无法更新 Docker 容器中的 php.ini 文件 [英] can't update php.ini file in Docker container
问题描述
我正在尝试使用 Nginx & 在 Docker 上设置 Magento2PHP7.
I'm trying to set Magento2 on Docker with Nginx & PHP7.
按照
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?
I've checked the PHP container and I can see the php.ini file is there with the correct settings, or so I think?
$ 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！
What am I doing wrong? Below are some more details, thanks in advance!

更新
我试过用下面的方法重启nginx，但是没用.
UPDATE
I've tried restarting nginx with the below, but it did not work.
$ 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
mymagento2docker_nginx_1
$ docker exec -it mymagento2docker_nginx_1 /bin/bash
# /etc/init.d/nginx restart

推荐答案
在 docker-compose.yml 中的 php 服务中添加 volumes: 部分 文件，将带有 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).
Add a volumes: section to your php service in the docker-compose.yml file, map a local directory with a custom.ini file to /usr/local/etc/php/conf.d, and restart your container. Whatever valid settings in that file will override those from the main php.ini file. (Incidentally you can do the same with MySQL but not with Nginx).
这适用于我自己的项目:
This works in my own project:
<代码>php:卷:- ./localpath/custom.ini:/usr/local/etc/php/conf.d/custom.ini
