Question

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，但我没有看到恢复数据库。

远程转储中的Mongo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

正如您可以从日志中注意到的那样，stdout表示连接到127.0.0.1但没有恢复。

请提出任何建议

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 dump文件夹，第二个是恢复转储。我发现第二个命令执行时，PWD不是一个集合，它是默认的$ 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')

这适合我。

Mongorestore在远程主机上使用paramiko
