htaccess to rewrite wordpress subdirectory with permalinks to root - apache

Question

I have a wordpress site installed in the directory "wp". I want to keep it in that folder for maintenance purposes. Wordpress gives the option to create a htaccess for permalinks. You can see that code (which works) below.
What I want is a rewriterule so - to visitors - the site appears to be in the root. I've to change the rewritebase, but that didn't work.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wp/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wp/index.php [L]
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wp/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wp/index.php [L]
</IfModule>

Answer 1

1) in your dashboard, go to settings -> general and make sure
a) wordpress directory -> http://mydomain.com/wp
b) site address -> http://mydomain.com
2) move your index.php from subdirectory to the root (MOVE, don't just copy)
3) edit your index.php to read
/** Loads the WordPress Environment and Template */
require('./wp/wp-blog-header.php');
where "wp" is your subdirectory
4) delete any .htaccess file in the subdirectory
5) add this to your .htaccess in the root
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
Under this setup, your wordpress installation will be located in /wp/ directory. Visitors will visit your site using http://mydomain.com. Good luck.

Answer 2

What would you think of that :
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /wp/index.php [L]
RewriteCond %{REQUEST_URI} !^/wp/.*$
RewriteRule ^(.*)$ /wp/$1 [L]
You rewrite all non existing things to /wp/index.php, and all non /wp/ file to a /wp/ equivalent file. So if you call index.php it's in fact /wp/index.php

Answer 3

For a site with two WordPress blogs, one at the site root, and one in a subfolder, i.e. https://example.com/ and https://example.com/otherblog/, here's what i did
<Directory /data/sites/example.com/otherblog>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /otherblog/index.php [L]
</IfModule>
</Directory>
<Directory /data/sites/example.com>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
</Directory>
