接下来的故事从上次开始

我记得上次安装了MariaDB，并注册了一个名为WordPress的数据库和一个名为wordpressuser的用户，准备工作已经完成了。

WordPress下载

clear~ $ cd /var/www/html

clear/var/www/html $ sudo curl -O https://wordpress.org/latest.tar.gz
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

clear/var/www/html $ sudo tar -xzvf latest.tar.gz 
パスワード: 
wordpress/
wordpress/xmlrpc.php
wordpress/wp-blog-header.php
・・・

这里还好。但之后的画面我卡住了。
无法使用上次设定的用户名访问WordPress数据库。

我在这个部分的参考是来自以下页面：https://sys-guard.com/post-18125/

clear~ $ mysql -u root -p
Enter password:

在这里突然出现了GRANT命令，但它只是为了确保”wordpressuser”这个用户不存在时才会被创建，所以不用担心。
