CentOS终端下查看CPU温度


炎炎夏日到来,我们可能会关心自己的电脑或者服务器CPU的温度,如果在Linux系统中快速查看CPU温度呢?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:[[email protected] ~]# sensors-detectStopping lm_sensors: [FAILED]# sensors-detect revision 1.1# System: Dell Inc. PowerEdge R710# Board: Dell Inc. 0XDX06This program will help you determine which kernel modules you needto load to use lm_sensors most effectively. It is generally safeand 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... NoVIA VT82C686 Integrated Sensors... NoVIA VT8231 Integrated Sensors... NoAMD K8 thermal sensors... NoAMD Family 11h thermal sensors... NoIntel digital thermal sensor... Success! (driver `coretemp')Intel AMB FB-DIMM thermal sensor... NoVIA C7 thermal and voltage sensors... NoSome Super I/O chips contain embedded sensors. We have to write tostandard 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/0x2fTrying family `National Semiconductor'... NoTrying family `SMSC'... YesFound `SMSC EMC2700LPC Super IO' (no information available)Probing for Super-I/O at 0x4e/0x4fTrying family `National Semiconductor'... NoTrying family `SMSC'... NoTrying family `VIA/Winbond/Nuvoton/Fintek'... NoTrying family `ITE'... NoSome systems (mainly servers) implement IPMI, a set of common interfacesthrough which system health data may be retrieved, amongst other things.We first try to get the information from SMBIOS. If we don't find itthere, we have to read from arbitrary I/O ports to probe for suchinterfaces. This is normally safe. Do you want to scan for IPMIinterfaces? (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 usuallysafe though. Yes, you do have ISA I/O ports even if you do not have anyISA slots! Do you want to scan the ISA I/O ports? (YES/no):Lastly, we can probe the I2C/SMBus adapters for connected hardwaremonitoring devices. This is the most risky part, and while it worksreasonably well on most systems, it has been reported to cause troubleon 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 installedon your system. If it is built into the kernel then it's OK.Otherwise, check http://www.lm-sensors.org/wiki/Devices fordriver 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:[[email protected] ~]# sensorscoretemp-isa-0000Adapter: ISA adapterCore 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-0001Adapter: ISA adapterCore 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:[[email protected] ~]# chkconfig lm_sensors on[[email protected] ~]# service lm_sensors startStarting lm_sensors: loading module ipmi-si coretemp [ OK ]lm_sensors项目官方网站:http://lm-sensors.org/
