1)安装cpan：
sudo perl -MCPAN -e install Spiffy
(用此命令第一次安装任意模块时都会先把cpan装上)
2)安装perl模块：
sudo cpan install DBI
3)验证是否安装成功
perl -e 'use DBI'
（没报错即成功）
去掉 -lsocket。socket在linux中的实现位于libc中，编译时被默认包含。
在 htdocs 文件下，有 cgi 的程序，cgi 是用 perl 写的，但文件中声明的 perl 执行程序位置是错的， perl 脚本位于 /usr/bin 中（用 which perl 可以查看），所以第一行改为：
#!/usr/bin/perl -Tw
为了能够在Linux系统顺利编译并运行，这里做了如下修改。
httpd.c 的第33行
void accept_request(int);
修改为
void *accept_request(void *);
httpd.c 的第51行
void accept_request(int client)
{
char buf[1024];
...
}
修改为
void *accept_request(void* tclient)
{
int client = *(int *)tclient;
char buf[1024];
...
httpd.c 的第76行
return;
修改为
return NULL;
httpd.c 的第124行，添加
return NULL;
httpd.c 的第438 行
int namelen = sizeof(name);
修改为
socklen_t namelen = sizeof(name);
httpd.c 的第458行
int client_name_len = sizeof(client_name);
修改为
socklen_t client_name_len = sizeof(client_name);
httpd.c 的第471行修改为
if (pthread_create(&newthread , NULL, accept_request, (void*)&client_sock) != 0)
make
./httpd
（提示运行时的端口号）
浏览器输入 http://127.0.0.1:端口号

I wrote this webserver for an assignment in my networking class in 1999. We were told that at a bare minimum the server had to serve pages, and told that we would get extra credit for doing "extras." Perl had introduced me to a whole lot of UNIX functionality (I learned sockets and fork from Perl!), and O'Reilly's lion book on UNIX system calls plus O'Reilly's books on CGI and writing web clients in Perl got me thinking and I realized I could make my webserver support CGI with little trouble.
Now, if you're a member of the Apache core group, you might not be impressed. But my professor was blown over. Try the color.cgi sample script and type in "chartreuse." Made me seem smarter than I am, at any rate. :)
Apache it's not. But I do hope that this program is a good educational tool for those interested in http/socket programming, as well as UNIX system calls. (There's some textbook uses of pipes, environment variables, forks, and so on.)
One last thing: if you look at my webserver or (are you out of mind?!?) use it, I would just be overjoyed to hear about it. Please email me. I probably won't really be releasing major updates, but if I help you learn something, I'd love to know!
Happy hacking!
