Chapter 2 Before You Install Sun ONE Web Server 21

Creating a DNS Alias for the Server

If your server will run on one machine among many in a network, you or your

system administrator should set up a DNS CNAME record or an alias that points to

the actual server machine. Later, you can change the actual hostname or IP address

of the server machine without having to change all URLs that point to the server

machine.

For example, you might call the server my_server.my_company.

com and then use an

alias like

www.my_company.com. So the URLs to documents on your server would

always use the www alias instead of my_server.

UNIX and Linux User Accounts for the Server

When the Sun ONE Web Server starts, it runs with a UNIX or Linux user account

that you specify during installation. Any child processes of the server are created

with this account as the owner. It is best to create a UNIX or Linux account for the

server that has restricted access to your system resources. The account needs read

permissions for the configuration files and write permissions for the

logs

directory.

On Solaris OE, by default, a user and group account named

webservd is created for

Sun ONE Web Server if it does not already exist.

On non-Solaris UNIX platforms (where the

webservd user/group cannot be

reserved outright), if you don’t create a dedicated user account for Sun ONE Web

Server, you can use the account with the name

nobody. You might not however

want to give the user

nobody permissions for running the Sun ONE Web Server. In

addition, the user

nobody might not work on some systems if a negative uid/gid is

assigned during installation. Check the

/etc/passwd file to see if the uid for

nobody exists, and make sure it is greater than 0.

The Administration Server can also run with a user account that has write

permissions to the configuration files for all installed servers. However, it’s much

easier to run the Administration Server as

root because then the Administration

Server user can start and stop servers with port numbers less than 1024. (Port

numbers greater than 1024 can be started by any user).

The user you use to run the Sun ONE Web Server (often

nobody) should be in the

same group as the user you use to run the Administration Server (often

root).

NOTE

It’s strongly recommended that you use a dedicated account for the server.
