I recently installed a barebones CentOS 7 in a VM to set up a LAMP stack. I can connect to MySQL locally through a shell and through WB remotely, so that's all working well. SSL was a bit of pain though. I generated some self signed certs and set them up locally, and could login to MySQL with a user requiring SSL, but remotely they weren't working. Then I realised I didn't have ntpd running when I generated the certs and they probably had the wrong timestamps on them, so when I moved them to another machine and tried to use them, it got all screwy. Luckily enabling ntpd and regenerating the certs fixed it.
