尝试在 Docker 官方镜像中将 freetype 添加到 php-gd 中
我正在尝试为PHP GD安装添加一些功能。我使用Docker PHP“官方”版本作为基础(php:7.1.15-fpm-jessie)。
我目前的生产环境使用CentOS,GD模块附带FreeType,JPEG和PNG支持,正如你在phpinfo输出中看到的那样:
GD Support => enabled
GD headers Version => 2.2.5
GD library Version => 2.2.5
FreeType Support => enabled
FreeType Linkage => with freetype
FreeType Version => 2.4.11
GIF Read Support => enabled
GIF Create Support => enabled
JPEG Support => enabled
libJPEG Version => 6b
PNG Support => enabled
libPNG Version => 1.5.13
WBMP Support => enabled
XPM Support => enabled
libXpm Version => 30411
XBM Support => enabled
WebP Support => enabled
Directive => Local Value => Master Value
gd.jpeg_ignore_warning => 1 => 1
但是这个 Docker 镜像没有 FreeType 和 JPEG 支持,并且带有一个更旧版本的 GD(参见下面的 phpinfo 波纹管):
GD Support => enabled
GD Version => bundled (2.1.0 compatible)
GIF Read Support => enabled
GIF Create Support => enabled
PNG Support => enabled
libPNG Version => 1.2.50
WBMP Support => enabled
XBM Support => enabled
Directive => Local Value => Master Value
gd.jpeg_ignore_warning => 1 => 1
我需要重新编译 PHP 还是只编译扩展?该图像使用Debian Jessie。
版本(解决方案):
重新编译后,我在这篇文章中找到了最佳解决方案:
解决!Docker + PHP7 + GD 导致“调用未定义的函数 imagecreatefromjpeg()”的问题
所以我简单地添加了:
RUN apt-get update && apt-get install libgd3 libgd-dev && rm -rf /var/lib/apt/lists/*
RUN docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/
RUN docker-php-ext-install -j$(nproc) gd
在那之后,我的phpinfo开始显示:
GD Support => enabled
GD Version => bundled (2.1.0 compatible)
FreeType Support => enabled
FreeType Linkage => with freetype
FreeType Version => 2.5.2
GIF Read Support => enabled
GIF Create Support => enabled
JPEG Support => enabled
libJPEG Version => 6b
PNG Support => enabled
libPNG Version => 1.2.50
