Solaris-与硬件相关的查看硬件信息命令

1、查看硬件信息命令1, 主板信息.查看主板的序列号-#使用命令dmidecode | grep -i serial number#查看板卡信息cat /proc/pci-2, cpu信息-#通过/proc文件系统1) cat /proc/cpuinfo#通过查看开机信息2) dmesg | grep -i cpu#3)dmidecode -t processor-3, 硬盘信息-#查看分区情况fdisk -l#查看大小情况df -h#查看使用情况du -h#hdparm -I /dev/sda#dmesg | grep sda-4, 内存信息-1) cat /proc/meminfo2) dme

2、sg | grep mem3) free -m4) vmstat5) dmidecode | grep -i mem-5, 网卡信息-1) dmesg | grep -i eth2) cat /etc/sysconfig/hwconf | grep -i eth3) lspci | grep -i eth-6, 鼠标键盘和USB信息查看键盘和鼠标：cat /proc/bus/input/devices查看USB设备：cat /proc/bus/usb/devices查看各设备的中断请求(IRQ):cat /proc/interrupts7, 显卡信息-1)lspci |grep -i VGA2

3、)dmesg | grep -i VGA-8, 声卡信息-1)lspci |grep -i VGA2)dmesg | grep -i VGA-7, 其他命令.用硬件检测程序kuduz探测新硬件：service kudzu start ( or restart).dmesg (查看所有启动时检测到的硬件信息).lspci (显示外设信息, 如usb，网卡等信息).cat /etc/sysconfig/hwconf.mpstat8, 需要手动安装的工具lshw,hwinfo,hal-device-manager9, Solaris如何检测硬件参数俺从别处发现了些有意思的东西：Solaris的硬件相

57、能还是相当强大的，相信满足一般用户需求没有任何问题。二、 Libxml2安装：一般如果在安装系统的时候选中了所有开发库和开发工具的话(Fedora Core系列下)，应该不用安装，下面介绍一下手动安装： 1) 从xmlsoft站点或ftp()站点下载libxml压缩包(libxml2-xxxx.tar.gz)2) 对压缩包进行解压缩 tar xvzf libxml2-xxxx.tar.gz3) 进入解压缩后的文件夹中运行 ./configure -prefix /home/user/myxml/xmlinst(此处为待安装的路径)或者直接使用 ./configure make make ins

58、tall 4) 添加路径 export PATH=/home/user/myxml/xmlinst/bin:$PATH 说明：为了结构清晰，最好将libxml2不安装在解压目录中。安装完成后就可以使用简单的代码解析XML文件，包括本地和远程的文件，但是在编码上有一些问题。Libxml默认只支持UTF8的编码，无论输入输出都是UTF-8，所以如果你解析完一个XML得到的结果都是UTF8的，如果需要输出GB2312或者其它编码，需要ICONV来做转码(生成UTF8编码的文件也可以用它做),如果系统中没有安装iconv的话，需要安装libiconv。 1) 下载libiconv压缩包(例如libic

59、onv-1.11.tar.gz) 2) 对压缩包进行解压缩tar xvzf libiconv-1.11.tar.gz 3) 进入解压缩后的文件夹中运行 ./configure make make install三、关于XML：在开始研究 Libxml2 库之前，先了解一下XML的相关基础。XML 是一种基于文本的格式，它可用来创建能够通过各种语言和平台访问的结构化数据。它包括一系列类似 HTML 的标记，并以树型结构来对这些标记进行排列。例如，可参见清单 1 中介绍的简单文档。为了更清楚地显示 XML 的一般概念，下面是一个简化的XML文件。清单 1. 一个简单的 XML 文件 root de

60、lete 10清单 1 中的第一行是 XML 声明，它告诉负责处理 XML 的应用程序，即解析器，将要处理的 XML 的版本。大部分的文件使用版本 1.0 编写，但也有少量的版本 1.1 的文件。它还定义了所使用的编码。大部分文件使用 UTF-8，但是，XML 设计用来集成各种语言中的数据，包括那些不使用英语字母的语言。接下来出现的是元素。一个元素以开始标记 开始(如 )，并以结束标记 结束(如 )，其中使用斜线 (/) 来区别于开始标记。元素是 Node 的一种类型。XML 文档对象模型 (DOM) 定义了几种不同的 Nodes 类型，包括:Elements(如 files 或者 age)A
