As one who learned Linux on the RH family systems and have used Fedora in the past, Fedora isn't long term support - shelf life only two years?
I'd consider it RH Family (Fedora) 'experimental' as evident in the version of MySQL you have ... an 'rc' is a 'release candidate'. I have moved away from Fedora because I grew tried of having to backup moodle implementation, archive that backup, wipe out the Fedora X completely and then grabbing the latest supported version of Fedora only have to repeat the entire process in 2 years. While I learned a lot, decided it best for a production Moodle to be on something long term support.
Suggest using CentOS 7 (that's based on RH Enterprise and is long term support) ... if you want to stay with RH 'family' or Ubuntu 16.04 which is also LTS.
However, should you desire to continue, investigate your RC version of MySQL for 'sql-mode' ... which, if set to ANSI, should alllow you to install 3.4 - in other words, use reserved words as column names in DB's.
If you do continue with what you have, just remember you might run into other issues and due the OS itself, since many in these forums use LTS Linuxes, answers may not be forthcoming easily. ;)
My 2 'sense', of course! ;)
