- 输入以下命令
sudo apt-get update
sudo apt-get upgrade - 安装watchdog软件
sudo apt-get install watchdog - 修改文件
sudo nano /lib/systemd/system/watchdog.service
#追加以下内容
WantedBy=multi-user.target - 设置watchdog开机启动
sudo update-rc.d watchdog enable - 启动树莓派CPU看门狗模块
sudo modprobe bcm2835_wdt (以前版本为modprobe bcm2708_wdog） - 修改watchdog配置文件
sudo nano /etc/watchdog.conf
做如下修改
#ping = 172.31.14.1
#ping = 172.26.1.255
#interface = eth0
#file = /var/log/messages
#change = 1407
# Uncomment to enable test. Setting one of these values to'0'disables it.
# These values will hopefully never reboot your machine during normal use
# (if your machine is really hung, the loadavg will go much higher than 25)
max-load-1 = 24
#max-load-5 = 18
#max-load-15 = 12
# Note that this is the number of pages!
# To get the real size, check how large the pagesize is on your machine.
#min-memory = 1
#allocatable-memory = 1
#repair-binary = /usr/sbin/repair
#repair-timeout =
#test-binary =
#test-timeout =
watchdog-device = /dev/watchdog
watchdog-timeout = 10 这是添加的
# Defaults compiled into the binary
#temperature-device =
#max-temperature = 120
# Defaults compiled into the binary
#admin = root
#interval = 1
#logtick = 1
#log-dir = /var/log/watchdog
# This greatly decreases the chance that watchdog won't be scheduled before
# your machine is really loaded
realtime = yes
priority = 1
# Check if rsyslogd is still running by enabling the following line
#pidfile = /var/run/rsyslogd.pid - 该处不需要做修改，以前版本需要修改
sudo nano /etc/default/watchdog
该文件中的watchdog_module 字段的值不需要修改为bcm2835_wdt，不需要修改 - 重启主机
sudo reboot - 输入以下内容测试主机是否会重启
