一、安装Prometheus
官网下载地址:Download | Prometheus
解压:tar -zxvf prometheus-2.19.2.linux-amd64.tar.gz
重命名: mv prometheus-2.19.2.linux-amd64 /home/prometheus
进入对应目录: cd /home/prometheus
查看配置文件:cat prometheus.yml
# 前台启动
./prometheus --config.file=prometheus.yml
# 后台启动
nohup ./prometheus --config.file=prometheus.yml > ./prometheus.log 2>&1 &
验证是否成功:http://***.***.***.***:9090/graph

如果查不到数据可以检查下我们的targets是否有报错

二、安装Grafana
官方下载地址:Download Grafana | Grafana Labs
下载:wget https://dl.grafana.com/oss/release/grafana-7.0.5-1.x86_64.rpm
安装:yum install grafana-7.0.5-1.x86_64.rpm
启动:systemctl daemon-reload
systemctl enable grafana-server.service
systemctl start grafana-server.service
验证是否成功:http://***.***.***.***:3000
默认用户名密码都是admin,初次登录会要求修改默认的登录密码
添加数据源
1.点击DATA SOURCES

2.选择Prometheus

3.Dashboards中import "Prometheus 2.0 Stats"

4.Settings界面填写服务器地址
5.切换界面

五、添加监控项
1.linux
下载node_exporter:
解压:tar -zxvf node_exporter-1.0.1.linux-amd64.tar.gz
启动: ./node_exporter &
注释:记得查看防火墙9100端口是否开启
这时候会看到如下警告
level=info ts=2020-07-09T02:24:55.402Z caller=tls_config.go:170 msg="TLS is disabled and it cannot be enabled on the fly." http2=false
这是因为Node Exporter 自v1.0.0 版本加了TLS验证(这个在后序篇幅讲,此次跳过)
到官网选择一个喜欢的仪表盘:Dashboards | Grafana Labs

查看id
导入仪表盘

在文本框里输入对应id即可导入
