How to set a rewrite rule in Bitnami Wordpress

I have a bitnami apache2 wordpress site.

my htdocs is in the /opt/bitnami/apps/wordpress/htdocs directory and everything inside that has been moved to a directory called blogs which is in the same htdocs as below:

/opt/bitnami/apps/wordpress/htdocs/
                                  /blogs
                                    - contents

And now when I access blog.mydomain.com it gives the File permission error as below:

Forbidden You don't have permission to access this resource.

But when I access blog.mydomain.com/blogs I can see the content.

So, how I can redirect from blog.mydomain.com to blog.mydomain.com/blogs when someone hits blog.mydomain.com

Bitnami developer here!

If you don't plan to use the main domain as a double website setup, you could simply perform a redirection using the RedirectMatch directive in your VirtualHost.

If you use the original VirtualHost setup of the instance, add the following lines to /opt/bitnami/apache2/conf/bitnami/bitnami.conf:

...
<VirtualHost _default_:80>
+ RedirectMatch ^/$ /blog/
  DocumentRoot "/opt/bitnami/apache2/htdocs"
  <Directory "/opt/bitnami/apache2/htdocs">
  ...
</VirtualHost>
...
<VirtualHost _default_:443>
+ RedirectMatch ^/$ /blog/
  DocumentRoot "/opt/bitnami/apache2/htdocs"
  SSLEngine on
  ...
</VirtualHost>
...

Explanation: When the current URL matches the root of your domain, http(s)://YOUR-DOMAIN/, the server will redirect to the second argument of the directive, http(s)://YOUR-DOMAIN/blog

If are using another VirtualHost setup, just place this modification there.
