5分钟快速搭建Prometheus+Grafana监控系统

之前文章介绍了在vue页面内嵌三方监控展示页面grafana，看到里面有主机相关的详细监控信息，有的开发朋友比较感兴趣，问我如何搭建，我这边就介绍一番。

首先简单了解下，prometheus和grafana：

Prometheus是一款开源的监控和报警工具，可以收集和处理时序列数据，常用于监控分布式系统和服务，有自己的promql查询语言。K8s搭配prometheus的组合在企业还是很流行的。

Grafana也是一个开源的数据可视化工具，以查询Prometheus的数据并创建漂亮的监控面板和图表。Prometheus作为数据源,在Grafana中添加Prometheus数据源,就可以创建显示来自Prometheus的metrics数据了。

具体的特性功能大家可以直接上官网查阅，后期我会单独再详细介绍，今天就只说如何搭建。

wget https://github.com/prometheus/prometheus/releases/download/v*/prometheus-*.*-amd64.tar.gz
tar xvf prometheus-*.*-amd64.tar.gz
cd prometheus-*.*

./prometheus --config.file=./prometheus.yml

wget https://github.com/prometheus/node_exporter/releases/download/v*/node_exporter-*.*-amd64.tar.gz
tar xvfz node_exporter-*.*-amd64.tar.gz
cd node_exporter-*.*-amd64
./node_exporter

./node_exporter --web.listen-address=:9200

yml
scrape_configs:
 -
job_name: 'node'
static_configs:
     -
targets: ['localhost:9200']  # 这里改为9200端口

搭建grfana

官网

https://grafana.com/grafana/download

Wget https://dl.grafana.com/oss/release/grafana-9.5.1-1.x86_64.rpm
sudo yum install -y https://dl.grafana.com/oss/release/grafana-9.5.1-1.x86_64.rpm

https://grafana.com/docs/grafana/latest/setup-grafana/installation/redhat-rhel-fedora/
systemctl start Grafana-server
https://grafana.com/docs/grafana/latest/setup-grafana/start-restart-grafana/
To start the service, run the following commands:
sudo systemctl daemon-reload
sudo systemctl start grafana-server
sudo systemctl status grafana-server
To verify that the service is running, run the following command:
sudo systemctl status grafana-server
Configure the Grafana server to start at boot using systemd
To configure the Grafana server to start at boot, run the following command:

sudo systemctl enable grafana-server.service

/etc/grfana/default.ini

引入数据源

填入prometheus数据源

locahost要改成实际的ip：9090

引入Grafana面板
