来自远程服务器的Mongodump [英] Mongodump from remote server

问题描述

我们最近将一些数据移植到了MongoDB上，现在正在研究运行日常备份(最好是从cron作业)，并将其中一个备份还原到辅助mongo数据库.

We recently ported some data over to MongoDB and are now looking into running daily backups, preferably from a cron job, and restore one of the backups to a secondary mongo database.

我们的系统设置如下:

• 服务器1:开发mongo数据库
• 服务器2:两个mongo数据库，一个用于暂存数据，另一个用于生产
• 服务器3:是我们从中运行所有cron作业/批处理脚本的地方.

我检查了mongo文档，并登录了我们的cron作业服务器，并尝试运行以下命令:(出于安全性考虑，更改了用户名，主机和密码，我实际上没有连接到本地主机)

I checked the mongo docs, and logged into our cron job server and tried to run the following command: (username, host, and password changed for security, I'm not actually connecting to localhost)

mongodump --host 127.0.0.1/development --port 27017 --username user --password pass --out /opt/backup/mongodump-2013-10-07-1

我收到以下消息:

我确认可以使用mongo -u -p ip/development

我们的最终目标是从生产数据库中转储数据并将其存储在登台数据库中.如果有所不同，这两个数据库都位于同一个盒子上，但是出于测试目的，我只是尝试备份开发测试数据.

Our ultimate goal will be to dump the data from the production database and store it in the staging database. These two databases are both located on the same box, if that makes a difference, but for testing purposes I am just trying to get a backup of development test data.

推荐答案

mongo客户端可以解析 MongoDB连接字符串URI ，因此您可以传递单个连接字符串URI，而不是单独指定所有连接参数.

mongo client can parse MongoDB connection string URI, so instead of specifying all connection parameters separately you may pass single connection string URI.

在您的情况下，您尝试将连接URI作为host传递，但是127.0.0.1/development不是有效的主机名.这意味着您应该与host分开指定database参数:

In your case you're trying to pass connection URI as a host, but 127.0.0.1/development is not a valid host name. It means you should specify database parameter separately from the host:

mongodump --host 127.0.0.1 -d development --port 27017 --username user --password pass --out /opt/backup/mongodump-2013-10-07-1
