安装测试系统：

　　硬件：普通PC机，

　　软件：redhat linux as 4 2.6 .9 , 安装系统自带的lm_sensors-2.8.7-2.i386

　　你也可以从[url]http://www.edgedesign.us/about/lm_sensors[/url]下载

　　这个软件可以在linux下收集到系统温度。然后我用cacti显示。

　　由于是系统自带的。所以我在安装系统的时候就已经安装好的。所以如果你找不到的话。可以在系统盘上找，然后rpm安装。这个我就不说了。

　　下来看配置：

　　运行： /sbin/depmod –a

　　vi /etc/ld.so.conf

　　加入这一行： /usr/local/lib

　　运行： ldconfig

　　运行：sensors-detect 扫瞄你的主机使用那些芯片组

　　1： We can start with probing for (PCI) I2C or SMBus adapters.

　　You do not need any special privileges for this.

　　Do you want to probe now? (YES/no): YES

　　2：Next adapter: SMBus I801 adapter at 0500 (Algorithm unavailable)

　　Do you want to scan it? (YES/no/selectively): YES

　　3：Do you want to scan the ISA bus? (YES/no): YES

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

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

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

　　Just press ENTER to continue: 回车

　　7：I will now generate the commands needed to load the I2C modules.

　　Sometimes, a chip is available both through the ISA bus and an I2C bus.

　　ISA bus access is faster, but you need to load an additional driver module

　　for it. If you have the choice, do you want to use the ISA bus or the

　　I2C/SMBus (ISA/smbus)? ISA

　　显示：

　　To make the sensors modules behave correctly, add these lines to

　　/etc/modules.conf:

　　#----cut here----

　　# I2C module options

　　alias char-major-89 i2c-dev

　　#----cut here----

　　To load everything that is needed, add this to some /etc/rc* file:

　　#----cut here----

　　# I2C adapter drivers

　　modprobe i2c-isa

　　# I2C chip drivers

　　modprobe w83627hf

　　# sleep 2 # optional

　　/usr/bin/sensors -s # recommended

　　#----cut here----

　　WARNING! If you have some things built into your kernel, the list above

　　will contain too many modules. Skip the appropriate ones! You really should

　　try these commands right now to make sure everything is working properly.

　　Monitoring programs won't work until it's done.

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

　　Copy prog/init/lm_sensors.init to /etc/rc.d/init.d/lm_sensors

　　for initialization at boot time.

　　完成。

　　cat /etc/sysconfig/lm_sensors

　　显示：

　　MODULE_0=i2c-isa

　　MODULE_1=w83627hf

　　启动

　　[root@linux etc]# /etc/rc.d/init.d/lm_sensors start

　　Starting lm_sensors: [ OK ]

#p#副标题#e#

　　测试：运行 sensors

　　运行： ntsysv

　　设置lm_sensors 开机运行。

　　接下来 设置与 cacti整合：

　　编辑数据采集脚本

　　Vi mrtg.sh

　　#!/bin/sh

　　cputemp=`sensors | grep “CPU Temp“ | awk '{print $3}' | cut -c 2-3`

　　systemp=`sensors | grep temp3 | awk '{print $2}' | cut -c 2-3`

　　uptime=`uptime | awk '{print $3 “ “ $4 “ “ $5}'`

　　echo $cputemp

　　echo $systemp

　　echo $uptime

　　echo linux226

　　添加权限：chmod +x mrtg.sh

　　采集结果如下：

　　42

　　26

　　4:50, 2 users,

　　linux226

　　接下来改写档案

　　WorkDir: /var/www/html/mrtg/temp/

　　Language: big5

　　Target[index]: `/var/www/html/mrtg/temp/mrtg.temp`

　　MaxBytes[index]:60

　　Options[index]: gauge, nopercent, growright

　　YLegend[index]: Temp (度)

　　ShortLegend[index]: 度

　　LegendO[index]: 系统温度;

　　LegendI[index]: CPU温度;

　　Title[index]: Blue-Moon City 系统温度表

　　PageTop[index]:

Blue-Moon City 主机温度表

　　Mrtg添加：root#/usr/bin/mrtg /var/www/html/mrtg/temp/mrtg.cfg.temp

　　然后将上面这条命令加入crontab 里定时运行。

　　我在pc机测试没有问题。。IBM服务器测试没有成功，总是 sensors-detect 时候出错。

　　经查询：IBM服务器不建议用lm_sensors 软件。
