Apache-2.4
Nuxt.js 程序未在 Ubuntu 中使用 Apache 在主域上執行
我有一個 Nuxt.js 程序，我在 Ubuntu 作業系統的 Apache 上執行。當我將它移植到像**www.example.com這樣的子域時，它工作正常；但是當我將它移植到example.com**等主域時，我的程序無法執行。Ubuntu Server 和 Apache 設置範例如下：
/etc/主機名
example/etc/hosts

<VirtualHost www.example.com:80> ServerName www.example.com ServerAlias example.com ServerAdmin webmaster@example.com ProxyPass / http://localhost:3000/ </VirtualHost>現在的問題是，當有人訪問example.com地址時，如何在主域上執行程序並將地址重定向到例如**www.example.com**？
更新
我已經通過以下設置將我的 Node.js 程序移植到主域，但沒有執行：
/etc/apache2/sites-available/example.com.conf
<VirtualHost example.com:80> ServerName example.com ServerAdmin webmaster@example.com ProxyPass / http://localhost:3000/ </VirtualHost>而且我什至使用了以下兩個程式碼範例從主域重定向到子域，仍然不起作用：
Redirect permanent / http://www.example.com/或者
RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
我不明白為什麼Nuxt.js不能在主域上執行，至少在Ubuntu作業系統上使用Apache 。 但是通過編寫適當的Redirect Rule，我能夠解決這個問題，如下所示：
<VirtualHost www.example.com:80> ServerName www.example.com ServerAlias example.com ServerAdmin webmaster@example.com ProxyPass / http://localhost:3000/ RewriteEngine on RewriteCond %{REQUEST_SCHEME}://%{SERVER_NAME} =http://example.com [OR] RewriteCond %{REQUEST_SCHEME}://%{SERVER_NAME} =http://www.example.com RewriteRule ^ http://www.example.com%{REQUEST_URI} [END,NE,R=permanent] </VirtualHost>如果有人想在 HTTPS 上執行項目，過程如下（以下範例中的 SSL 許可證是Let’s Encrypt Free SSL Wildcard Certificate；有關它的更多資訊，您可以參考此網頁）：
<VirtualHost www.example.com:80> ServerName www.example.com ServerAlias example.com ServerAdmin webmaster@example.com ProxyPass / http://localhost:3000/ RewriteEngine on RewriteCond %{REQUEST_SCHEME}://%{SERVER_NAME} =http://example.com [OR] RewriteCond %{REQUEST_SCHEME}://%{SERVER_NAME} =http://www.example.com RewriteRule ^ https://www.example.com%{REQUEST_URI} [END,NE,R=permanent] </VirtualHost> <IfModule mod_ssl.c> <VirtualHost www.example.com:443> ServerName www.example.com ServerAlias example.com ServerAdmin webmaster@example.com ProxyPass / http://localhost:3000/ RewriteEngine on RewriteCond %{REQUEST_SCHEME}://%{SERVER_NAME} =https://example.com RewriteRule ^ https://www.example.com%{REQUEST_URI} [END,NE,R=permanent] Include /etc/letsencrypt/options-ssl-apache.conf SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem </VirtualHost> </IfModule>
example.com這是一個從to的簡單重定向www.example.com：<VirtualHost www.example.com:80> ServerName www.example.com ServerAlias example.com ServerAdmin webmaster@example.com RewriteEngine On RewriteCond %{SERVER_NAME} example.com RewriteRule /(.*) http://www.example/com/$1 [R] ProxyPass / http://localhost:3000/ </VirtualHost>
