Nginx返回110连接超时

nginx错误日志

2013/08/14 01:06:25 [error] 29031#0: *19429255 connect() failed (110: Connection timed out) while connecting to upstream, client: ***.***.***.***, server: d.localhost.com, request: "GET /dashboard/d HTTP/1.1", upstream: "http://0.0.0.0:9000/dashboard/d", host: "d.localhost.com", referrer: "http://d.localhost.com/"

我使用nginx服务资源文件并减少播放负载但仍然出现此错误试过增加了 proxy_connect_timeout，send_timeout，proxy_read_timeout但错误仍然存在即使服务器负载很低，它也会引发这些错误

这会经常发生不同的请求

我的nginx配置是

upstream dWeb {
server 0.0.0.0:9000; 
}
server {
listen 80;
client_max_body_size 50M;
server_name  d.localhost.com;
root /home/web/d-web;
send_timeout 20;
location /
{
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_redirect off;
    proxy_max_temp_file_size 0;
    proxy_connect_timeout 10000;
    send_timeout 10000;
    proxy_read_timeout 10000;
    keepalive_timeout 10000;
    root /home/web/dsp-web/d-web-0.1.0;
    autoindex on;
    proxy_pass http://dWeb;
    error_log /data/nginxlog/d.rd/error.log;
}
}

实际问题是播放无法处理发送给它的所有请求以及最终连接超时

就像增加nginx中的工作者一样，我们必须增加线程池以提高并行性能

覆盖默认线程池以提高性能

默认配置

play {
  akka {
    event-handlers = ["akka.event.Logging$DefaultLogger","akka.event.slf4j.Slf4jEventHandler"]
    loglevel = WARNING
    actor {
      default-dispatcher = {
        fork-join-executor {
          parallelism-factor = 1.0
          parallelism-max = 24
        }
      }
    }
  }
}

parallelism-factor是每个可用核心要创建的线程数把它增加到4 因为每个请求有很多读写操作

覆盖配置 并行因子= 4.0 parallelism-max = 24

这停止了110超时错误

110连接超时 - 使用play 2.1.3和nginx
