1、使用pexpect实现文件及文件夹同步

使用pexpect可以实现通过编程方式使用帐户和密码登陆，之后通过拷贝scp命令来进行文件和目录的复制同步。代码如下

import pexpect

def doScp(username='root', 
    aim_ip='192.168.31.11', 
    password='Aa123456',
    source_file_path='/home/root/cjavapy',
    aim_file_path='/home/',
    port=22):
    password_key = '.*assword.*'
    mkdir = f'ssh {username}@{aim_ip} "if [ ! -d aim_file_path ];then mkdir -p {aim_file_path}; fi"'
    command = f'if [ ! -d aim_file_path ];then mkdir -p {aim_file_path}; fi"&&scp {source_file_path}  {username}@{aim_ip}:{aim_file_path}'
    print("执行指令: ", command)
    try:
        execute = pexpect.spawn(mkdir)
        execute.expect(password_key)
        execute.sendline(password)
        execute.expect(pexpect.EOF)
        execute = pexpect.spawn(command)
        execute.expect(password_key)
        execute.sendline(password)
        execute.expect(pexpect.EOF)
        print("拷贝成功")
    except:
        print("拷贝失败")

def executeRemoteCommand(host_list,source_file_path, aim_file_path):
    import threading
    thread_list = []
    for ip, username, password in host_list:
        thread = threading.Thread(target = doScp, args = (username,ip,password,source_file_path,aim_file_path))
        thread_list.append(thread)#将生成的线程添加到列表里
    for t in thread_list:
        t.start() #开始执行线程
    for t in thread_list:
        t.join() #挂起线程，到所有线程结束

if __name__ == '__main__':
    executeRemoteCommand([('192.168.31.21','root','Aa123456')],'/home/cjavapy','/home/')

2、使用paramiko实现文件及文件夹同步

参考文档：https://github.com/mike-zhang/autoSync

1）default.xml配置文件说明

2）安装paramiko和watchdog

pip install paramiko
pip install watchdog

3）使用方法

python autoSync.py default.xml

注意：如果有多台服务器，可以新建多个xml配置文件，然后分别执行python autoSync.py config.xml来执行同步。
