@Adam-Poniatowski Which page is that? We can get it resolved on the docs...
Oh I meant @JaredBusch tutorial, it is just the one point that is (sort of) obsolete, but one can add that to the mongod.conf file. The nodebb docs is fine. The only thing I can suggest, is to note down, that it is assumed that selinux is either permissive or disabled. in https://nodebb.readthedocs.io/en/latest/installing/os/centos.html
And maybe add @JaredBusch semanage commands there as well
@Shard Centos 7.3, it is full systemd, hence mongod does not install/copy anything into that folder. one can still use it, but its just a drag at this point. Hacking a systemd system into a systemv... I got accustomed to the change.
