一些关于安全性的配置：
考虑到 cgi-bin 的安全性问题，我们暂时将 cgi-bin 去掉。将所有 httpd.conf 中的所有关于 cgi-bin 的行加上 #.
Xiyang 的配置
我用的： mod_limitipconn, mod_expires, mod_gzip, mod_php4, mod_so, mod_access, mod_alias, mod_userdir, mod_dir, mod_autoindex, mod_status, mod_mime, mod_log_config, http_core
关于超时的问题
在我编写好所有的产品查看页面的时候，经常会出现因为超时，或者流量过大 ,apache 停止工作的问题，原因有二，一是代码的不科学性，二是 apache 的设置问题。
以下是对设置的一点改动：
代码:
# KeepAlive: Whether or not to allow persistent connections(more than
# one request per connection). Set to "Off" to deactivate.
# KeepAlive Off
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
# MaxKeepAliveRequests 0
# KeepAliveTimeout: Number of seconds to wait for the next request
# from the same client on the same connection.
# KeepAliveTimeout 0
• 记录访问者的 HTTP-REFERER 和 AGENT, 有助于统计来者是通过什么搜索引擎找到我们的网站的。 或者在原有的CustomLog行，将参数由 common 改成 combined
代码:
# If you would like to have agent and referer logfiles,
# uncomment the following directives.
CustomLog logs/referer_log referer
CustomLog logs/agent_log agent
CustomLog logs/www.domain.com-access_log combined
使用 mod_limitipconn.c 来限制 apache 的并发数
Package: http://dominia.org/djao/limit/这里的安装建议使用动态 DSO 并 patch apache2.0, 以使得 apache2.0 可以认识在代理后方的 IP 。但是要 重新编译 apache2.0, 以下是介绍。
代码：
##Instructions for building DSO with proxy tracking:
# tar xzvf httpd-2.0.39.tar.gz
# tar xzvf mod_limitipconn-0.22.tar.gz
# cd httpd-2.0.39
# patch -p1 < ../mod_limitipconn-0.22/apachesrc.diff
# ./buildconf
# ./configure --enable-so --enable-speling --enable-rewrite
--with-ssl=/usr/local/ssl --enable-forward
# make
# make install
# cd ../mod_limitipconn-0.22
# PATH=/usr/local/apache2/bin:$PATH
# make install
安装过程
# lynx http://dominia.org/djao/limit/mod_limitipconn-0.22.tar.gz
# tar -zxvf mod_limitipconn-0.22.tar.gz
# cd httpd-2.0.48
# patch -p1 < ../mod_limitipconn-0.22/apachesrc.diff
