3、安装FreeRadius
1)准备建立账户
[root@alexy ~]# groupadd -g 500 radius[root@alexy ~]# useradd -g 500 -u 500 -d /opt/radius -m -s /bin/bash radius[root@alexy ~]# passwd radiusChanging password for user radius.New UNIX password: BAD PASSWORD: it is based on a dictionary wordRetype new UNIX password: passwd: all authentication tokens updated successfully.[root@alexy ~]# tail -3 /etc/passwdgdm:x:42:42::/var/gdm:/sbin/nologinsabayon:x:86:86:Sabayon user:/home/sabayon:/sbin/nologinradius:x:500:500::/opt/radius:/bin/bash[root@alexy ~]#
2)上传软件
[root@alexy radius]# ls -lh total 4.5M-rw-r--r-- 1 root root 4.5M Aug 28 14:52 freeradius-server-3.0.9.tar.gz[root@alexy radius]# ls -lh total 4.5M-rw-r--r-- 1 root root 4.5M Aug 28 14:52 freeradius-server-3.0.9.tar.gz[root@alexy radius]# chmod 775 freeradius-server-3.0.9.tar.gz [root@alexy radius]# chown radius:radius freeradius-server-3.0.9.tar.gz [root@alexy radius]# ls -lh total 4.5M-rwxrwxr-x 1 radius radius 4.5M Aug 28 14:52 freeradius-server-3.0.9.tar.gz[root@alexy radius]#
3)解压软件
[radius@alexy ~]$ tar -xvf freeradius-server-3.0.9.tar.gz [radius@alexy ~]$ ls -lh total 4.5Mdrwxrwxr-x 13 radius radius 4.0K Jul 8 23:41 freeradius-server-3.0.9-rwxrwxr-x 1 radius radius 4.5M Aug 28 14:52 freeradius-server-3.0.9.tar.gz
4)安装软件
安装软件前先要检查如下软件是否安装,如果没有安装就用yum安装。
yum install net-snmpyum install gccyum install libtallocyum install libtalloc-devel -yyum install openssl-devel -y
5)编译安装
编译安装是最容易出现问题的地方,出现问题大部分是和FreeRADIUS所依赖的包相关。把包找到正确基本安装上没有什么问题。
用root用户安装./configuremake && make install
6)安装完成后,启动并测试
(1)启动radiusradiusd or ##启动radius:radiusd -X ##启动radius的debug模式:(2)测试radius[root@alexy ~]# radtest steve testing 127.0.0.1 1812 testing123 Sending Access-Request of id 169 to 127.0.0.1 port 1812 User-Name = "steve" User-Password = "testing" NAS-IP-Address = 127.0.0.1 NAS-Port = 1812 Message-Authenticator = 0x00000000000000000000000000000000rad_recv: Access-Reject packet from host 127.0.0.1 port 1812, id=169, length=20[root@alexy ~]# 有rad_recv代表有回复,说明radius服务器是启动起来并能正常返回消息的。
4、配置FreeRadius
FreeRadius的配置文件主要包括如下几个文件:
/usr/local/etc/raddb/radiusd.conf #radius主要配置文件/usr/local/etc/raddb/clients.conf #radius客户端配置文件/usr/local/etc/raddb/users #radius用户配置文件
5、修改配置情况
(1)radiusd.conf
# -*- text -*-#### radiusd.conf -- FreeRADIUS server configuration file.#### http://www.freeradius.org/## $Id: 81a565ed4e970318914f4c7798215a04d9ca8c15 $########################################################################## Read "man radiusd" before editing this file. See the section# titled DEBUGGING. It outlines a method where you can quickly# obtain the configuration you want, without running into# trouble.## Run the server in debugging mode, and READ the output.## $ radiusd -X## We cannot emphasize this point strongly enough. The vast# majority of problems can be solved by carefully reading the# debugging output, which includes warnings about common issues,# and suggestions for how they may be fixed.## There may be a lot of output, but look carefully for words like:# "warning", "error", "reject", or "failure". The messages there# will usually be enough to guide you to a solution.## If you are going to ask a question on the mailing list, then# explain what you are trying to do, and include the output from# debugging mode (radiusd -X). Failure to do so means that all# of the responses to your question will be people telling you# to "post the output of radiusd -X".######################################################################## The location of other config files and logfiles are declared# in this file.## Also general configuration for modules can be done in this# file, it is exported through the API to modules that ask for# it.## See "man radiusd.conf" for documentation on the format of this# file. Note that the individual configuration items are NOT# documented in that "man" page. They are only documented here,# in the comments.## As of 2.0.0, FreeRADIUS supports a simple processing language# in the "authorize", "authenticate", "accounting", etc. sections.# See "man unlang" for details.#prefix = /usr/localexec_prefix = ${prefix}sysconfdir = ${prefix}/etclocalstatedir = ${prefix}/varsbindir = ${exec_prefix}/sbinlogdir = ${localstatedir}/log/radiusraddbdir = ${sysconfdir}/raddbradacctdir = ${logdir}/radacct## name of the running server.

When# executing as root (or another user), your personal environment MAY# be set up to allow the dynamic linker to find the library. When# executing as a daemon, FreeRADIUS MAY NOT have the same# personalized configuration.## To work around the problem, find out which library contains that symbol,# and add the directory containing that library to the end of 'libdir',# with a colon separating the directory names. NO spaces are allowed.## e.g. libdir = /usr/local/lib:/opt/package/lib## You can also try setting the LD_LIBRARY_PATH environment variable# in a script which starts the server.## If that does not work, then you can re-configure and re-build the# server to NOT use shared libraries, via:## ./configure --disable-shared# make# make install#libdir = ${exec_prefix}/lib# pidfile: Where to place the PID of the RADIUS server.## The server may be signalled while it's running by using this# file.## This file is written when ONLY running in daemon mode.## e.g.: kill -HUP `cat /var/run/radiusd/radiusd.pid`#pidfile = ${run_dir}/${name}.pid# chroot: directory where the server does "chroot".## The chroot is done very early in the process of starting the server.# After the chroot has been performed it switches to the "user" listed# below (which MUST be specified). If "group" is specified, it switchs# to that group, too. Any other groups listed for the specified "user"# in "/etc/group" are also added as part of this process.## The current working directory (chdir / cd) is left *outside* of the# chroot until all of the modules have been initialized. This allows# the "raddb" directory to be left outside of the chroot. Once the# modules have been initialized, it does a "chdir" to ${logdir}. This# means that it should be impossible to break out of the chroot.## If you are worried about security issues related to this use of chdir,# then simply ensure that the "raddb" directory is inside of the chroot,# end be sure to do "cd raddb" BEFORE starting the server.## If the server is statically linked, then the only files that have# to exist in the chroot are ${run_dir} and ${logdir}. If you do the# "cd raddb" as discussed above, then the "raddb" directory has to be# inside of the chroot directory, too.##chroot = /path/to/chroot/directory# user/group: The name (or #number) of the user/group to run radiusd as.## If these are commented out, the server will run as the user/group# that started it. In order to change to a different user/group, you# MUST be root ( or have root privleges ) to start the server.## We STRONGLY recommend that you run the server with as few permissions# as possible. That is, if you're not using shadow passwords, the# user and group items below should be set to radius'.## NOTE that some kernels refuse to setgid(group) when the value of# (unsigned)group is above 60000; don't use group nobody on these systems!## On systems with shadow passwords, you might have to set 'group = shadow'# for the server to be able to read the shadow password file. If you can# authenticate users while in debug mode, but not in daemon mode, it may be# that the debugging mode server is running as a user that can read the# shadow info, and the user listed below can not.## The server will also try to use "initgroups" to read /etc/groups.# It will join all groups where "user" is a member. This can allow# for some finer-grained access controls.##user = radius#group = radius# panic_action: Command to execute if the server dies unexpectedly.## FOR PRODUCTION SYSTEMS, ACTIONS SHOULD ALWAYS EXIT.# AN INTERACTIVE ACTION MEANS THE SERVER IS NOT RESPONDING TO REQUESTS.# AN INTERACTICE ACTION MEANS THE SERVER WILL NOT RESTART.## The panic action is a command which will be executed if the server# receives a fatal, non user generated signal, i.e. SIGSEGV, SIGBUS,# SIGABRT or SIGFPE.## This can be used to start an interactive debugging session so# that information regarding the current state of the server can# be acquired.## The following string substitutions are available:# - %e The currently executing program e.g. /sbin/radiusd# - %p The PID of the currently executing program e.g. 12345## Standard ${} substitutions are also allowed.## An example panic action for opening an interactive session in GDB would be:##panic_action = "gdb %e %p"## Again, don't use that on a production system.## An example panic action for opening an automated session in GDB would be:##panic_action = "gdb -silent -x ${raddbdir}/panic.gdb %e %p > ${logdir}/gdb-%e-%p.log 2>&1"## That command can be used on a production system.## max_request_time: The maximum time (in seconds) to handle a request.## Requests which take more time than this to process may be killed, and# a REJECT message is returned.## WARNING: If you notice that requests take a long time to be handled,# then this MAY INDICATE a bug in the server, in one of the modules# used to handle a request, OR in your local configuration.## This problem is most often seen when using an SQL database. If it takes# more than a second or two to receive an answer from the SQL database,# then it probably means that you haven't indexed the database. See your# SQL server documentation for more information.## Useful range of values: 5 to 120#max_request_time = 30# cleanup_delay: The time to wait (in seconds) before cleaning up# a reply which was sent to the NAS.## The RADIUS request is normally cached internally for a short period# of time, after the reply is sent to the NAS. The reply packet may be# lost in the network, and the NAS will not see it. The NAS will then# re-send the request, and the server will respond quickly with the# cached reply.## If this value is set too low, then duplicate requests from the NAS# MAY NOT be detected, and will instead be handled as seperate requests.## If this value is set too high, then the server will cache too many# requests, and some new requests may get blocked. (See 'max_requests'.)## Useful range of values: 2 to 10#cleanup_delay = 5# max_requests: The maximum number of requests which the server keeps# track of. This should be 256 multiplied by the number of clients.# e.g. With 4 clients, this number should be 1024.## If this number is too low, then when the server becomes busy,# it will not respond to any new requests, until the 'cleanup_delay'# time has passed, and it has removed the old requests.## If this number is set too high, then the server will use a bit more# memory for no real benefit.## If you aren't sure what it should be set to, it's better to set it# too high than too low.

If you# don't have any spare threads, then the request handling will# be delayed while a new thread is created, and added to the pool.## You probably don't want too many spare threads around,# otherwise they'll be sitting there taking up resources, and# not doing anything productive.## The numbers given below should be adequate for most situations.#thread pool { # Number of servers to start initially --- should be a reasonable # ballpark figure. start_servers = 5 # Limit on the total number of servers running. # # If this limit is ever reached, clients will be LOCKED OUT, so it # should NOT BE SET TOO LOW.

To have two different instances # of a module, it first must be referred to by 'name'. # The different copies of the module are then created by # inventing two 'instance' names, e.g. 'instance1' and 'instance2' # # The instance names can then be used in later configuration # INSTEAD of the original 'name'. See the 'radutmp' configuration # for an example. # # # As of 2.0.5, most of the module configurations are in a # sub-directory. Files matching the regex /[a-zA-Z0-9_.]+/ # are loaded.

When a section like# authorize refers to a module, it's automatically loaded and# initialized. However, some modules may not be listed in any# of the following sections, so they can be listed here.## Also, listing modules here ensures that you have control over# the order in which they are initalized. If one module needs# something defined by another module, you can list them in order# here, and ensure that the configuration will be OK.#instantiate { # # Allows the execution of external scripts. # The entire command line (and output) must fit into 253 bytes. # # e.g. Framed-Pool = `%{exec:/bin/echo foo}` exec # # The expression module doesn't do authorization, # authentication, or accounting.

In 2.0, the IP address is configured via# the "ipaddr" or "ipv6addr" fields. For compatibility, the 1.x# format is still accepted.#client localhost { # Allowed values are: # dotted quad (1.2.3.4) # hostname (radius.example.com) ipaddr = 127.0.0.1 # OR, you can use an IPv6 address, but not both # at the same time.# ipv6addr = :: # any. ::1 == localhost # # A note on DNS: We STRONGLY recommend using IP addresses # rather than host names. Using host names means that the # server will do DNS lookups when it starts, making it # dependent on DNS. i.e. If anything goes wrong with DNS, # the server won't start! # # The server also looks up the IP address from DNS once, and # only once, when it starts. If the DNS record is later # updated, the server WILL NOT see that update. # # One client definition can be applied to an entire network. # e.g. 127/8 should be defined with "ipaddr = 127.0.0.0" and # "netmask = 8" # # If not specified, the default netmask is 32 (i.e. /32) # # We do NOT recommend using anything other than 32. There # are usually other, better ways to achieve the same goal. # Using netmasks of other than 32 can cause security issues. # # You can specify overlapping networks (127/8 and 127.0/16) # In that case, the smallest possible network will be used # as the "best match" for the client. # # Clients can also be defined dynamically at run time, based # on any criteria. e.g. SQL lookups, keying off of NAS-Identifier, # etc. # See raddb/sites-available/dynamic-clients for details. ## netmask = 32 # # The shared secret use to "encrypt" and "sign" packets between # the NAS and FreeRADIUS. You MUST change this secret from the # default, otherwise it's not a secret any more! # # The secret can be any string, up to 8k characters in length. # # Control codes can be entered vi octal encoding, # e.g. "\101\102" == "AB" # Quotation marks can be entered by escaping them, # e.g. "foo\"bar" # # A note on security: The security of the RADIUS protocol # depends COMPLETELY on this secret! We recommend using a # shared secret that is composed of: # # upper case letters # lower case letters # numbers # # And is at LEAST 8 characters long, preferably 16 characters in # length. The secret MUST be random, and should not be words, # phrase, or anything else that is recognizable. # # The default secret below is only for testing, and should # not be used in any real environment. # secret = testing123 # # Old-style clients do not send a Message-Authenticator # in an Access-Request.

(3)users
## Please read the documentation file ../doc/processing_users_file,# or 'man 5 users' (after installing the server) for more information.## This file contains authentication security and configuration# information for each user. Accounting requests are NOT processed# through this file. Instead, see 'acct_users', in this directory.## The first field is the user's name and can be up to# 253 characters in length. This is followed (on the same line) with# the list of authentication requirements for that user. This can# include password, comm server name, comm server port number, protocol# type (perhaps set by the "hints" file), and huntgroup name (set by# the "huntgroups" file).## If you are not sure why a particular reply is being sent by the# server, then run the server in debugging mode (radiusd -X), and# you will see which entries in this file are matched.## When an authentication request is received from the comm server,# these values are tested. Only the first match is used unless the# "Fall-Through" variable is set to "Yes".## A special user named "DEFAULT" matches on all usernames.# You can have several DEFAULT entries. All entries are processed# in the order they appear in this file. The first entry that# matches the login-request will stop processing unless you use# the Fall-Through variable.## If you use the database support to turn this file into a .db or .dbm# file, the DEFAULT entries _have_ to be at the end of this file and# you can't have multiple entries for one username.## Indented (with the tab character) lines following the first# line indicate the configuration values to be passed back to# the comm server to allow the initiation of a user session.# This can include things like the PPP configuration values# or the host to log the user onto.## You can include another `users' file with `$INCLUDE users.other'### For a list of RADIUS attributes, and links to their definitions,# see:## http://www.freeradius.org/rfc/attributes.html### Deny access for a specific user.
