登录MySQL时报错
解决办法：

# /etc/init.d/mysqld stop 

# mysqld_safe --user=mysql --skip-grant-tables --skip-networking & 

# mysql -u root mysql 

mysql> UPDATE user SET Password=PASSWORD(’newpassword’) where USER=’root’; 

mysql> FLUSH PRIVILEGES; 

mysql> quit 

# /etc/init.d/mysqld restart 

# mysql -uroot -p 

Enter password: <输入新设的密码newpassword> 

mysql> 

quit后可kill progress杀死进程，重新开启终端启动MySQL
