nginx嘛，自不必说了，最好使的服务器软件之一。lua的特点，想必很多人也是心知肚明的。而OpenResty给我们看到了一种nginx的新玩法，那就是nginx+lua。
准备
首先，我们需要下载nginx1.12.0、luajit2.0.5以及lua-nginx-modulev0.10.9rc8，并把他们都存放在/root/src目录里面。他们在github上面的网址分别是https://github.com/nginx/nginx 、https://github.com/LuaJIT/LuaJIT 以及
https://github.com/openresty/lua-nginx-module

错误
编译安装nginx后，启动nginx的时候，可能会出现类似libluajit-5.1.so.2: cannot open shared object file的错误提示。那是因为系统找不到libluajit-5.1.so.2的原因，建立个软连接即可。
