Let’s say somehow client want the webservices to be hosted at the different port of default *:80.
Just add the following :
into /etc/httpd/conf/httpd.conf

#Listen 12.34.56.78:80
Listen 80
Listen 8080

and… if you have virtual host setting ..

just ammend as follows : 


        DocumentRoot "/opt/ZZZ/station/docroot"
        DirectoryIndex index.php index.html
        SetEnv BINLOGGERBASE /opt/ZZZ
        SetEnv ZZZBASE /opt/ZZZ
        SetEnv VERSION 1.064.cos5


        DocumentRoot "/opt/ZZZ/station/docroot"
        DirectoryIndex index.php index.html
        SetEnv BINLOGGERBASE /opt/ZZZ
        SetEnv ZZZBASE /opt/ZZZ
        SetEnv VERSION 1.064.cos5
