[root@k8s-node1 license-v2]# mysql_secure_installation NOTE: 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 current password for the root user. If you've just installed MariaDB, and haven't set the root password yet, you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password or using the unix_socket ensures that nobody can log into the MariaDB root user without the proper authorisation. You already have your root account protected, so you can safely answer 'n'. Switch to unix_socket authentication [Y/n] y #配置认证 Enabled successfully! Reloading privilege tables.. ... Success! You already have your root account protected, so you can safely answer 'n'. Change the root password? [Y/n] y #设置root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 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 #清除匿名用户 ... 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] n #禁止root远程登录 ... skipping. 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] n #删除测试库 ... skipping. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] n #重新加载特权表 ... skipping. Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB!
