今天在自己的机子上部署vj的时候上不去mysql数据库，通过以下两行命令轻松解决：

问题：

ttop@ttop-Lenovo:~$ mysql -u root -prootpass
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

解决：

root@ttop-Lenovo:/home/ttop# /etc/init.d/mysql stop

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service mysql stop

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) utility, e.g. stop mysql
mysql stop/waiting
root@ttop-Lenovo:/home/ttop# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
