# Setting Up Node Exporter
|
|
|
|
## Download Node Exporter
|
|
|
|
Begin by downloading Node Exporter using the wget command:
|
|
|
|
```bash
|
|
wget https://github.com/prometheus/node_exporter/releases/download/v1.7.0/node_exporter-1.7.0.linux-amd64.tar.gz
|
|
```
|
|
|
|
Note: Ensure you are using the latest version of Node Exporter and the correct architecture build for your server. The provided link is for amd64. For the latest releases, check here - Prometheus Node Exporter Releases
|
|
|
|
## Extract the Contents¶
|
|
|
|
After downloading, extract the contents with the following command:
|
|
|
|
```bash
|
|
tar xvf node_exporter-1.7.0.linux-amd64.tar.gz
|
|
```
|
|
|
|
## Move the Node Exporter Binary¶
|
|
|
|
Change to the directory and move the node_exporter binary to /usr/local/bin:
|
|
|
|
```bash
|
|
cd node_exporter-1.7.0.linux-amd64
|
|
```
|
|
|
|
```bash
|
|
sudo cp node_exporter /usr/local/bin
|
|
```
|
|
|
|
Then, clean up by removing the downloaded tar file and its directory:
|
|
|
|
```bash
|
|
rm -rf ./node_exporter-1.7.0.linux-amd64
|
|
```
|
|
|
|
## Create a Node Exporter User¶
|
|
|
|
Create a dedicated user for running Node Exporter:
|
|
```bash
|
|
sudo useradd --no-create-home --shell /bin/false node_exporter
|
|
```
|
|
|
|
Assign ownership permissions of the node_exporter binary to this user:
|
|
```bash
|
|
sudo chown node_exporter:node_exporter /usr/local/bin/node_exporter
|
|
```
|
|
|
|
## Configure the Service¶
|
|
|
|
To ensure Node Exporter automatically starts on server reboot, configure the systemd service:
|
|
|
|
```bash
|
|
sudo nano /etc/systemd/system/node_exporter.service
|
|
```
|
|
|
|
Then, paste the following configuration:
|
|
|
|
```properties
|
|
[Unit]
|
|
Description=Node Exporter
|
|
Wants=network-online.target
|
|
After=network-online.target
|
|
|
|
[Service]
|
|
User=node_exporter
|
|
Group=node_exporter
|
|
Type=simple
|
|
ExecStart=/usr/local/bin/node_exporter
|
|
Restart=always
|
|
RestartSec=3
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
|
|
Save and exit the editor.
|
|
|
|
## Enable and Start the Service¶
|
|
|
|
Reload the systemd daemon:
|
|
|
|
```bash
|
|
sudo systemctl daemon-reload
|
|
```
|
|
|
|
Enable the Node Exporter service:
|
|
```bash
|
|
sudo systemctl enable node_exporter
|
|
```
|
|
|
|
|
|
Start the service:
|
|
|
|
```bash
|
|
sudo systemctl start node_exporter
|
|
```
|
|
|
|
To confirm the service is running properly, check its status:
|
|
|
|
```bash
|
|
sudo systemctl status node_exporter.service
|
|
```
