Python拷贝脚本到远程服务器并执行

1. 拷贝run.sh到server1的/home/user下

scp /user/run.sh username@server1:/home/user

2. 拷贝a文件夹到server1的/home/user下

scp -r /user/a username@server1:/home/user  

此时需要输入密码，通过os.system加expect实现

def remoteShellSCP():
    scp_put = '''  
            spawn scp -r %s %s@%s:%s  
            expect "*(yes/no*)?" {  
                send "yesr" 
            } 
            expect "Password:" {
                send "%sr"
            }
            expect eof  
            exit
        '''
    os.system("echo '%s' > scp_put.cmd" % (scp_put % (script_path, username,
                                               server, path2, password)))
    os.system("expect scp_put.cmd")
    os.system("rm scp_put.cmd")

其中：

1）expect里面的内容需要和实际完全一致，可以用*补全

2）os.system("echo '%s' > scp_put.cmd" % (scp_put %()))

将scp_put写入到scp_put.cmd

3）os.system("expect scp_put.cmd")

执行scp_put.cmd

def run_script():
        """
        run script on server by:
        1. connect server
        2. run script
        3. delete script
        :param:
        :return:
        """
        for server in servers:
            s = paramiko.SSHClient()
            try:
                logging.info("Server: {}".format(server))
                s.set_missing_host_key_policy(paramiko.AutoAddPolicy())
                s.connect(hostname=server,username=username,password=password)

                logging.info("Run run.sh ")
                stdin, stdout, stderr = s.exec_command("sudo bash /user/a/run.sh")
                message = stdout.read().decode("utf8")
                logging.info("Message: n{}".format(message))

                stdin, stdout, stderr = s.exec_command("sudo rm -rf /user/a")

            except Exception as e:
                print(e)

            finally:
                s.close()
        return

注：exec_command 里面每一个语句是独立的，每次会回到默认路径下执行，所以每次要加上sudo，和完整路径。
