Cannot start mysqld after fresh install

[Dale Schmitz]

Hopefully I haven't started a thread here that's already in existence. I've done some looking but I can't find a topic that reflects mine.

I'm fairly new to MySQL, having used it but never installed it.

I've just installed MySQL 5.7.11 on a RHEL6 desktop system, and while the installation seems to have gone well, I can't start the server. I've looked at permissions for everything (that I can think of) and all seems well in that department. Other searches around the Internet for the same thing don't seem to apply or are significantly (enough) different.

I'm posting the results of my startup log (/var/log/mysqld.log) in the hopes someone can see something right off.

Thanks for any advice you can give:
