PHP无法在Docker容器中写入 [英] PHP cannot write in docker container
问题描述
我正在尝试在docker中创建工作流程。
很简单:只需PHP和MySQL即可进行少量测试。
I'm trying to create a workflow in docker. It's simple: just PHP and MySQL to little tests.
我的 docker-compose.yml :
web:
build: .docker
links:
- mysql:mysql
ports:
- "80:80"
- "443:443"
volumes:
- ./public_html:/var/www/html
mysql:
image: mysql:5.7
environment:
- MYSQL_ROOT_PASSWORD=root
volumes:
- "./.data/db:/var/lib/mysql"
phpmyadmin:
image: phpmyadmin/phpmyadmin
ports:
- "8080:80"
links:
- mysql:mysql
environment:
- PMA_HOST=mysql
volumes:
- /sessions
和我的 Dockerfile :
FROM php:5.6-apache
RUN docker-php-ext-install mysqli
没关系:我可以打开容器,但是PHP本身不能写在目录中(例如 fwrite()
或类似)。
It's all ok: I can up containers but PHP itself cannot write in directories (like fwrite()
or similar).
我研究了很多,并尝试了很多教程,但是什么也没有。
I researched a lot and tried a lot of tutorials, but nothing...
推荐答案
Apache使用用户运行PHP www-data
,此用户需要在您的主机目录中具有写权限。/public_html
Apache runs PHP with the user www-data
, this user needs to have write access on your host directory ./public_html
要解决此问题,请转到docker-compose目录并执行以下命令,以更改 public_html
目录的所有者以及其中的所有文件。
To fix that, go to your docker-compose directory and execute the following command to change the owner of your public_html
directory and all files inside.
sudo chown -R www-data:www-data public_html
之后,您需要允许 www-data组中的用户编辑文件
After that you need to allow users in the group "www-data" to edit files
# To change all the directories to 775
# (write for user & group www-data, read for others):
find public_html -type d -exec chmod 775 {} \;
# To change all the files to 664
# (write for user & group www-data, read for others):
find public_html -type f -exec chmod 664 {} \;
为当前用户编辑这些文件您需要将其添加到 www-data
组:
sudo usermod -aG www-data $USER
