在robomongo客户端中无法连接到mongodb的问题

我的mongodb是安装在ubuntu虚拟机上的，通过本地的robo去连接的时候总是报错，尝试了很多种方法也是无法成功。

另外同时发现在浏览器中也是无法打开mongodb

http://192.168.31.92:27017/

开始意识到并不是robo客户端的配置问题，应该是mongodb的配置上有问题的，之前看到一篇文章是mongodb的数据比较大，所以挂载到其他的盘的实现方法中，特别说明需要去掉ip绑定的问题。Network is unreachable，所以修改一下配置试试。

root@ubuntu:/home/benny# vim /etc/mongodb.conf 
# mongodb.conf

# Where to store the data.
dbpath=/var/lib/mongodb

#where to log
logpath=/var/log/mongodb/mongodb.log

logappend=true

#bind_ip = 127.0.0.1
#port = 27017

# Enable journaling, http://www.mongodb.org/display/DOCS/Journaling

# Enables periodic logging of CPU utilization and I/O wait
#cpu = true

# Turn on/off security.  Off is currently the default
#noauth = true
#auth = true

# Verbose logging output.
#verbose = true

# Inspect all client data for validity on receipt (useful for

#objcheck = true

# Enable db quota management

root@ubuntu:/home/benny# 
root@ubuntu:/home/benny# 

然后重启mongodb服务器

root@ubuntu:/home/benny# /etc/init.d/mongodb stop
Stopping mongodb (via systemctl): mongodb.service.
root@ubuntu:/home/benny# /etc/init.d/mongodb start
Starting mongodb (via systemctl): mongodb.service.

问题修复，在robo连接的问题也同样解决了。
