FreeRADIUS deployment on RedHat Enterprise Linux

OS Preparation

Installing gcc compiler tool
RHEL is not installing gcc by default, so gcc need to be installed first before configuring the source
Install gcc tools from RHEL DVD
create a folder to mount cdrom to
mkdir /cdrom
insert RHEL DVD disk 1, mount /dev/cdrom /cdrom
enter /cdrom/Packages
Install Kernal Headers first

[root@radius Packages]# rpm -Uvh kernel-headers-2.6.32-71.el6.x86_64.rpm

Looking for gcc packages
run rpm -Uvh gcc-??? (enter TAB to display all the packages that start with gcc)


[root@radius Packages]# rpm -Uvh gcc-4.4.4-13.el6.x86_64.rpm
warning: gcc-4.4.4-13.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
error: Failed dependencies:
        cloog-ppl >= 0.15 is needed by gcc-4.4.4-13.el6.x86_64
        cpp = 4.4.4-13.el6 is needed by gcc-4.4.4-13.el6.x86_64
        glibc-devel >= 2.2.90-12 is needed by gcc-4.4.4-13.el6.x86_64

If the above error displayed, enter the following command
[root@radius Packages]# rpm -Uvh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm cpp-4.4.4-13.el6.x86_64.rpm glibc-devel-2.12-1.7.el6.x86_64.rpm gcc-4.4.4-13.el6.x86_64.rpm

If this error message displayed, fix it first

error: Failed dependencies:
        libppl.so.7()(64bit) is needed by cloog-ppl-0.15.7-1.2.el6.x86_64
        libppl_c.so.2()(64bit) is needed by cloog-ppl-0.15.7-1.2.el6.x86_64

        glibc-headers = 2.12-1.7.el6 is needed by glibc-devel-2.12-1.7.el6.x86_64
Use the following link to find the package that contains libppl.so.7 and so on library http://rpmfind.net/linux/rpm2html/

[root@radius Packages]# rpm -Uvh ppl-0.10.2-11.el6.x86_64.rpm mpfr-2.4.1-6.el6.x86_64.rpm glibc-headers-2.12-1.7.el6.x86_64.rpm

Repeat the previous step.
[root@radius Packages]# rpm -Uvh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm cpp-4.4.4-13.el6.x86_64.rpm glibc-devel-2.12-1.7.el6.x86_64.rpm gcc-4.4.4-13.el6.x86_64.rpm
Install gcc-c++
[root@radius Packages]# rpm -Uvh libstdc++-devel-4.4.4-13.el6.x86_64.rpm gcc-c++-4.4.4-13.el6.x86_64.rpm

Installing libtools
[root@radius Packages]# rpm -Uvh autoconf-2.63-5.1.el6.noarch.rpm automake-1.11.1-1.2.el6.noarch.rpm libtool-2.2.6-15.5.el6.x86_64.rpm
[root@radius Packages]# rpm -Uvh libtool-ltdl-2.2.6-15.5.el6.x86_64.rpm
