无法在Docker容器中更新php.ini文件

Question

我正试图用Nginx和PHP7在Docker上设置Magento2.

我已经按照PHP7 Docker镜像的建议添加了一个自定义的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.

它应该是:

memory_limit = 2G
max_execution_time = 800

我检查了PHP容器,我可以看到php.ini文件中有正确的设置,或者我认为？

$ 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

我究竟做错了什么？以下是一些更多细节,提前感谢!

UPDATE

我尝试用下面的方法重新启动nginx,但它没有用.

$ 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

Answer 1

在docker-compose.yml文件中向您的php服务添加一个卷:部分,将一个带有custom.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.(顺便说一句,你可以用MySQL做同样的事情但不能用Nginx做同样的事情).

这适用于我自己的项目:

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

Answer 2

我认为你必须重新加载 nginx 配置。我不知道您的 php 容器使用哪个操作系统，但请在容器内部尝试其中一些：

# /etc/init.d/nginx restart

# service nginx restart

# nginx -s reload

我的逻辑原因是，您安装 php （并同时启动它），毕竟您复制了新配置。
