Radius Server Load balancing

                As of version 1.1.0, FreeRADIUS supports load balancing in module sections. Please read about configurable Fail-over for a more complete description of module sections.

                The short summary is that you can use a "load-balance" section in any place where a module name may be used. The semantics of the "load-balance" section are that one of the modules in the section will be chosen at random, evenly spread over the modules in the list.

Radius Configuration for Fail-over

• 1 Configurable Module Fail Over
• 2 Rewriting results for single modules
• 3 Fail-over configuration entries
• 4 More Complex Configurations
• 5 More Complex Configuration using "if" and "else"
• 6 Virtual Modules
• 7 Redundancy and Load-Balancing
  

Radius Server + MySql Integration

                FreeRADIUS Server works out of the box with a large list of SQL servers, but unfortunately there are a number of configuration guides available on the internet that are either for very old versions of FreeRADIUS Server, or are wrong, or both. This guide is an attempt to correct some of the misinformation.

Creating RPMs: An Overview : Building RPMs

In previous chapters, just about everything you want to do with RPMs is accomplished with the rpm command. Building RPMs is one exception. Just about everything you want to do to build an RPM is done by the rpmbuild command, often with a single command.

Warning

Older RPM manuals refer to using the –b option to the rpm command to create RPMs. Don’t use that option. Instead, always use the rpmbuild command. The reason for this change is that starting with version 4.1, RPM no longer maps the rpm -b command to the real command, rpmbuild.
