A，安装apache服务器和fastcgi模块支持（ubuntu测试）
sudo apt-get install apache2
sudo apt-get install libapache2-mod-fastcgi
apache2的配置文件目录如下：
ciaos@ubuntu:/etc/apache2$ ll total 80 drwxr-xr-x 7 root root 4096 May 28 21:33 ./ drwxr-xr-x 93 root root 4096 May 28 21:44 ../ -rw-r--r-- 1 root root 8346 Feb 7 2012 apache2.conf drwxr-xr-x 2 root root 4096 May 28 21:32 conf.d/ -rw-r--r-- 1 root root 1322 Feb 7 2012 envvars -rw-r--r-- 1 root root 0 May 28 21:32 httpd.conf -rw-r--r-- 1 root root 31063 Feb 7 2012 magic drwxr-xr-x 2 root root 4096 May 28 21:36 mods-available/ drwxr-xr-x 2 root root 4096 May 28 21:36 mods-enabled/ -rw-r--r-- 1 root root 750 Feb 7 2012 ports.conf drwxr-xr-x 2 root root 4096 May 28 21:58 sites-available/ drwxr-xr-x 2 root root 4096 May 28 21:58 sites-enabled/
配置fastcgi目录，只需要修改sites-enabled/000-default文件添加fastcgi的目录结构
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ScriptAlias /fcgi-bin/ /var/lib/apache2/fastcgi/ <Directory "/var/lib/apache2/fastcgi"> AllowOverride None Options FollowSymLinks Order allow,deny Allow from all SetHandler fastcgi-script </Directory>
重启apache服务器如下：
sudo apachectl -k restart
B，接下来写fastcgi程序测试（用C来测试）
1，安装fastcgi库
make的时候如果出现“error: ‘EOF‘ was not declared in
this scope”错误，则在出错文件加上#include <stdio.h>
2，编辑个简单的fastcgi程序
#include <fcgi_stdio.h> int main() { int count = 0; while(FCGI_Accept() >= 0) { printf("Content-type: text/html\r\n"); printf("\r\n"); printf("Hello world!<br>\r\n"); printf("Request number %d.", count++); } return 0; }
3，编译并放到apache的cgi和fcgi目录下测试
gcc sim.c -lfcgi -o test.cgi cp test.cgi /usr/lib/cgi-bin/ 访问 http://192.168.1.108/cgi-bin/test.cgi , 每次打印Request number都是0 gcc sim.c -lfcgi -o test.fcgi cp test.fcgi /var/lib/apache2/fastcgi/ 访问 http://192.168.1.108/cgi-bin/test.fcgi , 每次打印Request number都会递增
附：如果ldd找不到依赖库，三种方法如下
1，export
LD_LIBRARY_PATH=/usr/local/lib/
2，直接把so文件拷贝到/lib/目录下，这个目录一般都是
3，/etc/ld.so.conf添加响应目录,
/sbin/ldconfig –v更新
