利用apache ftpserver搭建ftp服务器

操作环境：

win2012r2 x64 datacenter

Apache FtpServer 1.2.0

Java SE Development Kit 8u333

commons-dbcp2-2.9.0.jar

commons-pool2-2.11.1.jar

mysql server 8.0.29

mysql-connector-java-8.0.29.jar

sqlite

sqlite-jdbc-3.36.0.3.jar

如下图：

一、usermanager采用文件形式管理xml示例如下

<?xml version="1.0" encoding="UTF-8"?>

            </ssl>
    </nio-listener>
  </listeners>
  <file-user-manager file="./res/conf/users.properties" />
</server>

二、usermanager采用mysql数据库管理用户时，ftpd-mysql.xml示例如下

目前数据库管理用户时采用的明文存储，salted和md5的方式没有测试成功，如有测试成功的朋友请指导一下。

    <db-user-manager encrypt-passwords="clear">

            </beans:bean>
        </data-source>
        <insert-user>INSERT INTO FTP_USER (userid, userpassword,
            homedirectory, enableflag, writepermission, idletime, uploadrate,
            downloadrate) VALUES ('{userid}', '{userpassword}',
            '{homedirectory}',
            {enableflag}, {writepermission}, {idletime},
            {uploadrate},
            {downloadrate})
        </insert-user>
        <update-user>UPDATE FTP_USER SET
            userpassword='{userpassword}',homedirectory='{homedirectory}',enableflag={enableflag},writepermission={writepermission},idletime={idletime},uploadrate={uploadrate},downloadrate={downloadrate}
            WHERE userid='{userid}'
        </update-user>
        <delete-user>DELETE FROM FTP_USER WHERE userid = '{userid}'
        </delete-user>
        <select-user>SELECT userid, userpassword, homedirectory,
            enableflag, writepermission, idletime, uploadrate, downloadrate,
            maxloginnumber, maxloginperip FROM
            FTP_USER WHERE userid = '{userid}'
        </select-user>
        <select-all-users>
            SELECT userid FROM FTP_USER ORDER BY userid
        </select-all-users>
        <is-admin>SELECT userid FROM FTP_USER WHERE userid='{userid}'
            AND
            userid='admin'
        </is-admin>
        <authenticate>SELECT userpassword from FTP_USER WHERE
            userid='{userid}'
        </authenticate>
    </db-user-manager>
</server>

注意：org.apache.commons.dbcp2.BasicDataSource，看最新的commons.dbcp命名空间和1.x版本有区别

三、usermanager采用Sqlite数据库管理用户时，ftpd-sqlite.xml示例如下

        <insert-user>INSERT INTO FTP_USER (userid, userpassword,
            homedirectory, enableflag, writepermission, idletime, uploadrate,
            downloadrate) VALUES ('{userid}', '{userpassword}',
            '{homedirectory}',
            {enableflag}, {writepermission}, {idletime},
            {uploadrate},
            {downloadrate})
        </insert-user>
        <update-user>UPDATE FTP_USER SET
            userpassword='{userpassword}',homedirectory='{homedirectory}',enableflag={enableflag},writepermission={writepermission},idletime={idletime},uploadrate={uploadrate},downloadrate={downloadrate}
            WHERE userid='{userid}'
        </update-user>
        <delete-user>DELETE FROM FTP_USER WHERE userid = '{userid}'
        </delete-user>
        <select-user>SELECT userid, userpassword, homedirectory,
            enableflag, writepermission, idletime, uploadrate, downloadrate,
            maxloginnumber, maxloginperip FROM
            FTP_USER WHERE userid = '{userid}'
        </select-user>
        <select-all-users>
            SELECT userid FROM FTP_USER ORDER BY userid
        </select-all-users>
        <is-admin>SELECT userid FROM FTP_USER WHERE userid='{userid}'
            AND
            userid='admin'
        </is-admin>
        <authenticate>SELECT userpassword from FTP_USER WHERE
            userid='{userid}'
        </authenticate>
    </db-user-manager>
</server>

注意：commons的jar包还保留着，多了个操作sqlitejdbc的jar包，下载地址：GitHub - xerial/sqlite-jdbc: SQLite JDBC Driver

四、解决ftpd.exe在64位windows系统启动失败的问题

需下载tomcat包，目前测试的这个版本可行tomcat-7 v7.0.109 (apache.org)

放入apache ftpserver bin目录里替换原有的ftpd.exe

这样安装为服务的时候就可以正常启动了

五、python操作sqlite的ftp.db管理（增加删除）用户

自己搞了个python脚本，采用了sqlalchemy来操作数据库

from sqlalchemy import create_engine
from sqlalchemy import MetaData,Table,Column,Boolean,Integer,String
import os

engine=create_engine('sqlite:///ftp.db')
conn=engine.connect()

metadata=MetaData()

ftpusers=Table('FTP_USER',metadata,
    Column('userid',String(64),primary_key=True),
    Column('userpassword',String(64),nullable=False),
    Column('homedirectory',String(128),nullable=False),
    Column('enableflag',Boolean(),default=True),
    Column('writepermission',Boolean(),default=True),
    Column('idletime',Integer(),default=0),
    Column('uploadrate',Integer(),default=0),
    Column('downloadrate',Integer(),default=0),
    Column('maxloginnumber',Integer(),default=0),
    Column('maxloginperip',Integer(),default=0)
)

metadata.create_all(engine)

def addgeneraluser():

	deluser = ftpusers.delete().where(ftpusers.c.userid=="nic")
	rs = conn.execute(deluser)

	dirname="./files/alluser"
	if not os.path.exists(dirname):
		os.mkdir(dirname)

	ins=ftpusers.insert().values(
		userid="nic",
		userpassword="123321",
		homedirectory=dirname,
		writepermission=0,
		maxloginnumber=1
	)

	result=conn.execute(ins)

def addadmin():
	deladmin = ftpusers.delete().where(ftpusers.c.userid=="admin")
	rs = conn.execute(deladmin)

	ins=ftpusers.insert().values(
		userid="admin",
		userpassword="123456",
		homedirectory="./files",
		writepermission=1
	)

	result=conn.execute(ins)

def getusers():
	sel=ftpusers.select()
	rs=conn.execute(sel)
	print(rs.fetchall())
	
addgeneraluser()
getusers()

可以方便的增加用户了，generaluser只读权限只能同时登录一个，admin权限可读写，不限制。
