## 背景 ##

系统 Centos7.x，部署了node-exporter后当服务重启后，node-exporter 服务会停掉需要设置 node-exporter 开机自启，node\_exporter 版本为 **node\_exporter-0.18.1.linux-amd64**

## 解决方式 ##

思路，通过 systemctl 来管理

**条件**

*  脚本执行用户具有 sudo 权限

bash 脚本

#!/bin/bash
    
    set -e
    
    if [ -d $HOME/node_exporter-0.18.1.linux-amd64/ ];then
      sudo cp $HOME/node_exporter-0.18.1.linux-amd64/node_exporter /usr/local/bin/
    else
      echo "请检查 node_exporter 所在文件目录"
      exit 1
    fi
    
    sudo touch /usr/lib/systemd/system/node_exporter.service
    sudo chmod o+w /usr/lib/systemd/system/node_exporter.service
    sudo chmod o+x /usr/local/bin/node_exporter
    
    cat << EOF > /usr/lib/systemd/system/node_exporter.service [Service] User=$USER Group=$USER ExecStart=/usr/local/bin/node_exporter [Install] WantedBy=multi-user.target [Unit] Description=node_exporter After=network.target EOF
    
    sudo systemctl daemon-reload
    sudo systemctl start node_exporter
    sudo systemctl enable node_exporter
    sudo systemctl status node_exporter
    echo 'end success'

**ExecStart 可以自定义启动参数**
