linux查看cpu温度命令

　　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：

学习啦在线学习网 　　#yum install -y lm_sensors

学习啦在线学习网 　　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.

学习啦在线学习网 　　Some south bridges, CPUs or memory controllers contain embedded sensors.

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

学习啦在线学习网 　　Silicon Integrated Systems SIS5595... No

　　VIA VT82C686 Integrated Sensors... No

学习啦在线学习网 　　VIA VT8231 Integrated Sensors... No

　　AMD K8 thermal sensors... No

　　AMD Family 11h thermal sensors... No

　　Intel digital thermal sensor... Success!

学习啦在线学习网 　　(driver `coretemp')

　　Intel AMB FB-DIMM thermal sensor... No

　　VIA C7 thermal and voltage sensors... No

学习啦在线学习网 　　Some Super I/O chips contain embedded sensors. We have to write to

学习啦在线学习网 　　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

学习啦在线学习网 　　Found `SMSC EMC2700LPC Super IO'

　　(no information available)

学习啦在线学习网 　　Probing for Super-I/O at 0x4e/0x4f

学习啦在线学习网 　　Trying family `National Semiconductor'... No

　　Trying family `SMSC'... No

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

学习啦在线学习网 　　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

学习啦在线学习网 　　there, we have to read from arbitrary I/O ports to probe for such

学习啦在线学习网 　　interfaces. This is normally safe. Do you want to scan for IPMI

学习啦在线学习网 　　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

学习啦在线学习网 　　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.

学习啦在线学习网 　　Do you want to probe the I2C/SMBus adapters now? (YES/no):

　　Sorry, no supported PCI bus adapters found.

学习啦在线学习网 　　Module i2c-dev loaded successfully.

学习啦在线学习网 　　Now follows a summary of the probes I have just done.

　　Just press ENTER to continue:

学习啦在线学习网 　　Driver `coretemp':

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

　　Driver `ipmisensors':

学习啦在线学习网 　　* 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.

学习啦在线学习网 　　Otherwise, check http://www.lm-sensors.org/wiki/Devices for

学习啦在线学习网 　　driver availability.

学习啦在线学习网 　　Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no):

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

学习啦在线学习网 　　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)

学习啦在线学习网 　　Core 10: +48.0°C (high = +85.0°C, crit = +95.0°C)

　　coretemp-isa-0001

学习啦在线学习网 　　Adapter: ISA adapter

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

学习啦在线学习网 　　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)

学习啦在线学习网 　　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：

学习啦在线学习网 　　[root@vm-36 ~]# chkconfig lm_sensors on

学习啦在线学习网 　　[root@vm-36 ~]# service lm_sensors start

学习啦在线学习网 　　Starting lm_sensors: loading module ipmi-si coretemp [ OK ]
