我的域轉發到 www.www.www.domain.com

在ubuntu server 16.04我有一個 wordpress 網站，我想將它與域名連結。

我在其中設置了 DNS 記錄，vutlr然後在我的伺服器中設置了虛擬主機

但是，當我輸入 www.mydomain.com 時，我會轉發到 www.www.www.mydomain.com

為什麼會這樣？

虛擬主機是：

<VirtualHost *:80>
       # The ServerName directive sets the request scheme, hostname and port that
       # the server uses to identify itself. This is used when creating
       # redirection URLs. In the context of virtual hosts, the ServerName
       # specifies what hostname must appear in the request's Host: header to
       # match this virtual host. For the default virtual host (this file) this
       # value is not decisive as it is used as a last resort host regardless.
       # However, you must set it for any further virtual host explicitly.
       #ServerName www.example.com

       ServerAdmin  myemail@email.com
       ServerName mydomain.com
       ServerAlias www.mydomain.com
       DocumentRoot /var/www/html/mysite

       # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
       # error, crit, alert, emerg.
       # It is also possible to configure the loglevel for particular
       # modules, e.g.
       #LogLevel info ssl:warn

       ErrorLog ${APACHE_LOG_DIR}/mysite-error.log
       CustomLog ${APACHE_LOG_DIR}/mysite-access.log combined

       # For most configuration files from conf-available/, which are
       # enabled or disabled at a global level, it is possible to
       # include a line for only one particular virtual host. For example the
       # following line enables the CGI configuration for this host only
       # after it has been globally disabled with "a2disconf".
       #Include conf-available/serve-cgi-bin.conf

</VirtualHost>

我的wp-config.php

wordpess的文件夾裡面還有一個htcaccess文件

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /mysite/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /mysite/index.php [L]
</IfModule>

# END WordPress

還有來自 apache2 的錯誤日誌

由於可能的配置錯誤，請求超出了 10 個內部重定向的限制。使用 ‘LimitIn$

最後是vultr中DNS記錄中的設置

我已經浪費了 3 個多小時，試圖理解為什麼一個簡單的程序（我已經做了很多次）不起作用……

但是，解決方案非常簡單……

1. 我在設置 - 正常中更改了 home 和 siteurl 以獲得域名。（感謝@Michael Hampton 的評論！）
2. 然後我簡單地清除了瀏覽器中的記憶體，一切正常
