1、先配置阿里云镜像源

cd /etc/apt
echo ""  > sources.list
echo "deb http://mirrors.aliyun.com/debian/ bullseye main contrib" >> /etc/apt/sources.list
echo "deb-src http://mirrors.aliyun.com/debian/ bullseye main contrib" >> /etc/apt/sources.list
echo "deb http://mirrors.aliyun.com/debian/ bullseye-updates main contrib" >> /etc/apt/sources.list
echo "deb-src http://mirrors.aliyun.com/debian/ bullseye-updates main contrib" >> /etc/apt/sources.list
echo "deb http://mirrors.aliyun.com/debian/ bullseye-backports main contrib" >> /etc/apt/sources.list
echo "deb-src http://mirrors.aliyun.com/debian/ bullseye-backports main contrib" >> /etc/apt/sources.list
echo "deb http://mirrors.aliyun.com/debian/ bullseye-proposed-updates main contrib" >> /etc/apt/sources.list
echo "deb-src http://mirrors.aliyun.com/debian/ bullseye-proposed-updates main contrib" >> /etc/apt/sources.list

2、安装需要的依赖库，这里要加个 --allow-unauthenticated 不然会有一些不必要的报错

# 安装依赖库
apt-get update && apt-get install -y --allow-unauthenticated \zlib1g \libpng-dev \libjpeg-dev \libfreetype6-dev \libwebp-dev \zlib1g-dev

3、安装gd，这里要用  docker-php-ext-configure 和 docker-php-ext-install

docker-php-ext-configure gd --with-freetype --with-jpeg --with-webp --with-zlib
docker-php-ext-install gd

4、安装mysql扩展

docker-php-ext-install pdo pdo_mysql
