背景 有时候我们忘记了oracle登录的用户密码,甚至是用户名称都不确定,应该怎么登陆呢 操作系统 CentOS7 Oracle12c 操作步骤 使用sqlplus登录系统:sqlplus / as sysdba,如下图 查找所有用户(需要写分号,重要!重要!重要!) select username from all_users; 修改用户密码 alter user '用户名称' identified by '新密码'; 退出即可重新登录.
修改你的my.ini或my.cnf文件,在 [mysqld] 节下加入下面一行 skip-grant-tables 然后保存并重启 MySQL 服务. /etc/init.d/mysql restart 或者 service mysql restart 下面你就可以以任何用户名密码登陆数据库了. 如果是误删了root用户,则使用下面的语句创建root用户: insert into user set Host='localhost',User='root',Password=Password('1
在cmd命令行下输入sqlplus / as sysdba alter user system identified by abc; 就可以将system用户的密码改成abc了. alter user sys identified by abc; sys用户的密码也改成abc了. 然后你再登录sqlplus:
1.停止mysql 服务 /etc/init.d/mysqld stop 2.启动mysql服务跳过授权表并在后台运行 /etc/init.d/mysqld start -u root --skip-grant-tables & 3.用root空密码登录 mysql -u root 4.修改用户名密码 use mysql update user set password=password('your password') where user='root' flush privileges
