nginx+redis +lua脚本实现nginx 302临时跳转

实现过程:
  nginx+redis +lua的环境,前一篇博文已经部署好
  在服务器上安装好redis后,记得要安装php的redis扩展,由于开发语言是php,所以要安装redis的扩展,这样才能php程序操作redis,
  php脚本存入key到redis中,通过请求url来实现nginx 302跳转
  在nginx.conf文件中http标签添加如下内容:
  

# grep lua /usr/local/nginx/conf/nginx.conf  lua_package_path "/usr/local/nginx/lua/lua-resty-redis/lib/?.lua;;";
  lua_shared_dict cache_ngx 128m;
  
# grep vhost /usr/local/nginx/conf/nginx.conf
  
include vhost/*.conf;
  

  配置nginx虚拟主机www.iuiodp.cn.conf
  

# cat /usr/local/nginx/conf/vhost/www.iuiodp.cn.conf  
server {
  listen       80;
  server_namewww.iuiodp.cn iuiodp.cn;
  index index.html index.htm index.php;
  root /data/www/www.iuiodp.cn;
  location ~ .*\.(php|php5)?$
  {
  #fastcgi_pass127.0.0.1:9000;
  fastcgi_passunix:/tmp/php-cgi.sock;
  fastcgi_index index.php;
  include fastcgi.conf;
  }
  location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
  {
  expires 30d;
  }
  location ~ .*\.(js|css)?$
  {
  expires 1h;
  }
  location / {
  * contentbyluafile /usr/local/nginx/conf/lua/csu.lua;*
  }
  access_log/data/wwwlogs/iuiodp.cn_access.log;
  
}
  

  在location段中指定csu.lu脚本路径:
  

location / {  content_by_lua_file /usr/local/nginx/conf/lua/csu.lua;
  }
  

  csu.lua脚本如下:
  

# cat /usr/local/nginx/conf/lua/csu.lua  
local redis = require "resty.redis"
  
local cache = redis.new()
  
cache.connect(cache, '127.0.0.1', '6379')
  
local key = ngx.var.uri;
  
local res = cache:get(key)
  
if res == ngx.null then
  
local res = cache:get("/sp");
  
ngx.redirect(res)
  
else
  
ngx.redirect(res)
  
end
  

  服务器hosts文件本地解析:
  

# grep www.iuiodp.cn /etc/hosts  
21.15.1.44 www.iuiodp.cn
  

  登录redis 写入key值:
  

# redis-cli -h 127.0.0.1 -p 6379  
127.0.0.1:6379> get /
  
(nil)
  
127.0.0.1:6379> set / http://www.yt925.com
  
OK
  
127.0.0.1:6379> get /
  
"http://www.yt925.com"
  
127.0.0.1:6379> set /a http://www.jd.com
  
OK
  
127.0.0.1:6379> get /a
  
"http://www.jd.com"
  
127.0.0.1:6379>
  
127.0.0.1:6379> set /d http://www.test.com
  
OK
  
127.0.0.1:6379> get /d
  
"http://www.test.com"
  

  服务器上curl域名,实现了302临时跳转
  

# curl http://www.iuiodp.cn  

  
302 Found
  

  
302 Found
  
nginx
  

  

  

  
# curl http://www.iuiodp.cn/a
  

  
302 Found
  

  
302 Found
  
nginx
  

  

  
# curl http://www.iuiodp.cn/d
  

  
302 Found
  

  
302 Found
  
nginx
  

  

  

  windows本地hosts文件绑定21.15.1.44 www.iuiodp.cn
  浏览器请求www.iuiodp.cn 会直接跳转到http://www.yt925.com 这个网站的页面

  浏览器请求http://www.iuiodp.cn/a 会直接跳转到https://www.jd.com 官网页面

  浏览器请求http://www.iuiodp.cn/d会直接跳转到https://www.test.com 官网页面

  访问日志如下:

  演示到此处,跳转功能已经实现,尽情关注后续的博文,后续还有精彩的内容。同时也希望大家能互相交流学习
