### linux系统篇

### 1.CentOS系统

### 关于GD扩展

gd扩展是一个开源的图像处理库，它通过提供一系列用来处理图片的API，使其可以用来创建图表、图形、缩略图以及其他图像的处理操作。gd扩展支持JPG、PNG、GIF等常见的图片格式，所以在安装php-gd扩展之前，我们需要安装libpng、jpegsrc、freetype这三款软件。下面安装步骤中，具体的路径设置大家根据自己的实际情况进行调整。

**一，首先安装以下内容**

### 安装 freetype

wget http://ftp.twaren.net/Unix/NonGNU/freetype/freetype-2.5.5.tar.gz
tar -xf freetype-2.5.5.tar.gz
cd freetype-2.5.5
./configure --prefix=/usr/local/freetype
make && make install

### 安装jpegsrc

wget http://www.ijg.org/files/jpegsrc.v9.tar.gz
tar zxvf jpegsrc.v9.tar.gz
cd jpeg-9
./configure --prefix=/usr/local/jpeg
make && make install

### 安装libpng

wget http://jaist.dl.sourceforge.net/project/libpng/libpng16/1.6.31/libpng-1.6.31.tar.gz
tar zxvf libpng-1.6.31.tar.gz 
cd libpng-1.6.31
./configure --prefix=/usr/local/libpng
make && make install

### 二，安装GD扩展

首先最基本的

第一：先安装库

yum -y install libjpeglibjpeg-devel libpng libpng-devel freetype freetype-devel

第二：进入PHP源码目录下的etc/gd目录

find / -name gd

cd /usr/local/php-7.1.16/ext/gd

执行phpize

find / -name phpize

/usr/local/php/bin/phpize

执行configure：

注：这里的–with-php-config目录根据自己php的安装路径配置

find / -name php-config

![](https://img2018.cnblogs.com/blog/1067925/201902/1067925-20190227154745203-768217764.png)

./configure –with-png-dir –with-freetype-dir –with-jpeg-dir –with-gd –with-php-config=/usr/local/php/bin/php-config

注意了：

# configure: error: jpeglib.h not found

解决方案：

执行

rpm -qa | grep libjpeg

yum -y install libjpeg-devel

yum list installed | grep libjpeg

再次执行

./configure –with-png-dir –with-freetype-dir –with-jpeg-dir –with-gd –with-php-config=/usr/local/php/bin/php-config

执行：make && make install

cd /usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/

ls
