freeradius:rlm_sql_mysql.so: cannot open shared object file

当搭建radius+mysql时会遇到这个错误

Error: rlm_sql (sql): Could not link driver rlm_sql_mysql: rlm_sql_mysql.so: cannot open shared object file: No such file or directory

问题产生的原因是编译的时候没有加载到mysql库，我的解决办法是

ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql

ln -s /usr/local/mysql/include/mysql /usr/include/mysql

上述路径根据自己环境写

正常启动的输入日志
