我的openwrt学习笔记（二十九）webserver之 thttpd

thttpd - tiny/turbo/throttling HTTP server 
thttpd中是一个简单,小型,轻便,快速和安全的http服务器：
简单：它能够支持HTTP/1.1协议标准，或者超过了最低水平
小巧：它具有非常少的运行时间，因为它不fork子进程来接受新请求，并且非常谨慎的分配内存（性能对比表：http://www.acme.com/software/thttpd/benchmarks.html）
便携：它能够在大部分的类Unix系统上运行，包括FreeBSD, SunOS 4, Solaris 2, BSD/OS, Linux, OSF等等
快速：它的速度要超过主流的Web服务器（Apache, NCSA, Netscape），在高负载情况下，它要快的多
安全：它努力的保护主机不受到攻击，不中断服务器

thttpd 类似于lighttpd，对于并发请求不使用fork()来派生子进程处理，而是采用多路复用(Multiplex)技术来实现。因此效能很好。同时它还有一个特点就是基于URL的文件流量限制，这对于下载的流量控制而言是非常方便的。象Apache就必须使用插件实现，效率较thttpd低。
thttpd跟lighttpd类似，适合静态资源类的服务，比如图片、资源文件、静态HTML等等的应用，性能应该比较好，同时也适合简单的CGI应用的场合。

一.安装

# wget http://www.acme.com/software/thttpd/thttpd-2.25b.tar.gz

# tar zxvf thttpd-2.25b.tar.gz

# cd thttpd-2.25b

htpasswd.c:52:12: error: conflicting types for ‘getline’

/usr/include/stdio.h:675:20: note: previous declaration of ‘getline’ was here

htpasswd.c: In function ‘main’:

make: *** [subdirs] Error 2

修改方法：

htpasswd.c中的名称与stdio.h标准库中的getline的名称一样，所以导致了冲突。

修改的方法是到htpasswd.c中，修改getline。htpasswd.c中getline是一个static类型的函数，函数只会出现在本文件中。依次查找getline，并修改成get_line。

htpasswd.c 第52行定义

static int getline(char *s, int n, FILE *f) {

htpasswd.c 第192行调用

while(!(getline(line,MAX_STRING_LEN,f))) {

到了这里，当我输入目标板ip时，问题出现了：

403 Forbidden

The requested URL '/mul.html' resolves to a file which is marked executable but is not a CGI file; retrieving it is forbidden.

thttpd/2.25b 29dec2003

原因：由于linux文件系统的权限问题，非cgi的文件请使用chmod -x去掉其可执行权限，否则web服务器会认为它是cgi ( 比如index.html这样的文件 )

thttpd web对目录和文件的访问权限要求非常严格，在测试的时候，已经心有体会。

在目标板的/var目录下添加两个文件：

[plain] view plaincopyprint?

再次重启目标板，待进入shell界面，从主机的浏览器中输入：

[plain] view plaincopyprint?

在本人所用的调试环境下，浏览器地址栏输入：

[plain] view plaincopyprint?
