一 nginx的概念和作用
1.1 概念
1.nginx是一个代理静态资源的高性能http服务器和反向代理的服务器。
1.2 作用
1.代理静态资源：可以做静态网页的http服务器。
2.反向代理、负载均衡。：把请求转发给不同的服务器
3.解决跨域
4.配置虚拟机。
一个域名可以被多个ip绑定。可以根据域名的不同吧请求转发给运行在不同端口的服务器
1.3 启动关闭
1.启动： 在nginx目录下有一个sbin目录，sbin目录下有一个nginx可执行程序： ./nginx
2.查看nginx的进程
3.关闭
关闭命令：相当于找到nginx进程kill。
./nginx -s stop
退出命令：
./nginx -s quit
等程序执行完毕后关闭，建议使用此命令。
4.重新加载
./nginx -s reload可以不关闭nginx的情况下更新配置文件。
二 静态资源代理
2.1 nginx的配置
1.config的配置
2.存放的实际资源
3.访问页面
三 虚拟主机
3.1 同一台nginx，不同端口号虚拟两台服务器(ip)
nginx的配置文件：
1.第一个server块
2.第二个server块：
3.资源位置：
访问80：
访问8081：
3.2 使用域名存储静态资源
1.配置nginx的配置文件
2.修改host文件
3.启动服务，进行访问
3.3 同一台nginx，相同端口，虚拟两台不同域名的服务器(域名)
1.修改nginx配置文件
2.host文件配置
3.页面访问，相同端口，不同域名，进行访问
四 反向代理：8080端口代理成80端口
tomcat的服务访问地址： http://localhost:8080/nginx-demo/index.html
被代理后的地址： http://localhost/nginx-demo/index.html
4.1 nginx配置
4.2 tomcat的启动
4.3 访问
五 负载均衡
六 同一台nginx代理多个不同的静态资源
80端口 下 存储 vue的静态页面： html/dky-guolu-vue
新建一个server块，端口为8099，创建一个存储react静态页面： html/dky-guolu-react/；
#前端react页面
server {
listen 8099;
server_name localhost; location / {
root html/dky-guolu-react/;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}并且将react代理到80端口下，配置如下配置 ：
#前端react的页面
location /react {
proxy_pass http://32.32.255.239:8099/;
#root html;
#index index.html index.htm;
}访问地址：http://32.32.255.239:80/react/index.html
原先地址：http://32.32.255.239:8099/index.html
