连接到localhost

Question

这可能是一个非常简单/明显的答案但是我已经尝试运行相同命令的以下变体来备份本地mongo数据库并且它们都通过返回而失败：

Failed: error connecting to db server: no reachable servers

这些是命令：

• mongodump --host localhost --port 27017 --db mydbname --collection mycollection

• mongodump -h localhost:27017 --db mydbname --collection mycollection -u user -p passw --out <folder path>

• mongodump -h localhost:27017 --db mydbname --collection mycollection --out <folder path>

• mongodump --port 27017 --db mydbname --collection mycollection --out <folder path>

• mongod 实例在单独的终端窗口上运行，而我全部尝试了

我在/etc/mongod.conf找不到 mongodb.conf 。我用自制软件安装了mongo。也许它与身份验证问题有关？

Answer 1

我刚遇到同样的问题，似乎在主机设置中使用127.0.0.1而不是localhost ...

喜欢：

mongodump -h 127.0.0.1:27017 -d demo

如果您使用的是复制集（例如＆＃34; myset＆＃34;），请改用：

mongodump -h myset / 127.0.0.1:27017 -d demo

希望这会有所帮助......
