构建nginx lua redis高并发应用

爱在莫斯科

　　首先下载最新的openresty    

wget http://openresty.org/download/ngx_openresty-1.7.10.1.tar.gz
　　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
make install
　　然后配置一下nginx配置
　　nginx.conf

worker_processes  1;
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

}

error_page   500 502 503 504  /50x.html;
location = /50x.html {
root   html;
}
}


include upstream.conf;
}

　　test.lua

local redis = require "resty.redis"
local cache = redis.new()
cache.connect(cache,'127.0.0.1',6379)
local res = cache:get("foo")
if res == ngx.null then
ngx.say("This is null")
return
end
ngx.say(res)
