菜鸟求救，在使用rpm -ivh ipvsadm-1.24-5.src.rpm命令时，出现以下问题：

[root@localhost src]# rpm -ivh ipvsadm-1.24-5.src.rpm
1:ipvsadm warning: user wensong does not exist - using root
warning: group wensong does not exist - using root
warning: user wensong does not exist - using root)
warning: group wensong does not exist - using root
我是以root用户名登录的，可为什么说using root
