INTRODUCTION +--------------- + +Ignore the installation instructions in this file if you have a +pre-installed binary package. When upgrading from older versions of +FreeRADIUS, you should read ALL of this file, especially the section +on "UPGRADING" below which gives information on how to update your +configuration. + +Whether you are installing from source or a pre-built binary +package, you should read the section below "RUNNING THE SERVER". + + +2. SIMPLE INSTALLATION +---------------------- + +If you do not need to modify the default configuration, then take +the following steps to build and install the server:: + + $ ./configure + $ make + $ make install + + +3. CUSTOM INSTALLATION +---------------------- + +FreeRADIUS has autoconf support. This means you have to run +``./configure``, and then run make. To see which configuration options +are supported, run ``./configure --help``, and read it's output. The +following list is a selection from the available flags:: + + --enable-shared[=PKGS] build shared libraries [default=yes] + --enable-static[=PKGS] build static libraries [default=yes] + --with-logdir=DIR Directory for logfiles [LOCALSTATEDIR/log] + --with-radacctdir=PATH Directory for detail files [LOGDIR/radacct] + --with-raddbdir=DIR Directory for config files [SYSCONFDIR/raddb] + --with-threads Use threads, if available. (default=yes) + --with-snmp Compile in SNMP support. (default=yes) + --with-dhcp Compile in DHCP support. (default=yes) + --with-experimental-modules Use experimental and unstable modules. + (default=no) + --enable-developer Turns on super-duper-extra-compile-warnings + when using gcc, as well as experimental modules. + +The ``make install`` stage will install the binaries, the 'man' pages, +and MAY install the configuration files. If you have not installed a +RADIUS server before, then the configuration files for FreeRADIUS will +be installed. If you already have a RADIUS server installed, then + +**FreeRADIUS WILL NOT over-write your current configuration.** + +The ``make install`` process will warn you about the files it could +not install. + +If you see a warning message about files that could not be +installed, then you MUST ensure that the new server is using the new +configuration files, and not the old configuration files. The initial +output from running in debugging mode (``radiusd -X``) will tell you which +configuration files are being used. See UPGRADING above for +information about upgrading from older versions. There MAY be changes +in the dictionary files which are REQUIRED for a new version of the +software. These files will NOT be installed over your current +configuration, so you MUST verify and install any problem files by +hand, for example using ``diff(1)`` to check for changes. + +It is EXTREMELY helpful to read the output of both ``./configure``, +``make``, and ``make install``. If a particular module you expected to be +installed was not installed, then the output of the +``./configure; make; make install`` sequence will tell you why that module +was not installed. Please do NOT post questions to the FreeRADIUS +users list without first carefully reading the output of this process. + + +4. UPGRADING +------------ + +The installation process will not over-write your existing +configuration files. It will, however, warn you about the files it +did not install. + +For users upgrading from any older version to 3.0, it is *NOT* +possible to use the older configuration as-is. However, the version +2.x configuration is largely compatible, so upgrading the +configuration should not be too difficult. For details on what has +changed, see ``raddb/README.rst``. + +We STRONGLY recommend that 3.0 be installed in a different location +than any existing 1.x or 2.x installation. Any local policies can +then be migrated gradually to the new 3.0 configuration. The number +of differences in the new configuration mean that is is both simpler +and safer to migrate your configurations rather than to try and just +get the old configuration to work. + + +5. RUNNING THE SERVER +--------------------- + +If the server builds and installs, but doesn't run correctly, then +you should use debugging mode (radiusd -X) to figure out the problem. + +This is your BEST HOPE for understanding the problem. Read ALL of +the messages which are printed to the screen, the answer to your +problem will often be in a warning or error message. + +We really can't emphasize that last sentence enough. Configuring a +RADIUS server for complex local authentication isn't a trivial task. +Your ONLY method for debugging it is to read the debug messages, where +the server will tell you exactly what it's doing, and why. You should +then compare its behaviour to what you intended, and edit the +configuration files as appropriate. + +If you don't use debugging mode, and ask questions on the mailing +list, then the responses will all tell you to use debugging mode. The +server prints out a lot of information in this mode, including +suggestions for fixes to common problems. Look especially for +"WARNING" in the output, and read the related messages. + +Since the main developers of FreeRADIUS use debugging mode to track +down their configuration problems with the server, it's a good idea +for you to use it, too. If you don't, there is little hope for you to +solve ANY configuration problem related to the server. + +To start the server in debugging mode, do:: + + $ radiusd -X + +You should see a lot of text printed on the screen as it starts up. +If you don't, or if you see error messages, please read the FAQ: + + http://www.freeradius.org/faq/ + +If the server says "Ready to process requests.", then it is running +properly. From another shell (or another window), type:: + + $ radtest test test localhost 0 testing123 + +You should see the server print out more messages as it receives the +request, and responds to it. The 'radtest' program should receive the +response within a few seconds. It doesn't matter if the +authentication request is accepted or rejected, what matters is that +the server received the request, and responded to it. + +You can now edit the configuration files for your local system. You +will usually want to start with ``sites-enabled/default``. To set +which NASes (clients) can communicate with this server, +edit ``clients.conf``. +Please read the configuration files carefully, as many configuration +options are only documented in comments in the file. + +Note that is is HIGHLY recommended that you use some sort of version +control system to manage your configuration, such as git or +Subversion. You should then make small changes to the configuration, +checking in and testing as you go. When a config change causes the +server to stop working, you will be able to easily step back and find +out what update broke the configuraiton. + +Configuring and running the server MAY be complicated. Many modules +have ``man`` pages. See ``man rlm_pap``, or ``man rlm_*`` for +information. +Please read the documentation in the doc/ directory. The comments in +the configuration files also contain a lot of documentation. + +If you have any additional issues, the FAQ is also a good place to +start. + -- cgit v1.2.3
