#調整FreeRadius啟動順序
FreeRadius必須在資料庫啟動之後啟動，在[Unit]部分，增加After=mariadb.service，如下圖所示：
# vim /etc/systemd/system/multi-user.target.wants/radiusd.service
After=mysqld.service
[Unit]
Description=FreeRADIUS high performance RADIUS server.
After=syslog.target network.target ipa.service dirsrv.target krb5kdc.service mysqld.service
