nginx 请求头过大导致502，nginx报错： 2020/04/26 21:57:45 [error] 3152#3152: *5 upstream sent too big header while reading response header from upstream, client: 1.80.1.176, server: www.zeekling.cn, request: "GET /articles/2020/04/13/1586788757454.html HTTP/2.0", upstream: "http://127.0.0.1:8080/articles/2020/04/13/1586788757454.html", host: "www.zeekling.cn", referrer:"https://www.zeekling.cn/articles/2019/09/07/1587898561235.html"
博客从solo迁移到bolo后，点击链接报502错误。查看nginx的error.log发现报错信息是'upstream sent too big header'。通过增加nginx.conf配置解决问题。
