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

Question

我的 nginx 日志中出现两种类型的错误。

Error-1 connect() failed (110: Connection timed out) while connecting to upstream

Error-2 recv() failed (104: Connection reset by peer) while reading response header from upstream

所以我的上游是前端的Tomcat7和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，它会承受很重的负载。但是当在 Nginx（端口 80 上的运行）上以高负载命中时，代理对 tomcat7 的请求因这两个错误而失败。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。

我最终使用了以下配置：-

我们不得不加快我们的内部代码，即代码执行时间。现在每个请求花费的时间少于 50 毫秒。
使用的 Nginx 配置是：-

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

events {
    worker_connections 2000;
    multi_accept on;
    use epoll;
}

http {
    open_file_cache max=200000 inactive=20s;
    open_file_cache_valid 30s;
    open_file_cache_min_uses 2;
    open_file_cache_errors on;
    reset_timedout_connection on;
    client_body_timeout 200s; # Use 5s for high-traffic sites
    client_header_timeout 200s;
