我正在尝试使用 python 脚本从本地恢复远程机器中的 mongodump。我的脚本运行良好，但我没有看到恢复的数据库。

Mongo 远程转储

/root/dump

我的剧本

#!/usr/bin/python

import paramiko
import sys
import os

ssh = paramiko.SSHClient()
ssh.connect('192.168.3.54',username='xx',password='xx')
ssh.exec_command('cd /root')
stdin,stdout,stderr = ssh.exec_command('mongorestore --db mydatabase')
print stdout.read()
ssh.close()

从终端登录

正如您从日志中看到的那样，标准输出显示连接到 127.0.0.1 但没有恢复。

请有任何建议

我发现了问题所在。我的脚本中有两个 ssh_exec 语句，第一个是将我的 PWD 定位到 mongo 转储文件夹，第二个是恢复转储。我发现执行第二个命令时，PWD 不是一组，而是默认的 $HOME 目录。所以我改变了我的脚本，将两个 exec 语句合并为一个

stdin,stdout,stderr = ssh.exec_command('mongorestore --db mydatabase /root/dump')

这对我有用。
