You must complete additional steps to prepare a Red Hat® Enterprise Linux® Version 8 system for a WebSphere® Application Server installation.
About this task
After you complete the common steps that are required to install any Linux system, you must also complete extra system-specific steps that are required for Red Hat Enterprise Linux Version 8.
Verify that the prerequisite packages are installed. A Linux package registration limitation prevents the prerequisites checker program from
examining prerequisite packages on Linux systems. For more
information, see Installing and verifying Linux packages.
If Security-Enhanced Linux (SELinux) is enabled and enforced on your Red Hat Enterprise Linux Version 8
operating system while you are installing the product from the disk, mount the disk with the
following option:
-o context=system_u:object_r:textrel_shlib_t:s0
Important: If you are using Red Hat Multi Level Security (MLS), review the final s0
parameter.
Procedure
-
On all hardware platforms, install all required packages and their dependencies by running the
following yum command:
yum install gtk2 libXtst xorg-x11-fonts-Type1 psmisc libnsl
The gtk2
, libXtst
, and xorg-x11-fonts-Type1
packages are required for graphical IBM® Installation Manager and Profile Management tool support. The psmisc
package provides support for basic installation and profile
creation.
-
Install the required 32-bit packages on 64-bit x86_64 systems.
By default, this operating system installs only 64-bit runtime support. However, various applications that are included with WebSphere Application Server Version require 32-bit runtime packages, including WebSphere Customization Toolbox (WCT).
32-bit components are not supported in this operating system release on the POWER®® and S390 architectures.
-
Install the following packages and their dependencies.
dnf install glibc.i686 gtk2.i686 libXtst.i686 libXft.i686 libXtst.i686 libnsl.i686
-
On POWER systems, ensure that the kernel level is set to a minimum of 3.10.0-123.6.3.el7. Run the following command:
-
For POWER LE, review the following platform-specific
limitations:
Results
If you do not install all of the required packages, the installation does not complete correctly.
Error messages indicate missing libraries, the inability to load graphical interfaces, or other
errors that occur during the installation.
What to do next
After verifying prerequisites, verifying the product disk, and setting your installation goals,
you can start installing WebSphere Application Server by
choosing one of the following installation procedures:
