在Unix/Linux安装FastCGI起来比较复杂。现在就在这里讲一下，在Unix/Linux系统下，Perl语言，Apache服务器环境下安装FastCGI。
Apache里FCGI的模块：
1、下载http://www.fastcgi.com/dist/mod_fastcgi.tar.gz
2、解压apache安装文件。解压fastcgi安装文件到apache下的/src/modules/fas tcgi目录
3、设定Apache加入mod_fastcgi模块：
./configure --activate-module=src/modules/fastcgi/libfastcgi.a --enabl e-module=info --enable-shared=info
4、编译及安装
$ make
$ make install
5、查看编译出来的执行文件是否含有 mod_fastcgi 模块：
$ apacherunpath/httpd -l
Compiled-in modules:
http_core.c
...
mod_fastcgi.c
...
6、加入使用 mod_fastcgi 的相关设定
编辑httpd.conf加入AddHandler fastcgi-script .fcg .fpl这一行建立youwwwpath/fcgi-bin目录，设置/fcgi-bin/目录指到youwwwpath/fcgi-bin /在httpd.conf加入ScriptAlias /fcgi-bin/ /usr/local/www/fcgi-bin/
7、检测语法错误
$ /apachepath/apachectl configtest
Syntax OK --系统显示
8、重新激活阿帕契服务器，让新设定生效：
$ /usr/local/apache/sbin/apachectl graceful
/usr/local/apache/bin/apachectl graceful: httpd gracefully restarted --系统显示
PERL的FCGI模块：
1、首先我们安装FastCGI在Perl下的模块。最新版本在http://www.fastcgi.com里下载。
最新版本：FCGI-0.56.tar.gz
2、下载 FCGI-0.45.tar.gz 并且解开
$ gunzip -c FCGI-0.56.tar.gz | tar xvf -
3、编译及安装
$ perl Makefile.PL
$ make
$ make install
4、测试
$ cp echo.fpl {你www里Fastcgi所在目录}
$ lynx {你www里echo.fpl的地址}
如果顺利的话，应该会看到如下的结果：
FastCGI echo (Perl)

最后，给大家一个fastcgi编程的例子：
#!/usr/local/bin/perl
use CGI::Fast;
my $counter = 0;
while (my $cgi = new CGI::Fast) {
print("Content-type: text/html\n\n");
print("We have served $counter requests");
$counter++;
}
