构建nginx lua redis高并发应用

 

    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

   

#user  nobody;
worker_processes  1;

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

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  logs/access.log  main;

    sendfile        on;

    keepalive_timeout  65;

    gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        access_log  logs/host.access.log  main;

        location / {
           # root   html;
           # index  index.html index.htm;
		proxy_pass http://sonicery_d.com;
        }
	location /syd{
		proxy_pass http://sonicery_d.com;
	}
	location /hello{
		root html;
	}
	location /testlua{
		default_type text/plain;
		content_by_lua_file /home/app/lua/test.lua;
	}
        error_page  404              /404.html;


        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)
