This is the second exercise in the LPIC-1 Exam 102 course. It says "If you do not know how to do this please see the "Installing MySQL" lesson under the exam 102 course." However, I cannot find a lesson with that name. The only install to that point was using git to run a container with MariaDB. If it try and follow it with that, I get
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists!
Please help me see what I am missing.
