【简单学习】用python搭建本地局域网ftp服务器

状态：好饿啊
系统：宿主机为win10，VMware为CentOS8
条件：ftp服务器搭建在CentOS8中，已安装python3
目标：使win10能通过CentOS8的IP地址访问上面的ftp服务器

安装pyftpdlib：

pip install pyftpdlib

或者

pip3 install pyftpdlib

具体情况看你的设置，我用的pip3

进入需要共享的目录

输入

python3 -m pyftpdlib

或者

python -m pyftpdlib

具体情况看设置，我用的python3
出现下图，进入虚拟机浏览器输入ftp://127.0.0.1:2121就能看见共享目录下的文件了，点击可以下载

使局域网可访问

编写一个python脚本，输入如下代码

 -*- coding:utf-8 -*-

import os
from pyftpdlib.authorizers import DummyAuthorizer
from pyftpdlib.handlers import FTPHandler
from pyftpdlib.servers import FTPServer
 
 
def main():
    # Instantiate a dummy authorizer for managing 'virtual' users
    authorizer = DummyAuthorizer()
 
    # Define a new user having full r/w permissions and a read-only
    # anonymous user
    authorizer.add_user('user', '12345', '.', perm='elradfmwM')
    # authorizer.add_anonymous(os.getcwd())
 
    # Instantiate FTP handler class
    handler = FTPHandler
    handler.authorizer = authorizer
 
    # Define a customized banner (string returned when client connects)
    handler.banner = "pyftpdlib based ftpd ready."
 
    # Specify a masquerade address and the range of ports to use for
    # passive connections.  Decomment in case you're behind a NAT.
    #handler.masquerade_address = '151.25.42.11'
    #handler.passive_ports = range(60000, 65535)
 
    # Instantiate FTP server class and listen on 0.0.0.0:2121
    address = ('192.168.153.132', 2121)
    server = FTPServer(address, handler)
 
    # set a limit for connections
    server.max_cons = 256
    server.max_cons_per_ip = 5
 
    # start ftp server
    server.serve_forever()
 
if __name__ == '__main__':
    main()

第一个箭头：设置了用户名密码，可以去掉然后把下面一行注释取消，就能匿名登陆了
第二个箭头：换成你自己虚拟机中的ip，端口默认为2121，可以自己设置

关闭防火墙

查看防火墙状态

firewall-cmd --state

停止防火墙

systemctl stop firewalld.service

运行脚本

在宿主机win10上访问ftp服务器

OK啦，退出ftp按ctrl-C就好啦
怎么让它一直运行我还没试，但目前就到此为止吧
噜啦啦啦啦啦
