试验了几个反向代理,发现都面临一个问题

    这是一个创建于 2983 天前的主题,其中的信息可能已经有所发展或是发生改变。

    试验环境

    主机: Mac 运行 Valte 跑 phpcms 程序,不加任何反代在本机或在内网内打开 phpcms.dev 进行任何操作都不会有问题的。

    内网三台机器,全部最小化安装 ubuntu 14.04 lts , apt 直接安装各软件

    • 内网 A 机器: nginx 反代
    • 内网 B 机器: varnish 反代
    • 内网 C 机器: squid 反代

    配置都是直接拿官方教科书一般的配置文件,添加进去的配置少得可怜,连缓存都不会有的,不影响测试。

    nginx 配置:

    server {
      listen 80 default fastopen=256 reuseport;
      server_name _;
      access_log /var/log/nginx/proxy-access.log combined;
      error_log /var/log/nginx/proxy-error.log;
    
      resolver 8.8.4.4 8.8.8.8 valid=300s;
      resolver_timeout 10s;
    
      location / {
        proxy_pass http://172.16.1.168;
        include proxy.inc;
      }
    }
    

    varnish 配置: https://github.com/mattiasgeniar/varnish-4.0-configuration-templates/blob/master/default.vcl

    squid 配置只是在原有默认配置上加了cache_peer上游服务器,访问其他都是没问题,唯独这个 phpcms 的安装步骤。

    主要问题是在进行安装的第三步 post 数据时就一定过不去了,在 chrome 抓取到的错误信息如下:

    看到最后的 HTTP_TRANSACTION_READ_HEADERS ,耗时 24510 ,然后网页就返回无响应被重置了。

    在公网上放了个 phpcms ,然后用了腾讯云的 CDN 、百度云的 CDN 、还有 Keycdn ,
    腾讯云百度云都可以正常跳到后续的步骤, keycdn 过不去。

    是我漏掉哪个配置?
    第 2 条附言  ·  2016-10-29 02:36:14 +08:00

    之前附言不正确,腾讯云CDN 大部分节点的服务器都没法正常走完整个流程,遇到的问题和本地测试的情况是一致的。除了用 chrome 进行测试,可以用 curl 模拟提交,后端无法返回数据。

    curl 命令:

    $ curl -v -H "Transfer-Encoding: chunked" -H "Content-Type: application/x-www-form-urlencoded" -d "step=4&install_phpsso=1&sso%5Bsso_url%5D=http%3A%2F%2F127.0.0.1%2Fphpsso_server%2F&sso%5Busername%5D=&sso%5Bpassword%5D=&selectmod%5B%5D=announce&selectmod%5B%5D=comment&selectmod%5B%5D=link&selectmod%5B%5D=vote&selectmod%5B%5D=message&selectmod%5B%5D=mood&selectmod%5B%5D=poster&selectmod%5B%5D=formguide&selectmod%5B%5D=wap&selectmod%5B%5D=upgrade&selectmod%5B%5D=tag&selectmod%5B%5D=sms&testdata=1" http://examples.com/install/install.php?
    

    在不借助各种反代服务器,直接访问后端的服务器,在测试返回的数据中可以看到进行到了安装的第五步

    但在测试提交不成功返回的 response,是直接中断了输出:

    *   Trying 111.202.85.44...
    * Connected to examples.com (111.202.85.44) port 80 (#0)
    > POST /install/install.php? HTTP/1.1
    > Host: examples.com
    > User-Agent: curl/7.49.1
    > Accept: */*
    > Transfer-Encoding: chunked
    > Content-Type: application/x-www-form-urlencoded
    >
    > 190
    * upload completely sent off: 407 out of 400 bytes
    < HTTP/1.1 200 OK

    <
    * Recv failure: Connection reset by peer
    * Closing connection 0
    curl: (56) Recv failure: Connection reset by peer
    

    如果把post 过去表单的值减少到几个,那么这些反代服务器都能正确返回数据。

    @billlee 就几行:

    ```
    proxy_redirect off;
    proxy_set_header Accept-Encoding '';
    proxy_set_header Host $host;
    proxy_set_header Referer $http_referer;
    proxy_set_header Cookie $http_cookie;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-NginX-Proxy true;
