SSL works fine, how can I add in https redirection from http?

Question

Hi I'm having major problems with a server, SSL works perfectly when connecting with https://..., I need to set up redirection from http to https.

This is my ssl.conf, CentOS-6, with one IP address. SSL cert set up with SANs. Would rather not use .htaccess.

Listen 172.21.11.48:443

NameVirtualHost 172.21.11.48:443

LoadModule ssl_module   modules/mod_ssl.so
SSLEngine on
SSLSessionCache         shmcb:/var/cache/httpd/mod_ssl/ssl_scache(512000)

<VirtualHost 172.21.11.48:443>
SSLEngine on
ServerAlias      "webmail.example.com"
DocumentRoot    "/var/www/html/roundcubemail"
SSLCertificateFile /etc/pki/tls/certs/aether.example.com.crt
SSLCertificateKeyFile /etc/pki/tls/private/aether.example.com-2048.key
SSLCACertificateFile /etc/pki/tls/certs/exampleca.crt
</VirtualHost>

<VirtualHost 172.21.11.48:443>
SSLEngine on
ServerAlias      "cloud.example.com"
DocumentRoot    "/var/www/html/owncloud"
SSLCertificateFile /etc/pki/tls/certs/aether.example.com.crt
SSLCertificateKeyFile /etc/pki/tls/private/aether.example.com-2048.key
SSLCACertificateFile /etc/pki/tls/certs/exampleca.crt
</VirtualHost>

When connecting on http://webmail.example.com it errors with:

Your browser sent a request that this server could not understand. Reason: You're speaking plain HTTP to an SSL-enabled server port

When I add another vhost on port 80, Apache fails to start. Any help would be gratefully received.

You just need to edit your httpd.conf file or the file where your virtual host is specified and add these lines to redirect http to https:

  RewriteEngine On
  RewriteCond %{HTTPS} off
  RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
