我正在尝试使用 Nginx 和 PHP7 在 Docker 上设置 Magento2。

我已按照 PHP7 Docker image 的建议添加了一个自定义 php.ini 文件。 .我可以从 phpinfo.php 看到它正在加载我的 php.ini 文件，但我的更新都没有。

应该是:

memory_limit = 2G
max_execution_time = 800

我检查了 PHP 容器，可以看到 php.ini 文件的设置正确，或者我认为是这样？

$ 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？以下是更多详细信息，在此先感谢!

更新

我试过用下面的方法重启nginx，但是没用。

$ docker exec -it mymagento2docker_php_1 /bin/bash 
# /etc/init.d/nginx restart                                                                                                                       
bash: /etc/init.d/nginx: No such file or directory
# service nginx restart    
nginx: unrecognized service
# nginx -s reload          
bash: nginx: command not found
# exit
$ docker restart mymagento2docker_nginx_1

$ docker exec -it mymagento2docker_nginx_1 /bin/bash

最佳答案

在 docker-compose.yml 文件中将 volumes: 部分添加到您的 php 服务，使用 映射本地目录>custom.ini 文件到 /usr/local/etc/php/conf.d，然后重启你的容器。该文件中的任何有效设置都将覆盖主 php.ini 文件中的设置。 (顺便说一句，你可以用 MySQL 做同样的事情，但不能用 Nginx)。

这适用于我自己的项目:

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

关于php - 无法更新 Docker 容器中的 php.ini 文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39875543/
