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. --------------------------------------------------------------------干货https://www.cnblogs.com/fengff/p/8892590.html--------
  6. PS:nginx 的安装路径 /usr/local/nginx
  7. Ngxin默认端口是80

  8. 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。  

 

 

PS: Nginx定时日志输出配置

 

 --------------------------------------------------

PS: 一个Server下可以配置多个location

 

 

#user  nobody;

#开启进程数 <=CPU数 
worker_processes  1;

#错误日志保存位置
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#进程号保存文件
#pid        logs/nginx.pid;

#每个进程最大连接数（最大连接=连接数x进程数）每个worker允许同时产生多少个链接，默认1024
events {
    worker_connections  1024;
}


http {
    #文件扩展名与文件类型映射表
    include       mime.types;
    #默认文件类型
    default_type  application/octet-stream;

    #日志文件输出格式 这个位置相于全局设置
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    #请求日志保存位置
    #access_log  logs/access.log  main;
    
    #打开发送文件
    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    #连接超时时间
    keepalive_timeout  65;

    #打开gzip压缩
    #gzip  on;
    
    #设定请求缓冲
    #client_header_buffer_size 1k;
    #large_client_header_buffers 4 4k;
    
    #设定负载均衡的服务器列表
    #upstream myproject {
        #weigth参数表示权值，权值越高被分配到的几率越大
        #max_fails 当有#max_fails个请求失败，就表示后端的服务器不可用，默认为1，将其设置为0可以关闭检查
        #fail_timeout 在以后的#fail_timeout时间内nginx不会再把请求发往已检查出标记为不可用的服务器
    #}
    
    #webapp
    #upstream myapp {   
      # server 192.168.1.171:8080 weight=1 max_fails=2 fail_timeout=30s;

    #配置虚拟主机，基于域名、ip和端口

        #监听端口

        #charset koi8-r;
        
        #nginx访问日志放在logs/host.access.log下，并且使用main格式（还可以自定义格式）
        #access_log  logs/host.access.log  main;

        #返回的相应文件地址
        location / {
            #设置客户端真实ip地址
