Use the main installation package to install all of the product files on the
resources in your Teracloud®
Streams domain. To reduce the product size requirement on
resources, the domain host installation package
contains only a subset of the
product files. For example, this installation package does not include the
toolkits.
If your
Teracloud®
Streams environment includes multiple resources, you must install the main installation package on at
least one resource by using one of the following installation methods:
- Interactive graphical user interface (GUI) installation
- Interactive console installation
- Silent, response-file driven installation
After you install Teracloud®
Streams on at least one resource, you can install a subset of the product files on the other
resources in your enterprise domain by using the domain host installation package.
Alternatively, you can install the main installation package on each resource in the domain, or
on a shared file system that is accessible by each resource in the domain.
Root or non-root users can install the main installation package and the domain host installation package.
If a Teracloud®
Streams installation
is shared by multiple users, you must install the product in a directory that can be
accessed by all users.
For installations that are shared by multiple users,
the preferred method is to install as the root user and specify a non-personal
administrator ID, or install by using a non-personal administrator ID such as
streamsadmin.
The main differences
between a root and non-root user installation are file ownership and
the default location of the installation files.
If you are running the installation program as a
non-root user, you are the owner of the Teracloud®
Streams
installation.
If you are running the installation program as a root
user, the program prompts you to specify the user and group that will own the
installed files. The root user cannot own the installed files.
Important: For both
root and non-root installations, the user ID and group that own the installation must
exist before running the Teracloud®
Streams
installation program.
During the installation, you are prompted to specify
the root installation directory for the installed
Teracloud®
Streams files. The
installation program appends a product version directory to the root directory. The
default installation root directory depends on your authority:
- If you have root authority, the default root directory is /opt/teracloud/streams.
- If you do not have root authority, the default root directory is home-directory/teracloud/streams.
For example, if you are installing the product with root authority and accept the
default installation directory, the product is installed in the
/opt/teracloud/streams/7.2.0.0 directory.
