我有一个 Nuxt.js 程序,在 Ubuntu 操作系统的 Apache 上运行。当我将它移植到子域时,例如www.example.com,它工作正常;但当我将它移植到主域时,例如示例.com,我的程序无法运行。Ubuntu Server 和 Apache 设置示例如下:
/etc/主机名

/etc/hosts

127.0.1.1 ubuntu

100.200.300.40;
};
};
/etc/bind/named.conf.local

};

};

ServerAlias example.com

</VirtualHost>
现在的问题是,如何在主域上运行该程序并将地址重定向到www.example.com当有人去示例.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 [email protected]
ProxyPass / http://localhost:3000/
</VirtualHost>
我甚至使用了以下两个代码示例从主域重定向到子域,但仍然不起作用:
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]
答案1
example.com
这是一个从到 的简单重定向www.example.com
:
<VirtualHost www.example.com:80>
ServerName www.example.com
ServerAlias example.com
ServerAdmin [email protected]
RewriteEngine On
RewriteCond %{SERVER_NAME} example.com
RewriteRule /(.*) http://www.example/com/$1 [R]
ProxyPass / http://localhost:3000/
</VirtualHost>
答案2
我不明白为什么Nuxt.js不能在主域上运行,至少不能阿帕奇在Ubuntu操作系统。 但通过编写适当的重定向规则,我能够解决这个问题,如下所示:
<VirtualHost www.example.com:80>
ServerName www.example.com
ServerAlias example.com
ServerAdmin [email protected]
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 上运行项目,则流程如下(以下示例中的 SSL 许可证是Let's Encrypt 免费 SSL 通配符证书;有关更多信息,你可以参考这网页):
<VirtualHost www.example.com:80>
ServerName www.example.com
ServerAlias example.com
ServerAdmin [email protected]
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 [email protected]
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>
