Issue/Introduction

The Web Agent configuration wizard is unable to detect the IHS HTTP server install, despite the correct path specified and httpd.conf verified.

 

Cause

The Web Agent configuration wizard uses the command 'httpd -v' to determine the Web Server version.

If the configuration wizard is unable to execute this command, it cannot work properly.

The default ASF Apache that is installed on Redhat works out of the box as it has the path to the binaries are already present in the system environment variables.

However, because the IBM IHS HTTP server is a new installation of 3rd party software in a custom location, the path to the binaries needs to be explicitly sourced.

Without doing this, the 'httpd -v' will fail, and the Web Agent configuration wizard will be unable to determine the correct Web Server version.

 

Resolution

Example IBM IHS HTTP server install path: /opt/IBM/HTTPServer/

Verify current environment variables:

# env

Configure system environment variable to contain the IBM IHS HTTP server library path:

# export LD_LIBRARY_PATH=/opt/IBM/HTTPServer/lib:$LD_LIBRARY_PATH

Verify environment variables again for new path:

# env

Rerun Web Agent configuration wizard and confirm IBM IHS HTTP server is detected correctly:

Consider also sourcing the LD_LIBRARY_PATH globally by using the /etc/profile or /etc/profile.d scripts.

Consult with your RedHat Administrator for more information.
