This document explains how to perform a major upgrade for an existing Remote Agent using the installer for RHEL 8.7. This procedure involves installing and configuring prerequisite packages before executing the upgrade script. For more information on how to install an agent on a new deployment, see Create an agent using installer on RHEL.

Note: To install all the packages, you must have superuser privileges. However, to ensure some dependencies remain accessible to non-root users, don't change the root user's umask from the default value of 0022.

Important: Keep the shell session open until you finish all steps.

To install and configure required packages to upgrade Remote Agents with version 2.0.0 and higher, follow these steps:

1. Run the following command to install Linux packages:

   dnf install perl-core -y

2. Run the following commands separately to install OpenSSL 3.0.7:

       cd /usr/local/src
       wget https://www.openssl.org/source/openssl-3.0.7.tar.gz
       tar -xf openssl-3.0.7.tar.gz
       cd openssl-3.0.7
       ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlib
       make -j$((`nproc`+1))
       make install

3. Run the following commands separately to configure OpenSSL environment variables:

       cd /etc/ld.so.conf.d/
       echo /usr/local/ssl/lib64 > openssl-3.0.7.conf
       ldconfig -v
       echo PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/ssl/bin" > /etc/environment
       source /etc/environment
       ln -sf  /usr/local/ssl/bin/openssl /usr/bin/openssl
       export LDFLAGS="$LDFLAGS -L/usr/local/ssl/lib64"
       export LD_LIBRARY_PATH=/usr/local/ssl/lib64
