这是我自己网站的配置，工作起来很有魅力。

<IfModule mod_ssl.c>
  <VirtualHost *:443>
    ServerAdmin admin@domain.com

    ServerName www.domain.com
    ServerAlias domain.com

    DocumentRoot /var/www/html/domain

    <Directory /var/www/html/domain/>
      Options FollowSymLinks
      AllowOverride All
      Require all granted
    </Directory>

    # Redirect non-www to www
    RewriteEngine On

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

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

    Include /etc/letsencrypt/options-ssl-apache.conf
    SSLCertificateFile /etc/letsencrypt/live/domain.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/domain.com/privkey.pem
  </VirtualHost>
</IfModule>

<VirtualHost *:80>
    ServerAlias example.com
    RedirectMatch permanent ^/(.*) http://www.example.com/$1
</VirtualHost>

这将重定向不仅域名，而且内部 pages.like…… example.com/abcd.html               ==>    www.example.com/abcd.html example.com/ab/cd.html ? ef = gh   ==>     www.example.com/ab/cd.html ? ef = gh

如果你只想加载www的https版本，在apache虚拟主机文件中使用下面的配置。所有这些都可以放在一个文件中。

重定向所有HTTP到www的HTTPS:

<VirtualHost *:80>
    ServerName example.com
    ServerAlias www.example.com
    Redirect permanent / https://www.example.com/
</VirtualHost>

重定向HTTPS非www到HTTPS www:

<VirtualHost *:443>
    ServerName example.com
    Redirect permanent / https://www.example.com/
</VirtualHost>

实服务器配置

<VirtualHost *:443>
    ServerAdmin hostmaster@example.com
    DocumentRoot "/path/to/your/sites/.htaccess-file-folder"
    SetEnv APPLICATION_ENV "production"

    <Directory "/path/to/your/sites/.htaccess-file-folder">
            Options Indexes FollowSymLinks
            DirectoryIndex index.php index.html
            AllowOverride All
            Order allow,deny
            Allow from all
    </Directory>
    ServerName www.example.com
    
    SSLEngine ON
    SSLCertificateFile "/path/to/your/example.cert.pem"
    SSLCertificateKeyFile "/path/to/your/example.key.pem"

    ErrorLog /path/to/your/example.com-error.log
    CustomLog /path/to/your/example.com-access.log combined
    #Your other configurations if you have
</VirtualHost>

    <VirtualHost *:80>
       DocumentRoot "what/ever/root/to/source"
       ServerName www.example.com

       <Directory "what/ever/root/to/source">
         Options FollowSymLinks MultiViews Includes ExecCGI
         AllowOverride All
         Order allow,deny
         allow from all
         <What Ever Rules You Need.>
      </Directory>

    </VirtualHost>

    <VirtualHost *:80>
      ServerName example.com
      ServerAlias *.example.com
      Redirect permanent / http://www.example.com/
    </VirtualHost>

这就是上面代码所发生的情况。第一个虚拟主机块检查请求是否为www.example.com，并在该目录下运行您的网站。

如果做不到这一点，就进入第二个虚拟主机部分。在这里，除www.example.com之外的任何内容都被重定向到www.example.com。

这里的顺序很重要。如果你先添加第二个virtualhost指令，它将导致一个重定向循环。

此解决方案将重定向到您的域www.yourdomain.com的任何请求。

干杯!

如果你有多个域名(可选)

-如果所有这些域名都使用https(因为他们应该)

-如果你想让所有的域名都使用www。domainName

这将避免doble重定向(http://non www到http://www，然后到https://www)

<VirtualHost *:80>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^(.*)$ https://www.%1$1 [R=301,L]
</VirtualHost>

And

<VirtualHost *:443>
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}$1 [R=301,L]
</VirtualHost>

您应该将重定向代码301更改为最方便的代码

重定向代码的非www => www和相反的www =>非www。在.htaccess文件中没有硬编码域和方案。因此，源域名和http/https版本将被保留。

Apache 2.4及更新版本

www => www:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ %{REQUEST_SCHEME}://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

WWW =>非WWW:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ %{REQUEST_SCHEME}://%1%{REQUEST_URI} [R=301,L]

注意:在Apache 2.2上无效，%{REQUEST_SCHEME}不可用。为了与Apache 2.2兼容，请使用下面的代码或将%{REQUEST_SCHEME}替换为固定的http/https。

Apache 2.2及更新版本

www => www:

RewriteEngine On

RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

．.． 或者更短的版本……

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTPS}s ^on(s)|offs
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

WWW =>非WWW:

RewriteEngine On

RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]

RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L]

．.． 更短的版本不可能，因为%N仅可从上次RewriteCond…
