Prometheus 安裝部署方法

node_exporter：用於*nix系統監控，使用go語言編寫的收集器。

docker run -d -p 9100:9100 -v "/proc:/host/proc" -v "/sys:/host/sys" -v "/:/rootfs" --net=

"host" --name=node-exporter quay.io/prometheus/node-exporter:v0.18.0

wget 

tar -xvzf node_exporter.tar.gz
cd node_exporter-0.18.1.linux-amd64 
nohup ./node_exporter --web.listen-address=
":11119"
&

docker run -p 9090:9090 --name prometheus -v /tmp/prometheus.yml:/etc/prometheus/prometheus.yml \

prom/prometheus

scrape_configs:

- job_name: 'prometheus'
static_configs:
# 監控本地及埠
- targets: ['localhost:9090']

wget 

tar xvf prometheus-2.10.0.linux-amd64.tar.gz 
mv prometheus-2.10.0.linux-amd64 /usr/local/prometheus

groupadd prometheus

useradd -g prometheus -m -d /var/lib/prometheus -s /sbin/nologin prometheus
chown prometheus.prometheus -r /usr/local/prometheus

cat
