解决

先找到/usr/local/etc/raddb/radiusd.conf，看看$INCLUDEsql.conf前的注释是否去掉，若去掉还不行就按一下方法做。

1.如果你是使用mysql源码编辑方式安装的mysql，应该不会出现这个问题，如果你是用类似rpm模式安装的mysql，那么默认是不会安装rlm\_sql\_mysql.so的，如果需要这个文件就要补充安装mysql-devel-\*\*\*\*.rpm

2.上网址：[http://dev.mysql.com/doc/refman/5.1/en/linux-rpm.html][http_dev.mysql.com_doc_refman_5.1_en_linux-rpm.html]下载该包。

3.到源代码树：freeradius-server\*\*\*\*/src/modules/rlm\_sql/drivers/rlm\_sql\_mysql里再进行编译,之后会在freeradius-server-2.1.1/src/modules/rlm\_sql/drivers/lib中生成rlm\_sql\_mysql.so，把它拷贝到/usr/lib下即可”

rlm\_sql\_mysql-2.2.0.la  
rlm\_sql\_mysql-2.2.0.so  
rlm\_sql\_mysql.a  
rlm\_sql\_mysql.la  
rlm\_sql\_mysql.so  
到
