[Debian] Debian 10.9 (Buster) 安裝 新版 普羅米修斯(prometheus) + node_exporter + Grafana

 

#Step 01 – 基本安裝

Step A : Create Prometheus system user / group

sudo groupadd --system prometheus
sudo useradd -s /sbin/nologin --system -g prometheus prometheus

Step B: Create configuration and data directories

sudo mkdir /var/lib/prometheus
for i in rules rules.d files_sd; do sudo mkdir -p /etc/prometheus/${i}; done

Step C: Download and Install Prometheus on Debian 10 (Buster)

# 一般來說 wget 已經安裝可省略
# sudo apt-get -y install wget
mkdir -p /tmp/prometheus && cd /tmp/prometheus
curl -s https://api.github.com/repos/prometheus/prometheus/releases/latest \
  | grep browser_download_url \
  | grep linux-amd64 \
  | cut -d '"' -f 4 \
  | wget -qi -

# 解壓縮檔案

tar xvf prometheus*.tar.gz
cd prometheus*/

sudo mv prometheus promtool /usr/local/bin/

sudo mv prometheus.yml  /etc/prometheus/prometheus.yml

sudo mv consoles/ console_libraries/ /etc/prometheus/
cd ~/
rm -rf /tmp/prometheus

sudo vi /etc/prometheus/prometheus.yml

#############################################################################
# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['localhost:9090']
#############################################################################

Step D: Create a Prometheus systemd Service unit file

##########################################################
sudo tee /etc/systemd/system/prometheus.service<>

for i in rules rules.d files_sd; do sudo chown -R prometheus:prometheus /etc/prometheus/${i}; done
for i in rules rules.d files_sd; do sudo chmod -R 775 /etc/prometheus/${i}; done
sudo chown -R prometheus:prometheus /var/lib/prometheus/

重啟服務
sudo systemctl daemon-reload
sudo systemctl start prometheus
sudo systemctl enable prometheus

$  systemctl status prometheus

http://[ip_hostname]:9090.

Step E: Install node_exporter on Debian 10 Buster

curl -s https://api.github.com/repos/prometheus/node_exporter/releases/latest \
| grep browser_download_url \
| grep linux-amd64 \
| cut -d '"' -f 4 \
| wget -qi -

tar -xvf node_exporter*.tar.gz
cd  node_exporter*/
sudo cp node_exporter /usr/local/bin
# 確認版本
$ node_exporter --version

設定啟動服務

sudo tee /etc/systemd/system/node_exporter.service <>

sudo systemctl daemon-reload
sudo systemctl start node_exporter
sudo systemctl enable node_exporter

$  systemctl status node_exporter.service 

#將服務監控加入普羅米修斯
sudo vi /etc/prometheus/prometheus.yml

- job_name: 'node_exporter'
  static_configs:
  - targets: ['localhost:9100']

sudo systemctl restart prometheus

 

#Step 02 – 安裝Grafana

#$ echo deb http://nginx.org/packages/debian/ stretch nginx | sudo tee /etc/apt/sources.list.d/nginx.list
$ echo "deb http://nginx.org/packages/mainline/debian `lsb_release -cs` nginx" | sudo tee /etc/apt/sources.list.d/nginx.list
$ wget http://nginx.org/keys/nginx_signing.key && sudo apt-key add nginx_signing.key 
$ sudo apt update && apt install nginx -y

需要注意的是，這一步安裝的 Nginx 和系統自帶的 nginx 的配置目錄略有區別，可以用一下幾個簡單的命令修正：
讓設定習慣不用改變
sudo mkdir /etc/nginx/{sites-available,sites-enabled}
sudo mv /etc/nginx/conf.d/* /etc/nginx/sites-available
sudo rmdir -f /etc/nginx/conf.d/
sudo perl -pi -e 's/conf.d/sites-enabled/g' /etc/nginx/nginx.conf

要設定一下設定檔連結
ln -s /etc/nginx/sites-available/default.conf /etc/nginx/sites-enabled/

mkdir -p /var/www/html

chown -R nginx:nginx /var/www/html

檢查 nginx 設定檔是否正確

nginx -t

重新啟動 nginx 並 設定開機啟動

systemctl restart nginx 
systemctl enable nginx 

 

#Step 03 –

sudo apt install -y adduser libfontconfig1
wget https://dl.grafana.com/oss/release/grafana_8.0.5_amd64.deb
sudo dpkg -i grafana_8.0.5_amd64.deb

systemctl daemon-reload
systemctl start grafana-server
systemctl enable grafana-server.service
