正如mysql文档中password()函数所说:
此函数在MySQL 8.0.11中被移除。
这将使mysql v8.0.11及更新版本的所有现有答案都失效。
根据mysql文档,重置root密码的新通用方法如下:
The preceding sections provide password-resetting instructions specifically for Windows and Unix and Unix-like systems. Alternatively, on any platform, you can reset the password using the mysql client (but this approach is less secure): Stop the MySQL server if necessary, then restart it with the --skip-grant-tables option. This enables anyone to connect without a password and with all privileges, and disables account-management statements such as ALTER USER and SET PASSWORD. Because this is insecure, if the server is started with the --skip-grant-tables option, it enables --skip-networking automatically to prevent remote connections. Connect to the MySQL server using the mysql client; no password is necessary because the server was started with --skip-grant-tables: shell> mysql In the mysql client, tell the server to reload the grant tables so that account-management statements work: mysql> FLUSH PRIVILEGES; Then change the 'root'@'localhost' account password. Replace the password with the password that you want to use. To change the password for a root account with a different host name part, modify the instructions to use that host name. mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass'; You should now be able to connect to the MySQL server as root using the new password. Stop the server and restart it normally (without the --skip-grant-tables and --skip-networking options).

你不需要这些。只需登录:
Mysql -u root -p
然后按照mysql>提示修改当前用户的密码:
mysql> set password=password('the_new_password');
mysql> flush privileges;
你可以尝试以下步骤来重置mysql的root密码:
首先停止Mysql服务
sudo /etc/init.d/mysql stop
以root用户登录,不需要密码 Sudo mysqld_safe—skip-grant-tables &
登录mysql终端后,你需要执行更多的命令:
use mysql;
UPDATE mysql.user SET authentication_string=PASSWORD('solutionclub3@*^G'), plugin='mysql_native_password' WHERE User='root';
flush privileges;
sudo mysqladmin -S /var/run/mysqld/mysqld.sock shutdown
重启mysql服务器后 如果你仍然面临错误,你必须访问: 重置MySQL的root密码
要更新“root”Mysql用户密码,你必须记住,你将需要超级用户权限。如果您拥有超级用户权限,请尝试执行以下命令:
MySQL 5.7.6及以上版本
sudo su
service mysql stop
mysql -u root
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
\q;
exit
mysql -u root -p MyNewPass
MySQL 5.7.5及更早版本
sudo su
service mysql stop
mysql -u root
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');
\q;
exit
mysql -u root -p MyNewPass
停止MySQL Sudo service mysql stop 制作MySQL服务目录。 Sudo mkdir /var/run/mysqld 赋予MySQL用户写入服务目录的权限。 Sudo chown mysql: /var/run/mysqld 手动启动MySQL,不需要权限检查或联网。 Sudo mysqld_safe—skip-grant-tables—skip-networking &
5.无需密码登录。 Mysql -uroot Mysql
6.更新root用户密码。
更新mysql。user SET authentication_string=PASSWORD('YOURNEWPASSWORD'), plugin='mysql_native_password' WHERE user ='root' AND Host='%'; 退出;
关闭MySQL。 sudo mysqladmin -S /var/run/mysqld/mysqld.袜子关闭 正常启动MySQL服务。 Sudo服务mysql启动
对于mysql 5.6,这个命令有效,你可以通过向导设置密码:
sudo dpkg-reconfigure mysql-server-5.6
