Mongodb /var/log/mongodb/mongod.log prevents mongod from starting

Question

I am using mongodb 3.6.3 on a centos 7 aws ec2 instance.

2 Questions (only one needs to be answered):

1. Why is the --logpath preventing the mongod command if done manually through the cli with sudo mongod --storageEngine etc
2. Why is sudo service mongod status showing the failure that it is?

When I run the below command, (since currently, sudo service mongod start isn't working but the below works) it fails when I specify the --logpath but will run without it. Unfortunately, when I run it without it, all of my logs end up in the / which is absolutely the wrong location.

sudo mongod --storageEngine wiredTiger --dbpath /data --bind_ip 127.0.0.1,apiIP --logpath /var/log/mongodb/mongod.log --auth --fork

Below is what happens when I try to run that above line as is.

I CONTROL [main] log file "/var/log/mongodb/mongod.log" exists; moved to "/var/log/mongodb/mongod.log.2018-03-16T15-16-01".

From what I can tell, it is conflicting with the currently existent

Just for reference, sudo service mongod status returns:

Thanks to @AlexBlex for noticing the spacing issue in the yaml file.

With that sorted, the status error has this line Unrecognized option: storage.wiredTiger

Answer 1

1. cd /var/log
2. sudo mkdir -m 777 mongodb
3. sudo service mongod start
4. sudo service mongod status

Hopefully, that's will do!
