PLEASE READ EACH STEP CAREFULLY!In order to log into MariaDB to secure it, well need the current
password for the root user. If youve just installed MariaDB, and
you havent set the root password yet, the password will be blank,
so you should just press enter here.Enter current password for root (enter for none):
OK, successfully used password, moving on...Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..... Success!By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.Remove anonymous users? [Y/n] y... Success!Normally, root should only be allowed to connect from localhost. This
ensures that someone cannot guess at the root password from the network.Disallow root login remotely? [Y/n] y... Success!By default, MariaDB comes with a database named test that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.Remove test database and access to it? [Y/n] y- Dropping test database...... Success!- Removing privileges on test database...... Success!Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.Reload privilege tables now? [Y/n] y... Success!Cleaning up...All done! If youve completed all of the above steps, your MariaDB
installation should now be secure.Thanks for using MariaDB! 这里针对的是知道 root 密码而需要修改的情况。 两种修改方法 1、直接在shell命令行使用 mysqladm 命令修改。 # mysqladmin -uroot -poldpassword password newpassword这种方法的弊端在于会明文显示密码。 2、登陆数据库修改密码。 # mysql -uroot -p2.1 更新 mysql 库中 user 表的字段
MariaDB [(none)] use mysql;
MariaDB [mysql] UPDATE user SET passwordpassword(newpassword) WHERE userroot;
MariaDB [mysql] flush privileges;
MariaDB [mysql] exit;2.2 或者使用 set 指令设置root密码
MariaDB [(none)] SET password for rootlocalhostpassword(newpassword);
MariaDB [(none)] exit; 如果是忘记了 root 密码则需要以跳过授权的方式启动 mariadb 来修改密码。 1、先停掉服务。 # systemctl stop mariadb 2、使用跳过授权的方式启动 mariadb。 # mysqld_safe --skip-grant-tables

MariaDB [(none)] use mysql;
MariaDB [mysql] UPDATE user SET passwordpassword(newpassword) WHERE userroot;
MariaDB [mysql] flush privileges;
MariaDB [mysql] exit; 更新密码后在跳过授权启动时也不能空密码直接登陆了。 4、关闭跳过授权启动的进程 # kill -9 1441 5、正常启动 mariadb # systemctl start mariadb 转载于:https://my.oschina.net/u/3872240/blog/3034493
