[BigHoney15]

In centos7 system, lsof has been installed in root using yum. But in the services start section, there is still a problem that lsof "command not found". How to solve this problem?

centos7系统，在运行services start部分，已在root中用yum安装了lsof，但还是会出现lsof未找到命令的问题，应该怎么解决？

try exec:
lsof -i:8080
directly from shell to check if lsof correctly installed.

and try exec:
ssh localhost "lsof -i:8080"
again to check if losf is in search path when exec by ssh
