Non-root installations

Non-root users can install WAS Network Deployment in both silent and interactive mode for full product installations and removals, incremental feature installations, and edition upgrades. The term non-root implies an installer on an operating system such as AIX or Linux, but it also means a non-administrator group installer on a Windows system.

For existing installations, the root or non-root installer who owns the currently installed files is the only user who can perform subsequent installation or removal operations on that installation except under one of the following conditions:

The set of post-installation operations that are subject to this rule includes installing a feature, upgrading a trial or from Express to the base product, installing maintenance, and uninstalling the product.



Installation considerations

There are various considerations that examine to install as a non-root user.



Set permissions

We can use the chutils utility to change ownership to another user for the file system after installation for future operations on that product.

Certain subsequent installation operations (SIOs) on the application server can be attempted and performed by other users, whether root or non-root. SIOs include installing features, edition upgrades, and fix packs.

See Set file permissions for more information.

Restriction: The permissions features are not available on Windows operating systems.


Private GSKit installation

Installing IBM HTTP Server and the Web Server Plug-ins installs a private copy of IBM Global Security Kit (GSKit), which allows both root and non-root users to enable SSL support.

The GSKit package is installed to the gsk8 directory within the installing product's root directory.

The private copy of GSKit is maintained through GSKit update packages delivered in IBM HTTP Server and web server plug-in fix packs.

If you are using zones on the Solaris operating system, you can use the private GSKit without a zone-writable /usr directory.


Non-root limitations

There are some limitations and differences when installing as a non-root user as opposed to a root user.



Uninstallation considerations

Uninstall as an administrator: If an administrator user uninstalls an application server that is owned by another user, all registry entries for all appserver instances owned by the administrator are also be removed. You should uninstall any non-root application server with the owning non-administrator user if possible.
