非 www 到 www apache2 Letscrypt certbot

Question

我想將我的非 www 重定向到 www。 SSL working fine and both url working fine with ssl. https://example.com https://www.example.com both working but I want to redirect https://example.com to https://www.example. com

我在 AWS ec2 中使用 lamp-server 並為 ssl 使用 certbot。

我的 apache 配置。

<VirtualHost *:80>
    ServerName www.example.com
    ServerAlias example.com
    ServerAdmin admin@example.com
    DocumentRoot /var/www/html

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

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

    <IfModule mod_dir.c>
        DirectoryIndex index.php index.pl index.cgi index.html index.xhtml index.htm
    </IfModule>
RewriteEngine on
RewriteCond %{SERVER_NAME} =example.com [OR]
RewriteCond %{SERVER_NAME} =www.example.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

我嘗試了很多在線教程但沒有任何幫助，在此先感謝您的幫助或支持。

試試（注意：Apache 如果不去掉#開頭的注釋可能會報錯）：

# turns on the rewrite engine
RewriteEngine On
# checks if domain is not www.example.com
RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
# redirects to www.example.com
RewriteRule ^ https://www\.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
# the above is enough for 443 VirtualHost

# checks if https is not on
RewriteCond %{HTTPS} !on
# redirects to https on the same domain
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L] 

所以，你的完整配置：

<VirtualHost *:80>
    ServerName www.example.com
    ServerAlias example.com
    ServerAdmin admin@example.com
    DocumentRoot /var/www/html

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

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

    <IfModule mod_dir.c>
        DirectoryIndex index.php index.pl index.cgi index.html index.xhtml index.htm
    </IfModule>
    RewriteEngine On
    RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
    RewriteRule ^ https://www\.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
    RewriteCond %{HTTPS} !on
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</VirtualHost>

將以下內容添加到<VirtualHost *:443>配置中：

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