数据库备份:
?
#mysqldump最常用于备份一个整个的数据库: shell> mysqldump -u username -p --opt db_name > backup-file.sql #你可以这样将转储文件读回到服务器: shell> mysql -u username -p db_name < backup-file.sql
?
创建用户:
CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
??
为用户分配访问权限:
GRANT ALL ON database_name.* TO 'username'@'localhost';
?
查看用户权限:
show grants; show grants for username; show grants for username@localhost;
?
修改用户密码:
set password for username@’localhost’ = password(‘newpassword’); flush privileges;
取消用户授权:
revoke all on *.* from sss@localhost ;
?
删除用户:
use mysql delete from user where user='name' and host='localhost' ; flush privileges ;
