  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 

#user  nobody;

worker_processes  1;

#error_log  logs/error.log;

#error_log  logs/error.log  notice;

#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {

    worker_connections  1024;

}

http {

    include       mime.types;

    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

    #                  '$status $body_bytes_sent "$http_referer" '

    upstream site {

        ip_hash;

        server 192.168.88.11:8081;

        server 192.168.88.11:8082;

    } 

    server {

        server_name  localhost;

        #access_log  logs/host.access.log  main;

        location /login {

            proxy_pass http://site;

        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html

        #

        error_page   500 502 503 504  /50x.html;

        location = /50x.html {

            root   html;

        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80

        #

        #    proxy_pass   http://127.0.0.1;

        #location ~ \.php$ {

        #    root           html;

        #    fastcgi_pass   127.0.0.1:9000;

        #    fastcgi_index  index.php;

        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

        #    include        fastcgi_params;

        #}

        # deny access to .htaccess files, if Apache's document root

        # concurs with nginx's one

        #

        #location ~ /\.ht {

        #    deny  all;

        #}

    }

    # another virtual host using mix of IP-, name-, and port-based configuration

    #

    #server {

    #    listen       8000;

    #    listen       somename:8080;

    #    server_name  somename  alias  another.alias;

    #    location / {

    #        root   html;

    #        index  index.html index.htm;

    #    }

    #}

    # HTTPS server

    #

    #server {

    #    listen       443 ssl;

    #    server_name  localhost;

    #    ssl_certificate      cert.pem;

    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;

    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;

    #    ssl_prefer_server_ciphers  on;

    #    location / {

    #        root   html;

    #        index  index.html index.htm;

    #    }

    #}

}

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。
