vpn默认需要在配置文件里面添加用户密码，如果用户离职啊，新员工入职等情形，对一些不懂技术的管理人员，去修改配置文件，显然不太合理。所以，需要一套非技术人员也能操作的web管理系统来管理用户。
工具介绍：
freeradius一般用来进行账户认证管理，记账管理，常见的电信运营商的宽带账户，上网账户管理，记账，都是使用的radius服务器进行鉴权记账的。
Freeradius包含一个radius服务器和radius-client，可以对支持radius协议的网络设备进行鉴权记账，常见的开源路由器操作系统：如Openwrt,DD-wrt等，都支持radius协议，对PPPOE，热点，VPN等服务器进行账户管理认证，记账。
freeradius功能十分强大，支持众多的数据库。
Freeradius操作稍显麻烦，内置diaup_admin简单web管理，需要更简单易用的管理功能可以使用第三方的管理程序对Freeradius进行账户管理，系统配置等。
daloRADIUS是高级的RADIUS页面管理应用目的是对于hotspots和ISP的部署进行管理。同时还提供了用户管理，图形化的报告、报表引擎以及于google地图的集成。
本文以l2tp为例，其他类似。
前提：
安装好vpn,mysql
安装步骤：
在开始安装之前，建议关闭SELinux或将其设置为disabled，最好建议永久关闭SELinux
sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config
临时关闭 setenforce 0
一、FreeRADIUS 服务端安装
1.1 下载、编译、安装
wget -c ftp://ftp.freeradius.org/pub/freeradius/freeradius-server-3.0.17.tar.gz
tar zxf freeradius-server-3.0.17.tar.gz
cd freeradius-server-3.0.17
./configure
make && make install
一般安装过程中提示缺少libtalloc 库，需要安装talloc-2.1.7.tar.gz
先从 https://www.samba.org/ftp/talloc/talloc-2.1.13.tar.gz 下载 talloc-2.1.13.tar.gz 然后安装.
1.2 测试是否安装成功
vi /usr/local/etc/raddb/users
在第一行添加
steve Cleartext-Password := "testing"
退出后命令行执行 radiusd -X
另外一个窗口执行radtest steve testing localhost 0 testing123
看到 "Access-Accept packet" 表示成功了，"Access-Reject" 表示失败了。
成功后去掉上面的那一行配置。
备注：服务端如果编译安装不通过，也可以通过yum安装.
yum -y install freeradius freeradius-utils freeradius-mysql
1.3 配置radius
cd /usr/local/etc/raddb/sites-enabled
vi default
将authorize {}下的sql去掉注释，并且将file注释掉。
cd /usr/local/etc/raddb/mods-available
vi sql
找到driver = “rlm_sql_null”这一行，修改为driver = “rlm_sql_mysql”。保持并退出。
去掉注释，设置用户名和密码等信息
修改 FreeRADIUS中的mysql 认证配置
执行如下命令：
cd /etc/raddb/mods-enabled
ln -s ../mods-available/sql
二、FreeRADIUS 客户端安装与配置
2.1 编译与安装
wget -c ftp://ftp.freeradius.org/pub/freeradius/freeradius-client-1.1.7.tar.gz
tar -zxf freeradius-client-1.1.7.tar.gz
cd freeradius-client-1.1.7
./configure
make && make install
2.2 设置通信密码
vi /usr/local/etc/radiusclient/servers
添加一行
localhost testing123
2.3 增加字典
wget -c http://small-script.googlecode.com/files/dictionary.microsoft
mv ./dictionary.microsoft /usr/local/etc/radiusclient/
vi /usr/local/etc/radiusclient/dictionary
最后添加
INCLUDE /usr/local/etc/radiusclient/dictionary.sip
INCLUDE /usr/local/etc/radiusclient/dictionary.ascend
INCLUDE /usr/local/etc/radiusclient/dictionary.merit
INCLUDE /usr/local/etc/radiusclient/dictionary.compat
INCLUDE /usr/local/etc/radiusclient/dictionary.microsoft
2.4增加ppp插件配置
vi /etc/ppp/options.xl2tpd
最后添加
plugin /usr/lib64/pppd/2.4.5/radius.so
plugin /usr/lib64/pppd/2.4.5/radattr.so
radius-config-file /usr/local/etc/radiusclient/radiusclient.conf
pppd的radius.so根据路径配置，如果没有搜到，安装一下pppd
三 配置mysql
3.1 创建radius库
#mysql -uroot -p
mysql>create database radius;
3.2 创建radius用户
mysql>grant all on radius.* to radius@localhost identified by 'radius';
mysql>flush privileges;
3.3 导入sql文件
#cd /usr/local/etc/raddb/mods-config/sql/main/mysql
#mysql -u radius -p radius<schema.sql
3.4 初始设置MySQL，设置root密码,出于安全考虑，考虑删除匿名用户和禁用远程根登录,参见下面的示例配置。
# mysql_secure_installation
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] y
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y
四. 安装apache
yum -y install httpd httpd-devel
设置开机启动和启动Apache服务
# systemctl enable httpd
# systemctl start httpd
五. 安装php7
# curl 'https://setup.ius.io/' -o setup-ius.sh
# bash setup-ius.sh
# yum remove php-cli mod_php php-common
# yum -y install mod_php70u php70u-cli php70u-mysqlnd php70u-devel php70u-gd php70u-mcrypt php70u-mbstring php70u-xml php70u-pear
六 安装FreeRADIUS管理界面Daloradius
进入Apache网站根目录,下载源文件
# cd /var/www/html/
# wget https://github.com/lirantal/daloradius/archive/master.zip
# unzip master.zip
# mv daloradius-master/ daloradius
# wget http://liquidtelecom.dl.sourceforge.net/project/daloradius/daloradius/daloradius0.9-9/daloradius-0.9-9.tar.gz
# unzip master.zip
# mv daloradius-master/ daloradius
进入daloradius目录，导入daloradius数据库
# cd daloradius
# mysql -u root -p radius < contrib/db/fr2-mysql-daloradius-and-freeradius.sql
# mysql -u root -p radius < contrib/db/mysql-daloradius.sql
设置daloradius目录用户组和用户，设置daloradius.conf.php权限
# chown -R apache:apache /var/www/html/daloradius/
# chmod 664 /var/www/html/daloradius/library/daloradius.conf.php
设置daloradius数据库连接信息，打开daloradius.conf.php文件,修改CONFIG_DB_USER，CONFIG_DB_PASS，CONFIG_DB_NAME。
# vi /var/www/html/daloradius/library/daloradius.conf.php
填入mysql的用户密码和数据库名称
重启服务
# systemctl restart xl2tpd
# systemctl restart mysql
# systemctl restart httpd
# cp /usr/local/sbin/rc.radiusd /etc/init.d/radiusd
/etc/init.d/radiusd start
- 安装php-pear
# yum install php-pear
# pear install DB
登录web界面
默认用户名: administrator
密码: radius
http://ip-address/daloradius/login.php
安装后可以在界面进行添加用户，用添加的用户登陆vpn
如果连接时后台/var/log/messages如下错误：
rc_read_dictionary: invalid type on line 92 of dictionary /usr/local/etc/radiusclient/dictionary
将dictionary内容替换如下：
#
# Updated 97/06/13 to livingston-radius-2.01 miquels@cistron.nl
#
# This file contains dictionary translations for parsing
# requests and generating responses. All transactions are
# composed of Attribute/Value Pairs. The value of each attribute
# is specified as one of 4 data types. Valid data types are:
#
# string - 0-253 octets
# ipaddr - 4 octets in network byte order
# integer - 32 bit value in big endian order (high byte first)
# date - 32 bit value in big endian order - seconds since
# 00:00:00 GMT, Jan. 1, 1970
#
# Enumerated values are stored in the user file with dictionary
# VALUE translations for easy administration.
#
# Example:
#
# ATTRIBUTE VALUE
# --------------- -----
# Framed-Protocol = PPP
# 7 = 1 (integer encoding)
#
# The dictionary format now supports vendor-specific attributes.
# Vendors are introduced like this:
#
# VENDOR vendor_name vendor_number
#
# For example:
#
# VENDOR RoaringPenguin 10055
#
# Vendor-specific attributes have a fifth field with the name of the
# vendor. For example:
#
# ATTRIBUTE RP-Upstream-Speed-Limit 1 integer RoaringPenguin
#
# introduces a Roaring Penguin vendor-specific attribbute with name
# RP-Upstream-Speed-Limit, number 1, type integer and vendor RoaringPenguin.
#
# Following are the proper new names. Use these.
