在centos7上安装freeradius

1. yum安装

yum install freeradius

2. 编译安装

获取最新的稳定版本:

官网下载地址https://freeradius.org/releases/或者https://freeradius.org/ftp/pub/freeradius/

先安装依赖 libtalloc-devel

yum -y install libtalloc-devel

解压freeradius-server-3.0.21.tar.gz

tar -vxf freeradius-server-3.0.21.tar.gz
cd freeradius-server-3.0.21/
./configure
make
sudo make install

如果遇到

configure: error: FreeRADIUS requires libtalloc

解决办法：

安装libtalloc-devel:
yum install -y libtalloc-devel

问题解决,再次./configure，没有再打印这个错误信息，说明这个问题解决,而是打印了下一个错误信息:

checking for utmpx.h... yes
checking winsock.h usability... no
checking winsock.h presence... no
checking for winsock.h... no

configure: error: in `/opt/vsftp/he/freeradius-server-3.0.12':

See `config.log' for more details
[root@fedora freeradius-server-3.0.12]#

错误信息显示链接不到libcrypto

执行 rpm -qa |grep libcrypto
查看有没有返回信息，没有返回就是没有安装。
libcrypto包含在openssl安装包里，OpenSSL 包含2个主要的库: libssl 和 libcrypto.

解决办法就是安装openssl:

yum install openssl openssl-devel

运行./configure显示这个问题解决,并且没有报其它错误信息

至此,./configure执行成功

接下来执行make命令

如果遇到error: efusing to start with libssl version OpenSSL ， 进入etc/raddb下找到radiusd.conf将allow_vulnerable_openssl = no 修改为allow_vulnerable_openssl = yes即可。

查看版本：

radiusd -v
