Ubantu安装Prometheus、Grafana、node_exporter、elasticsearch_exporter监控运行状态

Prometheus安装

更新系统包索引：apt-get update && apt-get upgrade -y

官网下载Prometheus: Prometheus
命令下载：wget https://github.com/prometheus/prometheus/releases/download/vX.X.X/prometheus-X.X.X.linux-amd64.tar.gz

修改prometheus.yml

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: ["localhost:9090"]

  - job_name: 'elasticsearch' # 监控ElasticSearch的job名称，自定义即可
    scrape_interval: 60s
    scrape_timeout:  30s
    metrics_path: "/metrics" # 监控后缀
    static_configs:
    - targets: ["192.168.xxx.xxx:9114"] # 刚刚配置的elasticsearch_exporter监控地址

  - job_name: 'Linux'
    scrape_interval: 60s
    scrape_timeout:  30s
    metrics_path: "/metrics"
    static_configs:
    - targets: ["192.168.xxx.xxx:9100"]

后台启动：nohup ./prometheus --config.file=prometheus.yml & (注意这里–有两个)
prometheus 默认端口为9090，如果想切换一个端口，可以在启动的时候直接指定，如下：

./prometheus --config.file=prometheus.yml --web.listen-address=:9091 &

验证：http:ip:9090 点击targets

配置快速启动：

vim /etc/systemd/system/prometheus .service

[Unit]
Requires=network.target
After=network.target

[Service]
Type=simple
WorkingDirectory=/usr/local/prometheus 
ExecStart=/usr/local/prometheus/prometheus --log.level=info
TimeoutSec=30
Restart=always

[Install]
WantedBy=multi-user.target

systemctl daemon-reload
systemctl start prometheus.service
systemctl status prometheus.service

Grafana安装

直接官网安装：Grafana安装

验证：http:ip:3000 默认账号密码：admin 不改就点击skip

在Grafana Web界面中，点击“Connections” > “Data Sources”。添加一个新的数据源并选择Prometheus。提供你的Prometheus服务器的URL（例如，http://your_domain:9090）并保存配置。

node_exporter安装

下载地址：node_exporter

上传并解压然后启动: nohup ./node_exporter &

需要重启Prometheus

配置文件是deployment.yml 一般不用改啥

然后启动: nohup ./elasticsearch_exporter &

需要重启Prometheus
