环境:centos7
思路:node_exporter插件收集服务器数据——prometheus存储插件收集的数据——grafana展示prometheus收集的数据
下载对应系统最新软件包prometheus和监控插件node_exporter
1、配置node_exporter成服务并修改端口
tar -zxvf node_exporter-1.0.1.linux-amd64.tar.gz cd node_exporter-1.0.1.linux-amd64 && cp node_exporter /usr/local/bin/ centos创建一个.service文件 cat << EOF > /usr/lib/systemd/system/node_exporter.service [Unit] Description=node_exporter After=network.target [Service] Type=simple User=root ExecStart=/usr/local/bin/node_exporter --web.listen-address=:19001 Restart=on-failure [Install] WantedBy=multi-user.target EOF 启动服务 systemctl daemon-reload systemctl start node_exporter && systemctl status node_exporter && systemctl enable node_exporter 验证:http://ip:19001/metrics
2、prometheus安装配置成服务
cat << EOF > /usr/lib/systemd/system/prometheus.service [Unit] Description=Prometheus Documentation=https://prometheus.io/ After=network.target [Service] Type=simple User=root ExecStart=/prometheus-2.24.1.linux-amd64/prometheus --config.file=/prometheus-2.24.1.linux-amd64/prometheus.yml --web.enable-lifecycle --storage.tsdb.retention=90d --web.listen-address=:19190 Restart=on-failure [Install] WantedBy=multi-user.target EOF 启动服务 systemctl daemon-reload systemctl start prometheus.service && systemctl status prometheus.service && systemctl enable prometheus.service 验证:http://ip:19190
配置文件修改
[root@node1 prometheus-2.24.1.linux-amd64]# cat prometheus.yml |grep -v '#' global: alerting: alertmanagers: - static_configs: - targets: rule_files: scrape_configs: - job_name: 'prometheus' static_configs: - targets: ['localhost:19001']
3、grafana安装
https://www.cnblogs.com/imyalost/p/9873641.html 参考 下载网址:https://grafana.com/grafana/download/7.3.7 wget https://dl.grafana.com/oss/release/grafana-7.3.7-1.x86_64.rpm sudo yum install grafana-7.3.7-1.x86_64.rpm 下载安装完成后,输入命令 systemctl start grafana-server 启动服务,打开浏览器,输入IP+端口,3000为Grafana的默认侦听端口。 系统默认用户名和密码为admin/admin,第一次登陆系统会要求修改密码,修改密码后登陆,界面显示如下:
4、grafana配置数据源prometheus,官网下载数据显示模板并导入,显示结果如下图所示:
