How can I configure MediaWiki so that I am the only one that will be able to edit content of MediaWiki?
You'll want to disable editing for non-logged in users, disable registration, and disable editing for regular users (Just in case someone is already registered)
Put this at the bottom of your LocalSettings.php
# Disable editing and account creation for regular and anonymous users $wgGroupPermissions['*']['edit'] = false; $wgGroupPermissions['*']['createaccount'] = false; $wgGroupPermissions['user']['edit'] = false; # Enable editing for yourself $wgGroupPermissions['sysop']['edit'] = true; # Hides the IP in the header $wgShowIPinHeader = false;
For more about user rights, see this manual page.
