Nginx – worker_connections are not enough

kibananginx

I am trying access kibana application deployed in nginx,but getting below

URL :- http://127.0.0.1/kibana-3.1.2

2015/02/01 23:05:05 [alert] 3919#0: *766 768 worker_connections are not enough while connecting to upstream, client: 127.0.0.1, server: , request: "GET /kibana-3.1.2 HTTP/1.0", upstream: "http://127.0.0.1:80/kibana-3.1.2", host: "127.0.0.1"

Kibana is deployed at /var/www/kibana-3.1.2

I have tried to increase the worker_connections,but still no luck,getting below in this case.

2015/02/01 23:02:27 [alert] 3802#0: accept4() failed (24: Too many open files)
2015/02/01 23:02:27 [alert] 3802#0: accept4() failed (24: Too many open files)

2015/02/01 23:02:27 [alert] 3802#0: accept4() failed (24: Too many open files)

nginx.conf :-

user www-data;
worker_processes 4;
pid /var/run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

And below in the location directive.

location /kibana-3.1.2{

        proxy_set_header X-Real-IP  $remote_addr;

        proxy_set_header X-Forwarded-For $remote_addr;

        proxy_set_header Host $host;

        proxy_pass http://127.0.0.1;

        add_header Access-Control-Allow-Origin *;

        add_header Access-Control-Allow-Headers *;
       }

Old question, but i had the same issue and the accepted answer didnt work for me.

I had to increase the number of worker_connections, as stated here.

/etc/nginx/nginx.conf

events {
    worker_connections 20000;
}
