Nuxt.js 程序未在 Ubuntu 中使用 Apache 的主域上运行

Question

我在 Ubuntu OS 中运行在 Apache 上有一个 Nuxt.js 程序。当我将它移植到像 www.example.com 这样的子域时，它工作正常；但是当我将它移植到example.com等主域时，我的程序却没有运行。 Ubuntu服务器和Apache设置示例如下：

/etc/hostname

example

/etc/hosts

127.0.0.1   localhost
127.0.1.1   ubuntu
100.200.300.40  example.com
100.200.300.40  www.example.com
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

/etc/resolv.conf

nameserver 100.200.300.40
search example.com

/etc/bind/named.conf.options

options {
    directory "/var/cache/bind";
    dnssec-validation auto;

    auth-nxdomain no;    # conform to RFC1035
    listen-on-v6 { any; };
    
    forwarders {
        100.200.300.40;
        100.200.300.40;
    };
};

/etc/bind/named.conf.local

zone "example.com" IN {
type master;
file "/etc/bind/db.example.com";
};

zone "300.200.100.in-addr.arpa" IN {
type master;
file "/etc/bind/db.100";
};

             86400 )    ; Negative Cache TTL
;
@   IN  NS  ns1.

    ServerAlias example.com
    ServerAdmin webmaster@example.com
    
    ProxyPass / http://localhost:3000/
</VirtualHost>

现在的问题是当有人访问运行主域上的程序并将地址重定向到 www.example.com =73=]example.com地址?

更新

我已经通过以下设置将我的 Node.js 程序移植到主域，但没有运行:

/etc/apache2/sites-available/example.com.conf

<VirtualHost example.com:80>
    ServerName example.com
    ServerAdmin webmaster@example.com

    ProxyPass / http://localhost:3000/
</VirtualHost>

我什至使用了以下两个代码示例从主域重定向到子域，仍然没有用：

Redirect permanent / http://www.example.com/

或

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/ [R=301,L]

Answer 1

我不明白为什么 Nuxt.js 在主域上没有运行，至少 Apache 上 Ubuntu OS. 但是通过编写适当的重定向规则，我能够解决如下问题：

<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>

如果有人想运行HTTPS上的项目，过程如下（以下示例中的SSL许可证是Let's Encrypt Free SSL Wildcard Certificate；更多信息请参考this网页）：

<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>
