2018/10/29 16:07:47 [error] 1308#0: *636 connect() failed (113: No route to host) while connecting to upstream, client: XXX.XXX.XXX.XXX, server: XXX, request: "GET /static/css/base.css?v=3 HTTP/1.1", upstream: "http://XXX:80/static/css/base.css?v=3", host: "XXX", referrer: "https://XXX/"
查看nginx日志会出现上面的报错
体现到网页上就是会出现不能正常(完整)显示页面
绑定hosts直接访问源服务器是正常的
尝试了网上的方法,关闭防火墙,没有作用
然后抓包,发现tcp连接有异常
再做正反向路由追踪,发现往返路径不一致
反馈运营商调整路由出口就好了
