This is message that hangs on the screen:
mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
It is result of command:
mysqld_safe --skip-grant-tables
What worked is to open new SSH/PuTTY session and then do command "mysql" , there im in mysql command line without entering password and i can for example change mysql root password by commands:

mysql --user=root mysql
update user set Password=PASSWORD('YourNewMysqlPassword') where user='root'; flush privileges; exit;/etc/init.d/mysqld start
