介绍篇
反向代理
正向代理A想要认识CA没有办法直接跟C聊天所以A通过B把消息传给C。 反向代理表面上访问百度都是访问www.baidu.com实际上域名后面有N多具体的ip服务器。 区别是否对代理有感知有就是正向代理没有就是反向代理。
负载均衡
我有一台服务器负载100个请求我新增一台服务器通过负载均衡的配置例如轮训策略每一台服务器承担50个请求这种方式就称为负载均衡。
下载篇
http://nginx.org/en/download.html
Linux
第一步下载安装包
Windows
第一步下载安装包 第二步解压zip文件后文件目录如图所示 第三步启动nginx
输入命令nginx.exe 或 双击 nginx.exe 推荐使用命令行启动否则可能会启动多个nginx 第四步访问 http://localhost/。如果出现以下页面代表启动成功。 命令篇

反向代理
1 修改nginx.conf文件来实现代理www.baidu.com location /baidu {proxy_pass https://www.baidu.com/;}当访问 localhost:80/baidu路径的时候nginx已经帮我们反向代理到www.baidu.com域名下。
2 新增server块来代理9001本地服务 代理前
代理后 3 通过80端口代理本地服务9001配置文件新增内容 游览器效果图 4 通过80端口代理内网ip服务效果图
nginx.conf内容
游览器效果图
负载均衡 upstream srv{server 127.0.0.1:8091 weight1;server 127.0.0.1:8092 weight1;}location / {root html;index index.html index.htm;proxy_pass http://srv;}
