简单的灰度测试,lua或者直接改nginx配置

配置过程:

1、根据cookies特征值实现

在做的过程中把login的操作给做了过滤。登录过程将cookie中设置了一个新的cookie值 GINA_gray_SESSIONID =gray这样在nginx配置中

加入筛选

Root不要配置在最前面而是配置在location中

#过滤login 请求进来会优先判断 请求是不是/ gina-client/login 然后判断是不是 / gina-client/

location /client/login {
     proxy_pass http://client_stable_gray;
}

登陆过程加上cookie

 location /client/{
                set $group "client_stable";

if ( $http_cookie ~* "GINA_gray_SESSIONID = gray" ) {

                set $group "client_stable_gray";

}

               proxy_pass http://$group;
        }

筛选root

location / {

                 set root /data0/project/gina/html/agent;

                 if ( $http_cookie ~*"GINA_gray_SESSIONID = gray" ) {

                      set root /data0/project/gina/html/agent_gray/magneto/dist/agent;

                 }

        }

2、根据cookie ||||| lua 方式

如果单独抽出来写lua脚本

cookies_gray.lua

local uin = ngx.var.cookie_loginuin

--取cookies里的loginuin字段,末尾被2整数的灰度

if uin ~= nil and string.sub(uin,string.len(uin))%2 == 0then

  ngx.exec("@gray_env")

else

  ngx.exec("@product_env")

end

nginx.conf

  ...

  #http

  lua_code_cacheoff; #正式上线记得打开cache

  lua_package_path"/usr/local/openresty/lualib/?.lua;;";

  lua_shared_dictconfig 1m;

  ...

  #server

  location / {

     #access_by_lua_file  conf/lua/ip_gray.lua;

    access_by_lua_file conf/lua/cookies_gray.lua;

  }

  location@gray_env {

      proxy_passhttp://gray_env;

     proxy_set_header Host $http_host;

  }

  location@product_env {

      proxy_passhttp://product_env;

     proxy_set_header Host $http_host;

  }

cal uin = ngx.var.cookie_GINA_gray_SESSIONID

if uin ~= nil and uin == 'gray' then

 ngx.say("Gray Environment World")

 #ngx.exec("@gray_env")

else

 ngx.exec("@product_env")

end
