Can't start MYSQL external mount centos 7

ph flag

Brand new install on a new DigitalOcean droplet. I am going to run replication into this cloud server from my local network. I was trying to install the same version etc. mysql5.6.50 and then run it on a external volume. My current db is 370gb and I will need some overhead. I created the droplet and added a 500gb drive, installed mysql started and verified proper base operation. Then I followed these instructions.

When I run systemctl start mysqld. I seem to go into a endless wait.

Running status gives:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
