Permission denied in CentOS7 when creating a new process

[MrQuansy]

In production environment, we can not always get a 'sudo permission' all the time. I find py-spy can run through starting a new process without root permission as document said. But permission denied occurred when I tried it.

Take a look at https://man7.org/linux/man-pages/man7/capabilities.7.html and https://www.vultr.com/docs/working-with-linux-capabilities/

My guess is that you need to add cap_sys_ptrace
