Using nginx for acceleration

nginx is generally used as a reverse proxy server. And can proxy to any accessible node.

For example, we found that for a restful api website, the domestic access speed is not good. We can use nginx on an overseas node to accelerate.

First install nginx, and then modify nginx.conf as follows:

user  www;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    use   epoll;
    worker_connections  1024;
}

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

    server_tokens   off;

    #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;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    gzip  on;

    map $http_upgrade $connection_upgrade {
        default upgrade;
        '' close;
    }

    proxy_ssl_server_name on;

    ssl_protocols SSLv2 SSLv3 TLSv1 TLSv1.1 TLSv1.2;

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

Among them, map $http \ \ upgrade $connection \ \ upgrade is to support websocket. The proxy_ssl_server_name and ssl_protocols are used to better proxy https sites, and then the specific acceleration agent length is in / etc/nginx/conf.d/*.conf;.

/Write a PROXY.conf in etc/nginx/conf.d /

server {
    listen       80;
    server_name  api2-poloniex-com.example.com;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;

    proxy_set_header Connection $connection_upgrade;
    location / {
        proxy_pass https://api2.poloniex.com;
        client_max_body_size 10m;
    }
}

server {
    listen       80;
    server_name  poloniex-com.example.com;
    location / {
        proxy_cookie_domain poloniex-com.example.com poloniex.com;
        proxy_cookie_domain poloniex.com poloniex-com.example.com;
        proxy_pass https://poloniex.com;
        client_max_body_size 10m;
    }
}

The first server is the proxy websocket, and Upgrade needs to be set. The second is the restful interface, which can set the cookie.
