How to properly configure XDebug in PHPStorm?

Question

xdebug

There is a remote server, XDebug is configured on it (see settings below). PHPStorm set up according to this article - habrahabr.ru/post/250323
I did not specify IDEKey. Explain, there is php.ini on a remote server and I have it on my computer - in the storm in the php settings I specified the local path to php. What to register on a remote server and what on a local one in php.ini? Which remote_host? And also, I have Internet through a router, how to forward the port correctly? TCP?
I also read that remote_autostart=1 loads the server, is that so? How can I set xdebug to work only with me?
Local php.ini

[XDebug]
zend_extension = "D:\programs\php\ext\php_xdebug.dll"
xdebug.profiler_append = 0
xdebug.profiler_enable = 1
xdebug.profiler_enable_trigger = 0
xdebug.profiler_output_dir = "D:\programs\php\tmp"
xdebug.profiler_output_name = "cachegrind.out.%t-%s"
xdebug.remote_autostart =0
xdebug.remote_port = 9000
xdebug.remote_enable = 1
xdebug.remote_handler = "dbgp"
xdebug.remote_host = "te****.ru"
xdebug.trace_output_dir = "D:\programs\php\tmp"
xdebug.output_buffering = 0

Answer 1

when working with a remote host via the Internet, you need to have a white IP address (i.e. one that can be pinged from any other host on the Internet)
if it is assigned to a router, then it is on the router to configure the port forwarding of the port used by xdebug (by default - 9000 ) to your machine on the local network.
it is the white IP that should appear as remote_host on the remote server.
and yes, autostart slows down the server, because even if you don't "listen" to xdebug, it starts and hits the port specified in the settings on the specified host.
connection there UDP.
and in general - it is better not to do so. =)
