
With the repository and SQLite ready, you can now install Grafana.<\/p>\n\n\n\n
sudo apt-get install grafana -y<\/pre>\n\n\n\n
4. Start and Enable Grafana<\/h2>\n\n\n\n
Start Grafana and enable it to run automatically at system startup.<\/p>\n\n\n\n
sudo systemctl start grafana-server\nsudo systemctl enable grafana-server<\/pre>\n\n\n\n
5. Configure Grafana to Use SQLite (Optional)<\/h2>\n\n\n\n
Grafana uses SQLite by default, but you can verify this configuration in the grafana.ini<\/code> file.<\/p>\n\n\n\n
Open the configuration file:<\/strong><\/p>\n\n\n\n
sudo vi \/etc\/grafana\/grafana.ini<\/pre>\n\n\n\n
Locate the [database]<\/code> section<\/strong>, and confirm it uses SQLite by setting the following option (remove any semicolon ;<\/code> at the beginning to uncomment the line):<\/p>\n\n\n\n
[database]\ntype = sqlite3<\/pre>\n\n\n\n
You can leave other parameters like host<\/code>, name<\/code>, user<\/code>, and password<\/code> commented out, as they are only required for MySQL or PostgreSQL.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Save and exit the file,<\/strong> and restart Grafana for any changes to take effect:<\/p>\n\n\n\n
sudo systemctl restart grafana-server<\/pre>\n\n\n\n
6. Access Grafana in Your Browser<\/h2>\n\n\n\n
Visit http:\/\/your-server-ip:3000<\/code> in your web browser. The default login credentials are:<\/p>\n\n\n\n
Username: admin\nPassword: admin<\/pre>\n\n\n\n
On the first login, you\u2019ll be prompted to change the password for security.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
7. Secure the Connection with HTTPS<\/h2>\n\n\n\n
You can follow Step 4 in the post below to enable HTTPS with Certbot and set up a reverse proxy for the Grafana service.<\/p>\n\n\n\n
