nginx tomcat7 错误：-“从上游读取响应标头时，recv() 失败（104：对等连接重置）”

Posted 2023-02-24

【中文标题】nginx tomcat7 错误：-“从上游读取响应标头时，recv() 失败（104：对等连接重置）”

【英文标题】：nginx tomcat7 ERROR : - “recv() failed (104: Connection reset by peer) while reading response header from upstream”

【发布时间】：2018-02-21 07:39:59

【问题描述】：

我的 nginx 日志中有两种类型的错误。

Error-1 connect() 在连接时失败（110：连接超时） 到上游

Error-2 recv() 在读取时失败（104：连接被对等方重置） 来自上游的响应头

所以我的上游是 Tomcat7 和前端的 Nginx。

我不明白为什么会出现此错误。因为，当我在 8080 端口上点击 tomcat7 时，它的负载很重。但是当 Nginx（在端口 80 上运行）上的高负载命中时，代理对 tomcat7 的请求会因这 2 个错误而失败。我能得到的所有答案都是 php-FPM，但我没有使用它。我不知道如何解决。

【问题讨论】：

发布你的 nginx 配置。使用nginx -T 并将其输出作为配置发布

嗨，Tarun，编辑了我的问题，您可以查看我的“nginx -T”结果。

您的超时时间太长了。将它们降低到 90、120、150、180 之类的值，然后尝试您的配置。

【参考方案1】：

我最终使用了以下配置：-

我们必须加快内部代码，即代码执行时间。现在每个请求花费的时间不到 50 毫秒。

使用的 Nginx 配置是：-

user www-data;
worker_processes auto;
worker_rlimit_nofile 10000;
pid /run/nginx.pid;

    worker_connections 2000;
    multi_accept on;
