我正在恢复一个仍使用 PHP5.6 和 mysql_connect 的旧网站，以更新其代码。
我打算使用 PHP 5.6 设置一个 docker 环境，以确保一切正常，然后再进行急需的更新。
但是我在安装 mysql 驱动程序时遇到了困难。
这是我的 docker-compose.yml
version: '3'
services:
db:
image: mysql:5.5
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: "edited for privacy"
MYSQL_DATABASE: "edited for privacy"
MYSQL_USER: "edited for privacy"
MYSQL_PASSWORD: "edited for privacy"
php:
depends_on:
- db
build: .
volumes:
- ./:/var/www/html
ports:
- "8000:80"
restart: always
volumes:
db_data: {}
使用第一个 dockerfile，我遇到以下错误

RUN apt-get install mysql-server mysql-client php5-mysql
RUN a2enmod rewrite
docker compose up -d

我以为我必须先更新，但后来我遇到了这个错误，我不知道该怎么办。

我不知道下一步该怎么做，非常欢迎任何帮助。
从上面的错误消息来看，不支持命令“q”参数。您可以按照建议尝试使用选项 -c / -p 等
0 0.281 su: invalid option -- 'q'

#0 0.281 -c, --command COMMAND pass COMMAND to the invoked shell
