mysql(mariadb)忘记登陆密码,提示如下
[[email protected] ~]# mysql -uroot -p Enter password: ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: YES)
2.停止mysql
[[email protected] ~]# systemctl stop mariadb
3.使用--skip-grant-tables连接mysql,此时mysql不能进行授权操作,可重置密码
[[email protected] ~]# mysqld_safe --skip-grant-tables 161103 14:52:25 mysqld_safe Logging to ‘/var/log/mariadb/mariadb.log‘. 161103 14:52:25 mysqld_safe A mysqld process already exists
