　　首先下载最新的openresty

　　接下来开始安装带lua模块的openresty

./configure --prefix=/home/app/ngx_openresty-1.7.7.7.2 --with-luajit --with-pcre=/home/download/pcre-7.8
　　安装redis
　　下载redis3.0

wget http://download.redis.io/releases/redis-3.0.0.tar.gz

　　nginx.conf

#usernobody;
worker_processes1;
#error_loglogs/error.log;
#error_loglogs/error.lognotice;
#error_loglogs/error.loginfo;
#pid      logs/nginx.pid;

events {
worker_connections1024;
}

http {
include       mime.types;
default_typeapplication/octet-stream;
log_formatmain'$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_loglogs/access.logmain;

local redis = require "resty.redis"
local cache = redis.new()
cache.connect(cache,'127.0.0.1',6379)
