Redirect custom domains to the Apache server

• Add a ServerAlias in the httpd-vhosts.conf file for your application. This option is designed to specify alternate names for a host and is used when matching requests. Here’s an example:

  <VirtualHost *:80>
  ServerName app.example.com
  ServerAlias www.app.example.com app.example.org www.app.example.uk.org
  ...
  
  <VirtualHost *:443>
  ServerName app.example.com
  ServerAlias www.app.example.com app.example.org www.app.example.uk.org
  

• Check that the /opt/bitnami/apache2/conf/bitnami/bitnami-apps-vhosts.conf file includes the httpd-vhosts.conf file for your application. It should include a line like the one below.

  Include "/opt/bitnami/apps/APPNAME/conf/httpd-vhosts.conf"
  

  If it does not, add the line above to the /opt/bitnami/apache2/conf/bitnami/bitnami-apps-vhosts.conf file, replacing the APPNAME placeholder with the correct directory name for your application.

NOTE: After modifying the Apache configuration files, restart Apache to apply the changes.

Redirect www.myapp.example.com to myapp.example.com

This redirection is an SEO “best practice”.

• Add the following in the httpd-vhosts.conf file for your application.

  <VirtualHost *:80>
  ServerName app.example.com
  ServerAlias www.app.example.com
  RewriteEngine On
  RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
  RewriteRule ^(.*)$ http://%1$1 [R=permanent,L]
  ...
  
  <VirtualHost *:443>
  ServerName app.example.com
  ServerAlias www.app.example.com
  RewriteEngine On
  RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
  RewriteRule ^(.*)$ https://%1$1 [R=permanent,L]
  ...
  

• Check that the /opt/bitnami/apache2/conf/bitnami/bitnami-apps-vhosts.conf file includes the httpd-vhosts.conf file for your application. It should include a line like the one below.

  Include "/opt/bitnami/apps/APPNAME/conf/httpd-vhosts.conf"
  

  If it does not, add the line above to the /opt/bitnami/apache2/conf/bitnami/bitnami-apps-vhosts.conf file, replacing the APPNAME placeholder with the correct directory name for your application.

NOTE: After modifying the Apache configuration files, restart Apache to apply the changes.

Redirect myapp.example.com to www.myapp.example.com

• Add the following in the httpd-vhosts.conf file for your application. Or, to apply this redirection by default for all applications installed, add it to the default VirtualHost in the /opt/bitnami/apache2/conf/bitnami.conf file.

  <VirtualHost *:80>
    ServerName app.example.com
    ServerAlias www.app.example.com
    RewriteEngine On
    RewriteCond %{HTTP_HOST} !^www\. [NC]
    RewriteRule ^(.*)$ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
   ...
  
  <VirtualHost *:443>
    ServerName app.example.com
    ServerAlias www.app.example.com
    RewriteEngine On
    RewriteCond %{HTTP_HOST} !^www\. [NC]
    RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
   ...
  

• If you used the httpd-vhosts.conf file for the application, check that the /opt/bitnami/apache2/conf/bitnami/bitnami-apps-vhosts.conf file includes the httpd-vhosts.conf file for your application. It should include a line like the one below.

  Include "/opt/bitnami/apps/APPNAME/conf/httpd-vhosts.conf"
  

  If it does not, add the line above to the /opt/bitnami/apache2/conf/bitnami/bitnami-apps-vhosts.conf file, replacing the APPNAME placeholder with the correct directory name for your application.
