#Boa v0.94 configuration file

#File format has not changed from 0.93

#File format has changed little from 0.92

#version changes are noted in the comments

#

#The Boa configuration file is parsed with a lex/yacc or flex/bison

#generated parser.  If it reports an error, the line number will be

#provided; it should be easy to spot.  The syntax of each of these

#rules is very simple, and they can occur in any order.  Where possible

#these directives mimic those of NCSA httpd 1.3; I saw no reason to

#introduce gratuitous differences.

#The "ServerRoot" is not in this configuration file.  It can becompiled

#into the server (see defines.h) or specified on the command line with

#the -c option, for example:

#

#boa -c /usr/local/boa

#Port: The port Boa runs on.  The default port for http servers is 80.

#If it is less than 1024, the server must be started as root.

Port80

#Listen: the Internet address to bind(2) to.  If you leave it out,

#it takes the behavior before 0.93.17.2, which is to bind to all

#addresses (INADDR_ANY).  You only get one "Listen" directive,

#if you want service on multiple IP addresses, you have three choices:

#   1. Run boa without a "Listen" directive

#      a. All addresses are treated the same; makes sense if theaddresses

#         are localhost, ppp, and eth0.

#      b. Use the VirtualHost directive below to point requeststo different

#         files.  Should be good for a very largenumber of addresses (web

#         hosting clients).

#   2. Run one copy of boa per IP address, each has its ownconfiguration

#      with a "Listen" directive.  No big deal upto a few tens of addresses.

#      Nice separation between clients.

#The name you provide gets run through inet_aton(3), so you have to use dotted

#quad notation.  This configuration is too important to trust some DNS.

#Listen192.68.0.5

# User: The name or UID the server should run as.

#Group: The group name or GID the server should run as.

User nobody

Group0

#ServerAdmin: The email address where server problems should be sent.

#Note: this is not currently used, except as an environment variable

#for CGIs.

#ServerAdminroot@localhost

#ErrorLog: The location of the error log file. If this does not start

#with /, it is considered relative to the server root.

#Set to /dev/null if you don't want errors logged.

#If unset, defaults to /dev/stderr

#ErrorLog/var/log/boa/error_log

#Please NOTE: Sending the logs to a pipe ('|'), as shown below,

# is somewhat experimental and might fail under heavy load.

#"Usual libc implementations of printf will stall the whole

# process if the receiving end of a pipe stops reading."

#ErrorLog"|/usr/sbin/cronolog --symlink=/var/log/boa/error_log/var/log/boa/error-%Y%m%d.log"

#AccessLog: The location of the access log file. If this does not

#start with /, it is considered relative to the server root.

#Comment out or set to /dev/null (less effective) to disable

#Access logging.

AccessLog/var/log/boa/access_log

#Please NOTE: Sending the logs to a pipe ('|'), as shown below,

# is somewhat experimental and might fail under heavy load.

#"Usual libc implementations of printf will stall the whole

# process if the receiving end of a pipe stops reading."

#AccessLog "|/usr/sbin/cronolog --symlink=/var/log/boa/access_log/var/log/boa/access-%Y%m%d.log"

#UseLocaltime: Logical switch.  Uncomment to use localtime

#instead of UTC time

#UseLocaltime

#VerboseCGILogs: this is just a logical switch.

# It simply notes the start and stop times of cgis in the error log

#Comment out to disable.

#VerboseCGILogs

#ServerName: the name of this server that should be sent back to

#clients if different than that returned by gethostname + gethostbyname

ServerNamewww.your.org.here

#VirtualHost: a logical switch.

#Comment out to disable.

#Given DocumentRoot /var/www, requests on interface 'A' or IP 'IP-A'

#become /var/www/IP-A.

#Example: http://localhost/ becomes/var/www/127.0.0.1

#

#Not used until version 0.93.17.2.  This "feature" also breakscommonlog

#output rules, it prepends the interface number to each access_log line.

#You are expected to fix that problem with a postprocessing script.

#VirtualHost

#DocumentRoot: The root directory of the HTML documents.

#Comment out to disable server non user files.

DocumentRoot/web

#UserDir: The name of the directory which is appended onto a user's home

#directory if a ~user request is recieved.

UserDirpublic_html

#DirectoryIndex: Name of the file to use as a pre-written HTML

#directory index.  Please MAKE AND USE THESE FILES.  On the

#fly creation of directory indexes can be _slow_.

#Comment out to always use DirectoryMaker

DirectoryIndexindex.html

#DirectoryMaker: Name of program used to create a directory listing.

#Comment out to disable directory listings.  If both this and

#DirectoryIndex are commented out, accessing a directory will give

#an error (though accessing files in the directory are still ok).

#DirectoryMaker/usr/lib/boa/boa_indexer

#DirectoryCache: If DirectoryIndex doesn't exist, and DirectoryMaker

#has been commented out, the the on-the-fly indexing of Boa can be used

#to generate indexes of directories. Be warned that the output is

#extremely minimal and can cause delays when slow disks are used.

#Note: The DirectoryCache must be writable by the same user/group that

#Boa runs as.

#DirectoryCache /var/spool/boa/dircache

#KeepAliveMax: Number of KeepAlive requests to allow per connection

#Comment out, or set to 0 to disable keepalive processing

KeepAliveMax1000

#KeepAliveTimeout: seconds to wait before keepalive connection times out

KeepAliveTimeout10

#MimeTypes: This is the file that is used to generate mime type pairs

#and Content-Type fields for boa.

#Set to /dev/null if you do not want to load a mime types file.

#Do *not* comment out (better use AddType!)

MimeTypes/etc/mime.types

#DefaultType: MIME type used if the file extension is unknown, or there

#is no file extension.

DefaultTypetext/plain

#CGIPath: The value of the $PATH environment variable given to CGI progs.

CGIPath/bin:/usr/bin:/usr/local/bin

#SinglePostLimit: The maximum allowable number of bytes in

#a single POST.  Default is normally 1MB.

#AddType: adds types without editing mime.types

#Example: AddType type extension [extension ...]

#Uncomment the next line if you want .cgi files to execute from anywhere

#AddTypeapplication/x-httpd-cgi cgi

#Redirect, Alias, and ScriptAlias all have the same semantics -- they

#match the beginning of a request and take appropriate action.  Use

#Redirect for other servers, Alias for the same server, and ScriptAlias

#to enable directories for script execution.

#Redirect allows you to tell clients about documents which used to exist in

#your server's namespace, but do not anymore. This allows you to tell the

#clients where to look for the relocated document.

#Example: Redirect /bar http://elsewhere/feh/bar

#Aliases: Aliases one path to another.

#Example: Alias /path1/bar /path2/foo

#Alias/doc /usr/doc

#ScriptAlias: Maps a virtual path to a directory for serving scripts

#Example: ScriptAlias /htbin/ /www/htbin/

ScriptAlias/cgi-bin/ /web/cgi-bin/

2. 修改 boa.c  
对于boa-0.94.13版本的
第 225~227 行的程序直接删掉

3 makefile 文件的修改
CC = arm-linux-gcc
CPP = arm-linux-gcc

之后就用make命令生成boa可执行文件

4 开发板所需文件

/web/cgi-bin/        /web/index.html
/bin/boa   (boa 是经交叉编译后生成的可执行程序）
/etc/boa/boa.conf     (boa文件没有需要创建，boa.conf是经相关设置后的文件）
/etc/mime.types    (原系统下/etc下有该文件，直接复制过来
记得修改文件读写执行权限

直接就可与运行boa ,然后可以通过网络访问

favicon.ico  没发现，就是随便找个ico文件改名为favicon.ico 然后放在 /web目录下

让boa服务能开机运行在/etc/init.d/rcS 目录下  加上  /bin/boa &

记得加上静态 –static
