Ubantu安装Prometheus、Grafana、node_exporter、elasticsearch_exporter监 ...

Prometheus安装

更新体系包索引：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
上传并解压
修改prometheus.yml

1. scrape_configs:
2.   # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
3.   - job_name: "prometheus"
5.     # metrics_path defaults to '/metrics'
6.     # scheme defaults to 'http'.
8.     static_configs:
9.       - targets: ["localhost:9090"]
11.   - job_name: 'elasticsearch' # 监控ElasticSearch的job名称，自定义即可
12.     scrape_interval: 60s
13.     scrape_timeout:  30s
14.     metrics_path: "/metrics" # 监控后缀
15.     static_configs:
16.     - targets: ["192.168.xxx.xxx:9114"] # 刚刚配置的elasticsearch_exporter监控地址
18.   - job_name: 'Linux'
19.     scrape_interval: 60s
20.     scrape_timeout:  30s
21.     metrics_path: "/metrics"
22.     static_configs:
23.     - targets: ["192.168.xxx.xxx:9100"]

复制代码

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

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

复制代码

验证：http:ip:9090 点击targets
设置快速启动：

1. vim /etc/systemd/system/prometheus .service

复制代码

1. [Unit]
2. Requires=network.target
3. After=network.target
5. [Service]
6. Type=simple
7. WorkingDirectory=/usr/local/prometheus
8. ExecStart=/usr/local/prometheus/prometheus --log.level=info
9. TimeoutSec=30
10. Restart=always
12. [Install]
13. WantedBy=multi-user.target

复制代码

1. systemctl daemon-reload
2. systemctl start prometheus.service
3. systemctl status prometheus.service

Grafana安装

直接官网安装：Grafana安装
验证：http:ip:3000 默认账号暗码：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）并保存设置。
