2.5 安装 FCGI 模块 for Perl

　　如果要使用 Perl 来撰写 FastCGI 的程序，必须安装 FCGI.pm 这个模块，安装的方法如下：

1. 下载 FCGI-0.45.tar.gz 并且解开

$ gunzip -c FCGI-0.45.tar.gz | tar xvf -

2. 编译及安装

$ perl Makefile.PL
$ make
$ make install

3. 测试

$ cp echo.fpl /usr/local/www/fcgi-bin
$ lynx http://localhost/fcgi-bin/echo.fpl

如果顺利的话，应该会看到如下的结果：

FastCGI echo (Perl)
Request number 1
No data from standard input.

Initial environment:

　　同样的，如果持续结 http://localhost/fcgi-bin/echo.fpl 可以看到 Request Number 不断增加，表示 echo.fpl 已经被激活而且持续执行着。

　　至此，一个可供执行 FastCGI 程序的网站服务器以及撰写 FastCGI 程序的开发环境已经建置完成，接下来就只等着新的程序放上去啰。
