直接读取系统信息

可以通过读取如下路径中的数据来获取cpu的温度信息，不过读取的数据没有经过处理。

cpu0：
cat /sys/class/thermal/thermal_zone0/temp
cpu1：
cat /sys/class/thermal/thermal_zone1/temp

通过命令行的方式获取

安装 lm_sensors 软件包：

# rpm
yum install lm_sensors

# deb
apt-get install lm-sensors

执行命令sensors-detect，进行简单配置，此命令执行后会出现一系列选项，一直yes即可；

执行命令sensors，查看cpu的温度。
