一、node_exporter安装部署
[root@node00 ~]# cd /usr/src/
[root@node00 src]# wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz
[root@node00 src]# mkdir /usr/local/exporter -pv
mkdir: created directory ‘/usr/local/exporter’
[root@node00 src]# tar xf node_exporter-0.18.1.linux-amd64.tar.gz -C /usr/local/exporter/
[root@node00 src]# cd /usr/local/exporter/
[root@node00 exporter]# ls
node_exporter-0.18.1.linux-amd64
[root@node00 exporter]# ln -s node_exporter-0.18.1.linux-amd64/ node_exporter
二、node_exporter启动
[root@node00 node_exporter]# ./node_exporter
INFO[0000] Starting node_exporter (version=0.18.1, branch=HEAD, revision=3db77732e925c08f675d7404a8c46466b2ece83e) source="node_exporter.go:156"
INFO[0000] Build context (go=go1.12.5, user=root@b50852a1acba, date=20190604-16:41:18) source="node_exporter.go:157"
INFO[0000] Enabled collectors: source="node_exporter.go:97"
# 中间输出省略
INFO[0000] Listening on :9100 source="node_exporter.go:170"
三、测试node_exporter
[root@node00 ~]# curl 127.0.0.1:9100/metrics<br># 这里可以看到node_exporter暴露出来的数据。
四、配置node_exporter开机自启
[root@node00 system]# cd /usr/lib/systemd/system
# 准备systemd文件
[root@node00 systemd]# cat node_exporter.service

# 开机自启
[root@node00 exporter]# systemctl enable node_exporter
五、配置prometheus采集node信息
5.1 修改配置文件
[root@node00 prometheus]# cd /usr/local/prometheus/prometheus
[root@node00 prometheus]# vim prometheus.yml
# 在scrape_configs中加入job node ,最终scrape_configs如下配置
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: 'prometheus'
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
- targets: ['localhost:9090']
- job_name: "node"
static_configs:
- targets:
- "192.168.100.10:20001"
[root@node00 prometheus]# systemctl restart prometheus
[root@node00 prometheus]# systemctl status prometheus
