mongodb Failed: error connecting to db server: no reachable servers

I installed mongodb in Ubuntu14.04 server

在Ubuntu14.04上安装MongoDB

I was not able to connect to mongodb via "mongoimport", "mongodump", "mongostat", etc. It always show "no reachable server"

不能通过 "mongoimport", "mongodump", "mongostat"等命令连接到MongoDB，一直报错：

"no
reachable server"

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

Somehow, I was able to connect with mongo shell

但是，我可以连接到mongo shell

mongo --port 27017
MongoDB shell version: 3.0.6
connecting to: 127.0.0.1:27017/test

At first, I doubt if it cause by my iptables, so I flush all iptables rules and create rules for ALL accept, but it still same

开始时，我怀疑是我的iptables出错，所以我刷新iptables规则，为ALL accept创建规则，但还是出错。

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

I search the stackOverflow and google and someone told marked off bind_ip or set bind_ip to 0.0.0.0, I tried all but still failed.

我搜索了stackOerflow和Google，有人说把bind_ip设为0.0.0.0，但还是失败了。

Below are my mangodb config, would any one can help me to check? Thanks for your help

下面是我的配置信息，有人知道哪里出错了吗?

#where to log

A temporary workaround (worked for me) is to add the "host" param:

mongoimport --host=127.0.0.1

Update:

Updating to Mongo >= 3.0.7 should solve the issue

(Source: Colin Marshall @ mongorestore Failed: no reachable servers)

更新MongoDB到3.0.7版本以上，成功解决问题。

I tried to restore mongo from dump but failed:

mongorestore --port 27133 dump
2015-05-07T09:39:11.760+0300    Failed: no reachable servers

Although I can connect to it without any problem:

$ mongo --port 27133
MongoDB shell version: 3.0.1
connecting to: 127.0.0.1:27133/test

In a log file there is nothing special:

Update

Host

127.0.0.1

didn't
help

$ mongorestore --host=127.0.0.1 --port=27132 dump
2015-12-16T18:52:33.270+0300    Failed: no reachable servers

Although I can still connect using

mongo

command:

$ mongo --host=127.0.0.1 --port=27133
MongoDB shell version: 3.2.0
connecting to: 127.0.0.1:27133/test
> ^C

Host

0.0.0.0

didn't
help as well:

$ mongorestore --host=0.0.0.0 --port=27133 dump

I have 3.2 version of MongoDb:

$ mongorestore --version
mongorestore version: 3.2.0-rc5
git version: 6186100ad0500c122a56f0a0e28ce1227ca4fc88

anwser1：

try adding host param

mongorestore --host=127.0.0.1 --port=27133 dump

anwser2：

I have MongoDB installed through Homebrew, and was having this issue. Here are the symptoms:

These failed:

mongorestore
dump

mongorestore
dump --host=localhost

The error I got:

Failed:
error connecting to db server: no reachable servers

These worked (as a workaround):

mongorestore
dump --host=127.0.0.1

mongorestore
dump --host=0.0.0.0

This fixed the problem for me:

brew
update && brew upgrade

That updated MongoDB to 3.0.7 and now

mongorestore
dump

works without the host flag.
