MariaDB服务器软件包自带一个名为mysql_secure_installation的 脚本，可以轻松提高数据库服务器的安全性。

wuxiangping@linuxcool:~$ sudo mysql_secure_installationNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!In order to log into MariaDB to secure it, we'll need the currentpassword for the root user.  If you've just installed MariaDB, andyou haven't 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):     直接回车OK, successfully used password, moving on...Setting the root password ensures that nobody can log into the MariaDBroot user without the proper authorisation.You already have a root password set, so you can safely answer 'n'.Change the root password? [Y/n] y    设置root用户密码New password: Re-enter new password: Password updated successfully!Reloading privilege tables.. ... Success!By default, a MariaDB installation has an anonymous user, allowing anyoneto log into MariaDB without having to have a user account created forthem.

[Y/n] y  禁止root原创连接 ... Success!By default, MariaDB comes with a database named 'test' that anyone canaccess.  This is also intended only for testing, and should be removedbefore moving into a production environment.Remove test database and access to it? [Y/n] y   删除默认的test数据库名 - Dropping test database... ... Success! - Removing privileges on test database... ... Success!Reloading the privilege tables will ensure that all changes made so farwill take effect immediately.Reload privilege tables now? [Y/n] y   刷新立即生效 ... Success!Cleaning up...All done!  If you've completed all of the above steps, your MariaDBinstallation should now be secure.Thanks for using MariaDB!

本地root用户登录

shell与MariaDB交互操作，运行时会提示输入系统用户名的密码

wuxiangping@linuxcool:~$ sudo mysql[sudo] wuxiangping 的密码： Welcome to the MariaDB monitor.

授权MariaDB指定主机远程访问

默认监听端口是127.0.0.1，需要修改为主机IP

wuxiangping@linuxcool:~$ sudo vim /etc/mysql/mariadb.conf.d/50-server.cnfbind-address=127.0.0.1修改为bind-address=192.168.3.22
