Loki Installation
Grafana is only for viewing Dashboard. Loki has to be installed in the same system in order to feed the logs into grafana.
The following steps are used for Loki setup,
- 1.The following script is used in the installation https://gitlab.com/PBSA/tools-libs/infrastructure/devops-misc-issues/-/blob/main/scripts/loki/loki-install.sh
#!/bin/bash
echo "Updating System & Installing Dependencies"
sudo apt update && sudo apt dist-upgrade -y
sudo apt install unzip -y
echo "Creating /etc/loki"
mkdir /etc/loki
cd /etc/loki
echo "Fetching Loki version 2.6.1"
curl -O -L "https://github.com/grafana/loki/releases/download/v2.6.1/loki-linux-amd64.zip"
# extract the binary
unzip "loki-linux-amd64.zip"
#make sure it is executable
chmod a+x "loki-linux-amd64"
sudo cp loki-linux-amd64 /usr/local/bin/loki
echo "Adding config.yaml"
sudo tee /etc/loki/config.yaml<<EOF

echo "Enabling loki on startup, and starting the service"
sudo systemctl daemon-reload
sudo systemctl enable loki.service
sudo systemctl start loki.service
sudo systemctl status loki.service
2. Copy and paste the above script into a file name:
loki-install.sh3. Run the script with below CLI,
sudo sh loki-install.sh
If the deployment is running on a cloud/remote, the following document can be use to configure an nginx proxy.
