CentOS 5 中的 Apache (httpd-2.2.3-22.el5.centos) 与 CentOS 6 中的 Apache (httpd-2.2.15-39.el6) 之间的配置差异是什么？

我了解到后续版本解决了安全漏洞：

http://httpd.apache.org/security/vulnerabilities_22.html

据说，http://httpd.apache.org/download.html完整变更列表位于http://httpd.apache.org/[首选]/httpd/CHANGES_2.2，但 apache.org 似乎不再有可用的 CHANGES_2.2 文件。

无论如何，在没有仔细研究发行说明的情况下，是否有人曾经处理过这种升级，知道哪些配置差异会影响 CentOS httpd 版本 2.2.3-22.el5.centos 和 CentOS httpd 版本 2.2.15-39.el6 之间的变化？

答案1

那么，结果搜索 inurl：“httpd/CHANGES_2.2”Apache Web 服务器的 CHANGES_2.2 似乎已经出现在其他一些网站上：

http://supergsego.com/apache/httpd/CHANGES_2.2

看起来这些变化大部分是为了修复错误、添加新指令或消除安全问题。

从 CentOS 5 中的 Apache（httpd-2.2.3-22.el5.centos）到 CentOS 6 中的 Apache（httpd-2.2.15-39.el6）的变更并非错误修正或安全补丁，而似乎确实需要注意从版本到版本之间的变更的配置，如下所示：

  *) mod_proxy: Complete ProxyPassReverse to handle balancer URL's.  Given;
   BalancerMember balancer://alias http://example.com/foo
   ProxyPassReverse /bash balancer://alias/bar
     backend url http://example.com/foo/bar/that is now translated /bash/that
     [William Rowe]

  *) core/utils: Enhance ap_escape_html API to support escaping non-ASCII
     chars [Nick Kew]

  *) Output -M and -S dumps (modules and vhosts) to stdout instead of stderr.
     PR 42571 and PR 44266 (dup).  [Dan Poirier <poirier pobox.com>]

  *) Linux 2.0: remove support for threaded MPM's due to linuxthreads use
     of SIGUSR1 clashing with graceful restart signal. [Colm MacCarthaigh]

  *) Change the default (when not present in the config file) setting
     for UseCanonicalName to Off.
     [Joshua Slive]

  *) mod_userdir: The module no longer does any remapping unless the
     UserDir directive is present in the config file.
     [Joshua Slive]

2.1.4

  *) Massively simplify the distributed httpd.conf by removing
     many features and many directives that are at their default
     setting.  Add a selection of example config excerpts for adding
     extra features in the conf/extra/ directory.  Install the
     distributed config and the extra config examples in the
     conf/original/ directory during make install.
     [Joshua Slive, Justin Erenkrantz]
