centos7使用yum方式安裝node_exporter

官網下載地址：https://prometheus.io/download/

選擇對應的系統版本

官網提供的是壓縮包，點擊旁邊的github地址

github頁面顯示的有yum安裝和docker安裝，這里選擇“RHEL/CentOS/Fedora”

進入到yum方式安裝頁面

根據系統版本下載repo文件，我這里是centos7

# curl -Lo /etc/yum.repos.d/_copr_ibotty-prometheus-exporters.repo https://copr.fedorainfracloud.org/coprs/ibotty/prometheus-exporters/repo/epel-7/ibotty-prometheus-exporters-epel-7.repo
# yum makecache
# yum install node_exporter -y

常用命令

# systemctl start node_exporter.service
# systemctl status node_exporter.service
# systemctl enable node_exporter.service

# curl -Lo /etc/yum.repos.d/_copr_ibotty-prometheus-exporters.repo https://copr.fedorainfracloud.org/coprs/ibotty/prometheus-exporters/repo/epel-7/ibotty-prometheus-exporters-epel-7.repo
# yum makecache && yum install node_exporter -y

修改一下啟動文件
# vim /usr/lib/systemd/system/node_exporter.service
