1)https://github.com/LuaDist/luaxml下载压缩包解压到指定目录

2)修改Makefile文件

   INCDIR = -I/usr/local/openresty/luajit/include/luajit-2.1

   LIBDIR =  -L. -L/usr/local/openresty/luajit/lib

   LIBS          = $(LIBDIR) $(LIB) -lluajit-5.1 -ldl

   LIBS          = $(LIBDIR) -L/usr/local/lib $(LIB) -lluajit-5.1

3)make clean * make

4)拷贝LuaXML_lib.so以及LuaXml.lua到/usr/local/openresty/lualib/

5)然后使用的时候遇到了找不到动态链接库的问题

   cat /etc/ld.so.conf

   echo "/usr/local/openresty/luajit/lib/" >> /etc/ld.so.conf

   ldconfig
