The installation is the beginning of the work. It is very important to install OpenSER correctly from the source code. You can install much faster from the Debian packages or using the apt-get utility. However, the installation from the source code is much more flexible allowing you to select which modules will be compiled. You cannot install RADIUS accounting support from the Debian Packages. That's why we won't use any shortcut to the installation. I strongly advise you to install using Debian.
If you choose to install on another platform, you will have to deal with init scripts and fixing the installation of the other packages.
By the end of this chapter you will be able to:
Install Linux prepared for OpenSER
Download OpenSER source and its dependencies
Compile and install OpenSER with MySQL and RADIUS support
Start and stop OpenSER
Configure the Linux system to start OpenSER at boot time.
