Check whole MySql DataBase
As SuperUser:
cd /var/lib/mysql/
[verbose version - show all results]
mysqlcheck -A --debug-info -p[db.root-password]
[smart version - filters all OKs]
mysqlcheck -A --debug-info -p[db.root-password]|grep -Ev 'OK$'
!!IMPORTANT!!
1. NO SPACES ALLOWED BETWEEN '-p' AND '[db.root-password]'
2. Clean .bash_history when finished [for root passwd is here... ]
3. IF PASSOWRD IS OMITTED MYSQLCHECK WILL PROMPT FOR INLINE INPUT ***
