MongoDB centos7 unable to run with a non standard port as a service

Question

I installed mongodb on a fresh centos 7
I run sudo service mongod start without any problem
When I change the port in /etc/mongod.conf and I restart the mongod service I get the following error

From /var/log/mongodb/mongod.log

I am able though to run with a different port with the following command

sudo mongod -f /etc/mongod.conf

When I run as a service user mongod runs mongodb
When I run from command line root runs mongodb

How can run the mongodb service with a different port?
By the way I succeeded on centos 6.5
Thanks

Check if this port is in use by some other application using netstat command. — vmr
I tried already, it does not work, there is nothing special about 27022, but it seems that there is something special about 27017 — ashersz
Looks like mongod has not stopped properly. You can try 'sudo mongod stop' or 'pkill mongod' and then relogin and verify. — vmr

for those people having problem like me.. my fix is allow mongodb custom port on semanage

semanage port --list | grep mongo
mongod_port_t                  tcp      27017-27019, 28017-28019

as you can see, only 27017-27019, 28017-28019 is allowed. in order to add a custom port for mongodb

semanage port -a -t mongod_port_t -p tcp 21010

you now have added the custom port

 semanage port --list | grep mongo

 mongod_port_t                  tcp      21010, 27017-27019, 28017-28019

make sure to restart mongodb
