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 conguration les and write

permissions for the logs directory.

On Solaris OE, by default, a user and group account named webservd is created for Sun Java

System Web Server if it does not already exist.

On non-Solaris UNIX platforms (where the webservd user/group cannot be reserved outright),

if you do not create a dedicated user account for Sun Java System 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 Java System Web Server. Sometimes the user nobody does not

work on some systems if a negative uid/gid is assigned during installation. Check the

/etc/passwd le to see if the uid for nobody exists, and make sure it is greater than 0.

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

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

conguration les for all installed servers. However, it is 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 Java System Web Server (often nobody) should be in the same

group as the user you use to run the Administration Server (often root).

Note – When changing the server user, remove any /tmp/lock.* les created in the /tmp

directory.

Windows User Accounts for the Server

You should create a Windows user account for your Sun Java System Web Server. It should

have restricted access to your system resources and run under a nonprivileged system user

account (one that has a limited set of system permissions to your system). When the server

starts, it runs with this user account. Any server extension modules the server uses are created

with this user account as the owner.

During installation, the server uses the LocalSystem account, not the user account you created.

Once you start and run the server, you should use the user account you created. You can change

the user account for the server after the installation process. You can congure that user

account so that it has permissions to get les on another computer, so that your server can serve

les that are mounted from another computer.

In addition, the user account you create for the server should belong to a group that contains

the server users for all Sun Java System servers so that multiple servers can have access to shared

les.
