Nginx support TCP Load balance

1. Install nginx package

2. edit nginx configuration file

[root@ip- nginx]# more nginx.conf

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;

events {
    worker_connections  ;
}

http {
    include       /etc/nginx/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  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  ;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

# TCP/UDP proxy and load balancing block

stream {
    # Example configuration for TCP load balancing

    upstream stream_ota {
        zone tcp_servers 64k;
        server 10.xx.xx.32:22;
        server 10.xx.xx.12:22;
    }

    server {
        listen 2222;
        status_zone tcp_server;
        proxy_pass stream_ota;
        error_log /var/log/nginx/dgram-2222.log debug;
    }
}

3. Start service
