Linux查看机器CPU温度

Linux查看机器CPU温度

一、安装lm_sensors

[root@MPI_EXERCISE ~]# yum -y install lm_sensors

二、配置

[root@MPI_EXERCISE ~]# sensors-detect

Do you want to scan for them? This is totally safe. (YES/no): yes

Do you want to scan for Super I/O sensors? (YES/no): yes

This is normally safe. Do you want to scan for IPMI interfaces? (YES/no): yes

Do you want to scan the ISA I/O ports? (YES/no): yes

Do you want to probe the I2C/SMBus adapters now? (YES/no): yes

Next adapter: i915 gmbus ssc (i2c-0)

Do you want to scan it? (YES/no/selectively): yes

Next adapter: i915 gmbus vga (i2c-1)

Do you want to scan it? (YES/no/selectively): yes

Next adapter: i915 gmbus panel (i2c-2)

Do you want to scan it? (YES/no/selectively): yes

Next adapter: i915 gmbus dpc (i2c-3)

Do you want to scan it? (YES/no/selectively): yes

Next adapter: i915 gmbus dpb (i2c-4)

Do you want to scan it? (YES/no/selectively): yes

Next adapter: i915 gmbus dpd (i2c-5)

Do you want to scan it? (YES/no/selectively): yes

Now follows a summary of the probes I have just done.

Just press ENTER to continue: 

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): yes

Starting lm_sensors: loading module coretemp               [  OK  ]

Unloading i2c-dev... OK

三、查看温度

[root@MPI_EXERCISE ~]# sensors

acpitz-virtual-0

Adapter: Virtual device

temp1:       +27.8°C  (crit = +103.0°C)                  

temp2:       +29.8°C  (crit = +103.0°C)                  

coretemp-isa-0000

Adapter: ISA adapter

Physical id 0: +30.0°C  (high = +82.0°C, crit = +102.0°C)  

Core 0:        +25.0°C  (high = +82.0°C, crit = +102.0°C)  

Core 1:        +30.0°C  (high = +82.0°C, crit = +102.0°C) 

用watch sensors可以观察cpu温度的变化，每隔两秒更新一次。

[root@localhost ~]# watch sensors
