1.setup prom
https://github.com/prometheus/prometheus/releases/tag/v1.6.2
nohup ./prometheus --config.file=prometheus.yml &
WEB頁面訪問http://localhost:9090/ ，可以看到Prometheus的graph頁面。
2 熱加載配置
curl -X POST http://localhost:9090/-/reload
3 node exporter / mysql exporter client
https://prometheus.io/download/
mysql 還需要編輯：.my.cnf
[client] host=127.0.0.1 user=fast password=1qaz@WSX
nohup ./node_exporter &
nohup ./mysqld_exporter --config.my-cnf=".my.cnf" &
通過localhost:9104，9100 就可以看到exporter導出的數據了：
4 server vi prometheus.yml
37 - job_name: 'linux' 38 static_configs: 39 - targets: ['192.168.57.67:9100'] 40 labels: 41 instance: db1
31 - job_name: 'mysql' 32 static_configs: 33 - targets: ['192.168.57.67:9104'] 34 labels: 35 instance: db1
重啟prometheus，點擊導航欄中的status->targets可以看到，mysql的exporter已經集成進來了。
