4-5 HTTP2的优势和Nginx配置HTTP2的简单使用

Http2的优势：

http2的配置：

proxy_cache_path cache levels=1:2 keys_zone=my_cache:10m;


server {#由http跳转到https
  listen       80 default_server;
  listen       [::]:80 default_server;
  server_name  test.com;
  return 302 https://$server_name$request_uri;
}

server {
  listen       443 http2;
  server_name  test.com;
  http2_push_preload on;#开启http2的push

  ssl on;
  ssl_certificate_key /usr/local/etc/nginx/certs/localhost-privkey.pem;
  ssl_certificate /usr/local/etc/nginx/certs/localhost-cert.pem;

  location / {
    proxy_cache my_cache;
    proxy_pass http://127.0.0.1:8888;
    proxy_set_header Host $host; #nginx对http请求的host进行转发
  }
}
