Nginx如何配置多个服务域名解析共用80端口详解

通过apt-get install nginx命令安装的nginx默认配置文件存放在：/etc/nginx目录下
 
切换到/etc/nginx目录
 
#cd /etc/nginx           #切换到nginx目录
 
# ls                     #查看nginx目录下文件
conf.d        fastcgi_params  koi-win     modules-available  nginx.conf    scgi_params      sites-enabled  uwsgi_params fastcgi.conf  koi-utf         mime.types  modules-enabled    proxy_params  sites-available  snippets       win-utf
 
#vim nginx.conf          #打开nginx配置文件（输入shift+i插入内容，esc退出编辑，点击shift+：输入q退出当前页，q！强制退出，不保存编辑的内容；输入wq！强制退出并保存）

1.先配置两个端口服务：
// nginx.conf
#demo
server {
    listen       8001;
    server_name localhost;
    try_files $uri $uri/ /index.html;
    root    /home/www/demo;
}
#product
server {
    listen        8002;
    server_name  localhost;
    try_files $uri $uri/ /index.html;
    root    /home/www/product;
}
 
2.配置代理：
// nginx.conf
#demo转发
server {
    listen       80;
    server_name demo.test.com;
    location / {
        proxy_pass http://localhost:8001;
    }
}
#product转发
server {
    listen       80;
    server_name product.test.com;
    location / {
        proxy_pass http://localhost:8002;
    }
}

#systemctl restart nginx

// nginx.conf
# nginx 80端口配置 （监听demo二级域名）
server {
    listen  80;
    server_name     demo.test.com;
    location / {
        root   /home/www/demo;
        index  index.html index.htm;
    }
}
 
# nginx 80端口配置 （监听product二级域名）
server {
    listen  80;
    server_name     product.test.com;
    location / {
        root   /home/www/product;
        index  index.html index.htm;
    }
}
