GraphicsMagick 安装
下载软件：download:ftp://ftp.graphicsmagick.org/pub/GraphicsMagick/1.3/GraphicsMagick-1.3.18.tar.gz
#如果需要支持JPEG则需要执行这一步，建议执行。（JPEG v1 --with-jpeg=yes yes ）
yum install -y libjpeg-devel libjpeg
安装软件：
tar xf GraphicsMagick-1.3.18.tar.gz
cd GraphicsMagick-1.3.18
./configure --prefix=/usr/local/GraphicsMagick-1.3.18 --with-quantum-depth=8 --enable-shared --enable-static
此处也可以默认 ./configure 就好
make
make install
至此 安装完毕，可以测试看看了。
#############################下面是 ./configure 后的返回信息，如果需要什么在自己补充吧这里我就需要这些就ok了。##########################

gm convert 111.jpg -resize 100x100 out.jpg
如果报错：
1）如果configure提示“configure: error: libltdl is required for modules build”，则yum install libtool-ltdl libtool-ltdl-devel
