This is a problem that requires you to force the password to be modified in the following ways:

/etc/init.d/mysql Stop (service mysqld stop)
/usr/bin/mysqld_safe--skip-grant-tables
Open an SSH connection in addition
[Root@localhost ~]# MySQL
Mysql>use MySQL
Mysql>update User Set Password=password ("123456") where user= "root";
Mysql>flush privileges;
Mysql>exit

Pkill-kill-t pts/0 can force a * * User with pts 0 (previously running the Mysqld_safe User window) to kick out
Normal start Mysql:/etc/init.d/mysql start (Service mysqld start)
