详述Linux系统中Nginx虚拟主机的配置

Nginx虚拟主机应用

Nginx支持的虚拟主机有三种

• 基于域名的虚拟主机.
• 基于IP的虚拟主机
• 基于端口的虚拟主机

通过"server{}"配置段实现

• 本篇实验接着上一篇搭建Nginx服务继续搭建，前面Nginx的编译安装不在介绍

  基于域名的虚拟主机

  [root@localhost html]# echo "this is accp web" > accp/index.html  //创建站点文件
  [root@localhost html]# ls accp/   //查看accp站点目录

• 在客户机中访问测试

基于不同IP的虚拟主机
