宝塔 Nginx反向代理/CDN缓存加速设置-陌上烟雨遥

宝塔面板自带了反向代理设置, 通过Nginx反向代理我们可以让网站达到加速的效果, 如果开启缓存还可以减少源服务器带宽压力,现在简单说说这个设置.

以imotao.com为例
若www.imotao.com源服务器为A, 反代节点服务器为B和C.
假设源服务器A的IP为:

1.1.1.1

反代节点服务器B和C

2.2.2.2
3.3.3.3

首先要在反代服务器节点(B和C)上设置hosts.


<span class="hljs-attribute">vi</span> /etc/hosts 
<span class="hljs-attribute">vi</span> /etc/hosts 
vi /etc/hosts

输入源服务器A的IP地址, 如


1.1.1.1 <span class="hljs-selector-tag">www</span><span class="hljs-selector-class">.imotao.com</span> 
1.1.1.1 <span class="hljs-selector-tag">www</span><span class="hljs-selector-class">.imotao.com</span> 
1.1.1.1 www.imotao.com

再进反代节点服务器(B和C)的宝塔控制面板设置相关信息
目标地址输入您需要反代的URL地址, 也就是www.imotao.com
发送地址:$host
再选择启用反向代理和开启缓存

如果您的网站已经开启SSL访问, 那么还需要添加SSL证书.

另外缓存的配置文件位于


/www/server/nginx/conf/proxy.conf 
/www/server/nginx/conf/proxy.conf 
/www/server/nginx/conf/proxy.conf

其中一台服务器的配置文件

设置完成后您就可以把域名解析到节点服务器上了.

查看缓存是否生效, 访问一次后查看缓存目录下面有没有文件, 如果有就说明缓存成功了.
以下是我自定义的缓存目录:


/home/<span class="hljs-keyword">cache</span>/proxy_cache_dir 
/home/<span class="hljs-keyword">cache</span>/proxy_cache_dir 
/home/cache/proxy_cache_dir
