4-4 使用Nginx部署HTTPS服务

生成免费ssl证书：

openssl req -x509 -newkey rsa:2048 -nodes -sha256 -keyout localhost-privkey.pem -out localhost-cert.pem

nginx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;
  server_name  test.com;

  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
  }
}

此时，无论访问http://test.com/还是https://test.com/都会跳转到https
