can'；t更新Docker容器中的php.ini文件

我正试图用Nginx和PHP7在Docker上设置Magento2

我已经添加了一个定制的php.ini文件，这是。我可以从phpinfo.php中看到它正在加载我的php.ini文件，但是没有我的更新。

应该是：

memory_limit = 2G
max_execution_time = 800

我已经检查了PHP容器，我可以看到PHP.ini文件有正确的设置，或者我认为是这样的

$ docker exec -it mymagento2docker_php_1 /bin/bash 
# cat /usr/local/etc/php/php.ini                                                                                                                  
; This file is created automatically by the docker build

memory_limit = 2G
max_execution_time = 800

我做错了什么？下面是更多的细节，提前感谢

更新 我试着用下面的代码重新启动nginx，但没有成功

$ docker exec -it mymagento2docker_php_1 /bin/bash 
# /etc/init.d/nginx restart

我认为您必须重新加载nginx配置。 我不知道您的php容器使用的是哪种操作系统，但请在容器内部尝试以下操作：

# /etc/init.d/nginx restart

# service nginx restart

# nginx -s reload

我的逻辑原因是，安装php（同时启动它），然后复制新配置。

在docker-compose.yml文件中向php服务添加一个volumes:部分，将一个带有自定义.ini文件的本地目录映射到/usr/local/etc/php/conf.d，然后重新启动容器。该文件中的任何有效设置都将覆盖主php.ini文件中的设置。（顺便提一下，您可以对MySQL执行相同的操作，但对Nginx则不行）

这在我自己的项目中起作用：

php:
卷数：
-./localpath/custom.ini:/usr/local/etc/php/conf.d/custom.ini

发生了这样的事情： -如果将php.ini从主机映射到容器，请确保在启动容器之前主机上必须存在文件（php.ini）。否则，容器将无法启动 -请检查docker是否能够读取您的php.ini文件（检查权限，有时docker以不同的用户身份运行，无法访问属于root的主机文件）

---

-每次更新php.ini时，都必须重新启动php fpm（进入容器并重新启动php fpm进行测试，不要重建容器），然后清除缓存（如果启用了opcache）

我将把这些代码行放在哪里？在php/Dockerfile中？我猜没有“在他们之前”当然没有评论标签。在nginx容器中。否则，您可以尝试在php容器中使用：/etc/init.d/php7-fpm restart或服务php7-fpm restart重新启动php fpm，可能只是在没有版本号的情况下重新启动php fpm。这里是我的研究链接，感谢我尝试过，但没有任何成功，请参阅我的更新与此答案类似（足以不单独给出答案），我必须使用“apachectl restart”重新启动apache，我想详细说明您的答案，因为这对我的另一个问题有所帮助。我正在使用docker compose kill终止容器，我想知道为什么更改从未生效。因为docker compose缓存是更改的结果，所以在启动容器之前，请确保使用docker compose down强制取下容器，然后它将正确加载php.ini文件。希望这能帮我省下8个小时的头痛，谢谢！这正是我所需要的。那么，这是否只添加了您指定的设置？或者，如果您链接一个custom.ini，它将只放入您指定的设置中？另外，它可以称为custim.ini，还是应该称为php.ini？
