Cannot connect to mongodb using machine ip

Question

Installed Mongo using homebrew. If I type mongo on shell, it gets connected to test. But when I type the ip address

Answer 1

I just tested this on my Mac with Homebrew, works fine if you change the bind address. I suspect you probably just didn't get the config for bind correct?

Just so we have all the information, can you paste the output of ifconfig please?

By default, MongoDB should listen on all interfaces, you shouldn't need to change the configuration, however, the Homebrew setup seems to override this (/usr/local/etc/mongod.conf):

# Only accept local connections
bind_ip = 127.0.0.1

Please kill MongoDB and run this (note the -v):

$ mongod --bind_ip 0.0.0.0 -v
warning: bind_ip of 0.0.0.0 is unnecessary; listens on all ips by default
all output going to: /usr/local/var/log/mongodb/mongo.log

Just paste your output for that please?

And then just try:

$ mongo --host 192.168.43.2 --verbose
MongoDB shell version: 2.4.6

Obviously replace it with your IP address. Let us know how that goes.

Answer 2

For me I replaced the bindIp with bindIpAll: true (see http://docs.mongodb.org/manual/reference/configuration-options/ for details).

This is the content of my mongod.conf file.

# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# Where and how to store data.
storage:
  dbPath: /var/lib/mongodb
  journal:
    enabled: true
#  engine:
#  mmapv1:
#  wiredTiger:

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

# network interfaces
net:
  port: 27017
  # bindIp: 127.0.0.1
  bindIpAll: true

Answer 3

Note: Below configuration is for windows 10 & MongoDB 4.0

There are two ways to configure this.

1. Using shell commands.
2. Or through mongod.cfg.

Using shell commands

First open the cmd as administrator and go to --YourPath--\MongoDB\Server\4.0\bin

1. If you already running the MongoDB service then run this command or else, go to second point.mongod --remove

2. Then set the path for data folder, log file and ip bind using the below command

   mongod --dbpath "C:\Program Files\MongoDB\Server\4.0\data" --logpath "C:\Program Files\MongoDB\Server\4.0\log\mongod.log" --bind_ip "0.0.0.0" --install --serviceName "MongoDB"

caution: This ip configuration gives access to your DB throughout the network.

3. Now go to services.msc and find the MongoDB, then Right click -> Start the service.

Through mongod.cfg

MongoDB has a very good documentation for Configuration here.

Just change the bindIp: 127.0.0.1 to bindIp: 0.0.0.0. Then restart the service using the #3 point from the above topic.

Answer 4

success:

1. change service config file C:\Program Files\MongoDB\Server\4.0\bin\mongod.cfg

# network interfaces (wjp: comment bindIp listening on all IPs)
net:
  port: 27017
#  bindIp: 127.0.0.1
  bindIp: 0.0.0.0

2. restart mongodb service (or restart computer);
3. make sure machine level firewall open port 27017
4. connect ok.

Answer 5

No In fact, if you want to access the rest interface from any ip, you needn't set bind_ip to 0.0.0.0 in the mongod.conf, you only comment or remove the configuration item from it, as similar as

#bind_ip=127.0.0.1

And then, restart your service, you can find that you can access the rest service from the 28017 port from your machine
