Set Apache Alias

If you want to put WordPress to sub folder you need to create file wp03.conf with following content:

Alias /wp03 "/var/www/wp03"
<Directory "/var/www/wp03">
 AllowOverride All
 Options FollowSymlinks
 Order deny,allow
 Deny from all
 Allow from all
 Require all granted
</Directory>

Now you can access your blog on http://localhost/wp03
