What version of frp are you using (./frpc -v or ./frps -v)?
0.13.0_linux_amd64

What operating system and processor architecture are you using (go env)?
CentOS 7 (VPS), virtual cpu, 64bit

Configures you used:
The following is the configuration in frps.ini
[common]
bind_port = 7000
vhost_http_port = 80
vhost_https_port = 443
......
[web_http]
type = http
custom_domains = xxx.example.com

[web_https]
type = https
custom_domains = xxx.example.com
......

Steps to reproduce the issue:

create a new user for FRP
sudo useradd -M -s /usr/sbin/nologin -d /usr/local/frp frp
install and config authbind:
yum install authbind
sudo touch /etc/authbind/byport/{80,443}
sudo chown frp.frp /etc/authbind/byport/{80,443}
sudo chmod 755 /etc/authbind/byport/{80,443}
run FRP by the user frp in server
sudo -u frp authbind --deep /path/to/frps -c /path/to/frps.ini &

Describe the results you received:
Unable to bind to 80, permission denied

Describe the results you expected:
Binding to 80 by the general user frp successfully

Additional information you deem important (e.g. issue happens only occasionally):
No apache, nginx or other program is listening on 80 or 443.

Can you point out what caused this issue (optional)
No
