Install the test system:hardware: Ordinary PC,software: Redhat Linux as 4 2.6.9, installation system comes with lm_sensors-2.8.7-2.i386You can also download it from [Url]http://www.edgedesign.us/about/lm_sensors[/url]This software can collect the system temperature under Linux. Then I show it with cacti. because it comes with the system. So I installed the system when the installation is ready. So if you can't find it. Can be found on the system disk, and then RPM installation. I'm not going to say that. let's look at the configuration:Run:/sbin/depmod–avi/etc/ld.so.confJoin this line:/usr/local/libRun: Ldconfigrun: Sensors-detect scan your host using those chipsets1:we can start with probing for (PCI) i²c or SMBus adapters.You don't need any special privileges for this.want to probe now?

If you had the choice, do you want to use the ISA bus or theI2c/smbus (isa/smbus)? ISADisplay:to make the sensors modules behave correctly, add these lines to/etc/modules.conf: #----Cut here----# i²c Module Optionsalias char-major-89 I2c-dev#----Cut here---- to load everything, which is needed, the add this to some/etc/rc* file: #----Cut here----# I²C Adapter Driversmodprobe I2c-isa# I²C Chip Driversmodprobe W83627HF# sleep 2 # optional/usr/bin/sensors-s # recommended#----Cut here---- warning! If you had some things built into your kernel, the list aboveWould contain too many modules. Skip the appropriate ones!
