This document explains how to perform a major upgrade for an existing remote agent using the installer for RHEL 8.7. To install an agent on a fresh deployment, refer to Create an agent with installer on RHEL.

Agent 2.0.0

This major upgrade to remote agents with version 2.0.0 and higher consists of five procedures:

  • Install Linux packages
  • Install OpenSSL 3.0.7
  • OpenSSL 3.0.7 environment variables configuration
  • Install Python 3.11
  • Install Python 3.11 pip

Install Linux packages

dnf install perl-core -y

Install OpenSSL 3.0.7

Each command needs to be taken and run separately.

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

Configure OpenSSL environment variables

Each command needs to be taken and run separately. 

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

Install Python 3.11

Each command needs to be taken and run separately. 

cd /usr/src
wget http://www.python.org/ftp/python/3.11.8/Python-3.11.8.tgz
tar xzf Python-3.11.8.tgz
cd Python-3.11.8
make clean
./configure --prefix=/usr/local --enable-unicode=ucs4 --with-openssl=/usr/local/ssl
make
make altinstall

Install Python 3.11 pip

Each command needs to be taken and run separately. 

wget -O get-pip-3.11.py https://bootstrap.pypa.io/get-pip.py
