1、检查freetype是否安装
rpm -qa | grep freetype
没有的话编译freetype 这里下载
./configure --prefix=/usr/local/freetype
make && make install 即可，没有花头
2、检查libjpeg是否安装
rpm -qa | grep libjpeg
没有的话编译libjpeg 这里下载
我也没装libjpeg，下载好开始编译
jpegsrc.v6b.tar.gz
tar -xzvf jpegsrc.v6b.tar.gz
cd jpeg-6b/
./configure --prefix=/usr/local/jpeg --enable-shared
make && make install
最后一步make install 出错：
/usr/bin/install -c -m 644 jconfig.h /usr/local/jpeg/include/jconfig.h
/usr/bin/install: cannot create regular file `/usr/local/jpeg/include/jconfig.h': No such file or directory
make: *** [install-headers] Error 1
/usr/bin/install: cannot create regular file `/usr/local/jpeg/lib/libjpeg.so.62.0.0': No such file or directory
/usr/bin/install: cannot create regular file `/usr/local/jpeg/bin/cjpeg': No such file or directory
make: *** [install-lib] Error 1
难道安装程序自己新建一下目录都不行？？晕，我自己去新建目录
mkdir -p /usr/local/jpeg/include
mkdir -p /usr/local/jpeg/lib
mkdir -p /usr/local/jpeg/bin
mkdir -p /usr/local/jpeg/man/man1
OK再编译就成功了
3、检查是否安装了libpng
rpm -qa libpng
没有的话编译libpng 这里下载
./configure --prefix=/usr/local/png
make && make install
4、安装GD库 这里下载
tar -zxvf gd-2.0.35.tar.gz
cd gd-2.0.35
./configure --prefix=/usr/local/gd2
5、编译PHP
