我在Ubuntu 14.04服务器上安装mongodb
我无法通过“mongoimport”，“mongodump”，“mongostat”等连接到mongodb。它始终显示“无法访问的服务器”
mongoimport --db test --collection restaurants --drop --file dataset.json
2015-08-25T13:08:29.802+0800 [........................] test.restaurants 0.0 B/11.3 MB (0.0%)
2015-08-25T13:08:30.306+0800 Failed: error connecting to db server: no reachable servers
2015-08-25T13:08:30.306+0800 imported 0 documents
不知何故，我能够连接mongo shell
mongo --port 27017
MongoDB shell version: 3.0.6
connecting to: 127.0.0.1:27017/test
起初，我怀疑它是否由我的iptables引起，所以我清除所有iptables规则并为ALL接受创建规则，但它仍然相同
sudo iptables -S
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-A INPUT -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A FORWARD -j ACCEPT
-A OUTPUT -j ACCEPT
-A OUTPUT -o lo -j ACCEPT
我搜索stackOverflow和google，有人告诉标记为bind_ip或将bind_ip设置为0.0.0.0，我尝试了所有但仍然失败。
下面是我的mangodb配置，任何人都可以帮我查一下吗？谢谢你的帮助

一个临时的解决方法是将host param添加到你的mongoimport调用中，让mongo知道主机是你自己的机器（127.0.0.1）：
mongoimport --host=127.0.0.1
您的案例中的完整命令是：
mongoimport --host=127.0.0.1 \
--db test --collection restaurants --drop --file dataset.json

更新：
更新到Mongo> = 3.0.7应该可以解决问题
（来源：Colin Marshall @ mongorestore Failed: no reachable servers）
更新2：
看来Bug is still happening for some users。
还有一个开放的JIRA问题here。
（来源：James Chien @ this question thread）
更新3：
在某些情况下，这可能是由Mongo作为ReplicaSet运行引起的。为了解决这个问题，据我所见，可以禁用ReplicaSet功能或重置它。看到：

我找到了这个链接的答案https://jira.mongodb.org/browse/TOOLS-620它似乎是一个尚未解决的mongodb工具bug。不确定是否有人知道最新工具是否已解决问题？
顺便说一下，我卸载了mongodb-tools 3.x并重新安装到2.6.0解决了这个问题
sudo apt-get purge mongodb-org-tools
echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
sudo apt-get update
sudo apt-get install -y mongodb-org-tools=2.6.0
mongoimport --db test --collection restaurants --drop --file dataset.json

完整命令：
mongoimport --host=127.0.0.1 -d testdb -c testc --file test.txt
如果您已经通过自制软件安装了mongodb，那么您只需启动mongodb即可
brew services start mongodb
然后通过访问shell
mongo
你可以关闭你的数据库
brew services stop mongodb
有更多选择
brew info mongodb
提供选项主机和端口
mongoimport --host X.X.X.X --port 27017 --db dbName --collection collectionName --file fileName.json --jsonArray
mongorestore --db <thedb> --host=127.0.0.1 --port=<port> --drop path/db
