ZConfig.ConfigurationError: There was a problem starting a server of type "HTTPServer". This may mean that your user does not have permission to bind to the port which the server is trying to use or the port may already be in use by another application. (Address already in use)
回答1:
If you did not change the Plone configuration, it is trying to bind to port 8080. The error message indicates the port is already in use.
The most common reason is that this or another Plone instance is using the port. If you don't have another Plone install, then it may be the current Plone install, with the Plone daemon running as a background process. Try using bin/instance stop.
If that doesn't work and this is a development machine that you control, you may wish to simply reboot it. Otherwise, use your operating system's process-monitor mechanisms (ps aux | grep python on a Linux system) to find out if Plone is already running. If so, kill the process.
Plone is not the only package that uses 8080 as its default port. If the above has failed, use a network monitor program (netstat or sockstat on a Linux system) to track down the other process listening on the port. Change its configuration or Plone's.
回答2:
sudo netstat -lnap | grep 8080
Check which process is using the port 8080 and use "kill " command to kill it and then again restart it.

I was facing the same error. I got some hint from this post http://plone.293351.n2.nabble.com/Address-Already-in-Use-error-td328781.html
I went to back to my command and seen that I was using wrong user in command with sudo.
sudo -u plone_daemon bin/instance fg --- Wrong command
sudo -u [Change_user_respectively] bin/instance fg -- It worked for me.
