prometheus 服务端部署

创建服务

vi /etc/systemd/system/prometheus.service

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

[Service]
Restart=on-failure
ExecStart=/opt/prom/prometheus-2.37.1.linux-amd64/prometheus --config.file=/opt/prom/prometheus-2.37.1.linux-amd64/prometheus.yml --web.listen-address=:9090 --web.enable-lifecycle

[Install]
WantedBy=multi-user.target

--web.enable-lifecycle 开启配置文件热加载，开启后修改 prometheus.yml 配置文件后不用重启 prometheus 服务，支持两种方式重新加载配置文件：

1、kill -HUP $(pidof prometheus)

2、curl -XPOST http://192.168.50.4:9090/-/reload

启动服务

systemctl daemon-reload
systemctl enable prometheus
systemctl start prometheus

执行 netstat 命令查看端口是否启动

netstat -nltup | grep 9090

浏览器访问：http://192.168.50.4:9090/

prometheus 推送网关部署

创建服务

vi /etc/systemd/system/pushgateway.service

[Unit]
Description=Prometheus Pushgateway
Documentation=https://prometheus.io/docs/instrumenting/pushing/
After=network-online.target

[Service]
Restart=on-failure
ExecStart=/opt/prom/pushgateway-1.4.3.linux-amd64/pushgateway --web.listen-address=:9091

[Install]
WantedBy=multi-user.target

启动服务

systemctl daemon-reload
systemctl enable pushgateway
systemctl start pushgateway

配置推送网关

编辑 prometheus.yml 文件，在 scrape_configs 配置下新增一个 job

  - job_name: "push-metrics"
    static_configs:
      - targets: ["192.168.50.4:9091"]

重新载入配置

kill -HUP $(pidof prometheus)

prometheus 节点导出器部署

创建服务

vi /etc/systemd/system/node_exporter.service

[Unit]
Description=Prometheus node_exporter
Documentation=https://prometheus.io/docs/instrumenting/exporters/
After=network.target

[Service]
Restart=on-failure
ExecStart=/opt/prom/node_exporter-1.3.1.linux-amd64/node_exporter --web.listen-address=:9100

[Install]
WantedBy=multi-user.target

启动服务

systemctl daemon-reload
systemctl enable node_exporter
systemctl start node_exporter

执行 netstat 命令查看端口是否启动

netstat -nltup | grep 9100

浏览器访问：http://192.168.50.4:9100/metrics

导出器配置

编辑 prometheus.yml 文件，在 scrape_configs 配置下新增一个 job

  - job_name: "192.168.50.4"
    static_configs:
      - targets: ["192.168.50.4:9100"]

重新载入配置

kill -HUP $(pidof prometheus)

prometheus 告警管理器部署

创建服务

vi /etc/systemd/system/alertmanager.service

[Unit]
Description=Prometheus Alertmanager
Documentation=https://prometheus.io/docs/alerting/latest/overview/
After=network-online.target

[Service]
Restart=on-failure
ExecStart=/opt/prom/alertmanager-0.24.0.linux-amd64/alertmanager --config.file=/opt/prom/alertmanager-0.24.0.linux-amd64/alertmanager.yml --web.listen-address=:9093

[Install]
WantedBy=multi-user.target

启动服务

systemctl daemon-reload
systemctl enable alertmanager
systemctl start alertmanager

执行 netstat 命令查看端口是否启动

netstat -nltup | grep 9093

浏览器访问：http://192.168.50.4:9093/

配置告警

将 prometheus.yml 文件的告警配置修改为如下内容：

alerting:
  alertmanagers:
    - static_configs:
        - targets:
          - 192.168.50.4:9093

重新载入配置

kill -HUP $(pidof prometheus)

Grafana 部署

创建服务

vi /etc/systemd/system/grafana.service

[Unit]
Description=Grafana Server
Documentation=https://grafana.com/docs/
After=network-online.target

[Service]
Restart=on-failure
ExecStart=/opt/prom/grafana-9.1.5/bin/grafana-server --homepath /opt/prom/grafana-9.1.5 --config /opt/prom/grafana-9.1.5/conf/defaults.ini

[Install]
WantedBy=multi-user.target

通过 defaults.ini 配置文件中的 http_port 修改服务端口号，注释时使用英文分号，即 ;

启动服务

systemctl daemon-reload
systemctl enable grafana
systemctl start grafana

执行 netstat 命令查看端口是否启动

netstat -nltup | grep 3000

浏览器访问：http://192.168.50.4:3000/
