下载安装prometheus$ wget https://github.com/prometheus/prometheus/releases/download/v1.7.1/prometheus-1.7.1.linux-amd64.tar.gz
$ mkdir/opt/prometheus
$ tar zxf prometheus-1.7.1.linux-amd64.tar.gz-C /opt/prometheus --strip-components=1
编辑配置prometheus.yml文件，内容如下：
global:
scrape_interval: 15s
evaluation_interval: 15s
external_labels:
monitor: 'codelab-monitor'
rule_files:
scrape_configs:
- job_name: 'prometheus'
static_configs:
- targets: ['192.168.1.199:9090']
- job_name: linux
static_configs:
- targets: ['192.168.1.199:9100']
labels:
instance: db1
- job_name: mysql
static_configs:
- targets: ['192.168.1.199:9104']
labels:
instance: db1
后台启动prometheus
nohup /opt/prometheus/prometheus -config.file=prometheus.yml &
tail -200f nohup.out
