最近看了《温度决定生老病死》，而电脑也是《温度决定状态和寿命》，监测服务器各部件工作温度是非常重要的。我曾经有一台服务器屡屡坏硬盘，经监测后发现温度达60度，后来增加一个小风扇使其降到40度，故障就再也没有发生了。下面详述安装过程：
第一步：安装lm-sensors和sensors-applet(也可以选用后面新找到的一个软件CompTemp Monitor)，打开终端输入：
sudo apt-get install lm-sensors sensors-applet
根据提示键入Root密码，然后等待下载并安装完后关闭终端。在你想要显示传感器温度的面板位置右键，选择“添加到面板”菜单命令，在列表中选择 “Hardware Sensors Monitor”后单击“添加”按钮即可添加该Applet程序。能直接检测到传感器那最好了。如果没有检测到传感器(我的就没有显示)，显示”No sensors found”则转到下一步。
第二步：手动配置传感器：
Ubuntu安装的时候可能没有对传感器进行配置,需要手动配置传感器。lm-sensors软件提供了一个非常好的命令：sensors- detect，会自动侦测所需模块,类似Windows软件常见的“下一步”模式，引导你配置好传感器,向导中的问题按提示回答“Yes”或者 “ENTER”.一般一路下去输入”Yes”/”ENTER”就可以了,我检测配置的时候就一路Yes和ENTER.
在终端输入：
sudo sensors-detect
过程：

# sensors-detect revision 4171 (2006-09-24 03:37:01 -0700)
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.
We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no): yes
Probing for PCI bus adapters…
Use driver `i2c-viapro’ for device 0000:00:11.0: VIA Technologies VT8233A/8235 South Bridge
We will now try to load each adapter module in turn.
Module `i2c-viapro’ already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.
To continue, we need module `i2c-dev’ to be loaded.
Do you want to load `i2c-dev’ now? (YES/no): yes
Module loaded successfully.
We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence
value in that case.
If you found that the adapter hung after probing a certain address,
you can specify that address to remain unprobed.
Next adapter: SMBus Via Pro adapter at 0400
Do you want to scan it? (YES/no/selectively): yes

Some chips are also 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): yes
Probing for `National Semiconductor LM78′ at 0×290… No
Probing for `National Semiconductor LM78-J’ at 0×290… No

Probing for `IPMI BMC SMIC’ at 0xca8… No
Some Super I/O chips may also contain 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): yes
Probing for Super-I/O at 0×2e/0×2f

Just press ENTER to continue: ENTER
To make the sensors modules behave correctly, add these lines to
/etc/modules:
#—-cut here—-
# I2C adapter drivers
i2c-viapro
# Chip drivers
lm90
eeprom
it87
#—-cut here—-
#上面的内容是关键,列举了启动时要载入的模块,检测结果和我在Windows下用EVEREST Ultimate软件查得到主板的情况一致:VIA KT400的芯片组和传感器ITE IT8705F, National LM90 (ISA 290h, SMBus 4Ch),如果上述检测未能找到出你主板上的传感器,查看/usr/share/doc/lm-sensors/doc/lm_sensors- FAQ.html 或者去lm-sensors wiki: 查找解决方法.
Do you want to add these lines to /etc/modules automatically? (yes/NO)yes确认添加的模块:
sudo gedit /etc/modules
打开/etc/modules查看：
louis@Ubuntu-desktop:~$ sudo gedit /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with “#” are ignored.

第三步:安装其它监控软件xsensors，ksensors，gdesklets(gdesklets里有很多桌面小程序)，Gkrellm，hddtemp等,自己选择安装.
sudo apt-get install xsensors或者ksensors(KDE中推荐使用ksensors)
sudo apt-get install gdesklets gkrellm
安装硬盘温度监控:
sudo apt-get install hddtemp
安装完后重启系统就能正确监控了.
终端中输入sensors命令或者用xsensors或者ksensors就可随时监控CPU温度,风扇转速等硬件状态.
