Create the file /lib/systemd/system/mongod.service with the following content:
[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target
[Service]
User=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongodb.conf
[Install]
WantedBy=multi-user.target
Start the service:
sudo service mongodb start
Then run the command:
mongo
You will then access the server. Hope it works for you. :)

I have recently installed Wekan on a CentOS (CentOS Linux release 7.6.1810) server and it works well. However I need to login to the MongoDB. I have followed the installation guide of MongoDB and set a password for 'admin' user. But when When the "mongo -u admin -p" command is entered it prompts for password and I get the following error. However I have another issue not starting "mongod", but it is enabled.

I created this user in mongo which does not seem to work when trying to login to the DB.
$ mongo
db.createUser(
{
user: "admin",
pwd: "abcd1234",
roles: [ { role: "root", db: "admin" } ]
}
)
Firstly I installed the latest version of mongodb and then I downgraded to to 3.2 which works with wekan. However Wekan still works fine without any issue.
This is the error I get when starting the mongod.
$ systemctl start mongod
Job for mongod.service failed because the control process exited with error code.
See "systemctl status mongod.service" and "journalctl -xe" for details.
$ systemctl enable mongod
mongod.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig mongod on
The port mongod uses is 27019 which I found from the following command.
$ ss -nutlp
tcp LISTEN 0 128 127.0.0.1:27019 *:* users:(("mongod",pid=11578,fd=6))
What am I doing wrong here?
In the output of the mongo shell connection failure:
Failed to connect to 127.0.0.1:27017, in(checking socket for error after poll), reason: errno:111 Connection refused
This tells you that it is attempting to connect to port 27017 on localhost, and that the operating system actively refused the connection because nothing is listening on that port.
The ss output shows that mongod is listening on port 27019.
Try adding --port 27019 to your mongo command line.
I'm trying to launch mongo through my script after installing mongodb, but it throw an error but when I try "mongo" from my terminal it works perfectly.
Error when I run mongo from my script :

I have been trying to install Mongodb but it keeps failing midway. When the download is complete, installation fails with a connection error:

What I've tried:
1. Changing the port:
mongo --port 4332
but it doesn't connect still:

Reinstalling the DB shows up as complete but I still can't start it. Check out the screenshot
Checking for any config files in /etc/mongo* or /var/lib/: there is none.
Note: There's no mongod service available too.
the installation seem to have worked, but the mongod was not started.
MongoDB need two element :
the "mongo" shell utility, who is used to connect to the database direcly
the "mongod" service, who is the true database programs.
to start the mongod, simply use a cmd and use the "mongod" command. this command may fail if :
the port is already used (default is 27017)
the dbpath directory was not created (default is /data/db)
Fedora repository do not install both at the same time.
the shell is in the repository under the "mongodb" name
the server is under the name "mongodb-server"
so to install both, you need to do
dnf install mongodb mongodb-server
and you can then start the mongod service with
sudo service mongod start

I have followed this steps and install MongoDB in my Linux mint and finally run this command

I found many solution but did not get it resolved. Thanks in advance.
Make sure mongod service is running locally
sudo service mongod status
and if it's not, run sudo service mongod start
If that doesn't help, try this:
sudo rm /var/lib/mongodb/mongod.lock
sudo mongod --repair
and run service mongod start again
EDIT
Try changing permissions in the mongodb folder
cd /var/lib/mongodb
sudo chown -R mongodb:mongodb *
Also, If that doesn't help, run this
sudo /usr/bin/mongod --config /etc/mongodb.conf
and tell me the output (If it works is doesn't solve your problem, the service startup still needs to be fixed, just curious)
