使用apache的ftpserver搭建ftp服务器

不用框架的话，可以用windows自带的ftp工具搭建，不过要下载i386之类的组件。apache提供了一套ftp服务器工具。下载apache-ftpserver-1.0.6.

解压到ftpserver就行了。如果不配置的话,启动bin下的ftpd.bat就行了，浏览器输入ftp://localhost:2121就行了。

打开该文件，可以看到：

rem ----- Create CLASSPATH --------------------------------------------
set FTPD_CLASSPATH=%CLASSPATH%;%FTPD_HOME%\common\classes;
cd /d "%FTPD_HOME%\common\lib"
for %%i in ("*.jar") do call "%FTPD_HOME%\bin\appendcp.bat" "%FTPD_HOME%\common\lib\%%i"
cd /d %FTPD_HOME%

这很简单吧，看看就明白了。

如果要安全和可以增加用户，那就要配置数据库了，当然，ftpserver提供了这样的功能。

apache的ftp文件目录和配置都在res下，进入可以看到了。

# Password is "admin"
ftpserver.user.admin.userpassword=21232F297A57A5A743894A0E4A801FC3
ftpserver.user.admin.homedirectory=./res/home
ftpserver.user.admin.enableflag=true
ftpserver.user.admin.writepermission=true
ftpserver.user.admin.maxloginnumber=0
ftpserver.user.admin.maxloginperip=0
ftpserver.user.admin.idletime=0
ftpserver.user.admin.uploadrate=0
ftpserver.user.admin.downloadrate=0

ftpserver.user.anonymous.userpassword=
ftpserver.user.anonymous.homedirectory=./res/home
ftpserver.user.anonymous.enableflag=true
ftpserver.user.anonymous.writepermission=false
ftpserver.user.anonymous.maxloginnumber=20
ftpserver.user.anonymous.maxloginperip=2
ftpserver.user.anonymous.idletime=300
ftpserver.user.anonymous.uploadrate=4800
ftpserver.user.anonymous.downloadrate=4800

匿名用户和admin登录配置。

一般配置文件。

需要哪些功能，在一般配置文件增加，或者在全配置文件内放开，修改后，要进入bin目录，执行ftpd.bat res/conf/ftpd-.xx.xml才生效。

需要新增用户，就放开数据库的配置。执行：

CREATE TABLE FTP_USER (      
   userid VARCHAR(64) NOT NULL PRIMARY KEY,       
   userpassword VARCHAR(64),      
   homedirectory VARCHAR(128) NOT NULL,             
   enableflag BOOLEAN DEFAULT TRUE,    
   writepermission BOOLEAN DEFAULT FALSE,       
   idletime INT DEFAULT 0,             
   uploadrate INT DEFAULT 0,             
   downloadrate INT DEFAULT 0,
   maxloginnumber INT DEFAULT 0,
   maxloginperip INT DEFAULT 0
);

增加一个用户，增加一个ftp目录等等。
