In general, you should start Apache with the same user that installed the Enterprise Server. You must start Apache as root under the following circumstances:
If you are a Java Enterprise System user.
If you've used port numbers which are less than 1024.
If Apache runs as a different user from the user that starts it.
To start Apache in SSL mode, use one of the following commands:
apachectl startssl or apachectl -k start -DSSL on Apache 2.0.x. Use apachectl start on Apache 2.2.x.
If needed, check the Apache web site for the latest information on starting the Apache server.
