python FTP服务器实现（Python3）

创建一个ftp.py文件（linux环境），插入以下代码:

from pyftpdlib.authorizers import dummyauthorizer
from pyftpdlib.handlers import ftphandler
from pyftpdlib.servers import ftpserver

# 实例化dummyauthorizer来创建ftp用户
authorizer = dummyauthorizer()
# 参数：用户名，密码，目录，权限
authorizer.add_user('test', '12345', '/root/ftp', perm='elradfmwmt')
authorizer.add_user('tese1', '12345', '/root/ftp', perm='elradfmwmt')
# 匿名登录
# authorizer.add_anonymous('/home/nobody')

handler = ftphandler
handler.authorizer = authorizer

# 参数：ip，端口，handler
server = ftpserver(('172.31.8.88', 21), handler)
server.serve_forever()

###### 文件保存
:wq 保存文件

###### 运行：

root@k8s-node1 ~]# nohup python3 ftp.py &
[1] 1737
[root@k8s-node1 ~]# nohup: 忽略输入并把输出追加到"nohup.out"
[root@k8s-node1 ~]# root@k8s-node1 ~]# tail -f nohup.out
