Load balancing


I am new to NGINX and I was trying to use NGINX as load balancer, but
somehow it didn’t work. here is my configuration.

worker_processes 1;

error_log /var/log/nginx/error.log info;

events {
worker_connections 1024;

http {
include mime.types;
default_type application/octet-stream;

log_format  main  '$remote_addr - $remote_user [$time_local]

“$request” ’
'"$status" $body_bytes_sent “$http_referer” ’
‘"$http_user_agent" “$http_x_forwarded_for”’;

access_log  logs/access.log  main;

sendfile        on;

keepalive_timeout  65;

upstream mysvr {
server server1.com;
server server2.com;

server {
    listen       80;
    server_name  www.mainserver.com mainserver.com;
    charset utf-8;

    access_log /var/log/nginx/localhost.log;
   error_log /var/log/nginx/error.log debug;

location / {
proxy_max_temp_file_size 0;

            client_max_body_size       10m;
            client_body_buffer_size    128k;

            proxy_connect_timeout      90;
            proxy_send_timeout         90;
            proxy_read_timeout         90;

            proxy_buffer_size          4k;
            proxy_buffers              4 32k;
            proxy_busy_buffers_size    64k;
            proxy_temp_file_write_size 64k;

        root   html;
        index  index.html index.htm;

        proxy_pass      http://mysvr;

        proxy_set_header  X-Forwarded-For

proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_set_header Host $host;


This is just a simple load balancing. When i request the mainserver.com,
the page didn’t even show up. When i checked the log, it said “[alert]
13442#0: *1013 socket() failed (24: Too many open files) while
connecting to upstream”. If i comment the “proxy_pass” line, it will
work, any help is appreciated.

Thank You…
