2.5 安裝 FCGI 模塊 for Perl

　　如果要使用 Perl 來撰寫 FastCGI 的程序，必須安裝 FCGI.pm 這個模塊，安裝的方法如下：

1. 下載 FCGI-0.45.tar.gz 并且解開

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

2. 編譯及安裝

$ perl Makefile.PL
$ make
$ make install

3. 測試

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

如果順利的話，應該會看到如下的結果：

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

Initial environment:

　　同樣的，如果持續結 http://localhost/fcgi-bin/echo.fpl 可以看到 Request Number 不斷增加，表示 echo.fpl 已經被激活而且持續執行著。

　　至此，一個可供執行 FastCGI 程序的網站服務器以及撰寫 FastCGI 程序的開發環境已經建置完成，接下來就只等著新的程序放上去啰。
