安装lm-sensor检测cpu

1. sudo apt-get install lm-sensors
2. 运行mkdev.sh脚本
   1. 用vi或者gedit建立文件mkdev.sh，内容如下：

      #!/bin/bash
      # Here you can set several defaults.
      # The number of devices to create (max: 256)
      NUMBER=32
      # The owner and group of the devices
      OUSER=root
      OGROUP=root
      # The mode of the devices
      MODE=600
      
      # This script doesn't need to be run if devfs is used
      if [ -r /proc/mounts ] ; then
      if grep -q "/dev devfs" /proc/mounts ; then
      echo "You do not need to run this script as your system uses devfs."
      exit;
      fi
      fi
      
      i=0;
      
      while [ $i -lt $NUMBER ] ; do
      echo /dev/i2c-$i
      mknod -m $MODE /dev/i2c-$i c 89 $i || exit
      chown "$OUSER:$OGROUP" /dev/i2c-$i || exit
      i=$[$i + 1]
      done
      #end of file

2. 并使文件可执行，sudo chmod 755 mkdev.sh
3. 运行mkdev.sh，sudo ./mkdev.sh

     4.   sudo sensors-detect，回答一些问题，基本全是按默认来的。只有最后选择ISA bus还是SMBus Bus时可以凭个人喜好，不过我还是选的ISA。最后会有一个需加载的模块列表，类似于

#----cut here----
# Chip drivers
w83627hf
#----cut here----

      5. 记住这些，然后 sudo /etc/init.d/module-init-tools把以上列表中模块逆序添加进/etc/modules文件中

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

lp
mousedev
psmouse

# For Im-sensors, i2c modules
w83627hf

       6. 手动加载模块并更新依赖关系

sudo modprobe w83627hf
sudo depmod -a <并非必需>
sudo update-modules <并非必需>

        7. 最后，测试sensor输出

truth@dogfox:~$ sudo sensors

         8.  重启


         9.    如果是debian，可以sudo apt-get install sensors-apple，我现在使的Ubuntu Breezy的库里竟然没有这个包，只好从Debian站点上下载.deb文件用sudo dpkg -i xxxx.deb安装的。重启X后，Gnome的“添加到面板”里就应该有个叫“hardware sensors monitor”的Applet了。
