　　过去两三年里，Oracle一直销售由它提供支持的基于Red Hat Enterprise Linux的发行版Oracle Enterprise Linux，但是Oracle的Linux主管称，两者之间存在重大差异，所以Oracle不是Red Hat的分支。Oracle Enterprise Linux与Red Hat Enterprise Linux二进制兼容，也就是能运行在Red Hat上的软件也能运行在Oracle上。

　　但是Oracle的Linux工程主管Wim Coekaerts表示，Oracle Enterprise Linux不是人们所认为的拷贝Red Hat，Linux发行版最要紧的是向用户提供高品质的操作系统，提供充分的支持，他说，“我们不想创造一个不同于Red Hat的新发行版，问题是关于支持而不是软件本身。”Oracle称它的想法是加强Linux，而不是从零开始创造一个，Oracle发行版与Red Hat的最大区别就是OCFS(Oracle Cluster File System)文件系统和基于Xen的OracleVM虚拟化技术。

摘要

Nginx下配置fastcgi

下文所述适用于
Nginx通过fastcgi调用python, Perl和C++等写的CGI程序。PHP不在本文讨论范围内，因为PHP有PHP-FPM (FastCGI Process Manager)，关于PHP-FPM的更多信息，请Google php-fpm+nginx。

 一、原理
Nginx并不提供支持对外部程序的直接调用或者解析（所以缺少像apache里的mod_php这样的模块），所有的外部程序（包括PHP）必须 通过fastcgi接口来调用，在Linux下接口是socket （文件socket或者Internet socket）。所以为了调用CGI程序，我们需要一个fastcgi的wrapper，这个wrapper绑定在某个固定socket上（比如端口或者 文件socket），当nginx将CGI请求发送给这个socket的时候，wrapper接纳请求并fork一个新的线程，这个线程调用外部的程序或 者解释器处理脚本并读取返回值，而wrapper再将返回的数据（网页或者图片等）通过fastcgi将数据通过那个固定的socket传递给 nginx。示意图如下：

Php5.2.14 安装后的加速和安全

 下文所述适用于RHEL、CENTOS、FREEBSD环境，其他未做测试。

一、加速
eAccelerator已经是很常用的PHP平台预编译加速的手段了，加速方面我们就采用这个软件
获得源代码：
https://bart.eaccelerator.net/source/

编译：需要有autoconf支持，解包后在源程序目录下：

 /usr/local/php/bin/phpize

 ./configure –enable-eaccelerator=shared –with-php-config=/usr/local/php/bin/php-config

 make;make install

顾名思义，就是文档，无他，在这些日子发现BLOG有个缺点就是大文档阅读的不连贯性，所以打算把文档整理为PDF格式，发布在文档区，BLOG中会做相应介绍！还有就是其他兄弟姐妹们有好的文档希望让大家看到的也可以在主页上的意见和建议中告诉我，我会给你开通相应通道的，为开源多做贡献。

Security Enhancements and Fixes in PHP 5.2.14:

• Rewrote var_export() to use smart_str rather than output buffering, prevents data disclosure if a fatal error occurs.
• Fixed a possible interruption array leak in strrchr().(CVE-2010-2484)
• Fixed a possible interruption array leak in strchr(), strstr(), substr(), chunk_split(), strtok(), addcslashes(), str_repeat(), trim().
• Fixed a possible memory corruption in substr_replace().
• Fixed SplObjectStorage unserialization problems (CVE-2010-2225).
• Fixed a possible stack exaustion inside fnmatch().
• Fixed a NULL pointer dereference when processing invalid XML-RPC requests (Fixes CVE-2010-0397, bug #51288).
• Fixed handling of session variable serialization on certain prefix characters.
• Fixed a possible arbitrary memory access inside sqlite extension. Reported by Mateusz Kocielski.

Key enhancements in PHP 5.2.14 include:

• Upgraded bundled PCRE to version 8.02.
• Updated timezone database to version 2010.5.
• Fixed bug #52238 (Crash when an Exception occured in iterator_to_array).
• Fixed bug #52237 (Crash when passing the reference of the property of a non-object).
• Fixed bug #52041 (Memory leak when writing on uninitialized variable returned from function).
• Fixed bug #51822 (Segfault with strange __destruct() for static class variables).
• Fixed bug #51552 (debug_backtrace() causes segmentation fault and/or memory issues).
• Fixed bug #49267 (Linking fails for iconv on MacOS: “Undefined symbols: _libiconv”).

To prepare for upgrading to PHP 5.3, now that PHP 5.2’s support ended, a migration guide available on https://php.net/migration53, details the changes between PHP 5.2 and PHP 5.3.

Changes with nginx 0.8.50                                        02 Sep 2010

    *) Feature: the "secure_link", "secure_link_md5", and
       "secure_link_expires" directives of the ngx_http_secure_link_module.

    *) Feature: the -q switch.
       Thanks to Gena Makhomed.

    *) Bugfix: worker processes may got caught in an endless loop during
       reconfiguration, if a caching was used; the bug had appeared in
       0.8.48.

    *) Bugfix: in the "gzip_disable" directive.
       Thanks to Derrick Petzold.

    *) Bugfix: nginx/Windows could not send stop, quit, reopen, and reload
       signals to a process run in other session.

目前官方的页面上还是RC1，国内都是RC1，俺偶然得到未放出的RC2版本，这说明flashfxp的正式版本马上就要出了，着急的朋友去软件区先睹为快吧。安装前请先读INFO.txt,本软件有patch。
