mongodb转储并通过管道传递到其他数据库名称 [英] mongodb dump and pipe to other db name
问题描述
Mongodb版本3.2.12.我有两个本地数据库,"base1"和"base2"
Mongodb version 3.2.12. I have two local databases, "base1" and "base2"
我想将所有数据(所有集合)从base1复制到base2,替换那里的所有内容(例如,将生产转储到开发环境时).
I want to copy all data (all collections) from base1 over to base2, replacing everything there (like when dumping production to a dev environment).
是否有任何管道命令(或其他简单方式)可以做到这一点?
Any pipe command (or other simple way) to do this?
我尝试过
mongodump --archive --db base1 | mongorestore --db base2 --archive
列出了很多将base1.collectionname写入要在stdout上存档的文件",但是没有任何内容写入base2.
lists a lot of "writing base1.collectionname to archive on stdout", but nothing gets written to base2.
我也尝试过
mongodump --db base1 --gzip --archive=/path/to/file.gz
mongorestore --db base2 --gzip --archive=/path/to/file.gz
转储有效,还原仅显示创建存档意图",完成"
Dump works, restore just says "creating intents for archive", "done"
