New package formats
Radiator 4.22 is our first release that comes with Windows MSI package and Linux packages for Red Hat Enterprise Linux 7, CentOS 7, Ubuntu 18.04 and 16.04, and Debian 9. The old package formats, tar, zip and generic RPM, are also available. Our plan is to relabel the generic RPM package to legacy RPM and depreate it in favour of distribution specific RPMs.See our earlier posts for more about new Linux and Windows packages. The topics below refer these posts for background information.
Before going to the topics below, here's what is common with each migration case. See the posts mentioned above for more details:
- Your current Radiator configuration requires no large changes
- Log directory is a prime example of packaging and startup related configuration file option that likely needs an update
- New packages automatically configure Radiator to start at system boot. You may need to remove or disable what you currently use for starting Radiator
Upgrading from old package format on Windows
Radiator MSI package comes with its own Strawberry Perl. As described in the aforementioned post, Radiator MSI package is designed to be self-contained. This also means that if you already have Radiator installed from a non-MSI package, you can switch to MSI without uninstalling your current Radiator.We recommend making a copy of your current configuration before installation and checking that old Radiator installation is disabled or removed in Windows services after MSI installation. The blog post mentioned above has a wealth of information about MSI installation and post installation tasks.
Upgrading from generic RPM on Linux
Before starting an upgrade to new el7 RPM, review the Linux post from above to see what updates your current configuration requires. Most likely log directory needs to be updated, but also note the other changes, such as, new configuration file name, and system user and group radiator that are now used to run radiusd.RPM packages for el7 replace generic RPM, which means you do not have to remove it before installing RPM for el7. We recommend making a backup of your configuration files, dictionaries and edited startup scripts and systemd service files. Although RPM package management tool renames edited files with rpmsave extension when upgrading from generic RPM, backups are recommended.
After the upgrade check that old startup scripts are disabled and Radiator is started with new systemd based unit file. It should run as radiator. See that logging and logrotate work as required.
Upgrading from tar or zip to RPM or deb
When Radiator is installed from RPM or deb package, old tar or zip based installation is not removed. Both RPM and deb packages prefer Radiator files from /opt/radiator directory, but you could consider locating old Radiator files installed from zip or tar package and removing them after the upgrade.Because zip or tar based installation does not create any system user or group, log directories or require any other settings that come with new el7 RPM and deb packages, you need to review and updated your current Radiator configuration. See the Linux packaging blog post mentioned above for the details of paths, users and other information.
Also note that you need to manually disable old startup scripts. After the upgrade check that Radiator is started with new systemd based unit file. It should run as radiator. See that logging and logrotate work as required.
