Access denied for user ‘root‘@‘localhost‘ (using password: YES)

ubuntu  mysql密码不对

sudo gedit /etc/mysql/mysql.conf.d/mysqld.cnf

[mysqld]

下一行添加用来跳过密码验证

skip-grant-tables

重启mysql

/etc/init.d/mysql restart

然后终端输入mysql

mysql> use mysql;
mysql>update mysql.user set authentication_string=password('123456') where user='root';
mysql> flush privileges;
mysql> quit

此时新密码为123456

然后再去/etc/mysql/mysql.conf.d/mysqld.cnf

去掉skip-grant-tables

然后输入

mysql -u root -p
