MySQL Security Configuration Wizard mysql_secure_installation in detail

After installing ES1en-ES2en you will be prompted to run mysql_secure_installation. Running mysql_secure_installation performs several Settings:
a) sets a password for root users
b) deleted anonymous accounts
c) Cancel remote login of root user
d) removes the test library and access to the test library
