无法在启用粘性模块的情况下启动nginx 1.9.4 [英] Unable to start nginx 1.9.4 with a sticky module enabled

问题描述

我在云实例上安装了nginx 1.9.4.但是启用粘性模块后，无法使用"sudo service nginx start"启动nginx.但是将其删除后，便可以启动它了.有谁知道导致这个问题的原因?

I have nginx 1.9.4 install on my cloud instance. But I'm unable to start nginx with "sudo service nginx start" when sticky module is enabled. But when this is removed I am able to start it. Has anyone got an idea about what's causing this issue?

upstream uesconf 
{

sticky;

    server xxx.xxx.xxx.xxx:9443;
    server xxx.xxx.xxx.xxx:9443;
    server xxx.xxx.xxx.xxx:9443;
    server xxx.xxx.xxx.xxx:9443;


}

server {

    listen   80;
    server_name xxx.xxx.xxx;
    rewrite ^/(.*) http://xxx.xxx.xxx/$1 permanent;


    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;

}

server {

   listen 443;
   server_name xxx.xxx.xxx;

   ssl on;
   ssl_certificate /etc/nginx/conf.d/keys/xxx.crt;
   ssl_certificate_key /etc/nginx/conf.d/keys/xxx.key;

    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;
    client_max_body_size 20M;


   location / {
       index index.html;
       proxy_set_header X-Forwarded-Host $host;
       proxy_set_header X-Forwarded-Server $host;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

       proxy_set_header Host $http_host;
       proxy_read_timeout 5m;
       proxy_send_timeout 5m;

       proxy_pass https://uesconf;
       proxy_redirect https://uesconf https://xxx.xxx.xxx/;

   }

}

推荐答案

不是使用粘性会话，而是尝试根据每个客户端使用标准方法来重用同一服务器IP:

Rather than using sticky session try to handle standard way to reuse the same server IP according to each client:

upstream backend {
    hash $remote_addr consistent;

    server backend1.example.com;
    server backend2.example.com;
}

您的情况如下:

upstream uesconf {
    hash $remote_addr consistent;
    server xxx.xxx.xxx.xxx:9443;
    server xxx.xxx.xxx.xxx:9443;
    server xxx.xxx.xxx.xxx:9443;
    server xxx.xxx.xxx.xxx:9443;
}
