You already have a process running in the port 27017 which is used by mongodb. So either you need to stop the process in that port or try with different port number.
Try mongod --port 27018
You can change the port number of your choice.
EDIT:
You can also just stop all the running instances of mongo server using
sudo killall mongod as mentioned by @Dassi Orleando in the comments.
And run mongod
