我有一个网站，似乎不能从非www重定向到www。
我的Apache配置如下:
RewriteEngine On
### re-direct to www
RewriteCond %{http_host} !^www.example.com [nc]
RewriteRule ^(.*)$ http://www.example.com/$1 [r=301,nc]
我错过了什么?

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>

RewriteEngine上 @ HTTP_HOST} ^yourdomain.com [NC] RewriteRule ^(.*)$ http://www.yourdomain.com/$1 [L,R=301]
检查这个完美的工作
如果你只想加载www的https版本，在apache虚拟主机文件中使用下面的配置。所有这些都可以放在一个文件中。
重定向所有HTTP到www的HTTPS:
<VirtualHost *:80>
ServerName example.com
ServerAlias www.example.com
Redirect permanent / https://www.example.com/
</VirtualHost>
重定向HTTPS非www到HTTPS www:
<VirtualHost *:443>
ServerName example.com
Redirect permanent / https://www.example.com/
</VirtualHost>
实服务器配置
<VirtualHost *:443>
ServerAdmin hostmaster@example.com
DocumentRoot "/path/to/your/sites/.htaccess-file-folder"
SetEnv APPLICATION_ENV "production"
<Directory "/path/to/your/sites/.htaccess-file-folder">
Options Indexes FollowSymLinks
DirectoryIndex index.php index.html
AllowOverride All
Order allow,deny
Allow from all
</Directory>
ServerName www.example.com
SSLEngine ON
SSLCertificateFile "/path/to/your/example.cert.pem"
SSLCertificateKeyFile "/path/to/your/example.key.pem"
ErrorLog /path/to/your/example.com-error.log
CustomLog /path/to/your/example.com-access.log combined
#Your other configurations if you have
</VirtualHost>
RewriteCond %{HTTP_HOST} ^!example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
This starts with the HTTP_HOST variable, which contains just the domain name portion of the incoming URL (example.com). Assuming the domain name does not contain a www. and matches your domain name exactly, then the RewriteRule comes into play. The pattern ^(.*)$ will match everything in the REQUEST_URI, which is the resource requested in the HTTP request (foo/blah/index.html). It stores this in a back reference, which is then used to rewrite the URL with the new domain name (one that starts with www).
[NC]表示不区分大小写的模式匹配，[R=301]表示使用代码301进行外部重定向(资源永久移动)，[L]停止所有进一步重写，并立即重定向。
这对我来说很管用:
RewriteCond %{HTTP_HOST} ^(?!www.domain.com).*$ [NC]
RewriteRule ^(.*)$ http://www.domain.com$1 [R=301,L]
在将所有域重定向到www子域时，我使用前瞻性模式(?!www.domain.com)来排除www子域，以避免Apache中的无限重定向循环。
<VirtualHost *:80>
ServerAlias example.com
RedirectMatch permanent ^/(.*) http://www.example.com/$1
</VirtualHost>
