部署Func/Certmaster平台
Func简介
Func是由红帽子公司以Fedora平台统一网络控制器 Func（Fedora Unified Network Controller https://fedorahosted.org/func），目的是为了解决这一系列统一管理监控问题而设计开发的系统管理基础框架。 它是一个能有效的简化我们多服务器系统管理工作的工具，它很容易学习、很容易使用、也很容易被扩展，它功能强大而我们只需要非常非常少的配置和维护。
Func分为master及slave两部分，master为主控端，slave为被控端。以下为两部分的安装配置说明
一、Func 2.5版本安装文档[Master]

DD命令详解
1.命令简介
dd 的主要选项：
指定数字的地方若以下列字符结尾乘以相应的数字:
b=512, c=1, k=1024, w=2, xm=number m
if=file #输入文件名，缺省为标准输入。
of=file #输出文件名，缺省为标准输出。
ibs=bytes #一次读入 bytes 个字节(即一个块大小为 bytes 个字节)。
obs=bytes #一次写 bytes 个字节(即一个块大小为 bytes 个字节)。
bs=bytes #同时设置读写块的大小为 bytes ，可代替 ibs 和 obs 。
cbs=bytes #一次转换 bytes 个字节，即转换缓冲区大小。
skip=blocks #从输入文件开头跳过 blocks 个块后再开始复制。

定制自己的LiveCD，依托(centos)
1、建立自己的yum-repository或者使用官方的（考虑到你需要的软件小，所以这一步不是很必要）。
2、安装一个centos系统，修改etc/yum.repos.d/centos-livecd.repo文件内容
# Name: CentOS LiveCD repository [livecd] name = CentOS $releasever - LiveCD baseurl = http://www.nanotechnologies.qc.ca/propos/linux/centos-live/$basearch/live enabled=1 protect=0 gpgkey = http://www.nanotechnologies.qc.ca/propos/linux/RPM-GPG-KEY-PGuay 保存之后，执行以下命令：
Nginx整合Resin
操作系统：centos 5.4 64位
1，安装jdk,已经配置有yumrepository，直接使用。
yum install jdk
2，安装pcre,nginx运行所需perl库。
yum install pcre pcre-devel3，安装mysql ，mysql相关配置省略。
linux下的无盘工作站配置（centos）
需求：需要多个系统同运行同样的服务，如j2ee模块、memcached等，这些服务不与硬盘相关，只运行在内存中，并且多个系统同时运行，为了规避单点故障以及实现高效。
下面步骤是centos5.4系统的无盘服务端配置步骤，客户端只要选择从网络启动，即可在无干预情况下启动系统。
一，新建主要目录

二，拷贝预置模板到/diskless/x86_64/centos5.4/root目录

Oracle 11g Software Installation on Linux—CentOS-5
Introduction
This paper takes a look at installing oracle 11g (11.1) on Linux (CentOS-5).You can read about CentOS at www.centos.org and be assured of its’ Enterprise-class quality. This paper will use oracle’s Quick Installation Guide for Linux x86 as its’ guide—noting where additional information may be obtained but getting oracle installed on Linux as fast as possible. We at thecheapdba.com have years of experience installing oracle—starting back with oracle 7. We will point out best practices so that you end up with a reliable database that provides exceptional performance. We will occasionally re-visit, edit, and post additions to this paper as we find further configuration best practices.
This paper will not cover the installation of CentOS-5 as that can be acquired through the CentOS website and additional Linux guides. We will however point out those alterations to the Linux environment that pertains to getting oracle installed.
Our goal is to provide you with the steps to properly install the oracle 11g software without having to read oracle’s installation guide from front to back cover. We will provide you the commands to execute (just cut-n-paste) and the desired outcome of those commands. If you get something other than what is expected it would be time for you to re-visit earlier steps in this process. So hold on, here we go.
It is assumed that the installer of oracle software has access and is running on an X Window System workstation. Please consult X Server documentation if you need help. We at thecheapdba.com typically will use cygwin ( www.cygwin.com ) for all interfacing with our Linux distribution. It has an X Window System that works quite well—and as we always like is free.
