I can't start mongoDB with the command "sudo systemctl start mongod".

I'm getting the following message :

● mongod.service - MongoDB Database Server

I've already reinstalled mongodb and I having the same problem. I don't know where the error came from if you can help me. Thank you.

Solution 1

Just do those two commands for temporary solution:

sudo rm -rf /tmp/mongodb-27017.sock
sudo service mongod start

For details:

That shall be fault due to user permissions in .sock file, You may have to change the owner to monogdb user.

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock

For more details visit Documentation for installation

Solution 2

I had the same problem in Manjaro and these commands solved it:

chown -R mongodb:mongodb /var/lib/mongodb
chown mongodb:mongodb /tmp/mongodb-27017.sock

Solution 3

This worked for me and I don't reinstall MongoDB. I have created manually

sudo mkdir /var/lib/mongodb
sudo mkdir /var/log/mongodb

and changed owner for both

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown -R mongodb:mongodb /var/log/mongodb

Solution 4

These two commands solve the problem for me(Linux Mint 20.2).

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock

Solution 5

This error happend to me because of the ownship of the .sock file just try these two command

chown -R mongodb:mongodb /var/lib/mongodb
chown mongodb:mongodb /tmp/mongodb-27017.sock

now restart the mongo server-

sudo systemctl start mongod

now you can check the status of mongo server with the following command -

sudo systemctl status mongod

Solution 6

I had the same problem, so I tried changing the permissions and some other commands I found online that messed up my MongoDB installation. Following are the commands that I tried from online and screwed up my installation:

$ sudo chown mongodb:mongodb /tmp/mongodb-27017.sock

$ sudo systemctl status mongod

$ sudo systemctl start mongodb

$ sudo systemctl unmask mongodb

After that, I reinstall mongodb by using following commands, which solved the issue:

$ sudo service mongod stop

$ sudo apt-get purge mongodb-org*

$ sudo rm -r /var/log/mongodb

$ sudo rm -r /var/lib/mongodb

$ sudo apt-get install -y mongodb-org

Now start the mongodb and check the status using following commands:

$ sudo systemctl start mongod

$ sudo systemctl status mongod

Solution 7

This will worked for you and don't reinstall MongoDB.

sudo mkdir /var/lib/mongodb
sudo mkdir /var/log/mongodb

then run these commands

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown -R mongodb:mongodb /var/log/mongodb

start mongod service

sudo service mongod start 

mongod.service will be active

sudo service mongod status

Solution 8

These 3 steps solved my problem:

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown -R mongodb:mongodb /var/log/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock

Solution 9

sudo mongod --dbpath /var/lib/mongodb/ --journal
