Replace ${WP_ROOT} with the directory location of wordpress. If you are already in the wp document root, replace with a dot .

find ${WP_ROOT} -exec chown :apache {} \;
find ${WP_ROOT} -type d -exec chmod 755 {} \;
find ${WP_ROOT} -type f -exec chmod 644 {} \;

Check the current URL, first select the database with the 'use' command (eg. use live_database;):

SELECT * FROM wp_options WHERE option_name = 'siteurl' OR option_name = 'home' ;

UPDATE wp_options SET option_value = 'http://notes.lukeslinux.co.uk' WHERE option_name = 'siteurl' OR option_name = 'home';

To prevent xmlrpc attacks add the following to a .htaccess

<Files "xmlrpc.php">
Order Allow,Deny
deny from all
</Files>

xml-rpc can use system.multicall - this can be used to execute multiple methods inside a single request. This allows applications to pass multiple commands with one http request.
This means that potential bots and hackers can use the system.multicall method to guess hundreds of passwords with a single http request

— NOTE: WordPress, Drupal and most content management systems support XML-RPC.
It can be used with Perl, Java, Python, C, C++, PHP and many other programming languages

You could also use a plugin called JetPack to assist - more information to come soon
