1769sc-IT6I /A 本文所使用的Web Server為Boa，它是一個單任務的http服務器，源代碼開放、性能高、速度快。其工作流程如圖4所示。目前，uClinux的代碼中已經包含Boa的源代碼，在uClinux下實現Boa，需要對Boa做一些配置和修改。配置Boa包括以下幾個步驟：
（1） 打開所建立文件系統中的“／target／etc／config”文件夾中的“boa．conf’文件。
（2） 將“ChRoot”更改為“／mnt／ide0／www”，其目的是將CF卡上面的“www”文件夾作為Web Server的主文件夾。鍵入系統IP時，服務器自動解析為在此目錄內尋找名為“index．htm”的網頁，也就是本設計的主頁。
（3） 在“SeriptAlias”選項中添加命令：“ScriptAlias／mnt／ide0／www／cgi-bin／／cgi-bin／“，其目的是將前面的具有完整路徑的文件夾的地址映射為后一個文件夾，一是可以省去在地址欄內輸入地址的很多時間，方便用戶操作；二是增加了系統的保密性和安全性。其他選項可以選擇默認選項。
（4） 保存配置好的文件。當下載文件系統后，要在“／mnt／ide0／www”文件中，建立“csi-bin”目錄來存放CGI腳本文件。
3.3 CGI程序設計
CGI程序使用C語言編寫，內嵌html腳本，所以當CGI執行的時候，即可以完成對特定端口的操作，又可以將其返回的結果顯示在網頁上供監控人員查看。具體操作是：首先，CGI腳本采用GET的方式，接收Web Server解析的從網頁所傳輸過來的“QUERY_STRTING”，它代表的是用戶的監控命令。接到命令后，CGI程序將命令譯碼后傳送到串口，向現場監控模塊發送采集命令，并接受其傳回來的采集結果，并迅速傳到監控用戶所瀏覽的Web界面。需要注意的是，在編寫過CGI程序并成功編譯后，要將其移動至CF卡相關目錄，也就是上面所介紹的Boa Web Server所設置的“www／csi-bin”中，并將其后綴更改為“.cgi”，屬性改為“可執行”，這樣，Web Server才可以正確識別并執行此CGI程序。
