Starting with Red Hat Enterprise Linux (RHEL) 8 Red Hat no longer ships the “libnsl” library by default, but instead the newer “libnsl2” library.
To install and use the HELIOS services on RHEL8 the “libnsl” library has to be installed. Otherwise the following error message will be shown when running the HELIOS installer:
> installerfe: error while loading shared libraries: libnsl.so.1:
> cannot open shared object file: No such file or directory
If you have access to the Red Hat online repository with an update subscription you can use “yum” to install the missing package:
# yum install libnsl
If you don't have access to the online repositories (e.g. on an evaluation install) you can manually install the package from the RHEL installation CD/ISO:
mkdir -p /mnt/rhel8
mount -o ro /dev/cdrom /mnt/rhel8
rpm -i /mnt/rhel8/BaseOS/Packages/libnsl-2.28-42.el8.x86_64.rpm
Depending on your release media the version numbers in the file name may differ slightly.
If you plan to use the WebShare Web Server on RHEL8, you also need to install Java. The repositories offer two versions, Java 11 and Java 8. Currently only Java 8 works with WebShare. The package name is “java-1.8.0-openjdk-headless”, you may install it similar to above using “yum” or “rpm”. We are investigating the issues with Java 11 and keep this Tech Info updated.
Offering professional support and excellent technical resources is very important to us. HELIOS partners offer first level support. Our goal is that every problem and question must be resolved.
Keep the installation always up to date. Install important updates, read technical information on various topics.
HELIOS solutions are often integrated into custom solutions. Here you will find advanced technical information.
