linux（ubuntu）Mysql ERROR 1045 (28000): Access denied for user 'root'@'localhost'解决方法

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 &

[1] 5598
