Issue/Introduction

• MnR Installation issue RHEL 9.x
• Installation doesn't support RHEL 9.x systemd
• apg-services script created under /etc/systemd/system is of init.d script and not systemd script.
• Auto restart of services post server reboot will not work.
• Automated script for creating apg-services on the RHEL 9.X platform

Environment

Watch4net / MnR - 7.x versions supported on RHEL 9.x platform

Cause

MnR installation on RHEL 9.x platform still insists on /etc/init.d directory which is deprecated on RHEL systems 9.x. It does not use systemd script causing the issue w.r.t auto restart of services post server reboot.

Resolution

As a workaround, please use the attached automated script for creating apg-services on the RHEL 9.x platform, specifically to resolve issues encountered during server reboots:

1. 1. Place the attached script Binary_script_for_APG_SERVICES.sh in the /opt directory on the FrontEnd(FE)server.
   2. Change the script's permissions using: 

      chmod u+x Binary_script_for_APG_SERVICES.sh 

   3. Run the script with the -i option and enter the password for the different M&R servers when prompted: 

      ./Binary_script_for_APG_SERVICES.sh -i

   4. Run the script again to create the services on all servers: 

      ./Binary_script_for_APG_SERVICES.sh -i

Additional Information

• The script Binary_script_for_APG_SERVICES.sh must be executed only from the M&R FrontEnd server in a distributed setup. 
• The script will automatically takeall M&R server hosts from /opt/APG/Custom/WebApps-Resources/Default/centralized-management/servers.xml
• If any SSH connections fail after running the script, you need to run: 

  ./Binary_script_for_APG_SERVICES.sh -r ssh
