Xdebug 无法连接到调试客户端。 试过：本地主机：9000

Question

I used before Xdebug v2, but after last update I faced with Xdebug v3.0.0, I replaced all what needed by the update user guide

I'm using Docker.

my debug conf

#xdebug.remote_enable=true
xdebug.mode=debug

#xdebug.remote_port=9000
xdebug.client_port=9000

xdebug.remote_host=172.17.0.1

xdebug.remote_handler=dbgp

#xdebug.remote_autostart=1
xdebug.start_with_request=yes

#xdebug.remote_connect_back=0
xdebug.discover_client_host=0

xdebug.idekey=PHPSTORM
xdebug.show_error_trace = 1
xdebug.max_nesting_level=250
xdebug.var_display_max_depth=10
#xdebug.remote_mode=req

xdebug.remote_log=/var/log/r_xdebug.log
xdebug.log=/var/log/xdebug.log

and what I get in log when try to execute any PHP script:

tail -f /var/log/xdebug.log
[888] Log opened at 2020-11-29 10:39:51.670762
[888] [Step Debug] INFO: Connecting to configured address/port: localhost:9000.
[888] [Step Debug] WARN: Creating socket for 'localhost:9000', poll success, but error: Operation now in progress (29).
[888] [Step Debug] WARN: Creating socket for 'localhost:9000', connect: Cannot assign requested address.
[888] [Step Debug] ERR: Could not connect to debugging client. Tried: localhost:9000 (through xdebug.client_host/xdebug.client_port) :-(
[888] Log closed at 2020-11-29 10:39:57.515970

When I try to execute the URL in a browser PhpStorm does not start debugger, but I checked

lsof -i :9000 | grep LISTEN

listen port appeared when I click listening in PhpStorm. My conf was sync File | Settings | Languages & Frameworks | PHP | Debug File | Settings | Languages & Frameworks | PHP | Debug File | Settings | Languages & Frameworks | PHP | Debug -> Debug port 9000

What's wrong with my Xdebug config and what I need to do?

Answer 1

I just want to share how I migrated from 2.x to 3.x

;Xdebug 2.X
;xdebug.remote_enable=true
;xdebug.remote_port=9000
;xdebug.remote_host=172.17.0.1
;
;xdebug.remote_autostart=1
;xdebug.remote_connect_back=0
;xdebug.idekey=PHPSTORM
;xdebug.show_error_trace = 1
;xdebug.max_nesting_level=250
;xdebug.var_display_max_depth=10
;xdebug.remote_mode=req


;Xdebug 3.X
xdebug.mode=debug
xdebug.client_port=9000
xdebug.client_host=172.17.0.1
xdebug.remote_handler=dbgp
xdebug.start_with_request=yes
xdebug.discover_client_host=0
xdebug.idekey=PHPSTORM
xdebug.show_error_trace = 1
xdebug.max_nesting_level=250
xdebug.var_display_max_depth=10
xdebug.log=/var/log/xdebug.log

Answer 2

Please, update your xdebug file to:

xdebug.mode=debug
xdebug.start_with_request=yes
xdebug.discover_client_host=1

Answer 3

I found that using

xdebug.log_level=0

stopped the excess logs.
