问题
I've just installed MongoDB (standard Ubuntu build, not the latest stable) and for some reason I can't connect:
Mon Feb 6 03:11:22 Error: couldn't connect to server 127.0.0.1 shell/mongo.js:79
exception: connect failed
Now my machine isn't 127.x.x.1 it's for some reason x.x.x.2 (But i've changed my config to bind to that address, and also tried to bind to my public IP which provided no avail.
Config:
#mongodb.conf
# Where to store the data.
# Note: if you run mongodb as a non-root user (recommended) you may
# need to create and set permissions for this directory manually,
# e.g., if the parent directory isn't mutable by the mongodb user.
dbpath=/var/lib/mongodb
#where to log
logpath=/var/log/mongodb/mongodb.log
logappend=true
bind_ip = 199.21.114.XX
port = 27017
I've checked the logs and only startup info is displaying in there.
I've also checked that the deamon is running too, and it is - I even tried running it manually with a --fork.
Has anyone come across this before? Or any suggestions?
Thx
UPDATE:
After a restart - here are the logs:

回答1:
You must specify the IP (199.21.114.XX), by running mongo 199.21.114.XX.
Otherwise, if you want it to listen on localhost as well, you should remove the bind_ip setting in your config file.
Update Check your firewall config. Since you're connecting to the external IP, it can be configured to block, even from the local box.

I solved this problem by commenting out the following line in my /etc/mongod.conf file.
# Listen to local interface only. Comment out to listen on all interfaces.
#bind_ip = 127.0.0.1
You will need to follow this config change with restarting the mongod process.
sudo service mongod restart
回答3:
sudo rm /var/lib/mongodb/mongod.lock
回答4:
I had the same issue just because the silly mistake.
first remove mongodb file which is fine
rm -rf /tmp/mongodb-27017.sock
where I did mistake inside the /etc/mongod.conf
# network interfaces
net:
port: 27017
#bindIp: 127.0.0.1
bindIp: privateIp
instead of
net:
port: 27017
bindIp: 10.1.2.4
for listen to all available ips
bindIp: [127.0.0.1,10.128.0.2]
restart the mongodb
sudo service mongod start
hopefully this answer help for someone

By default, running the mongo console command will look for mongodb on your localhost, hence the 127.0.0.1 IP which is your local loopback. Also, the default config for mongod should be available on localhost. Its better to do it this way for now to start, unless you have turned on auth. Make sure you have auth enabled or your database is running openly on your public ip.
When you want to connect to a host other than localhost or your default config, you do:
mongo <host>
回答6:
following steps may help you :
- open terminal and run "sudo rm /var/lib/mongodb/mongod.lock"
- now run " sudo mongod --repair "
- now "sudo start mongodb"
- now just check the status of mongodb status "sudo status mongodb"
5 lastly just invoke command "mongo"
回答7:
in /etc/mongod.conf
I changed,
bindIp: 127.0.0.1
to
bindIp: 0.0.0.0
which is all ports. Yeah, I know it's risky, but I am running on an internal network.
BTW commenting out #bindIp: 127.0.0.1 did NOT work for me, running under Ubuntu 18.
回答8:
Another way is to add mongod option param bind_ip
mongod -–help
--bind_ip arg comma separated list of ip addresses to listen on - localhost by default
--bind_ip_all bind to all ip addresses
mongod --fork --logpath /var/log/mongodb.log --dbpath /data/db --bind_ip 0.0.0.0
