Oops, something went wrong… [404]

I tried to reinstall couple of times from other providers unfortunately result is the same.

When I check systemctl status mysqld or MySQL service not found.

However when I try yum install MySQL it shows its already installed .

installogx as above, I was able to install everyday until 2.1.2 release…

I have same issues : We are not able to run systemctl start mysql return code: 5. Fatal error,
