我已经安装了apache virtualhosts并确认其工作正常。我想为其中一个vhost安装wordpress，所以我解压缩了该vhost文档根目录中的所有wordpress文件。我继续按照WordPress安装说明进行操作。现在，我在转到安装时遇到数据库连接错误。php。我从phpMyAdmin创建了DB和WordPress用户。这是我的wp配置。php：
<?php

所以我是MySql新手，但我尽可能多地排除了故障。我使用SET为我的Wordpress DB用户创建了一个新密码。还是没有骰子。我确认mysql正在运行。我仔细检查了密码和拼写。我试图使用Wordpress DB用户登录mysql，但我得到了：
ERROR 1045 (28000): Access denied for user \'l********e\'@\'localhost\' (using password: YES)
我想这可能是因为我的Wordpress DB用户没有全局权限，但我真的不知道，因为今天基本上是我使用mysql的第一天。
我唯一能想到的是，由于apache vhosts的原因，“localhost”不是正确的DB主机名，但每个人都说它仍然应该是正确的。哦，值得注意的是，在phpMyAdmin中，我的Wordpress用户在用户概述中的“主机”是“%”，直到我将其更改为“localhost”（在更改之前，我尝试将wp-config.php DB host设置为“%”。
还尝试在我的所有网站所在的/var/www/*中打开权限，但没有帮助。chown到www数据也没什么
更新我通过重新开始并通过命令行执行所有操作来修复它。但现在我想知道为什么会这样。
