session和ip地址有hash关系，尤其在内外网替换不完全的时候,比如退出使用192.168.13.99/hb_phonebank_web/logout,
登录使用http://116.236.184.238:8006/hb_phonebank_web/，这时session对不上，明显的就是退出没有清掉，重新登录没有
换用户名
外网前端请求的要是外网地址（使用端能访问的地址），之后nginx再转为内网，upstream是nginx内部用的，nginx的装机地址才是外网要映射的地址
外网开映射：
116.236.184.238:8006 ---》 192.168.13.99:80
116.236.184.238:8007 ---》 192.168.13.99:8126
nginx实现：
外网 内网
服务端：http://116.236.184.238:8006/hb_phonebank_web/ ----》 http://192.168.13.99/hb_phonebank_web/
静态页面：http://116.236.184.238:8007/dashboard ----》 http://192.168.13.99:8126/dashboard
外网这种用端口映射的时候，可能会出现退出的时候丢失了端(http://116.236.184.238/hb_phonebank_web/ )，内网80可以省略所以没有问题，nginx 需配置proxy_set_header Host $http_host;
$host不能再用

shrio配置：
