2. Extract the compressed file to create the WordPress directory structure:

$ tar xzvf latest.tar.gz

3. Add a dummy .htaccess file so that this will be available for WordPress to use later.

Create the file by typing:

$ touch /tmp/wordpress/.htaccess

4. Copy over the sample configuration file to the filename that WordPress actually reads:

$ cp /tmp/wordpress/wp-config-sample.php /tmp/wordpress/wp-config.php

$ mkdir /tmp/wordpress/wp-content/upgrade

6. Copy the entire contents of the directory into our document root:

$ sudo cp -a /tmp/wordpress/. /var/www/wordpress
