I am trying to do a Mod_Rewrite and get rid of all www. in the url. All my SSL certificates are non-www and I don't want to create SSL certs for www. subdomains. I just want to rewrite and redirect.
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
RewriteEngine on
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI}
RewriteCond %{HTTP_HOST} ^www\.(.+) [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [END,L,R=permanent]
</VirtualHost>
<Directory /var/www>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
Followed by sudo systemctl restart apache2 but with testing, the www. is still persistent.
<VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www/html ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined RewriteEngine on RewriteCond %{HTTPS} off RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} RewriteCond %{HTTP_HOST} ^www\.(.+) [NC] RewriteRule ^ https://%1%{REQUEST_URI} [END,L,R=permanent] </VirtualHost>
The rule you've posted is in the <VirtualHost *:80> container so it only applies to HTTP (non-HTTPS) traffic. However, it will never be processed anyway since you are redirecting to HTTPS on the "same host" in the immediately preceding rule. You need to reverse these two rules if you wish to prioritise the removal of the www subdomain (when accessing over HTTP). (Oridinarily, this would only need to be done in the <VirtualHost *:443> (HTTPS) container.)
(However, if you wish to implement HSTS then the rules are already in the correct order. Although you are missing the flags argument from the first rule.)
However, you are also missing the ServerName and ServerAlias directives from this vHost container so it's unclear whether the www subdomain would even resolve here (or what domain resolves here for that matter).
For example:
ServerName example.com
ServerAlias www.example.com
:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.(.+) [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [R=permanent,L]
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
However, if you wish to redirect HTTPS traffic from www to non-www then you have no choice but to make sure the SSL cert covers the www subdomain as well (otherwise the request won't even reach your server). And the relevant rule to remove www would need to be repeated in the <VirtualHost *:443> (HTTPS) container.
