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cs.iocc.online为例
• 若cs.iocc.online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:173.82.206.56
• 反代节点服务器B和C:67.230.184.21 / 47.74.192.19

1. 首先要在反代服务器节点(B和C)上设置 hosts.

   vi /etc/hosts

2. 输入源服务器A的IP地址, 如

   173.82.206.56   cs.iocc.online

   

3. 在反代服务器节点(B和C)上宝塔面板里新建网站：
   
4. 在宝塔网站设置内，添加反向代理：
   

5. 修改反代配置文件，添加如下代码：
