详细配置步骤：
lua+nginx+GraphicsMagick
环境： CentOSsh5.4_x64.iso
虚拟机： Vmware9.0
yum install readline-devel pcre-devel openssl-devel
cd /opt/Source
wget http://agentzh.org/misc/nginx/ngx_openresty-1.0.15.10.tar.gz
useradd -r www
tar vxzf ngx_openresty-1.0.15.10.tar.gz
cd ngx_openresty-1.0.15.10
./configure --user=www --group=www --prefix=/usr/local/openresty \
--with-luajit \
--without-http_redis2_module \
--with-http_iconv_module
make -j4
# -j后面的cpu核心数，如果是多核可以写相应的个数
make install
安装jpg环境：
tar xf libjpeg-6b.tar.gz
./configure
make && make install
tar xf libpng-1.4.7.tar.gz
./configure
make && make install
注意： 64位系统需要拷贝
cp /usr/local/lib/libpng14.so.14 /lib64/
或者做软连接，不然执行gm命令的时候会报错！
cd
/opt/Source
wget http://downloads.sourceforge.net/project/graphicsmagick/graphicsmagick/1.3.16/GraphicsMagick-1.3.16.tar.gz
tar vxzf GraphicsMagick-1.3.16.tar.gz
cd GraphicsMagick-1.3.16
./configure
make&& make install

注意： 要建立路径
mkdir /usr/local/openresty/nginx/html/upload
给定写权限：
chmod o+w /usr/local/openresty/nginx/html/upload
拷贝测试图片：
cp test.jpg
/usr/local/openresty/nginx/html/upload/test.jpg
测试nginx语法：
/usr/local/openresty/nginx/sbin/nginx
-t
启动nginx
/usr/local/openresty/nginx/sbin/nginx
netstat -tunlp |grep :80
客户端浏览器测试：
http://Server_ip/upload/test.jpg
: 查看原图
http://Server_ip/upload/test.jpg.160x160.jpg
:查看缩放图
注意事项：
本文档关闭了selinux ，同时放行了80端口。
配置有问题可以查看nginx的错误日志文件！
tail -f /usr/local/openresty/nginx/logs/error.log
