Pre-test Configuration

The nginx application is installed on system-2 and is configured as follows.

The /etc/nginx/nginx.conf file is shown below. Changes from the distributed file are highlighted :

user                        nginx;
worker_processes            3;
worker_cpu_affinity         auto 1110;
error_log                   /var/log/nginx/error.log warn;
pid                         /var/run/nginx.pid;
events {
    worker_connections      1024;
}
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              off;
    sendfile                off;
    keepalive_timeout       300s;
    keepalive_requests      1000000;
    open_file_cache         max=1000 inactive=20s;
    open_file_cache_valid   30s;
    open_file_cache_errors  off;
    include                /etc/nginx/conf.d/*.conf;
}

The /etc/nginx/conf.d directory contains only the default.conf file, shown below. Changes from the distributed file are highlighted:

server {
    listen       nn.nn.nn.nn:80 reuseport;
    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

where nn.nn.nn.nn is the IP address of the system-2 adapter port that will receive the HTTP requests.

A zero-byte file is created in the root of the nginx server:

# touch /usr/share/nginx/html/0kb.bin
