安裝 nut ups tool

x213212@x213212-desktop:~$ sudo apt-get install nut-server nut-client nut-monitor s-nail

基礎設定

x213212@x213212-desktop:/etc/nut$ lsusb

一定要設置 你的 usb "bus" 和 "device" 如上
確定抓到 American Power Conversion Uninterruptible Power

Bus 001 Device 007: ID 051d:0002 American Power Conversion Uninterruptible Power

Bus 001 Device 002: ID 0bda:5411 Realtek Semiconductor Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

once try these things,

You can use lsusb to find out the bus and device number

Then change permission to the device

chmod 0666 /dev/bus/usb/[bus number]/[device number]

as for details go with rouble starting Network UPS Tools with a Eaton 3S UPS

設定完

系統配置

x213212@x213212-desktop:/etc/nut$ sudo upsc mge

就可以順利看到我們的ups 內容囉~


shutdown -h now

https://www.vediotalk.com/?p=2211
跟著設權限

有囉~

安裝 sshpass

開始寫小東西

apt-get install sshpass
sshpass -p rootx root@192.168.0.105

那個我們只要跟著下

sshpass -p rootx ssh root@192.168.0.105 'shutdown -h now'
我們的nas就關機囉

那我們在 我們上次的ubuntu 來寫script吧~

簡單script 設置什麼好亂 乾脆自己來xd

while :
do
        clear
        sleep 1
        TAROUTPUT=$( upsc mge | grep -E "ups.status")
        TAROUTPUT2=$( upsc mge | grep -E "battery")


        substr=$( echo ${TAROUTPUT/ups.status: /""})
#       echo $substr
#       if [ $substr == "OL" or $substr == "OL CHRG"]; then
           #     echo "good"
          #  else
         #       echo "bad"
        #fi
          case "$substr" in
          "OL CHRG") echo "充電中"
             ;;
          "OL") echo "已經完全充滿"
             ;;
          *) echo "已經拔除電源，通知系統關機。"
                  sshpass -p rootx ssh root@192.168.0.105 'shutdown -h now'                                                                                                                      break;
          esac
#       echo  $substr
#       echo $TAROUTPUT
#       echo "\n"
 #       echo $TAROUTPUT2
done




背景執行

nohup bash ups.sh ＆> /dev/null ＆

jobs 可以看到運行中的 任務
這樣 斷電的時候我的 nas 就可以自動關機囉~

自幹系列 2

沒有像

這樣的畫面呢
來寫一個陽春的監測畫面好了node.js~




































let express = require('express');
let app = express();
let router = express.Router();
let exec = require('child_process').exec;
let port = 9000;
//app.use(express.static(__dirname + '/public'));
//app.use('/img', express.static(__dirname + '/public/img'));

let header = '<!DOCTYPE html><html><head><title>ctrl PHP</title>'

let footer = "</pre></body></html>";

router.get('/', function (req, res, next) {
    //預設頁面
    console.log('index');
    res.sendfile('index.html', {root: __dirname + "/public"});
});
router.get('/ls', function (req, res, next) {
    //執行 ls -al 指令
    exec('sudo upsc mge | grep -E "ups.status|battery"', function (err, stdout, stderr) {
        console.log('ls');
        res.send(header + stdout + footer + stderr + err );
    });
});

app.use('/', router);
app.listen(port);
app.listen(3000, function () {
          console.log('Example app listening on port 3000!');
});
