一、Prometheus安装

tar -zxvf prometheus-2.44.0.linux-amd64.tar.gz -C /opt/module/
sudo chown -R bigdata:bigdata /opt/module/prometheus-2.44.0.linux-amd64
mv /opt/module/prometheus-2.44.0.linux-amd64 /opt/module/prometheus-2.44.0
ln -s /opt/module/prometheus-2.44.0 /usr/local/prometheus

1.1 修改配置文件

vim /opt/module/prometheus-2.44.0/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=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"

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

    static_configs:
      - targets: ["node1:9090"]

  - job_name: 'pushgateway'
    static_configs:
    - targets: ["node1:9091"]
      labels:
        instance: pushgateway

  - job_name: 'node exporter'
    static_configs:
    - targets: ['node1:9100', 'node2:9100', 'node3:9100', 'node4:9100']

  - job_name: 'kafka_exporter'
    static_configs:
    - targets: ["node1:9308"]

  - job_name: 'clickhouse-cluster'
    static_configs:
    - targets: ['node4:9363','node3:9363','node2:9363','node1:9363']

1.2 创建数据目录

mkdir -p /data/prometheus/data
chown -R bigdata:bigdata /data/prometheus

1.3 使用systemctl管理Prometheus

sudo vim /usr/lib/systemd/system/prometheus.service

[Unit]
Description=prometheus
Documentation=https://prometheus.io/docs/introduction/overview/After=network.target
After=network.target

[Service]
Type=simple
User=bigdata
Group=bigdata
Restart=on-failure
WorkingDirectory=/usr/local/prometheus/
ExecStart=/usr/local/prometheus/prometheus --web.enable-admin-api --web.enable-lifecycle --config.file=/usr/local/prometheus/prometheus.yml --storage.tsdb.path=/data/prometheus/data
[Install]
WantedBy=multi-user.target

命令

systemctl start prometheus
systemctl enable prometheus
systemctl status prometheus

1.4 pushgateway部署

tar -zxvf /opt/software/pushgateway-1.6.0.linux-amd64.tar.gz -C /opt/module/
sudo chown -R bigdata:bigdata /opt/module/pushgateway-1.6.0.linux-amd64
sudo mv /opt/module/pushgateway-1.6.0.linux-amd64 /opt/module/pushgateway-1.6.0

修改配置文件

sudo vim /usr/lib/systemd/system/pushgateway.service

[Unit]
Description=pushgateway
Wants=prometheus.service
After=prometheus.service

[Service]
Type=simple
User=bigdata
Group=bigdata
Restart=on-failure
