python – Tornado,Nginx,Apache ab – apr_socket_recv:通过对等方重置连接(104)

前端之家收集整理的这篇文章主要介绍了python – Tornado,Nginx,Apache ab – apr_socket_recv:通过对等方重置连接(104)前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

我在c1.medium实例上运行Nginx和tornado.

当我跑ab时,下面是我的输出. Nginx不起作用.我试图调整ninx的配置文件无济于事.如果我通过传递Nginx只运行一个端口,例如`

  http://127.0.0.1:8050/pixel?tt=ff` 

然后它快.看到最底层.这必须是一个Nginx问题,所以如何解决?以下是Nginx的conf文件.

root@ip-10-130-167-230:/etc/service# ab -n 10000 -c 50 http://127.0.0.1/pixel?tt=ff

这应该吸烟,但事实并非如此.

我设置了以下parmamerts

ulimit is at 100000

# General gigabit tuning:
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
net.ipv4.tcp_syncookies = 1
# this gives the kernel more memory for tcp
# which you need with many (100k+) open socket connections
net.ipv4.tcp_mem = 50576   64768   98152
net.core.netdev_max_backlog = 2500

这是我的Nginx conf:

user www-data;
worker_processes 1;  # 2*number of cpus
pid /var/run/Nginx.pid;
worker_rlimit_nofile 32768;
events {
         worker_connections  30000;
         multi_accept on;
         use epoll;
}

http {
        upstream frontends {
          server 127.0.0.1:8050;
          server 127.0.0.1:8051;
        }
        sendfile on;
        tcp_nopush on;

        # server_tokens off;
        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;

        include /etc/Nginx/mime.types;
        default_type application/octet-stream;

        # Only retry if there was a communication error,not a timeout
    # on the Tornado server (to avoid propagating "queries of death"
    # to all frontends)
    proxy_next_upstream error;

        server {
        listen   80;
        server_name 127.0.0.1;
                ##For tornado
                location / {
                    proxy_pass_header Server;
                    proxy_set_header Host $http_host;
                    proxy_redirect off;
                    proxy_set_header X-Real-IP $remote_addr;
                    proxy_set_header X-Scheme $scheme;
                    proxy_pass http://frontends;
                }

如果我通过传递Nginx来运行ab:

ab -n 100000 -c 1000 http://127.0.0.1:8050/pixel?tt=ff



root@ip-10-130-167-230:/home/ubuntu/workspace/rtbopsConfig/rtbServers/rtbTornadoServer# ab -n 100000 -c 1000 http://127.0.0.1:8050/pixel?tt=ff

最佳答案
我使用webrick在sinatra应用程序上使用apache基准测试时遇到了同样的问题.我找到了答案here.

它实际上是Apache服务器的问题.

错误已在更高版本的apache中删除.尝试下载它们here.
