When I attempt to start the mongodb service using the command sudo service mongod start, it doesn't work. Upon closer inspection with 'sudo service mongod status` the following is found:
● mongod.service - High-performance, schema-free document-oriented database

The configuration file has been changed to the following:
# Where and how to store data.
storage:
dbPath: /tank/mongo/mongodb
journal:
enabled: true
# where to write logging data.
systemLog:
destination: file
logAppend: true
path: /tank/mongo/log/mongodb/mongod.log
# network interfaces
net:
port: 27017
bindIp: 127.0.0.1
The mongodb user been given access to the \tank\mongodirectory using the command: sudo chown -R mongodb:users /tank/mongo.
It turns out that I was supposed to give permission to mongodb:mongodb, and not only that; the child folders didn't inherit the permissions, so I had to give the permissions at the folder levels specified in the config /tank/mongo/log/mongodb/, /tank/mongo/mongodb.
I leave the answer in case it might help someone who is in a similar situation.

I'm trying to use an external drive to store my mongo collections. As per this question, I changed dbPath in /etc/mongod.conf from /var/lib/mongodb to /media/user/drive/mongodb. I also chown'd the new path to the mongodb user.
However, when I sudo service start mongod, I cannot start the server:

When I change dbPath back to /var/lib/mongodb it starts again. How can I fix this such that I can use the path on my external drive?
Not sure which OS you run and which version of MongoDB.
On Amazon Linux 2 it's mongod user not mongodb for MongoDB-5.0
Make sure you ran chown with -R flag
-rw-r----- 1 mongod mongod 8.6M Dec 10 00:59 mongod.log
Also check logs for more hints, default location should be under
/var/log/mongodb/mongod.log
i dont know why this happening. its working normal before.
but now i cant start mongod service.
after research on google and i cant run /usr/bin/mongod --quiet --config /etc/mongod.conf by manual.
then i decide to create the .service file to run the command on background.
here's file that i write
[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target
[Service]
User=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf
[Install]
WantedBy=multi-user.target
i save it on /etc/systemd/system/mongod.service
but when i run systemctl start mongod its show me nothing output.
and i check the status with systemctl status mongod
and give me failed messages. here's detail message:

how i can fix it?
or maybe is there any way to manipulated this code /usr/bin/mongod --quiet --config /etc/mongod.conf to run on background?
I'm running ec2 instance of os Ubuntu 16.04.
I recently tried to upgrade my mongodb from 3.2 to 3.6.
And I tried to run sudo service mongod start and mongod service failed to start.
Below is the error message.

And I never edited a single line of default mongod.service file.
How can I fix this issue?
If you have just copied mongod.service file from somewhere you should edit User in [Service] section
Changing ownership of "/var/lib/mongodb" directory worked for me
Command to change ownership:
"sudo chown -R mongodb:mongodb /var/lib/mongodb"

/usr/bin/mongod - No such process. ---> This error means you have placed the mongod binary in someother path instead of the default one. Try changing the path in mongod.service file and reattempt it using service start mongodb
For me it was solved by commenting "User" and "Group" directives in the service file as described here.
I hope it helps somebody.
I have a RHEL7 server that is part of a Mongo cluster. There are three mongo processes that I would like to be automatically started on system boot. One mongod, one arbiter and one mongos:
/usr/bin/mongod -f /etc/mongo_shard001.conf
/usr/bin/mongod -f /etc/mongoarb.conf
/usr/bin/mongos -f /etc/mongos.conf
I have been trying to create systemd services for these commands i.e
[Unit]
Description=mongo configuration server
After=network.target
[Service]
User=mongod
Group=mongod
ExecStart=/usr/bin/mongod -f /etc/mongoconf.conf
[Install]
WantedBy=multi-user.target
When I try to do sudo systemctl daemon-reload && sudo systemctl start mongoconf, I get this error

I have also tried using a forked type with pid file:

But gives this error

Starting the mongo config manually works fine and creates the pid file
/usr/bin/mongod -f /etc/mongoconf.conf --pidfilepath /var/lib/mongoconf/pid --fork
The version of mongod I am using is the one from mongodb.com, and I installed it following their install guide.
db version v3.4.1
git version: 5e103c4f5583e2566a45d740225dc250baacfbd7
OpenSSL version: OpenSSL 1.0.1e-fips 11 Feb 2013
allocator: tcmalloc
modules: none
build environment:
distmod: rhel70
distarch: x86_64
target_arch: x86_64
from this repo

gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc
I am wondering if I am going about this the wrong way, is there a better way to do this?
I know you said rhel7 but since it's the only answer coming up on duckduckgo for this question, this can be useful. Under Ubuntu 15 and up:
sudo systemctl enable mongod.service
Here is my solution
make a bash script with these lines
/usr/bin/mongod -f /etc/mongo_shard001.conf
/usr/bin/mongod -f /etc/mongoarb.conf
/usr/bin/mongos -f /etc/mongos.conf
and then add this line to your crontab
#reboot root cd /foldername && ./scriptname.sh
systemd would be a better solution, if anyone knows how to set it up.
the mongo documentation is no help
I just installed mongodb by following the instructions at here.
When I try to start mongodb using command
sudo systemctl status mongodb
it goes to next command line and after that i run the command
sudo systemctl status mongodb
I got the following message

Please help me to resolve this. I have tried many things like giving permission to log and lib fies. But nothing work for me.
Thanks in advance :)
