无法在启用粘性模块的情况下启动 nginx 1.9.4

Question

我的云实例上安装了 nginx 1.9.4。但是启用粘性模块后，我无法使用“sudo service nginx start”启动 nginx。但是当它被删除时，我可以启动它。有没有人知道是什么导致了这个问题？

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/;

   }

}

Answer 1

而不是使用粘性会话尝试处理标准的方式来根据每个客户端重用相同的服务器 IP：

upstream backend {
    hash $remote_addr consistent;

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

你的情况如下：

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;
}
