Server STB – Cara NGINX untuk Performa Terbaik di STB. Untuk konfigurasi ini Anda dapat menggunakan web server yang Anda suka, dalam artikel ini maka saya memutuskan untuk menggunakan nginx sebagai web server.

Secara umum, nginx yang dikonfigurasi dengan benar dapat menangani hingga 400K hingga 500K permintaan per detik (berkelompok), sebagian besar yang terlihat adalah 50K hingga 80K (tidak berkerumun) permintaan per detik dan 30% beban CPU, tentu saja, ini adalah 2 x Intel Xeon dengan HyperThreading yang diaktifkan, dan dapat bekerja tanpa masalah pada mesin yang lebih lambat.

Anda harus memahami bahwa konfigurasi ini digunakan dalam lingkungan pengujian dan bukan dalam produksi sehingga Anda perlu menemukan cara untuk mengimplementasikan sebagian besar fitur tersebut sebaik mungkin untuk server Anda.

Pertama Install Nginx

yum install nginx

apt install nginx

Backup konfigurasi aslinya dan Anda dapat mulai mengkonfigurasi ulang. Anda harus membuka nginx.conf dengan menggunakan editor yang anda sukai :
/etc/nginx/nginx.conf

 

# you must set worker processes based on your CPU cores, nginx does not benefit from setting more than that

worker_processes auto; #some last versions calculate it automatically


# number of file descriptors used for nginx

# the limit for the maximum FDs on the server is usually set by the OS.

# if you don't set FD's then OS settings will be used which is by default 2000

worker_rlimit_nofile 100000;


# only log critical errors

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


# provides the configuration file context in which the directives that affect connection processing are specified.

events {

    # determines how much clients will be served per worker

    # max clients = worker_connections * worker_processes

    # max clients is also limited by the number of socket connections available on the system (~64k)

    worker_connections 4000;


    # optimized to serve many clients with each thread, essential for linux -- for testing environment

    use epoll;


    # accept as many connections as possible, may flood worker connections if set too low -- for testing environment

    multi_accept on;

}


http {

    # cache informations about FDs, frequently accessed files

    # can boost performance, but you need to test those values

    open_file_cache max=200000 inactive=20s;

    open_file_cache_valid 30s;

    open_file_cache_min_uses 2;

    open_file_cache_errors on;


    # to boost I/O on HDD we can disable access logs

    access_log off;


    # copies data between one FD and other from within the kernel

    # faster than read() + write()

    sendfile on;


    # send headers in one piece, it is better than sending them one by one

    tcp_nopush on;


    # don't buffer data sent, good for small data bursts in real time

    tcp_nodelay on;


    # reduce the data that needs to be sent over network -- for testing environment

    gzip on;

    # gzip_static on;

    gzip_min_length 10240;

    gzip_comp_level 1;

    gzip_vary on;

    gzip_disable msie6;

    gzip_proxied expired no-cache no-store private auth;

    gzip_types

        # text/html is always compressed by HttpGzipModule

        text/css

        text/javascript

        text/xml

        text/plain

        text/x-component

        application/javascript

        application/x-javascript

        application/json

        application/xml

        application/rss+xml

        application/atom+xml

        font/truetype

        font/opentype

        application/vnd.ms-fontobject

        image/svg+xml;


    # allow the server to close connection on non responding client, this will free up memory

    reset_timedout_connection on;


    # request timed out -- default 60

    client_body_timeout 10;


    # if client stop responding, free up memory -- default 60

    send_timeout 2;


    # server will close connection after this time -- default 75

    keepalive_timeout 30;
