php - Docker-Symfony 项目上的 Web 服务器无法启动

Question

我正在习惯 Docker-compose，并决定使用 Symfony-framework 为 PHP/SQL/WEB 设置环境。我找到了这个web-site指导我如何去做。嗯，我做了一些，但我遇到了一些问题:

• 我必须修改 docker-compose.yml 文件并将 Web 服务器端口设置为“”而不是“”(据我研究)
• MySQL 服务器无法启动(参见下面的日志)

控制台日志:

The MYSQL_ROOT_PASSWORD variable is not set. Defaulting to a blank string.
The MYSQL_ROOT_HOST variable is not set. Defaulting to a blank string.

• default_symfony
• php-fpm.conf
• www.conf

试试这个。 https://github.com/coloso/symfony-docker几乎相同，并且在这里工作得很好(您需要手动退出第一个命令“docker-compose up --build”，但一切都很好)。 mysql高于5.7的docker问题也很多。所以就用5.7吧。最好的问候
