Nginx学习安装配置和Ftp配置安装

1. 什么是代理？
2. 什么是正向代理？
3. 什么是反向代理？
4. Nginx与负载均衡有什么联系？
5. 如何在centos7 中安装Nginx-------------安装配置-----------------------------
6. --------------------------------------------------------------------干货https://www.cnblogs.com/fengff/p/8892590.html--------
7. PS:nginx 的安装路径 /usr/local/nginx
8. Ngxin默认端口是80

9. PS: nginx 配置虚拟主机的三种方法

PS:

html就是基础的root目录

sbin放置脚本文件的地方，启动和关闭

PS：安装时候遇见的问题
1.无法访问客户端
解决办法： 把防火墙关掉
2.不显示nginx页面，在nginx 配置页面添加 index.html

Ps:最最重要的就是看日志

----------------------配置文件讲解

PS: 一个Server就是一个虚拟主机

PS: 生产上会有F5，F5下面会挂载几个nginx，nginx会跳转不同节点上（跳转就是在本地配置的），upstream实现不同机器的配置

下面演示nginx配置访问

1.docker启动两个节点

2.nginx配置，访问那两个节点； 访问localhost：80/login的时候跳转到我的那两个节点

}

3.访问验证

PS: 一旦链接，secureCRT的链接就断开了

PS : 需要把nginx的根目录指向ftp上传文件的目录。
