php-fpm:mods available/xdebug.ini中的设置无效

Question

我正试图通过编辑可用的mods/xdebug.ini来应用自定义xdebug设置，但当我重新启动php-fpm时，只应用了默认设置。错误日志中没有可见的相关错误。

没有应用自定义设置的原因是什么？

zend_extension=xdebug.so
xdebug.remote_enable=on
xdebug.default_enable=on
xdebug.remote_autostart=off
#The default port 9000 doesn’t work as some other service (don’t remember which one) is using it as well
xdebug.remote_port=10000
#phpstorm's xdebug validate tool suggests:
#xdebug.remote_host=172.27.0.1
#but it's not working
#on mac you have to use this for docker
#xdebug.remote_host=docker.for.mac.localhost
#or (is the more recent one):
xdebug.remote_host = host.docker.internal

Answer 1

当试图找出哪些模块是通过php-cli命令启用的"php-m"；我得到了一个启用模块的列表，但列表上方也有一条错误消息：

PHP:  syntax error, unexpected '(' in /etc/php/7.4/cli/conf.d/20-xdebug.ini on line 5

它指出，#字符并没有被解释为注释的开头。所以，经过短暂的谷歌搜索，我发现必须使用分号来屏蔽ini文件中的注释：

zend_extension=xdebug.so
xdebug.remote_enable=on
xdebug.default_enable=on
xdebug.remote_autostart=off
;The default port 9000 doesn’t work as some other service  (don’t remember which one)  is using it as well
xdebug.remote_port=10000
;phpstorm's xdebug validate tool suggests:
