万博网页版登陆页派的CPU是保护有硬件看门狗的,可以通过安装模块和值守程序来实现看门狗防止万博网页版登陆页派死机
安装看门狗:
方法一:
watchdog.sh的源码:
#!/usr/bin/env bash
echo "[+] Activating Temperature Sensor"
modprobe bcm2708_wdog
echo "bcm2708_wdog" >> /etc/modules
echo "[+]Installing Watchdog"
apt-get -y install watchdog chkconfig
echo "[+]Setting Up Watchdog"
chkconfig watchdog on
sed -i 's/#max-load-1[^5]/max-load-1\ /g' /etc/watchdog.conf
sed -i 's/#\(watchdog-device\t[\ ]*\)\=/\1\t\=/g' /etc/watchdog.conf
sed -i 's/#\(temperature-device[\ ]*\)\=/\1\ \= \/sys\/class\/thermal\/thermal\_zone0\/temp/g' /etc/watchdog.conf
sed -i 's/#\(max-temperature[\ ]*\)\=\ 120/\1\ \=\ 75000/g' /etc/watchdog.conf
sed -i 's/#\(interval[\ ]*\)\=\ 1/\1\ \=\ 10 /g' /etc/watchdog.conf
/etc/init.d/watchdog start
sudo sh watchdog.sh
====================================================================================
方法二:
1.加载看门狗模块,编辑/etc/modules文件,添加一行”bcm2708_wdog”
sudo modprobe bcm2708_wdog
sudo nano /etc/modules
添加一行”bcm2708_wdog”
2.安装系统配置软件和看门狗程序
sudo apt-get install chkconfig watchdog
3.配置看门狗程序,编辑“/etc/watchdog.conf”文件
sudo nano /etc/watchdog.conf
去掉 watchdog-device = /dev/watchdog 前的#号,让看门狗设备对应万博网页版登陆页派的硬件看门狗
去掉 max-load-1 = 24 前的#号,当1分钟load进程超过24个的时候就会重启
还可以设置高温复位:
去掉
temperature-device =
max-temperature = 120
前的#号,改为
temperature-device = /sys/class/thermal/thermal_zone0/temp
max-temperature = 80000
温度超过80度就会引起重启,保护CPU
配置完后,保存(Ctrl+O),退出(ctrl+x)
4.配置看门狗程序,开机自动运行
chkconfig watchdog on
5.启动看门狗
sudo /etc/init.d/watchdog start
输入下述命令(forkbomb),测试一下看门狗
