环境:Centos7.5
首先进入容器:
docker exec -it myphp7 /bin/bash
先添加软件源(我在这里浪费了很长时间,先后使用163和aliyun的源都报各种错误,直到使用中科大的源才可以)
echo "deb http://mirrors.ustc.edu.cn/debian stable main contrib non-free" > /etc/apt/sources.list \ > && echo "deb-src http://mirrors.ustc.edu.cn/debian stable main contrib non-free" >> /etc/apt/sources.list \ > && echo "deb http://mirrors.ustc.edu.cn/debian stable-proposed-updates main contrib non-free" >> /etc/apt/sources.list \ > && echo "deb-src http://mirrors.ustc.edu.cn/debian stable-proposed-updates main contrib non-free" >> /etc/apt/sources.list
更新
apt-get update
安装必要的支持库
apt install -y libfreetype6 libwebp-dev libjpeg-dev libpng-dev
解压并切换目录
docker-php-source extract
cd /usr/src/php/ext
开始安装
docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ --with-png-dir=/usr/include
docker-php-ext-install gd
看到如下提示表示安装成功:
Libraries have been installed in: /usr/src/php/ext/gd/modules
重启容器
docker restart myphp7 docker ps
打开浏览器查看phpinfo(),查看GD模块是否已经安装成功。
