我在做:
$ sudo vim /etc/mysql/mariadb.conf.d/50-server.cnf
然后添加
跳过授权表
然后
$ sudo service mysqld restart
然后
$ mysql -u root -p
Enter password:

然后
$ sudo vim /etc/mysql/mariadb.conf.d/50-server.cnf
然后删除
skip-grant-tables
然后
$ sudo service mysqld restart
然后
$ mysql -u root -p
Enter password:
ERROR 1698 (28000): Access denied for user 'root'@'localhost'
为什么?
如果我想
MariaDB [mysql]> SET PASSWORD FOR root = PASSWORD('sa');
ERROR 1290 (HY000): The MariaDB server is running with the --skip-grant-tables option so it cannot execute this statement
答案1
无法通过更新 mysql.user 表来管理 MySQL 凭据。
要更改用户密码,请运行以下脚本:
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
