为什么？

自从将博客平台更换为Sonic后，访问速度快了很多，但我想要更快，对后端压力更小，因此我想到了使用Nginx缓存对外展示的内容。以下是本网站的一些配置仅供参考。

Ngxin配置

首先在Nginx配置文件（/etc/nginx/nginx.conf）中的http { }中添加以下内容

  # 设置缓存文件位置，并配置缓存文件最大值
  proxy_cache_path /tmp/cache levels=1:2 keys_zone=cache_one:100m inactive=1d max_size=10g;
  # 关闭显示Nginx版本
  server_tokens off;
  # 开启ETAG功能
  etag on;

修改sonic.conf内容如下

server {
     listen 80
     listen [::]:80

     server_name www.itansuo.info;

     client_max_body_size 5m;
     client_body_timeout 60;

     access_log  /tmp/logs/sonic.log;

     gzip on;
     gzip_types application/xml application/json text/css text/javascript application/javascript;
     gzip_vary on;
     gzip_comp_level 6;
     gzip_min_length 500;

     location / {
         proxy_pass https://源站;
         proxy_redirect off;
         proxy_set_header Host $host;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header X-Forwarded-Proto $scheme;

         proxy_ssl_name $host;
         proxy_ssl_server_name on;

     }
