（一）簡介
freeradius通常用來進行帳戶認證管理，記帳管理，常見的電信運營商的寬帶帳戶，上網帳戶管理，記帳，都是使用的radius服務器進行鑑權記帳的。Freeradius包含一個radius服務器和radius-client，能夠對支持radius協議的網絡設備進行鑑權記帳。 ------百度百科vim

（二）安裝配置服務服務器

[root@localhost ~]# yum install freeradius freeradius-ldap freeradius-utils -y
[root@localhost ~]# systemctl enable radiusd.service
[root@localhost ~]# systemctl start radiusd.service

（三）修改相關配置文件網絡

3.1，修改/etc/raddb/mods-available/ldap文件，主要是ldap部分，其餘的都是默認ide

[root@localhost raddb]#  cat /etc/raddb/mods-available/ldap | grep -v '#' | grep -v ^$
ldap {
server = 'x.x.x.x'   #服務器
port = 389   #端口
identity = 'CN=opsldap,CN=Users,DC=txxxdxx,DC=me'  #鏈接LDAP賬號
password =xxxxxxxx   #鏈接LDAP密碼
base_dn = 'DC=txxxdxx,DC=me'   #dn
sasl {
}
update {
control:Password-With-Header    += 'userPassword'
control:                        += 'radiusControlAttribute'
request:                        += 'radiusRequestAttribute'
reply:                          += 'radiusReplyAttribute'
}
edir = no   #修改
user {
base_dn = "${..base_dn}"
filter = "(sAMAccountName=%{%{Stripped-User-Name}:-%{User-Name}})"     #修改爲sAM
如下用默認
sasl {
}
}
group {
base_dn = "${..base_dn}"
filter = '(objectClass=posixGroup)'
membership_attribute = 'memberOf'
}
profile {
}
client {
base_dn = "${..base_dn}"
filter = '(objectClass=radiusClient)'
template {
}
attribute {
ipaddr                          = 'radiusClientIdentifier'
secret                          = 'radiusClientSecret'
}
}
accounting {
reference = "%{tolower:type.%{Acct-Status-Type}}"
type {
start {
update {
description := "Online at %S"
}
}
interim-update {
update {
description := "Last seen at %S"
}
}
stop {
update {
description := "Offline at %S"
}
}
}
}
post-auth {
update {
description := "Authenticated at %S"
}
}
options {
chase_referrals = yes
rebind = yes
res_timeout = 10
srv_timelimit = 3
net_timeout = 1
idle = 60
probes = 3
interval = 3
ldap_debug = 0x0028
}
tls {
}
pool {
start = ${thread[pool].start_servers}
min = ${thread[pool].min_spare_servers}
max = ${thread[pool].max_servers}
spare = ${thread[pool].max_spare_servers}
uses = 0
retry_delay = 30
lifetime = 0
idle_timeout = 60
}

3.2，建立軟鏈接在mods-enable/模塊下post

[root@localhost raddb]# ln -s /etc/raddb/mods-available/ldap /etc/raddb/mods-enabled/
[root@localhost raddb]# ll /etc/raddb/mods-enabled/ldap 
lrwxrwxrwx 1 root root 30 Jul 17 18:19 /etc/raddb/mods-enabled/ldap -> /etc/raddb/mods-available/ldap

3.3，在site-avaiable/下建立site_ldap文件測試

[root@localhost raddb]# cat /etc/raddb/sites-available/site_ldap 

ldap {
        server = 'x.x.8.55'   #服務器
        port = 389   #端口
        identity = 'CN=opsldap,CN=Users,DC=txxxdxx,DC=me'  #鏈接LDAP賬號
        password =xxxxxxxx   #鏈接LDAP密碼
        base_dn = 'DC=txxxdxx,DC=me'   #dn
        sasl {
        }
        update {
                control:Password-With-Header    += 'userPassword'
                control:                        += 'radiusControlAttribute'
                request:                        += 'radiusRequestAttribute'
                reply:                          += 'radiusReplyAttribute'
        }
        edir = no   #修改
        user {
                base_dn = "${..base_dn}"
                filter = "(sAMAccountName=%{%{Stripped-User-Name}:-%{User-Name}})"     #修改爲sAM
#如下用默認
                sasl {
                }
        }
        group {
                base_dn = "${..base_dn}"
                filter = '(objectClass=posixGroup)'
                membership_attribute = 'memberOf'
        }
        profile {
        }
        client {
                base_dn = "${..base_dn}"
                filter = '(objectClass=radiusClient)'
                template {
                }
                attribute {
                        ipaddr                          = 'radiusClientIdentifier'
                        secret                          = 'radiusClientSecret'
                }
        }
        accounting {
                reference = "%{tolower:type.%{Acct-Status-Type}}"
                type {
                        start {
                                update {
                                        description := "Online at %S"
                                }
                        }
                        interim-update {
                                update {
                                        description := "Last seen at %S"
                                }
                        }
                        stop {
                                update {
                                        description := "Offline at %S"
                                }
                        }
                }
        }
        post-auth {
                update {
                        description := "Authenticated at %S"
                }
        }
        options {
                chase_referrals = yes
                rebind = yes
                res_timeout = 10
                srv_timelimit = 3
                net_timeout = 1
                idle = 60
                probes = 3
                interval = 3
                ldap_debug = 0x0028
        }
        tls {
        }
        pool {
                start = ${thread[pool].start_servers}
                min = ${thread[pool].min_spare_servers}
                max = ${thread[pool].max_servers}
                spare = ${thread[pool].max_spare_servers}
                uses = 0
                retry_delay = 30
                lifetime = 0
                idle_timeout = 60
        }
}

3.4，在site-enabled下建立軟鏈接ui

[root@localhost raddb]# ln -s /etc/raddb/sites-available/site_ldap /etc/raddb/sites-enabled/
[root@localhost raddb]# ll /etc/raddb/sites-enabled/site_ldap 
lrwxrwxrwx 1 root root 36 Jul 17 18:21 /etc/raddb/sites-enabled/site_ldap -> /etc/raddb/sites-available/site_ldap

（四），隊radius進行相關的測試，能夠經過重啓服務器或者radiusd -X 進行測試設置spa

[root@localhost mods-available]# systemctl restart radiusd
或者
[root@localhost mods-available]# radiusd  -X

4.1,修改 /etc/raddb/clients.conf 文件，客戶端認證的網段和密鑰。（修改服務器端記錄客戶端的配置文件 /etc/raddb/clients.conf 文件，該文件默認值提供了本機測試的 local 配置，即：安裝完後默認只容許本機的client客戶端訪問radius服務器）debug

[root@localhost raddb]#  cat /etc/raddb/clients.conf | grep -v '#' | grep -v ^$
client localhost {        ###認證的網段
    ipaddr = 127.0.0.1   ###被認證能夠訪問的ip地址
    proto = *
    secret = testing123      ###密鑰
    require_message_authenticator = no
    limit {
        max_connections = 16
        lifetime = 0
        idle_timeout = 30
    }
}
client localhost_ipv6 {
    ipv6addr    = ::1
    secret      = testing123
}

4.2，修改測試用戶文件/etc/raddb/users，添加測試帳號bob，密鑰：hellorest

[root@localhost raddb]#  cat /etc/raddb/users | grep -v '#' | grep -v ^$
bob Cleartext-Password := "hello"
Reply-Message := "Hello, %{User-Name}"
DEFAULT Framed-Protocol == PPP
Framed-Protocol = PPP,
Framed-Compression = Van-Jacobson-TCP-IP
DEFAULT Hint == "CSLIP"
Framed-Protocol = SLIP,
Framed-Compression = Van-Jacobson-TCP-IP
DEFAULT Hint == "SLIP"
Framed-Protocol = SLIP

4.3，測試是否正常

[root@localhost raddb]# radtest bob hello localhost 0 testing123
Sent Access-Request Id 151 from 0.0.0.0:52757 to 127.0.0.1:1812 length 73
    User-Name = "bob"
    User-Password = "hello"
    NAS-IP-Address = 127.0.0.1
    NAS-Port = 0
    Message-Authenticator = 0x00
    Cleartext-Password = "hello"
  Received Access-Accept Id 151 from 127.0.0.1:1812 to 0.0.0.0:0 length 32
    Reply-Message = "Hello, bob"

（五）Freeradius添加其餘網段的測試
1，服務器端配置：修改vim /etc/raddb/clients.conf 文件，增長一個client並配置共享密鑰 secret = tdops,shortname能夠任意。clientIP能夠是一個地址也能夠是一個網段。
，添加以下格式的認證

[root@localhost raddb]# vim /etc/raddb/clients.conf 
client 172.20.66.0/24 {
        secret = testing123
        showtanme = CE-SW
        }

2，在規定網段的主機作測試。

[root@localhost ~]#  radtest lqb xxx 172.20.66.127:1833 0 testing123
Sent Access-Request Id 186 from 0.0.0.0:39032 to 172.20.66.127:1833 length 80
    User-Name = "lqb"
    User-Password = "xxx"
    NAS-IP-Address = 127.0.0.1
    NAS-Port = 0
    Message-Authenticator = 0x00
    Cleartext-Password = "xxx"
Received Access-Accept Id 186 from 172.20.66.127:1833 to 0.0.0.0:0 length 20

3,服務端的日誌爲：

Wed Jul 18 16:18:31 2018 : Info: Need 5 more connections to reach 10 spares
Wed Jul 18 16:18:31 2018 : Info: rlm_ldap (ldap): Opening additional connection (5), 1 of 27 pending slots used
Wed Jul 18 16:18:31 2018 : Auth: (0) Login OK: [lqb (from client 172.20.66.0/24 port 0)

至此經過Windows的AD域認證完成。
