工作问题原因有 2是代码不科学性 2是 apache 设置问题
　　
　　以下是对设置点改动:
　　
　　代码:
　　# KeepAlive: Whether or not to allow persistent connections(more than
　　# _disibledevent=/usr/local/apache2/bin:$PATH
　　# make
　　----------------------------------------------------------------------
　　Libraries have been ed in:
　　/usr/local/apache2/modules
　　If you ever happen to want to link against ed libraries
　　in a given directory, LIBDIR, you must either use libtool, and
　　specy the full pathname of the library, or use the `-LLIBDIR'
　　flag during linking and do at least one of the following:
　　- add LIBDIR to the `LD_LIBRARY_PATH' environment　variable
　　during execution
　　- add LIBDIR to the `LD_RUN_PATH' environment variable
　　during linking
　　- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
　　- have your system administrator add LIBDIR to `/etc/ld.so.conf'
　　See any operating system documentation about shared libraries for
　　more information, such as the ld(1) and ld.so(8) manual pages.
　　----------------------------------------------------------------------
　　chmod 755 /usr/local/apache2/modules/mod_limitipconn.so
　　[activating module `limitipconn' in /usr/local/apache2/conf/httpd.conf]　
　　
　　检查 httpd.conf 文件发现增加了下行
　　
　　代码:
　　LoadModule limitipconn_module modules/mod_limitipconn.so　
　　
　　同时需要设置以下参数在 httpd.conf 中 , 也可以在单个虚拟服务器中
　　
　　代码:
　　ExtendedStatus On
　　# Only needed the module is compiled as a DSO
　　LoadModule limitipconn_module lib/apache/mod_limitipconn.so
　　<IfModule mod_limitipconn.c>
　　<Location /somewhere>
　　MaxConnPerIP 3
　　# exempting images from the connection limit is often　a good
