Note – It is strongly recommended that you use a dedicated account for the server.

Choosing Unique Port Numbers

You need multiple port numbers: one for the Administration Server and one for each instance

of Sun Java System Web Server. The Administration Server is a special instance of the Sun Java

System Web Server that you use to manage your Sun Java System Web Server.

The standard web server port number is 80 and the standard SSL-enabled web server port

number is 443, but you can install Sun Java System Web Server to use any port. If you use a port

other than the default port (port 80), the URL used to gain access to your home page changes.

For example, if your computer is called www.siroe.com and you choose port 9753, the URL of

your server will be http://www.siroe.com:9753/.

You should choose a random number for the Administration Server to make it harder for

anyone to breach your server. When you congure your server, you use port number of the

Administration Server. For example, for server mozilla.com, the server’s URL could be

http://www.mozilla.com:2634/.

Make sure the port you choose is not already in use. On UNIX and Linux systems, you can

check the le /etc/services on the server machine to make sure you do not assign a port

number that is reserved for another service. If you choose a port that is currently being used by

another service, the installation program prompts you for another port.

Note – If you use UNIX or Linux, and you choose a server port number lower than 1024, you

must be logged in as root to start the server. After the server binds to the port, the server

changes from the root user account to the user account you specify. If you choose a port

number higher than 1024, you do not have to be the root user to start the server.
