Loki is an open-source log aggregation system designed to process and store massive amounts of logs efficiently. In this tutorial, we will walk you through the steps to install Loki on POP! OS Latest.
The first step is to add the Loki repository to your POP! OS system. To do that, you need to create a new file as loki.list in the sources.list.d directory.
Open the terminal by pressing Ctrl+Alt+T and run the following command:
sudo nano /etc/apt/sources.list.d/loki.list
Add the following content into the file:
deb https://packagecloud.io/grafana/loki/ubuntu/ bionic main
Now save the file by pressing Ctrl+O and exit Nano editor by pressing Ctrl+X.
Next, import the GPG key and update the repository cache by running the commands below:
curl https://packagecloud.io/gpg.key | sudo apt-key add -
sudo apt update
At this point, you can easily install Loki using apt-get. Run the following command to install Loki:
sudo apt-get install loki
Hit y and enter when prompted to confirm your installation. It will take a moment to complete the process.
After Loki installation, you need to configure it to collect and process logs. Open the configuration file by running the command:
sudo nano /etc/loki/local-config.yaml
Add the following configuration into the file:
auth_enabled: false
server:
http_listen_port: 3100
ingester:
lifecycler:
address: 127.0.0.1
ring:
kvstore:
store: inmemory
replication_factor: 1
final_sleep: 0s
chunk_idle_period: 5m
chunk_retain_period: 30s
max_transfer_retries: 0

reject_old_samples_max_age: 168h
chunk_store_config:

Save and exit the editor.
Now you can start the Loki service by running the following command:
sudo systemctl start loki
sudo systemctl enable loki
You can also check the status of the service by running:
sudo systemctl status loki
Congratulations, you have successfully installed and configured Loki on your POP! OS system. You can now start sending logs to Loki for processing and storing.
