我们可能会关心自己的电脑或者服务器CPU的温度，如何在linux中快速查看CPU温度呢?下面由学习啦小编为大家整理了linux查看cpu温度命令的相关知识，希望大家喜欢!

Linux查看cpu温度命令

lm_sensors提供了一套方案，可以自动侦测主板传感器的型号和读取方式，可以在命令行模式下快速安装运行。

在CentOS系统中安装使用实例如下：

#yum install -y lm_sensors

然后运行sensors-detect来探测传感器类型，此命令会给出一些问题，一律回答Yes即可：

[root@vm-36 ~]# sensors-detect

Stopping lm_sensors: [FAILED]

# sensors-detect revision 1.1

# System: Dell Inc. PowerEdge R710

# Board: Dell Inc. 0XDX06

This program will help you determine which kernel modules you need

to load to use lm_sensors most effectively. It is generally safe

and recommended to accept the default answers to all questions,

unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.

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

Silicon Integrated Systems SIS5595... No

VIA VT82C686 Integrated Sensors... No

VIA VT8231 Integrated Sensors... No

AMD K8 thermal sensors... No

AMD Family 11h thermal sensors... No

Intel digital thermal sensor... Success!

(driver `coretemp')

Intel AMB FB-DIMM thermal sensor... No

VIA C7 thermal and voltage sensors... No

Some Super I/O chips contain embedded sensors. We have to write to

standard I/O ports to probe them. This is usually safe.

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

Probing for Super-I/O at 0x2e/0x2f

Trying family `National Semiconductor'... No

Trying family `SMSC'... Yes

Found `SMSC EMC2700LPC Super IO'

(no information available)

Probing for Super-I/O at 0x4e/0x4f

Trying family `National Semiconductor'... No

Trying family `SMSC'... No

Trying family `VIA/Winbond/Nuvoton/Fintek'... No

Trying family `ITE'... No

Some systems (mainly servers) implement IPMI, a set of common interfaces

through which system health data may be retrieved, amongst other things.

We first try to get the information from SMBIOS. If we don't find it

there, we have to read from arbitrary I/O ports to probe for such

interfaces. This is normally safe. Do you want to scan for IPMI

interfaces? (YES/no):

Found `IPMI BMC KCS' at 0xca8... Success!

(confidence 8, driver `ipmisensors')

Some hardware monitoring chips are accessible through the ISA I/O ports.

We have to write to arbitrary I/O ports to probe them. This is usually

safe though. Yes, you do have ISA I/O ports even if you do not have any

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

Lastly, we can probe the I2C/SMBus adapters for connected hardware

monitoring devices. This is the most risky part, and while it works

reasonably well on most systems, it has been reported to cause trouble

on some systems.

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

Sorry, no supported PCI bus adapters found.

Module i2c-dev loaded successfully.

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

Just press ENTER to continue:

Driver `coretemp':

* Chip `Intel digital thermal sensor' (confidence: 9)

Driver `ipmisensors':

* ISA bus, address 0xca8

Chip `IPMI BMC KCS' (confidence: 8)

Warning: the required module ipmisensors is not currently installed

on your system. If it is built into the kernel then it's OK.

Otherwise, check http://www.lm-sensors.org/wiki/Devices for

driver availability.

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

Starting lm_sensors: loading module ipmi-si coretemp [ OK ]

Unloading i2c-dev... OK

最后运行sensors命令来查看CPU温度

[root@vm-36 ~]# sensors

coretemp-isa-0000

Adapter: ISA adapter

Core 0: +44.0°C (high = +85.0°C, crit = +95.0°C)

Core 1: +44.0°C (high = +85.0°C, crit = +95.0°C)

Core 9: +46.0°C (high = +85.0°C, crit = +95.0°C)

Core 10: +48.0°C (high = +85.0°C, crit = +95.0°C)

coretemp-isa-0001

Adapter: ISA adapter

Core 0: +45.0°C (high = +85.0°C, crit = +95.0°C)

Core 1: +45.0°C (high = +85.0°C, crit = +95.0°C)

Core 9: +49.0°C (high = +85.0°C, crit = +95.0°C)

Core 10: +46.0°C (high = +85.0°C, crit = +95.0°C)

我们还可以将lm_sensors服务设置为自动启动，以便自动加载相关模块：

[root@vm-36 ~]# chkconfig lm_sensors on

[root@vm-36 ~]# service lm_sensors start

Starting lm_sensors: loading module ipmi-si coretemp [ OK ]
