如何使 wordpress 重写规则在子目录下工作？

Question

I want to redirect certain URLs coming into a wordpress site to another directory outside the document root. It seems the simplest way to do that would be to make wordpress a subdirectory, but then how can I get its rewrite rules to redirect to this subdirectory?

These are the standard rules in the apache configuration (not .htaccess)

RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]

Since now I want to prepend wordpress to the directory, I changed it as follows

RewriteBase /wordpress/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]  

But I'm getting

[perdir /] internal redirect with /wordpress/index.php [INTERNAL REDIRECT]

instead. Why? I had initially trying prepending the "wordpress" manually throughtout the rules, but apparently %{REQUEST_FILENAME} stores the initial name and not the rewritten one.

Answer 1

I ended up doing it the way I suggested at the end of my query, not using RewriteBase at all.

RewriteRule ^index\.php$ /wordpress/index.php [L]
#this rule prepends wordpress to everything
RewriteRule "^(.*)$" /wordpress/$1

#now the files have wordpress prepended, but without directory context, these conditions compare against the whole path 
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d
# we exclude files with wordpress prepended
RewriteRule ^((?!wordpress).*)$ /wordpress/index.php [L]

I mentioned briefly that REQUEST_FILENAME wasn't working and I figured out why by upping the LogLevel to rewrite:trace6. It confirmed that REQUEST_FILENAME is getting updated by RewriteRules but without the directory context (that is, ), it was expecting a full path to the file/directory. So I fixed that by prepending %{DOCUMENT_ROOT} and now the code works.
