Oct 27 19:38:45 webserver apachectl[9629]: apache2: Syntax error on
line 225 of /etc/apache2/apache2.conf: Sy

This is the error that's preventing Apache from running, on "line 225
of /etc/apache2/apache2.conf", it looks as if you have truncated the
full error message (unless that was me).

Anyway, show us that line (and a few lines aroun d it for context) and
I'm sure someone will be able to tell you what's wrong.

There may be more/better information about the apache configuration
error in the apache error log at /var/log/apache/error.log.
