我有两台电脑：Ubuntu1 和 Ubuntu2。Ubuntu1 运行带有数据库 Sacred3 的 MongoDB。我想通过 ssh 从 U2 连接到 U1 并将我的实验结果存储在那里。
我尝试过但失败了： 1. 我安装了 mongo DB，创建了神圣 3，我有 ssh 密钥。我编辑/etc/mongod.conf添加：
# network interfaces
net:
port: 27017
bindIp: 0.0.0.0
然后我启用了端口转发
ssh -fN -i ~/.ssh/sacred_key-pair.pem -L 6666:localhost:27017 ubuntu@106.969.696.969//（使用正确的 ip）
所以，据我所知，如果我连接到我的 localhost:6666 它将被转发到 106.969.696.969:27017
因此，在那之后，我正在使用Sacred 框架进行实验：
python exp1.py -m localhost:6666:sacred3
这应该将实验写入远程数据库，但是我得到：
pymongo.errors.ServerSelectionTimeoutError: localhost:27017: [Errno 111] Connection refused
这让我发疯。请帮忙！
#exp1.py 的以下内容：
from sacred import Experiment
from sacred.observers import MongoObserver
ex = Experiment()
ex.observers.append(MongoObserver.create())
def compute():
summ = layer1 - layer2
return summ
