If you are already running a previous version of Red Hat Linux on your system, you may choose to upgrade to Red Hat Linux 7.1 instead of performing a full installation. If you decide to upgrade, you must choose Upgrade instead of choosing an installation class. Follow the instructions on how to upgrade your system contained in the installation manual appropriate for your architecture. During the upgrade, you will need to make sure that the secure server packages are selected by the installation program.
When you perform an upgrade to your Red Hat Linux system, the installation program checks to see what packages are already installed. Those packages will automatically be updated to the versions included in Red Hat Linux 7.1 during the upgrade process. However, if you do not have a particular package installed, the installation program will not install the new version of that package — unless you customize your upgrade.
If you are upgrading from Red Hat Linux 7.0 or later and had the secure Web server packages installed, the upgrade process will upgrade the secure server packages. If you are upgrading from Red Hat Linux 7.0 or later, but you did not have the secure Web server packages installed, you will need to select the apache, mod_ssl and openssl packages during the package customization process. See the section called Customizing Your Upgrade to Install the Secure Server for instructions on finding the packages you will need to choose.
If you are upgrading from the US/Canada version of Red Hat Linux Professional, you will need to customize your upgrade and choose the secure server packages for installation. You may already have apache installed, but mod_ssl and openssl will not be installed, as they were not included in Red Hat Linux before Red Hat Linux 7.0. You will need to customize the upgrade to choose at least mod_ssl and openssl. See the section called Customizing Your Upgrade to Install the Secure Server for instructions on finding the packages you will need to choose.
If you are upgrading from the International version of Red Hat Linux Professional and had the apache, mod_ssl and openssl packages installed, then the installation program will select and upgrade these programs automatically.
If you are upgrading from the International version of Red Hat Linux Professional but did not have the apache, mod_ssl or openssl packages installed, then you will need to customize your upgrade and choose these packages for installation. See the section called Customizing Your Upgrade to Install the Secure Server for instructions on finding the packages you will need to choose.
If you need to customize the upgrade process, follow the upgrading instructions contained in your installation manual; basically, choose Upgrade as your Install Type and then select Customize packages to be upgraded. Then you will need to select the packages to upgrade, as described in your installation manual. To help you select packages, Table 13-1 provides the location of each secure server-related package and whether it is optional.
After you have finished, if you are also upgrading any version of Apache, see the section called Upgrading from a Previous Version of Apache. If you are not upgrading Apache, continue on to the section called An Overview of Certificates and Security.
