这个安装并调试比较简单，先安装后进行本地认证测试，如果成功的话证明各个组件都是没有问题，然后再调试连接mysql，网上的教程都是从安装mysql开始的，其实没有这个必要，完全可以从现有的mysql数据库进行连接，省去安装mysql的步骤。在你现有的数据库建立radius数据库，然后运行如下sql指令，复制文本保存为sql文件并执行

以上！
这里就完成了freeradius所需的mysql准备，下面安装freeradius
1、安装
apt-get update
apt-get install freeradius freeradius-mysql freeradius-utils -y
2、设置连接到mysql
cd /etc/freeradius/3.0/mods-enabled
ln -s ../mods-available/sql sql
3、修改sql配置文件
cd /etc/freeradius/3.0/mods-available
nano sql
需修改内容如下：
driver = "rlm_sql_mysql"
dialect = "mysql"
server = "你的mysql地址"
port = 3306
login = "你的mysql用户名"
password = "你的mysql密码"
radius_db = "radius"
read_clients = yes
4、配置freeradius文件
cd /etc/freeradius/3.0/sites-available/
nano default
删除file的选项并核实sql选项
authorize {
.....
sql
....
}
accounting {
......
sql
....
}
post-auth {
......
sql
....
}
session{
......
sql
.....}
以上，安装配置完成，使用
freeradius -X
进入debug模式查看整个认证的过程。
在数据库的radcheck添加一条记录
insert into radcheck VALUES('2','te1st','Cleartext-Password',':=','123123')
id注意不要重复了
这个时候另外连接一个服务器的CLI，使用如下命令进行测试
radtest test 123123 localhost 1812 testing123
如果返回 Access-Accept got Access-Reject说明认证失败，检查配置
如果返回Received Access-Accept说明认证成功。
下面就可以对VPN服务器进行配置连接到freeradius进行认证了。详情看下篇文章。
