Nginx 配置 Google Ajax、 Fonts和 Gravatar 反向代理教程

Nginx 是最快和最强大的 Web 服务器之一，以其高性能和低资源占用率而闻名。它既可以被安装为一个独立的 Web 服务器，也可以安装成反向代理 Web 服务器。

nginx反向代理的指令不需要新增额外的模块，默认自带proxy_pass指令，只需要修改配置文件就可以实现反向代理。

首先我们需要建立用来存储缓存的目录：

mkdir -p /var/cache/nginx/cache
mkdir -p /var/cache/nginx/temp

修改 nginx 配置文件，加入

        ##
        # Nginx Cache Settings
        ##

        proxy_temp_file_write_size 128k;
        proxy_temp_path   /var/cache/nginx/temp;
        proxy_cache_path  /var/cache/nginx/cache levels=1:2 keys_zone=cache_one:50m inactive=7d max_size=5g;

以下是分别的配置文件：
